Full textBen, Nasr Sana. "Mining and modeling variability from natural language documents : two case studies." Thesis, Rennes 1, 2016. http://www.theses.fr/2016REN1S013/document.
Full textDomain analysis is the process of analyzing a family of products to identify their common and variable features. This process is generally carried out by experts on the basis of existing informal documentation. When performed manually, this activity is both time-consuming and error-prone. In this thesis, our general contribution is to address mining and modeling variability from informal documentation. We adopt Natural Language Processing (NLP) and data mining techniques to identify features, commonalities, differences and features dependencies among related products. We investigate the applicability of this idea by instantiating it in two different contexts: (1) reverse engineering Feature Models (FMs) from regulatory requirements in nuclear domain and (2) synthesizing Product Comparison Matrices (PCMs) from informal product descriptions. In the first case study, we adopt NLP and data mining techniques based on semantic analysis, requirements clustering and association rules to assist experts when constructing feature models from these regulations. The evaluation shows that our approach is able to retrieve 69% of correct clusters without any user intervention. Moreover, features dependencies show a high predictive capacity: 95% of the mandatory relationships and 60% of optional relationships are found, and the totality of requires and exclude relationships are extracted. In the second case study, our proposed approach relies on contrastive analysis technology to mine domain specific terms from text, information extraction, terms clustering and information clustering. Overall, our empirical study shows that the resulting PCMs are compact and exhibit numerous quantitative and comparable information. The user study shows that our automatic approach retrieves 43% of correct features and 68% of correct values in one step and without any user intervention. We show that there is a potential to complement or even refine technical information of products. The main lesson learnt from the two case studies is that the exploitability and the extraction of variability knowledge depend on the context, the nature of variability and the nature of text

"Big Data" is in vogue, and the explosion of urban sensors, mobile phone traces, and other windows onto urban activities has generated much hype about the advent of a new 'urban science.' However, translating such Big Data into a planning-relevant understanding of activity patterns and travel behavior presents a number of obstacles. This dissertation examines some of these obstacles and develops data processing pipelines and urban activity modeling techniques that can complement traditional travel surveys and facilitate the development of richer models of activity patterns and land use-transportation interactions. This study develops methods and tests their usefulness by using Singapore metropolitan area as an example, and employing data mining and statistical learning methods to distill useful spatiotemporal information on human activities by people and by place from traditional travel survey data, semantically enriched GIS data, massive and passive call detail records (CDR) data, and Wi-Fi augmented mobile positioning data. I illustrate that regularity and heterogeneity exist in individuals' daily activity patterns in the metropolitan area. I test the hypothesis that by characterizing and clustering individuals' activity profiles, and incorporating them into household decision choice models, we can characterize household lifestyles in ways that enhance our understanding and enable us to predict important decision-making processes within the urban system. I also demonstrate ways of integrating Big Data with traditional data sources in order to identify human mobility patterns, urban structures, and semantic themes of places reflected by human activities. Finally, I discuss how the enriched understanding about cities, human mobility, activity, and behavior choices derived from Big Data can make a difference in land use planning, urban growth management, and transportation policies.

Full textMetadata is the important information describing geographical data resources and their key elements. It is used to guarantee the availability and accessibility of the data. ISO 19115 is a metadata standard for geographical information, making the geographical metadata shareable, retrievable, and understandable at the global level. In order to cope with the massive, high-dimensional and high-diversity nature of geographical data, data mining is an applicable method to discover the metadata.
This thesis develops and evaluates an automated mining method for extracting metadata from the data environment on the Local Area Network at the National Land Survey of Sweden (NLS). These metadata are prepared and provided across Europe according to the metadata implementing rules for the Infrastructure for Spatial Information in Europe (INSPIRE). The metadata elements are defined according to the numerical formats of four different data entities: document data, time-series data, webpage data, and spatial data. For evaluating the method for further improvement, a few attributes and corresponding metadata of geographical data files are extracted automatically as metadata record in testing, and arranged in database. Based on the extracted metadata schema, a retrieving functionality is used to find the file containing the keyword of metadata user input. In general, the average success rate of metadata extraction and retrieval is 90.0%.
The mining engine is developed in C# programming language on top of the database using SQL Server 2005. Lucene.net is also integrated with Visual Studio 2005 to build an indexing framework for extracting and accessing metadata in database.

In recent years, the rapid development of computer technology and information industry has led to a significant increase in the amount of data. However, regarding these large and messy multidimensional data sets, we cannot quickly and effectively find the information that we need. Therefore, we have to use the data mining techniques to concentrate on extracting the information that we need from the data. In this thesis, we will introduce a relatively new data mining software, Rapidminer. We compare the Rapidminer with other data mining software via comparative analysis of a functional operating procedures. Through the application of four case studies including linear regression, neural networks, decision trees, and support vector machines to illustrate the operations of Rapidminer. There are two reasons to use Rapidminer in this thesis. The first one is that it has a very convenient graphical interface. The second one is that user does not need to learn other programming syntax, just need to select components and setting parameters. The display of analysis results is also diversification, which allowing users to choose the functional map to view the results.

The major objective of this study is to use self-organizing maps (SOM) and K-means method to cluster the consumers of E-Life Mall Corporation and Kuo-Kuang Motor Transport Company into appropriate categories. The service items concerned in this study fall into the first and fourth quadrants of the IPA matrix when Kano model is applied. This study uses data mining techniques to extract effective customer clusters, understand the differences among different clusters by Kano two-dimensional model, and analyze the importance and priority of clusters. The results of this study can be offered to the companies to design different marketing strategies by understanding and then improving the competitive advantages and weaknesses of service quality characteristics. Compared with market segmentation results by ANOVA, the service quality attributes of E-Life Mall Company consumers are classified into five clusters, key success factors of E-Life Mall Company consumers are classified into three clusters by K-means method. In addition, Kuo-Kuang Motor Transport Company consumers are classified into four clusters by K-means method. Moreover, the consumers are classified into two clusters by using complete linkage and Ward linkage methods. Finally, by integrating SOM and K-means, the consumers are classified into twelve clusters. According to four consumer categories proposed by Reinartz and Kumar (2002), twelve clusters are reduced to four categories. Then, this study analyzes Kano quality attributes,customers’demographic information, and average satisfaction based on these four categories. Different results generated by ANOVA, K-Means, and an integrated approach of SOM and K-Means methods are compared and discussed. The results of this study can provide insights for E-Life Mall Corporation and Kuo-Kuang Motor Transport Company to find appropriate customer clustering method.

This research made use of the outpatient data of pediatrics, and was divided into three main subjects to debate. (1) Because of different training background for each doctor, so there were some cognitive differences to using frequency of the same medicine, therefore, will the frequency of the patient''s medicine usage affect the rate of their future revisit examination? (2) To discuss the relationship between medical allowances of patients and their actions of see a doctor─will patient change their choice of medical treatment level, that when medical copayment be raise up? (3) Comparing the diagnostic differences between clinic pediatrician and emergency pediatrician, as well as their patterns of usage in medical resources. The results of research show that: (1) The result of Data-Mining found that; the frequency of the patient''s medicine usage has no absolute relationship with their situation of revisit, perhaps, this is relating to personal physique, conditions of external environment, or complications caused to other disease. (2) When patient go to a doctor, the expense is not necessarily the most important consideration, the confidence to doctor, or far and near distance…etc all are considerations. (3) After July 2001, patients paid the expense for tested-check items was displayed raise up, it is show that emergency pediatrician use tested-check items to assist diagnosis have higher proportion than clinic pediatrician. In order to understand the situation of usage in medical resources, this study was directed to three main subjects, and analyzed by Data-Mining and statistical methods, and provide the result to hospital and medical-related staffs as a reference.

This study aims to develop a data mining framework to analyze key factors of unemployment duration and the complex relationships among each factor. Conducted on the basis of real data collected from a representative Human Resource Agency in Taiwan. In order to extract latent knowledge and patterns from huge data about job seekers. This study formulates research hypotheses based on literature review, domain expert knowledge and supported by Bayesian Network, statistical test and correlation coefficient to screen out 15 key factors of the job seekers’ “general information, job requirement, education, working experience and new work category” have a significant effect on unemployment duration. Then, using Bayesian network to clarify the relationships among each factor and unemployment duration. Finally, this study presents a process of case studies that can extract the useful knowledge of data mining results efficiently. Major findings indicate that unemployment duration difference among each field, the employment tendency of different type of job seekers and job transition patterns in the current domestic labor market. For example, in a particular industry, workers with 3 to 6 years’ seniority may have a high turnover intention, the reemployment difficulty among middle aged workers, the regional wage gaps and other social issues. The results assist various types of job seekers obtain comprehensive information to find their own niche in the labor market. In the meantime, this study also provides the decision-making reference for government and enterprise. On the other hand, Human Resource Agency can base on the results to improve their services. Help job seekers to find the most favorable direction.

Professional baseball games emphasize data collection and analysis because each game provides plenty of data that needs to be analyzed. Data mining methods involve computer analysis techniques with which a crucial outcome can be found from a huge amount of data. The data mining techniques thus can be used to efficiently analyze the data of professional baseball and also avoid the mistakes often caused by manual analysis. This study aims to predict the outcome and scores of professional baseball games in MLB. The data of the study are all the regular season games from 2000 to 2012 of thirty teams in MLB. The variables are the average statistics of both the fielders’ and the pitchers’ performances in the last ten games. First, we used the Pearson product-moment correlation coefficient to delete the unrelated variables and variables of multicollinearity and to select the suitable variables. Then we applied the Back Propagation Network (BPN) of the artificial neural network to build a model for the selected variables. The first 100 games served as the training set of the model while the later 62 games as the validation set. After obtaining the predicted scores of each game, we compared them to the real outcome of the games and the money line. After using the output model to predict the scores of the host and the guest, we further compared them with the real outcome, run line, and money line of sports gambling. The experimental results have proven that the model of this study provided better prediction accuracy. Follow-up researchers may consider using different variables for the model to improve the accuracy of the predictions.

Support vector machine (SVM), rough set theory (RST) and decision tree (DT) are methodologies applied to various data mining problems, especially for classification prediction tasks. Studies have shown the ability of RST for feature selection while SVM and DT are significantly on their predictive power. This research aims to integrate the advantages of SVM, RST and DT approaches to develop a hybrid framework to enhance the quality of class prediction as well as rule generation. In addition to build up a classification model with acceptable accuracy, the capability to explain and explore how the decision made with simple, understandable and useful rules is a critical issue for human resource management. DT and RST can generate such rules, however, SVM can not offer such function. The major concept consists of four main stages. The first stage is to select most important attributes. RST is applied to eliminate the redundant and irrelative attributes without loss of any information about classification. The second stage is to reduce noisy objects, which can be accomplished by cross validation through using SVM. If the new data set would induce data imbalance problem, the rules generated by RST would be used to adjust the class distribution (stage 3). Through the stages described above, a data set with fewer dimensions and higher degree of purity could be screened out with similar class distribution and is used to generate rules by using DT which complete the last stage. In addition, the decisions concern with personnel selection prediction always involve handling data with highly dimensions, uncertainty and complexity, which cause traditional statistical methods suffering from low power of test. For validation, real cases of personnel selection of two high-tech companies containing direct and indirect labors in Hsinchu, Taiwan are studied using the proposed hybrid data mining framework. Implementation results show that the proposed approach is effective and has a better performance than that of traditional SVM, RST and DT.

Due to the rapid advance of information technology, data saving is not so difficult as before. The amount of data in the world, in our lives,keeps on increasing continuously. Data mining is developed to search for useful information from data. Undoubtedly, there also exists a lot of data in construction engineering. We try to use different data mining techniques to find out useful information from these data. During the process of steel structure design, a huge amount of data is developed at stress re-analysis stage. The main purpose of this study is to establish stress approximation models by using approximation methodology, one commonly used data mining tool. These approximation models can be used to replace full analysis during the time-consuming re-analysis process. Because stress data of steel structure is spatial correlated, we use a spatial data mining technique, Kriging methods, which is a spatial correlated approximation method. Several cases were used to test the Kriging-based models.Other approximation models, such as response surface methods(RSM),were also used to evaluate the performances of approximation models. The experiments depict that Kriging-based approximation models outperform other approximation models.

In recent years, due to the vigorous developments of database technology and artificial intelligence, data mining has become a useful and important technique in the area of information science. Data mining is a technique which can extract the hidden information from a large data base. It can help the researcher to search useful information that might be ignored and missed. Neural network has been used in the research of data mining since its powerful learning and adaptive capabilities. Through the learning process, the unknown information hidden in the data could be obtained by neural network. In this research, a new computation method based on the weights of the well-trained neural network is developed. By using the method developed, the degree of influence of each input variable to the output could be found and the useful influencing inputs also could be determined. Thus, the data mining of NN technique in data mining becomes very promising.

For a leading electronic component provider, to pursue high quality products is always one of the most serious issues to consider. Without maintaining high quality goods, its market shares could be grabbed and therefore replaced by rivals through reducing prices easily. This research adopt the RFM model provided by Hughes(1994)to analyze RMA data. In order to make the model adaptive to RMA applications, the new factor – prduct unit price has been added to evaluate the importance of these returned materials. Next, in order to rank the importance of these four factors, the AHP (Analytic Hierarchy Process, Thomas L. Saaty, in the 1971) method is used to determine their weights. Finally, the K-means cluster algorithm divides returned materials into groups., Based on the data analysis processes stated above, our main results would include two directions. The first one is four main RMA clusters are proposed, characterized and analyzed. The other contribution is to propose adequate RMA handling strategies for helping FAEs, product administrator, factory quality manager control and further enhance respective RMA goods.

This study aimed to develop a web-based data acquisition tool for data mining studies of drug therapies inspired by a 2004 study. To combine two predominant techniques, WWW and data mining are the bases of this study. Computer programming languages such as HTML, PHP, MySQL and JavaScript were used to develop the framework and the interaction between the project managers and this tool. EasyPHP was installed on a workstation PC, and was used to set up the client/server with PHP, MySQL, and Apache servers. A Linux PC with OS Fedora Core 4 was installed and served as a remote server for this tool. The Linux PC also served as a web server which allowed experts to log in to complete a project. Exported Weka ARFF file is the final step of this project, which enables project managers to apply Weka to data mining analysis. We successfully reproduced a 2004 study with this tool, including the questionnaires (simulated and generated) and the on-line expert log-in website (collect experts’ decisions and opinions). Moreover, it may shorten the time taken to construct a project using this tool. It may allow the project managers to define a project on their own demand. The project managers no longer need to manually build a project but can use this integrated and web-based tool to quickly complete a setup for a research project.

Family-based association tests are widely used in gene mapping. Pedigree disequilibrium test (PDT) is one of these tests for analysis of pedigree data. PDT derived by combining transmission disequilibrium and allele difference. In this thesis, we tried to combine the information of odds ratio, similarity difference, transmission disequilibrium and allele difference. We use some existing combination procedures, such as Tippett, Fisher and inverse normal method to combine the four statistics information.

Data warehousing has become very popular among organizations seeking competitive advantage by getting strategic information fast and easy. For corporation-wide data, high-sounding goals, and grandiose schemes, it turns into projects typified by massive cost overruns and mediocre results. The departmental Decision Support System (DSS) databases are called data mart that has an architectural foundation of a data warehouse. The data mart meets departmental decision making requirements and supports multiple dimensional data analysis situations.In the telecommunications industry, Call Detail Records (CDRs) contain a gold mine of information about customers and competitors. Traditional approaches were CDR-based only. The CDRs show subscriber trends. But a customer may own more than one subscriber line, and the line may belong to different customer at different period. In this paper, we built a data mart system based on the CDRs and the business vocation of customer. Using this data mart system, we can analyze the customer call behavior, and bring the behavior pattern to customer caring, pricing, marketing, and decision-making.

Retailing industry has grown to maturity stage. Due to the dense spreading of shopping centers, low distinction on merchandises among the stores, each department store is facing with very harsh competition. Today's customers have more choices and thus less loyalty. To adapt to the irreversible trend and strive to survive, and maximize the profit through the vast variety of customers, department store must recognize his strength in the market segments and find out those valuable 20% customers that contribute to 80% of the corporate revenue. All marketing strategy is aimed to attract new customers and retain these valuable customers. Stores use the purchasing records from credit cards and discounted membership cards to collect customers' purchasing behaviors. Inside the massive data, there are hidden rules that can be discovered through data mining. Store administrators can make the best use of them to adjust sales promotion strategy and improve corporate performance. In this article, we use RFM analysis, Recency of last patronage, Frequency of patronage, and Monetary value they spent, and data mining from the 3 periods purchasing records of an anonymous store to categorize customers' purchasing characteristics. We generates individual quantized R, F, M values as inputs, then through K-means cluster research, these RFM values are grouped into different clusters. Then we use MLE-WMLE algorithm to get each customer's monetary value trend. All analysises are based on 3 continuous years of data. Then we check whether the result from each year is stable. Then CART decision tree is used to classify customers as churn or retention in next year, then we uses Apriori algorithm to do "Basket analysis". Through association analysis between customers and merchandises, We propose a list of goods and services and the associated layout. Finally we compares customers of this store with the progressive average life of Taiwan residents to study why young customers are disappearing from this store. In this way new countermeasures are proposed to attract new customers and old customers are retained so that the store can survive the tough competition. All data are intentionally edited to protect the corporation in this study. We just tries to present a method to use data mining to assist administration.

Information for businesses or organizations, is a very important asset. Problems accumulated data, companies are facing, not a lack of information, but too much information. For the large and growing amount of data if not effectively treated, it will result in the case of so-called "data dumping" is. After statistical or use data mining techniques to be addressed, it can be converted into information or knowledge can be utilized. Available to decision makers to make the right moves. Enterprises are facing a huge market, competitive pressures, customer's consumption habits continue to change, the enterprise-based revenue sources and new customers and old customers repeat purchase consumption. The advancement of technology, the increasingly common use of the database, so that large amounts of data to be stored and managed to save. By data mining technology, and explore the establishment of consumer purchase signature rule merchandise mix, master Consumer consumption situation, the establishment of market segments and dividing the target customer base, and to identify potential market relevant consumers to predict their consumption behavior. The results pointed out that the turnover in the other Saturday with high turnover association, turnover in the other Sunday with high turnover relevance, do not turnover in the third quarter with high turnover relevance turnover not the shop on Sundays and public high turnover association, turnover in love do not shop on Sunday with high turnover association, turnover in other Zonta store on Sunday with high turnover relevance, not in turnover Feng Chia shop Saturday with high turnover relevance of the week in other public stores and Sunday have relevance, do week in stores and on Sunday there are fraternity association, the other week and Sunday Zonta store has relevance, do not store in the week and Saturday Fengjia have relevance.

It has been seen that the modern marketing paradigm has been rapidly shifting and business has used to apply target marketing to capture the right customers in promotion activity. However, the customer response model, regarded as the tool for targeting and prediction, is the most important task in marketing promotion. This research proposes a data mining (DM) based customer response model for insurance industry to help in finding unobvious but valuable promotion knowledge to support making marketing related decisions. First, we visited a leading insurance company (denoted by A), one of the most popular insurance companies in Taiwan, to frame the research focus. There were 188464 transaction records provided by A company. Of the collected data, two to third was used as a dataset being mined while the remainder as a test dataset. The ID3 mining algorithm was utilized to derive decision rules and obtained 943 qualified rules in total. The accuracy of the proposed model was 81%. To capture the important implication of the knowledge, the research analyzed the obtained rules in two directions including the level of supports and degree of conditions. The former focused mainly on the amount of supports and degree of conditions for the obtained rules to analyze the product categories with respect to the customer characteristics. The latter carried primarily out the relationships between different degree of condition and product categories. The research then conducted the second visit of A in order to validate the obtained knowledge in practice. The results indicated that the customer response model was able to aim at finding and diffusing the insurance marketing knowledge. It was also found that the proposed customer response model with the DM mechanism was decision-supportable based on the opinion of executive manager. Moreover, the proposed model would play a key role in changing the decision making style from experience-oriented to information-oriented. Other research findings were provided and managerial implications addressed in this research also.

Customer satisfaction is always the most important factor in cosmetics business. To keep and develop a long-term relationship with customers, a cosmetics vendor should not only provide a valuable product but also thoughtful service. Through customer relationship management (CRM), we can provide the right products and services at the right time with the right deliver channel to the right customers. In this research, we propose a method that utilizes an artificial neural network and a statistic cluster method to distinguish customers based on their purchasing behavior. With the method, different segment results can be generated for cosmetics vendors to target potential customers with the right promotional activities. Our experiment shows that cosmetics vendors are expected to increase profit significantly.
