Abstract (sommario):

Text-based conversational agents (CAs) are widely deployed across a number of daily tasks, including information retrieval. However, most existing agents follow a default design that disregards user needs and preferences, ultimately leading to a lack of usage and an unsatisfying user experience. To better understand how CAs can be designed in order to lead to effective system use, we deduced relevant design requirements from both literature and 13 user interviews. We built and tested a question-answering, text-based CA for an information retrieval task in an education scenario. Results from our experimental test with 41 students indicate that following a user-centered design has a significant positive effect on enjoyment and trust in a CA as opposed to deploying a default CA. If not designed with the user in mind, CAs are not necessarily more beneficial than traditional question-answering systems. Beyond practical implications for effective CA design, this paper points towards key challenges and potential research avenues when deploying social cues for CAs.

Abstract (sommario):

Purpose – The purpose of this paper is to develop a search engine dedicated to image retrieval in a bilingual (French and English) context. This paper presents the first phase of user testing that was carried out to validate and refine SINCERITY, the new search device. Design/methodology/approach – This first phase of the search engine testing involved a small group of image searchers (10 French-speaking and 10 English-speaking participants) who were asked to retrieve a sample of images (30) using the new tool. A questionnaire was also developed to compile the comments of the users. Findings – The results of this first phase of testing revealed that even though image indexing was sometimes problematic, the participants did not encounter major difficulties retrieving images with SINCERITY. Comments and suggestions received will be taken into consideration to improve the performance and aesthetics of the search engine. Originality/value – Once fully operational, SINCERITY will allow users to search images in an attractive and user-friendly manner. Eventually, other types of images (documentary and artistic) will be added to the image database linked to the image search engine, as well as other languages.

Abstract (sommario):

Background / Context A thorough understanding of the information-seeking behaviors of specific disciplines, as well as distinct user groups within a discipline, is fundamental to the process of development of disciplinary informatics. Significant research has been conducted, largely by library and information science scholars across a range of disciplines, but none that has focused primarily on education. Existing studies of information-seeking behavior have not been communicated to education scholars and professionals. The lack of consensus on the nature, execution, and application of educational research and the fundamental disconnect between scholars and practitioners further complicate the question. Users of education literature are diverse, including a spectrum of scholars, professionals, practitioners, parents, and the general public. Patterns of information seeking and application must be better understood to successfully develop a structure for education informatics. Purpose The purpose of this article is to bring to the education community a higher level of awareness of the overarching dynamics of information structure, organization, and retrieval, as well as recognition of the relationship of those dynamics to the evolving nature, definition, and execution of education research, to the development of education informatics. Research Design This article consists of a literature review and synthesis of research, analysis of distinct user populations, and an issues analysis with recommendations. Conclusions Exacerbated by failed communication opportunities across all segments of the producer/user community, and in spite of legislative mandates for data-driven and scientifically based research, there remains a void in the collective ability to converse across subsets of the user community and to translate research into practice. Practitioners need to learn basic research design, concepts, methodologies, and assessment measures; means to interpret results, validity, and bias; and ways to understanding limitations of the study. Practitioners also must be able to incorporate findings into their practice. They must do teacher research that is collaborative, replicable, shared, and reviewable and become both effective producers and critical consumers of research. Academic researchers need to focus on the complex issues that teachers face on a daily basis; explain why questions are being asked and conducted in a particular way; present findings in a manner more accessible to practitioners; and demonstrate how findings can be made generalizable. Education informatics has the potential to be the dynamic that helps translate research into practice to facilitate the application of research findings within the context of individualized environments, to provide the common ground for collaborative work, and to create the necessary synergy between theory and practice.

Abstract (sommario):

In less than a generation, the World Wide Web has grown from a relatively small cyber play-ground of academic "geeks" into an 11.5 billion-page collection of heterogeneous, inter-connected, network of information and collective knowledge. As an information environment the World Wide Web is informatically representative of all that is good and bad about the human need to both absorb and transmit knowledge. The 'open' nature of the Web makes instantly available to anyone who can "log-on", a boundless digital library of information, the quality of which cannot be enforced before, during, or even after its publication. Scrutiny of Information Quality (IQ), is therefore left up to those publishers conscientious enough to care about the quality of the information they produce and the users who choose to employ the Web as an information retrieval tool. The following thesis is a qualitative investigation of how the users of information make value-judgments about the information they encounter and retrieve from the Web. Specifically, it examines perceptions of IQ from the perspective of eighty "academic" high-end users, who regularly engage the Web and its search engines to search for and retrieve high-quality information related to their research, teaching and learning. The investigation has adopted an inductive approach in the qualitative analysis of quantitative ( 10,080 separate pieces of user-data) data in the context of such established frameworks as Davis' ( 1986, I 989) Technology Acceptance Model (TAM), and Wang & Strong's ( 1996) contextual IQ framework that conceptualised dimensions of quality into four IQ categories, namely: intrinsic; representational; contextual; and accessibility IQ. Through the detailed analysis of the driving theory behind these, and other associated models of: (I) user IT acceptance; (2) Information Seeking Behaviour (ISB}; and (3) multi–dimensional characteristics of IQ; the researcher has sought to find synergies and develop an innovative framework by which to explore the impact of users' attitudes, expectations and perceptions of IQ on their Web information retrieval behaviours. The findings associated with the thesis are consistent with the proposal of a new Ongoing Technology Acceptance Model (OTAM), which facilitates the measurement of users perception of the predictability of their technology interactions, and has the capacity to more accurately investigate user individual differences. Importantly, the OTAM allows the constructs of the original TAM, along with a new construct “Perception of Interaction" (Pol) to be used to investigate users ongoing use of technologies. Findings associated with user perceptions of information quality are also explored and discussed in relation to a proposed life-cycle model of IQ.

Abstract (sommario):

Two experiments were conducted to determine the feasibility of providing online command-selection aids to novice users of an information retrieval system. The results of the first experiment revealed a difference in the mean and variability of search performance between novice and expert computer users. Half of the novices were performing much like experts, while the rest of the sample was extremely slow. These slower novices were using inefficient scrolling strategies and appeared to be unfamiliar with the structure of the database. The second experiment evaluated whether novices could be assisted or trained with command-selection aids developed from the behavior of experts. The command-selection aids were defined in a 3 X 3 mixed factor design with type of model (frequency, sequence, or plan-based) as the between-subjects variable and dialogue initiative (user, computer, or mixed) as the within-subjects variable. The frequency and sequence models presented and ranked search procedures based on a command-usage profile and a command-transition matrix, respectively. The plan-based model presented an ordered set of search procedures with verbal explanations. All models were constructed for groups of homogeneous search problems selected by a sorting and cluster analysis. The three dialogue-initiatives determined whether the user, the computer, or both the user and computer controlled presentation of advice. Administration of the dialogue initiatives was completely counterbalanced and was followed by a final unaided transfer session. As a result of receiving online aiding, the wide ranging search performance of novice subjects was improved both during assistance and transfer. Performance of aided novices was superior to the slow novices and equal to the fast novices and experts. All three command-selection models were equally effective, with exception of the sequence model which sometimes presented frequent and complicated advice. Of the dialogues, mixed-initiated advice was ineffective during the first aiding session possibly due to the difficulties novices faced deciding whether to receive the suggested assistance. The conclusion of the study was that online command—selection aids can be effective if providing appropriate feedback and minimizing the amount of dialogue in aiding.

Abstract (sommario):

The research problem for this study is focused on the need to know how students acquire and use information. Research indicates a lack of understanding of what students know about information and how they use information and this study used the Information Literacy Competency Standards for Higher Education (Appendix A) as the basis for acquiring a better understanding of what kind of information freshman students at Virginia Tech need and how they acquire it during their first semester at college. Students were asked questions about their information use during fall semester 2000, using both email questioning and in face-to-face interviews. The data collected was used to develop insights into how students acquire and use information and resulted in suggestions that could be used in revising and improving instruction for freshman students that is provided by the University Libraries at Virginia Tech.

Abstract (sommario):

Thesis (MTech(Education)--Cape Technikon, Cape Town, 2001
This study presents a theoretical evaluative framework for information literacy initiatives. The evaluative framework is based on a holistic behavioural taxonomic approach incorporating affective, cognitive, and physical domains. In this study the behavioural taxonomic approach was applied to the evaluation of a historical information literacy initiative, the IFYE (Integrated First Year Experience), developed by the Cape T echnikon in 1997, South Africa. The motivating factor behind the evaluation was to determine whether it would be suitable as an implementable initiative at other institutions in the Western Cape. This coincided with the aims of Infolit, who had invited institutions of Higher Education to submit pilot projects on information literacy in a drive to promote information literacy throughout the Western Cape. Although the IFYE initiative may not have realised its full potential, information literacy has drawn continued interest and other initiatives have since been developed. Application of two eXlsttng taxonomles, demonstrated distinct limitations in their application and a new taxonomy was developed within the South African educational context. The new taxonomy was applied to the theoretical evaluation of an innovative elearning information literacy initiative developed by the Cape Technikon in 2000, which has been accepted by Infolit for wider implementation throughout the Western Cape. The final section of the study presents recommendations based on the evaluation of the elearning initiative, information literacy initiatives in general, and structural changes to the developed taxonomy. Areas for further research are also discussed.

Abstract (sommario):

There has been a long history of studying library users and their information seeking behaviors and activities. Researchers developed models to better understand these information seeking behaviors and activities of users. Most of these models were developed before the onset of the Internet. This research project studied faculty members' use of and their information seeking behaviors and activities on the Internet at Angelo State University, a Master's I institution. Using both a quantitative and qualitative methodology, differences were found between tenured and tenure-track faculty members on the perceived value of the Internet to meet their research and classroom information needs. Similar differences were also found among faculty members in the broad discipline areas of the humanities, social sciences, and sciences. Tenure-track faculty members reported a higher average Internet use per week than tenured faculty members. Based on in-depth, semi-structured interviews with seven tenured and seven tenure-track faculty members, an Internet Information Seeking Activities Model was developed to describe the information seeking activities on the Internet by faculty members at Angelo State University. The model consisted of four basic stages of activities: "Gathering," "Validating," "Linking" with a sub-stage of "Re-validating," and "Monitoring." There were two parallel stages included in the model. These parallel stages were "Communicating" and "Mentoring." The Internet Information Seeking Activities Model was compared to the behavioral model of information seeking by faculty members developed by Ellis. The Internet Model placed a greater emphasis on validating information retrieved from the Internet. Otherwise there were no other substantive changes to Ellis' model.

Abstract (sommario):

Handheld computers may hold the possibility for a one-to-one computer: student ratio. The impact of the use of Palm® (Palm, Inc.) handhelds on information acquisition and use by 5th grade students in a North Texas school during a class research project was investigated. Five research questions were examined using observation, interviews, surveys, and document analysis. Are there differences in information gathering and use with the Palm between gifted, dyslexic, and regular learners? What relevance criteria do students use to evaluate a web site to determine whether to download the site to the Palm and afterwards whether to use the downloaded site's information in the report? How do the Palms affect the writing process? Do the animations and concept maps produced on the Palm demonstrate understanding of the intended concepts? Are there significant differences in results (i.e., final products grade) between Palm users and non-Palm users? Three groups of learners in the class, gifted, dyslexic, and regular learners, participated in the study. The regular and dyslexic students reported using Web sites that had not been downloaded to the Palm. Students reported several factors used to decide whether to download Web sites, but the predominant deciding factor was the amount of information. The students used a combination of writing on paper and the Palm in the preparation of the report. Many students flipped between two programs, FreeWrite and Fling-It, finding information and then writing the facts into the report. The peer review process was more difficult with the Palm. Most students had more grammatical errors in this research report than in previous research projects. By creating animated drawings on the Palm handheld, the students demonstrated their understanding of the invention though sometimes the media or the student's drawing skills limited the quality of the final product. Creating the animations was motivational and addressed different learning styles than a written report alone. No statistically significant difference was found in the scores of the three 6+1 Traits categories, however the Palm users didn't meet the page-length requirement for the research project but the majority of the control class did.

Abstract (sommario):

The purpose of this study was to develop a consensus from a panel of experts composed of library deans/directors, reference librarians, and instructors with online teaching experience. The panel developed the methodology necessary for evaluating free sources of information on the Internet for inclusion in academic library holdings by the year 2010. The following areas were explored as they related to the forecast: 1) The changes in higher education institutions that will be necessary to prepare students to deal with free sources of information on the Internet; 2) The procedures that librarians need to develop and implement to ensure that free Internet materials will meet quality standards for inclusion in academic library holdings; and 3) The things that publishers of free sources of information on the Internet need to do to ensure that their materials will be considered for inclusion in academic library holdings. The Delphi panel was composed of 24 members: eight library deans/directors, eight reference librarians, and eight instructors with online teaching experience. The members of the panel were selected from the community colleges of the Tennessee Board of Regents System. In the first round of the study, panelists responded to 10 open-ended questions on an e-mail questionnaire dealing with free sources of information on the Internet. The narrative responses to the questions were specific and provided a basis on which to develop the Round 2 Questionnaire. In the second round of the Delphi study, panelists responded to 9 questions with 42 subparts. The results of this study may be used to project the information needs of students as well as suggest strategies for publishers on the basis of the data collected in this study. A major finding of the study was the need for reliable information in documents on the Internet. The Delphi panel also listed the lack of permanence of Internet sites as a major reason librarians do not use free sources of information on the Internet. The Delphi panel recommended that educators assist students in dealing with Internet materials by teaching them how to use critical thinking skills.

Abstract (sommario):

In this article the subject of Informing through user-centered Exploratory Search and Information Retrieval utilizing human-computer interaction strategies is analyzed. Exploratory Search is a new field that has sprung from the more general Information Retrieval. Informing Science is a trans-discipline which transcends a large variety of fields and seeks how to best inform all the clients of interest. One facet of Informing Science, the process of elucidating the best methods of informing inquiring clientele, is served by user-centered Exploratory Search and human-computer interaction strategies. This work explains a human factors method which allows the comparison of the performance of multiple IR systems and can enhance the comparative topic focused IR search quality. This human factors method also allows the human participants to provide their IR explicit feedback and record these judgments as a gold standard for future comparison. This human factors method is tested by established statistical analysis and allows the statistical comparison of the IR performance of a selection of IR systems.

Abstract (sommario):

On information markets, many suppliers and buyers of information goods exchange values. Some of these goods are data, whose value is created in buyer interactions with data sources. These interactions are enabled by data market services (DMS). DMS give access to one or several data sources. The major problems with the creation of information value in these contexts are (1) the quality of information retrievals and related queries, and (2) the complexity of matching information needs and supplies when different semantics are used by source systems and information buyers. This study reports about a prototype DMS (called CIRBA), which employs an ontology-based information retrieval system to solve semantic problems for a DMS. The DMS quality is tested in an experiment to assess its quality from a user perspective against a traditional data warehouse (with SQL) solution. The CIRBA solution gave substantially higher user satisfaction than the data warehouse alternative.

Abstract. In order to help people better understand the culture of the Republic of China (ROC), experience the cultural connotation of ROC, and facilitate the research by researchers and the inheritance of ROC culture, this article proposes a ROC textbook retrieval system. The system is mainly divided into four modules: login and registration, book retrieval, online reading, and document downloading. We summarized and classified existing ROC textbooks, and converted them into electronic materials by scanning to build a database of ROC textbooks. According to the characteristics of textbooks, a fast retrieval algorithm is proposed to provide users with book search, online reading and other functions on the client interface, enabling users to search and read ROC textbooks online at all times and places through electronic devices, accumulating cultural literacy. Users can also download books and documents according to their own needs.

Abstract (sommario):

Nowadays, the amount of information grows in an exponential way, mainly because of technological advances in media. This scenario claims for the development of different skills in order to increase learning abilities, making them personal and customizable. Such factor is significant in a changing society, which implies in a range of mechanisms which would allow to identify, in a non-intrusive way, which learning style some specific student would prefer to perform in order to build knowledge from some learning object under a learning context. This requires defining some strategies in order to recognize adult learner’s learning styles for some specific learning context. This work is based on theoretical references of Felder, Kolb and Gardner, proposing the implementation of a metadata annotation to identificate prime learning styles that are present in specific learning objects. This classification constitutes a starting point to recover learning objects from a repository according to apprentice’s profile and experiences. As a result, the effectiveness of the use of learning objects will be improved.

Abstract (sommario):

Abstract Memorization techniques are of primary importance in education. Two relevant and extensively used techniques are the Concept maps and the method of loci. Both methods are based on the visualization of information, which helps memorization and retrieval. For these reasons, they are also considered inclusive learning tools for people with Specific Learning Disability. Augmented Reality is a technology that has gained popularity in many sectors, from industry to the medical one, for its effectiveness in visualizing graphical items on top of real contexts. The paper demonstrates that Augmented Reality can also be beneficial for representing and interacting with Concept maps in a 3D virtual space that is linked to the real world. Specifically, the authors developed an Augmented Reality application in which the key features of both the Concept maps (such as visual-spatial logic and concepts organization) and of the method of loci are integrated with those of Augmented Reality technologies to improve the learning process and the retrieval of information.

Abstract (sommario):

"Social networks have become an important source of information, especially professional networks, where users share information about their academic and professional qualifications, skills and work experience. Nowadays, where the updating and development of professional skills is becoming more and more relevant for professionals, this information is of great interest, since it allows to know the trend of the labor market. In this regard, LinkedIn, in particular, has become one of the most widely used professional networks for this purpose, designed for professional networking and job search. From the professional profiles shared in this media, it is possible to retrieve relevant information for the labor sector, to know information about the professional profiles according to their competencies, as well as the most demanded competencies in the different job positions. This makes it possible to detect formation needs to improve or develop new skills. Additionally, LinkedIn has a particular element, the endorsements, through which it allows members of the network to acknowledge the skills of other members, which could provide information related to the level of development of a given skill. The analysis of this information, in addition to detecting training needs, can be used to adapt curricula to meet these needs, as well as in the field of human resources, to find the right candidates for the job. Currently, recommender systems have become a powerful tool for suggesting relevant articles to users. In the field of education, they have become very powerful, making it possible to link the training offer with the training needs of users, especially in the field of continuing education, in order to meet the need to develop professional skills. In a previous work, we have developed a recommendation system based on machine learning and ontology to recommend continuing education courses to LinkedIn users. As an extension of our work, we propose to incorporate the endorsement information to the user profiles to determine the improvement in the recommendations of our recommendation system. The results obtained showed an improvement in the recommendations, obtaining an accuracy of 94%."

Abstract (sommario):

This paper presents an analysis of the possibilities and advantages of augmented reality technologies and their implementation in training of future Chemistry and Biology teachers. The study revealed that the use of augmented reality technologies in education creates a number of advantages, such as: visualization of educational material; interesting and attractive learning process; increasing student motivation to study and others. Several augmented reality applications were analyzed. The Blippar app has been determined to have great benefits: it’s free; the interface is simple and user-friendly; the possibility of using different file types; the possibility of combining a large amount of information and logically structuring it; loading different types of information: video, images, 3D models, links to sites, etc. Thus, convenient interactive projects were developed using the Blippar application, which were called study guide with AR elements, and implemented in teaching chemical disciplines such as Laboratory Chemical Practice and Organic Chemistry. Using such study guide with AR elements during classes in a real chemical laboratory is safe and does not require expensive glassware. The student interviews revealed that the use of the Blippar application facilitated new material understanding, saved time needed to learn material, and was an effective addition to real-life learning.

Abstract (sommario):

This study attempted to examine user perspectives regarding the desirability of the diaphragm as a contraceptive method when included among other methods distributed freely through a family planning (FP) clinic. It sought to introduce on an experimental basis, the diaphragm into an ongoing and well-established FP clinic to increase contraceptive choice. This was primarily a qualitative study aimed at understanding women's perceptions about the risks and benefits, the reasons for use of the diaphragm, and the practical difficulties of using it effectively. It also studied the influence of service delivery factors in acceptance of this method. The study was part of a larger project of the Gender, Reproductive Health, and Population Policies research program. Information dissemination on diaphragms and other contraceptive methods was part of a comprehensive community outreach program on reproductive health education. Based on the information provided and use of the diaphragm over a month women perceived the key advantages to be the absence of side effects and the facility of need-based use. In addition, as this report notes, the diaphragm answered the needs of women who wished to space as well those who wished to limit the number of children.

Abstract (sommario):

The publication explores the features of the digital technologies’ usage to organize the work of the Young Scientists’ Councils and describes the best practices. The digital transformation of society and the quarantine restrictions caused by the COVID-19 pandemic have forced the use of various digital technologies for scientific communication, the organization of work for youth associations, and the training of students and Ph.D. students. An important role in increasing the prestige of scientific activity and encouraging talented young people to participate in scientific projects belongs to the Young Scientists’ Councils, which are created at scientific institutions and higher education institutions. It is determined that the peculiarities of the work of Young Scientists’ Councils are in providing conditions for further staff development of the institution in which they operate; contribution to the social, psychological and material support of young scientists and Ph.D. students; creating an environment for teamwork and collaborative partnership; development of leadership and organizational qualities; contribution to the development of digital competence. The advantages of using electronic social networks in higher education and research institutions are analyzed, namely: general popularity and free of charge; prompt exchange of messages and multimedia data; user-friendly interface; availability of event planning functions, sending invitations, setting reminders; support of synchronous and asynchronous communication between network participants; possibility of access from various devices; a powerful tool for organizing the learning process; possibility of organization and work of closed and open groups; advertising of various events, etc. Peculiarities of managing the activity of the Young Scientists’ Council with the use of digital technologies are determined. The Young Scientists’ Council is a social system, and therefore the management of this system refers to social management. The effectiveness of the digital technologies’ usage to manage the activities of the Young Scientists’ Council depends on the intensity and need for their use to implement organizational, presentation functions and to ensure constant communication. The areas to apply digital technologies for the work managing of Young Scientists’ Councils are sorted as the presentation of activity; distribution of various information for young scientists; conducting questionnaires, surveys; organization and holding of scientific mass events; managing of thematic workgroups, holding of work meetings. It is generalized and described the experience of electronic social networks usage for organizing and conducting of scientific mass events.
