Texto completoThis thesis deals with the theory of margin multi-category classification, and is based on the statistical learning theory founded by Vapnik and Chervonenkis. We are interested in deriving generalization bounds with explicit dependencies on the number C of categories, the sample size m and the margin parameter gamma, when the loss function considered is a Lipschitz continuous margin loss function. Generalization bounds rely on the empirical performance of the classifier as well as its "capacity". In this work, the following scale-sensitive capacity measures are considered: the Rademacher complexity, the covering numbers and the fat-shattering dimension. Our main contributions are obtained under the assumption that the classes of component functions implemented by a classifier have polynomially growing fat-shattering dimensions and that the component functions are independent. In the context of the pathway of Mendelson, which relates the Rademacher complexity to the covering numbers and the latter to the fat-shattering dimension, we study the impact that decomposing at the level of one of these capacity measures has on the dependencies on C, m and gamma. In particular, we demonstrate that the dependency on C can be substantially improved over the state of the art if the decomposition is postponed to the level of the metric entropy or the fat-shattering dimension. On the other hand, this impacts negatively the rate of convergence (dependency on m), an indication of the fact that optimizing the dependencies on the three basic parameters amounts to looking for a trade-off

Texto completoThe analysis of knowledge classification systems in Philosophy and Librarianship by a critical historical-conceptual point of view with an approach in the concepts of class, category and facet was developed from specific objectives to accompany and outline the path of knowledge (classes) and beings (categories) classification in relation to Philosophy; to investigate the possible influences that the philosophical classification historically exerted on traditional bibliographical classifications; and to verify in which way the specific concept of category, class and facet have been defined in the ambit of traditional librarianship classifications. This research is of exploratory-descriptive type, based upon pertinent literature, resulting from both areas of knowledge in discussion. From the studied bibliographical material, a theoretical reference was built, leading to objectivation, analysis, discussion and a profound study of the object. Its possible to affirm that even the principles of philosophical classifications in relation to knowledge and beings, as well as the classifications that divide knowledge and beings, are presented as constructs, purposed to understand and to train the information of beings and knowledge. The influence of philosophical classifications on bibliographical classification is settled by bibliographical classifications, which are adaptations of knowledge or science. The bibliographical ones, frequently utilize terms originated from philosophical that are modified and transformed into tools. In synthesis, it may be stated that, from Philosophy, absorbed in theoretical explanations, even Librarianship, worried with instrumental and application (pragmatic) solutions, the proposed plans of bibliographical classifications have been beneficiated from the approximation of this two areas of knowledge. The conceptual review in relation to notions of class, category and facet needs a better attention in design, planning and in the structuring of classification systems, as pointed out by experts on Classification, in the modification and specification of classification tables and also indexation languages, aiming its adequacy and significance. The resulting contributions, outlined by a functional-instrumental perspective, would help professionals to reconsider their systems of ideas and procedures in relation to construction and evaluation of indexation languages and regular classification of documents. The information science will be responsible to develop theory fundamentation of its application field, discussing critically its conceptual basis, with attention to the practices in use by Librarianship and Documentation in relation to terms and concepts. The study validates the hypothesis initially described, determining that the terminological consistency of terms as category, class or facet contribute to improve the operacionalization of knowledge processing in Information Science and that to category schemes it doesnt fit a neuter value, since that always favored a certain conception of the world, in which predominates its pragmatic nature As result of the investigation, some perspectives are presented, selecting questions of extreme relevancy and interest for future researches.

Texto completo2019 was a record year in transaction volume in Stockholm's commercial real estate market. A variety of investor categories were involved in transactions in Stockholm County. The locations where real estate investments are made are categorized by the municipality and its property type according to the location's attraction on a scale with AA, A, B, C, and D where AA is the most attractive location and D the least attractive location. An A-location in one municipality is not necessarily comparable with an A-location in another municipality, where the city in general has the most attractive locations. This has aroused interest in finding links between investor categories and the locations of real estate investments in Stockholm County as well as between Stockholm municipality and other municipalities in a comparison. As a deeper study, an analysis is carried out to explain how factors affecting real estate investment in an A-location can differ between different municipalities. Investments in A-locations are chosen to analyze since it no matter municipality is supposed to be an attractive location and A-locations have more available data than AA-locations. The method used to find links between investor categories and the locations of investments in Stockholm County, Stockholm Municipality, and its other municipalities has consisted of mapping and analyzing transaction data over Stockholm County 2019. To understand how factors affecting investments differ between A-locations in different municipalities in Stockholm County a survey based on the theory of investment influencing factors has been implemented. The transaction data shows a variation of investor categories in different locations, both in Stockholm municipality and other municipalities. Examples of what the data shows are that the most active investor categories in AA-locations were private real estate companies and “other investors”, and that the opportunistic real estate funds only were involved in transactions in B-locations in Stockholm municipality. The survey shows that there are some similarities in factors affecting the investments in industrial properties between municipalities. Investing in industrial properties in an A-location appears to be linked to all levels of the location: micro, neighborhood, and the attractiveness of the neighborhood. Furthermore, there was a general attitude that proximity to the highway and high technical standards were positive factors for investing in industrial property. Reasons for investing in a property for residential purposes appear to be strongly linked to how the detailed development plan in the area matches the investor's intention of buying the property, which in short-term doesn’t have anything with the location itself to do, but in the long term can affect the neighborhood. Other factors for investing in a property for residential purposes may be related to the neighborhood where community service and urban environment were considered attractive factors for a location. An interesting difference when it comes to real estate investments with housing development purposes is that the physical factors seem to have a lesser impact for the investor in Stockholm municipality, compared to Täby where the investor considered it very important.

Texto completoThe notion of plurilateral decision comes from a doctrine imported in France by Leon Duguit at the beginning of the 20th century. Of German origin, this doctrine consists in subsuming all the agreements under a meta-category called “plurilateral decision”, the contract of which is only a subcategory. Along with the unilateral decision, the plurilateral decision constitutes the summa divisio of legal acts. Like the unilateral decision, the plurilateral decision has several categorial subdivisions to wich distinct legal regimes are attached. Faced with the contractual crisis our legal order is going through and the multiplication of pseudo contracts, the concept of plurilateral decision represents a necessary stopgap. Modernized, it thus provides a classification of agreements able to clarify a subject presently faced to some disorder

Texto completoModel selection is of major interest in statistical learning. In this document, we introduce model selection methods for bi-class and multi-class support vector machines. We focus on quadratic loss machines, i.e., machines for which the empirical term of the objective function of the learning problem is a quadratic form. For SVMs, model selection consists in finding the optimal value of the regularization coefficient and choosing an appropriate kernel (or the values of its parameters). The proposed methods use path-following techniques in combination with new model selection criteria. This document is structured around three main contributions. The first one is a method performing model selection through the use of the regularization path for the l2-SVM. In this framework, we introduce new approximations of the generalization error. The second main contribution is the extension of the first one to the multi-category setting, more precisely the M-SVM². This study led us to derive a new M-SVM, the least squares M-SVM. Additionally, we present new model selection criteria for the M-SVM introduced by Lee, Lin and Wahba (and thus the M-SVM²). The third main contribution deals with the optimization of the values of the kernel parameters. Our method makes use of the principle of kernel-target alignment with centered kernels. It extends it through the introduction of a regularization term. Experimental validation of these methods was performed on classical benchmark data, toy data and real-world data

Doctoral thesis, Universitätsbibliothek Leipzig, 2011. http://nbn-resolving.de/urn:nbn:de:bsz:15-qucosa-77620.
Texto completoSince 2004 several illegal or aberrant transfers of animal by-products (ABP) from category 3 (according to Regulation (EC) No. 1774/2002: not intended for food production) back into food chain, have led to the political discussion, whether duty of material identifiability by separate storing of ABP on site and sole labeling of containers during transport are sufficient to protect consumers from ABP not intended for human consumption. To guarantee adequate utilisation of ABP from category 3, the German Federal Council claimed for an immediate and conclusive marking of ABP by dyeing or similar solutions. This study was implemented to define a convenient, registered feed additive for dyeing of slaughter by-products from category 3, which realize a feasible, from extraction to processing visually conclusive, long-lasting, traceable as well as sustainable and cost-effective marking on site to ensure traceability of intended utilisation as ABP from category 3 and to prevent their influx into food chain, without an impairment of the neutrality of products (e.g. pet food) made from marked ABP. For marking of slaughter by-products by air spraying device, registered colouring feed additives (Regulation (EC) No. 1831/2003) as well as diagnostically established fluorescence pigments were selected and investigated regarding their marking unambiguousness, colour retention after processing and visual neutrality in food and feed made from marked ABP by evaluation of five untrained judging persons in the course of a simply delineative, sensorial and impartial test (official list of analysis methods, ASU §35 LMBG, L 00.90-6), and by comparative RGB-colour measurement of images scanned from stained ABP samples. Detection of aberrant or deliberate discharge of marked ABP into food production was evaluated by investigation of thin layer chromatography (TLC), inductively coupled plasma optical emission spectrometry (ICP-OES), photometry and fluorescence spectrometry. Neutrality of marking feed additives in feedstuff was determined by a feeding preference test with nine dogs of the Beagle breed using pet food made from unmarked und marked ABP. Lissamine Green E142 (1,3 mg E142 per kg ABP) was selected as marker dye for slaughter by-products on site based on its unambiguousness of marking due to the significant different red-colour intensity compared to the non-marked ABP as well as the simultaneous neutrality of the colouring additive E142 in the final products feed and food. Colour retention of E142 marking was conclusive with regard to handling by washing, cold (8°C for two days) respectively fridge storage (-25°C for 14 days) and utilisation of a 14-, 90- and 150-days-stored marker solution. For marking, Lissamine Green was combined with the chemical detectable and registered food colour titanium dioxide (E171: 90 mg/kg ABP). The marker additives are classified as safe for humans and animals within the preferred concentrations for colouring ABP. With E142 und E171 marked ABP were traceable in food and feed using detection methods TLC (limit of detection: ≥7,5 µg E142 per kg sample), photometry and ICP-OES (limit of detection: ≥8,3 mg E171 per kg sample) at a proportion of 0,55% (TLC: E142) respectively 9% (ICP-OES: E171), whereas the named markers were not detectable in chemical and thermal extracted fats produced from marked high-fat ABP. Based on the visible and fluorescence spectrometric detectable autofluorescence of animal tissues as well as the uncharacteristic emission and absorption spectra of fluorescence pigments in processed ABP, fluorescence markers are not preferential for marking of slaughter by-products from category 3. Marking of slaughter by-products by air spraying device appeared practicable in due consideration of marker depletion and tissue-adapted marker per kg ABP. Current time of marking under laboratory conditions (5 sec. per kg ABP) must be graded as too long, regarding high transfer rates in slaughterhouses. Concerning the residue-free cleaning of stainless steel and even plastic surfaces from the marker solution, the utilisation of marked ABP for manufacturing of feed and technical products is unproblematic. Investigated pet food samples produced from marked ABP were from comparable commercial sensory product quality and showed no deviation of normal storability due to sterilisation. In conclusion, with E142 and E171 visible marked ABP from category 3 are suitable as crude materials for pet food production. The application of the combined marker solution (E142 and E171) have to be evaluated as comparative expensive (33 Euro per ton ABP), while the exclusive application of E142 as the optic conclusive and sensitive detectable marker for ABP is associated with sustainable costs from 1,70 to 3,40 Euro per ton ABP. To date, an EU-common regulatory framework for marking of ABP from category 3 could not be specified. Nevertheless the political discussion is still continued, especially in Germany

The second article complements the examination of the psychometric properties. It contributes evidence to the predictive validity of indirect self-esteem measures. With using non-self-reported criteria, a double dissociation between explicit and implicit self-esteem is tested. The third article brings into focus an applied aspect of personality psychology. It is analyzed how defensive reactions are related to self-esteem discrepancies, that are different combinations of explicit and implicit self-esteem

The news classification problem is concerned with how to assign the correct category for the unclassified news. Although a large number of past studies have studied this problem, a common weakness of these studied is that their classification algorithms were usually designed from technical perspective and they seldom considered how experts really classify the news in a practical classification process. In this research, we first observe how media workers classify news in their daily operations, and we find that their classification process mainly consists of the following operations. (1) If some important keywords or phrases are present in the news, then they directly assign the news to certain categories. (2) Otherwise, they must check in details the whole content of news to determine which category it should belong to. (3) Since a news category may contain several independent but related subcategories, the news is usually classified by assigning it to the most appropriate subcategory, which can in turn determine its category. By imitating the above working process, we proposed a news classification algorithm. In the learning phase, we use associative classification rules to find representative keywords in each category. In addition, we further generate a number of subcategories by clustering news under each category. In the classification phase, we assign unclassified news the most appropriate category by using associative classification rules if rules’ confidence is high enough. Otherwise, we will determine the category by measuring the similarity between unclassified news and subcategories. The experimental comparison shows that our approach has better and more stable classification performance than traditional algorithms.

In recent years, researches of aspect-category-based sentiment analysis have been approached in terms of predefined categories. In this paper, we target two sub-tasks of SemEval-2014 Task 4 dedicated to aspect-based sentiment analysis: detecting aspect category and aspect category polarity. Also, a pre-identified set of aspect categories {food, price, service, ambience, miscellaneous} defined by SemEval-2014 have been used in this paper. The majority of the submissions worked on these two sub-tasks with machine learning mainly with n-grams and sentiment lexicon features. The difficulty for these submissions is that some opinion word (e.g., "good") is general and cannot be referred to any particular category. By contrast, we use aspect-opinion pairs as one of the features in this paper to overcome this difficulty. To detect these pairs, we identify the opinion words in customer reviews, and then detect their related aspect terms by dependency rule. This system has been done on restaurant domain applying to Chinese customer reviews. Our experiment achieved 87.5% of accuracy by using Word2Vec to detect aspect category polarity. Aspect-opinion pair features employed in this system contribute to 88.3% of accuracy. When all features are employed, the accuracy is improved from 84.4% to 89.0%. Experimental results demonstrate the effectiveness of aspect-opinion pair features applied to the aspect-category-based sentiment classification system.

Rapid and vigorous development of information network technology has resulted in the largest data repository. Collecting relevant information in such a large body of data is rather difficult for any user. This paper is aimed to help users to grasp key information in a short period of time. We observe that term frequency in a article can be used as keyword for that article. Article theme can be easily grasped based on these keywords. Therefore, users can find the information they want through keyword and significantly reduce unnecessary search time. Proper word segmentation enables article theme extraction. And article classification can be achieved by theme differentiation. We use 320 articles in the theme classification experiment. These articles are divided into two categories: training and testing. There are 285 training samples, all belonging to the sports news theme. There are 15 testing samples that are consists of themes picked at random. The result is able to pick out 6 articles which belonging to sport news theme among the 15 testing samples. Among the 20 negative samples, there are 4 false positives, all due to names related to sports events.

“Directory style” is the most common website data mode. Take shopping websites, for example; classifying products by catalogue can promote the efficiency of product data processing. The problem of product matching is one of very fundamental problems of the website data processing and the purpose of the product classification is to find out which products are belonged to the same kind of products from two websites. Products which are under the related category are possible to be the same kind of products because of product between two websites. Hence, finding out the similarity of the category between websites can elevate the accuracy and efficiency of product matching. This thesis comes up with a kind of improvement method about the categorical correspondence. The traditional VSM (Vector Space Model) can not compare the similarity of two websites accurately. This is because product amount is too few or the product title is inconsistent under the category and will make the similarity of categories be totally different from VSM (Vector Space Model). In order to improve this problem, the thesis proposes a concept of Middle Category which is a catalogue website has general characteristics. Through categorical matching with Middle Category, the accuracy of categorical matching of other websites will increase. This thesis discusses characteristics which are necessary for being Middle Category. In addition, the thesis also proves that similarity of categories will increase by the information of Middle Category. The result of the thesis’ experiment manifests that after categories of websites do the similarity matching by Middle Category; the same categories utilize LMCS (Longest and Most Common Segments) to do product matching that increases recall, precision, and similarity over eighty eight percent.

Data mining can use the information and pattern that hidden at the data, they can Classification, prediction, clustering and association. Formal Concept Analysis (FCA) is a data analysis method that found the structure of the theoretical concepts from the data set, it can be formalized into this article tabular graphical concept lattice, and applied on the data’s classification. This study applies the Formal Concept Analysis to classificate the data set of the categorical-type and multivariate attribute. Since the time complexity of FCA in the worst case achieve O(2N) (N is the number of nodess), and the node number is affected by the object number and attribute number. Therefore, this study use record reduction to decrease the object number and use dimension reduction to decrease the attribute number, so that the original high time complexity data set can be classificated, and use system experiments to evaluate the effectiveness. Experimental results show that when using record reduction, the max usable record number (object number) is affected by the attributes number, and their correlation is negative;When using dimensions reduction, the max usable attribute is affected by object number, and their correlation is negative. When data set be processed by record reduction, the data record number will affect the classification rate, and their correlation is positive;When data set be processed by dimensions record reduc, the data attribute number will affect the classification rate, and their correlation is positive. Futhermmore, the dimensions reduction method is better than record reduction method in the classification rate.

Successful products are the foundation of any successful business, and the added sales may ensure the sustainability of a company, so product design and development is the foundation of any successful business. A consumer purchase products for their added functional and psychological values, thus the product design must take consumers’ emotional needs into consideration; the products’ added value also comes from innovation, thus the designers cannot afford being limited by their personal knowledge and experiences. Quick to market at reduced time and cost is the Nirvana of product design. This research combines Kansei Engineering and the Knowledge Effects to propose a Structured Innovative Product Design Process. Specifically, the category classification of Kansei Engineering is applied to ensure the proper extraction of consumer emotional needs, and Knowledge Effects database of TRIZ is applied to enhance the designer’s efficiency and effectiveness in converting these needs to design concepts. The applicability and operability of this proposed design process was tested in this research using graduate students enrolled in Ming Chi University of Technology’s Industrial Design Department as well as an experienced practitioner (also an MCUT alumnus). The results indicate that (1) all participants were able to develop satisfactory design concepts using the proposed design process without major difficulty; (2) the effects solutions generated with the help of Knowledge Effects database were rich in variety, which did help designers expand their horizon; (3) participants could easily follow the proposed design process without specific background in TRIZ or Kansei Engineering; and (4) the general-purpose path map developed by the researcher could help further streamline the process.

Texto completoAtualmente, os Sistemas de Recomendação têm apresentado um aumento na sua utilização, uma vez que permitem uma melhor entrega de um serviço aos seus utilizadores. No entanto, de forma a que estes sistemas consigam ser robustos e eficientes, é necessária a existência de uma base de conteúdo corretamente classificado. No caso de classificação de programas de televisão, a sua classificação pode, para além de melhorar o conteúdo mostrado no Guia de Programas Eletrónicos, melhorar a base de dados utilizada para os Sistemas de Recomendação e consequentemente o sistema que faz uso desses dados. De forma a automatizar o processo, o Processamento de Linguagem Natural surge como um conjunto de técnicas muito útil, uma vez que permite às máquinas entender e processar linguagem natural, assim como classificar grandes quantidades de dados automaticamente. Este documento, elaborado em contexto de Dissertação para obtenção de Mestrado e estágio na empresa Altice Labs em articulação com a Altice/MEO, apresenta o processo de desenvolvimento de um modelo capaz de classificar programas de televisão pela sua categoria, com base no texto da sua sinopse, utilizando técnicas de Processamento de Linguagem Natural. Começamos por discutir o contexto teórico de alguns conceitos importantes para o problema, seguindo-se uma revisão a trabalhos semelhantes de forma aperceber as técnicas tipicamente implementadas e resultados obtidos. Seguidamente, são apresentadas, com detalhe, as tarefas desenvolvidas e decisões tomadas no contexto desta investigação/estágio, às quais acresce uma explicação de como o produto final está a ser integrado nos sistemas da MEO para ser utilizado diretamente nas suas bases de dados. O desenvolvimento de um modelo inteligente para classificação de programas permite à Altice/MEO a automatização dos seus processos de classificação e um consequente melhoramento do conteúdo apresentado no Guia de Programas Eletrónicos (EPG) e nos Sistemas de Recomendação que fazem uso dessa classificação, assim como ajudará também a indicar oportunidades de negócio ao melhorar o detalhe no perfil dos clientes.
Currently, the Recommendation Systems have shown an increase in their use, since they allow better delivery of a service to its users. However, for these systems to be robust and efficient, a correctly classified content base is required. In the case of television program classification, its classification can, besides improving the content shown in the Electronic Program Guide, improve the database used for the Recommendation Systems and consequently the system that makes use of this data. To automate the process, Natural Language Processing appears as a very useful set of techniques, since it allows machines to understand and process natural language, as well as classify large amounts of data automatically. This document, elaborated in the context of a Dissertation to obtain a Master’s degree and internship at the company Altice Labs in articulation with Altice/MEO, presents the process of developing a model capable of classifying television programs by their category, based on the text of their synopsis, using Natural Language Processing techniques. We start by discussing the theoretical context of some important concepts for the problem, followed by a review of similar works to understand the techniques typically implemented and associated results. Next, we present, in detail, the tasks developed and the decision path in the context of this research/internship, as well as how the final product is being integrated into the MEO systems to be used directly on their database. The development of an intelligent model for program classification allows Altice/MEO to automate its classification processes and results in a consequent improvement of both the content presented in the Electronic Program Guide (EPG) and the Recommendation Systems that make use of that classification, as well as helping indicate business opportunities by improving the detail on the client’s profile.

Amount and position of defects on TFT-LCD panel affects the level of the panel, adding Automatic optical inspection(AOI) into the light-on test, which can automatically detect defects from the image of LCD panel. This study constructed a model based on Convolutional neural network of deep learning, which can classify various kind of defects at once. Without any pre-processing, the model can automatically capture features through a large number of data and model training, resulting in a high-efficiency and high-accuracy defects classification model. This study used actual panel images from Taiwan's leading computer hardware manufacturers for model construction, model testing and validating the result. After validation, the model constructed by this study has 99.9% model accuracy and excellent specificity and sensitivity, the model can also finish the process of classifying a TFT-LCD panel in only 467 seconds.

Texto completoOs nódulos tiroideus são uma entidade comum, sendo a sua maioria benignos. As neoplasias malignas da tiróide apresentam-se, contudo, como nódulos em 95% dos casos. A citologia aspirativa por agulha fina é fundamental para o estudo dos nódulos tiroideus, pois reduz cirurgias nos pacientes com lesões benignas e tria adequadamente pacientes com nódulos malignos ou potencialmente malignos para intervenção cirúrgica. A nomenclatura de Bethesda é uma proposta internacional de classificação dos achados citopatológicos. Uma das suas categorias, a “lesão folicular de significado indeterminado” é utilizada quando os achados citomorfológicos não são nem convincentemente benignos nem suficientes para uma interpretação de malignidade. Nódulos com esta classificação revelam-se um desafio em termos de manejo clínico. Vários estudos têm sido feitos para determinar que patologias estão na origem de uma lesão folicular de significado indeterminado. Neste estudo é feita uma correlação cito-histológica dos casos de lesão folicular de significado indeterminado submetidos a cirurgia, utilizando dados do Instituto Português de Oncologia Francisco Gentil de Lisboa, do Hospital da Luz e do Hospital Beatriz Ângelo. Os hospitais consultados tinham 5267 relatórios de citologias tiroideias entre 1 de Janeiro de 2012 e 31 de Dezembro de 2013 e 310 foram de classificados como “lesão folicular de significado indeterminado”. Cento e um casos foram submetidos a cirurgia e o relatório anátomo-patológico foi consultado. Cada diagnóstico histológico foi anotado individualmente e como muitos casos tinham mais do que uma patologia um único diagnóstico dominante foi considerado para o estudo estatístico. Quatro grupos foram criados de acordo com um diagnóstico dominante: neoplasia maligna, neoplasia benigna, inflamação e hiperplasia. Um quinto grupo foi criado para doenças com potencial maligno incerto e para micro carcinomas. Uma vez que a inflamação pode ser um estímulo para a malignidade, todos diagnóstico histológico associados a inflamação foram inventariados. As neoplasias malignas foram o diagnóstico dominante em 28 casos, correspondendo a 27.72% de todos os casos. As neoplasias benignas foram o diagnóstico dominante em 25 casos e a inflamação em 10 dos casos. A hiperplasia foi considerada como diagnóstico dominante em 30 dos casos, sendo este o maior grupo. Os micro carcinomas e os tumores com potencial maligno incerto perfizeram 8 casos no total. A inflamação estava presente em 22 casos. Na população estudada revelou-se que a maioria dos casos de lesão folicular de significado indeterminado tinham o diagnóstico histológico de hiperplasia. As neoplasias malignas tiveram uma frequência de 27.72%, maior que o esperado. O total de casos de neoplasias benignas e malignas corresponderam a mais de metade de todos os casos e a citologia aspirativa de agulha fina deveria ter triado adequadamente estes casos.

The Impact Factor (IF) ranking of journals in Journal Citation Reports (JCR) influences journal’s academic evaluation and the IF ranking is close related to its journal category. Therefore, I put this research into the perspective of academic evaluation to analyze the 88 “Information Science and Library Science” (IS&LS) journals that are included in JCR to explore the category problem of JCR through bibliometrics. I analyze the citations and author’s institutions of the four different sub-categories, “LS” (Library Science)、”IS” (Information Science)、”SM” (Scientometrics) and “MIS” (Management Information System), and four specific journals (LISR、JASIST、SMs、MISQ), also examine the Impact Factor and Quartile distribution of these journals. As for discipline of citation, my research shows that the articles in IS&LS、LS、IS and SM mostly cite the literature from the LIS, except articles in MIS. Articles in LS, IS and SM cite the literature in LIS, computer science, general science and medicine most, while the articles in MIS most cite the literature from computer science, MIS, management and business. It worth mentioned that the citation disciplines between LIS and MIS are not very close. As for citation in specific journal, LISR, JASIST and SMs are mostly citing and cited by journals in LIS and are least by journals in MIS. MISQ is mostly citing and cited by journals in computer science and business, has no cross citation with journals in LIS, which means the selected journal between MIS and LIS have few cross citations. As for the author’s institutions, authors in IS&LS, LIS journals are mostly based in LIS institutions; authors in MIS basically come from business school and MIS, few come from LIS. It is obvious that the authors in MIS and LIS journals do not come from the similar discipline institutions. The authors in selected journals also show the similar feature. The authors in my selected journal of LIS are from LIS; authors in MISQ are mostly from business school, MIS and management, very few come from LIS. My research finds that the citation discipline and author’s institution discipline of journals in four subcategories are with high heterogeneity in MIS and LIS (LS, IS, SM). MIS is inclined to transdisciplinary and has faster development than LIS. The IF is significantly different between MIS and LIS. The Q value of MIS falls in Q1, while the Q value of LS mostly falls in Q4. LIS though leads in numbers of journals, articles, and authors but the average numbers of citation per article are far behind the MIS, which means the difference between LIS and MIS falls not only in citation discipline and author background but also in citation behaviors. According to the citation analysis in this research, my finding shows that IS&LS and LIS are statically significant in citation discipline and author’s institutions. However, MIS and LIS have significant difference in citation discipline, author institutions and IF. As we can see, the top 25% in journal ranking are mostly occupied by MIS journals, which might have negative impact on the IF ranking and academic evaluation of the LIS journals and authors. Besides, LIS journals seldom cite the MIS journals, and articles in MIS almost don’t cite articles in LIS Journals. The authors in MIS and LIS journals mostly come from institutions in different disciplines. To conclude, the journals in MIS and LIS are heterogeneous.
