1Tang, R.T. ; Mehra, B. ; BorgmaDun, J.T. ; Zhao, Y.(C).: Framing a discussion on paradigm shift(s) in the field of information.
In: Journal of the Association for Information Science and Technology. 72(2021) no.2, S.253-258.
Abstract: In this opinion paper, we frame a discussion on paradigm shift(s) in the field of information. We believe that in this astonishing historical moment of new directions and new opportunities both the existing paradigms and conceptual models in the field of information can benefit from re-examination to stay current with the times. We propose a framework articulating key narratives associated with the why, what, how, and who dimensions to discuss paradigm shift(s). The purpose of this opinion paper is to initiate dialogues on ground-breaking ideas and innovative solutions as well as support research that addresses contemporary challenges in the field of information.

Abstract: Wirft man einen Blick auf die Kernthemen der Informationswissenschaft, so wird schnell deutlich, dass sie sich eben nicht nur mit Information beschäftigt, sondern auch mit dem, was sich idealerweise aus der Verarbeitung von Information - vor allem bezogen auf die Menschen - ergibt: Wissen.

3Tang, R. ; Safer, M.A.: Author-rated importance of cited references in biology and psychology publications.
In: Journal of documentation. 64(2008) no.2, S.246-272.
Abstract: Purpose - The present study aims to investigate how textual features, depth of citation treatment, reasons for citation, and relationships between citers and citees predict author-rated citation importance. Design/methodology/approach - A total of 49 biology and 50 psychology authors assessed the importance, reason for citation, and relationship to the cited author for each cited reference in his or her own recently published empirical article. Participants performed their evaluations on individualized web-based surveys. Findings - The paper finds that certain textual features, such as citation frequency, citation length, and citation location, as well as author-stated reasons for citation predicted ratings of importance, but the strength of the relationship often depended on citation features in the article as a whole. The relationship between objective citation features and author-rated importance also tended to be weaker for self-citations. Research limitations/implications - The study sample included authors of relatively long empirical articles with a minimum of 35 cited references. There were relatively few disciplinary differences, which suggests that citation behavior in psychology may be similar to that in natural science disciplines. Future studies should involve authors from other disciplines employing diverse referencing patterns in articles of varying lengths and types. Originality/value - Findings of the study have enabled a comprehensive, profound level of understanding of citation behaviors of biology and psychology authors. It uncovered a number of unique characteristics in authors' citation evaluations, such as article-level context effects and rule- versus affective-based judgments. The paper suggests possible implications for developing retrieval algorithms based on automatically predicted importance of cited references.

In: Journal of the American Society for Information Science and Technology. 57(2006) no.9, S.1155-1164.
Abstract: The authors report on a series of experiments to automate the assessment of document qualities such as depth and objectivity. The primary purpose is to develop a quality-sensitive functionality, orthogonal to relevance, to select documents for an interactive question-answering system. The study consisted of two stages. In the classifier construction stage, nine document qualities deemed important by information professionals were identified and classifiers were developed to predict their values. In the confirmative evaluation stage, the performance of the developed methods was checked using a different document collection. The quality prediction methods worked well in the second stage. The results strongly suggest that the best way to predict document qualities automatically is to construct classifiers on a person-by-person basis.

7Tang, R. ; Solomon, P.: Use of relevance criteria across stages of document evaluation : on the complementarity of experimental and naturalistic studies.
In: Journal of the American Society for Information Science and technology. 52(2001) no.8, S.676-687.
Abstract: Tang and Solomon, based upon their review of the history of topical and other than topical criteria in relevance evaluation, decide to look at a two stage model where judgements are first made on surrogate records and then on full document text to determine if a criteria shift takes place and if so in what manner and to what degree. Both a controlled experiment and a naturalistic study were used to study the staging of relevance judgement criteria. In the controlled environment 90 undergraduate Psychology students were instructed to choose papers that would help them meet an assignment from 20 preselected papers on broader topic that included that assigned. They first selected on the basis of citation and abstract, then read the papers, and in each process filled out a questionnaire on the importance of each of 15 criteria at each stage of the two-stage process. In the naturalistic study 9 Ph.D. Psychology students conducted literature searches to support their own research and were asked to think aloud while making their decisions from retrieved surrogates, and later filled out a questionnaire while reading those materials that they selected and then interviewed at the end of the process. Apparently understandability is important at both stages. Importance increased at stage two. Cognitive criteria do not all follow the same pattern across stages. The controlled group thought quality of information was most important in stage one and topicality most important in stage 2. In the naturalistic study topicality was most frequent for stage one and research structure for stage two. A classification of criteria by their functionality is suggested as a better approach. First a division as to whether a criterion is objectively associated with the document as opposed to being subjectively associated with a person's expectations; then a division based on primary (essential) or secondary (for assistance) status.
8Tang, R. ; Shaw, W.M. ; Vevea, J.L.: Towards the identification of the optimal number of relevance categories.
In: Journal of the American Society for Information Science. 50(1999) no.3, S.254-264.
Abstract: In this paper, we are concerned with participants' confidence in their judgements of the relevance of bibliographic records to particular research questions. We describe an empirical investigation of the association between judges' confidence and the number of categories for a relevance rating scale. Participants rated the relevance of bibliographic records, and recorded their confidence in the relevance ratings. We hypothesize that confidence in relevance judgements is a function of the number of relevance categories that are available in the rating scale. We consider scales ranging from 2 to 11 points, and define the optimal scale as the one for which participants express a maximum level of confidence. A pilot study finds no optimal number of points (because confidence continues to improve slightly through the 11-point scale); nevertheless, the study shows little added benefit associated with scales that have more than six points. On the basis of the findings in that study, we adjusted our experimental procedures and found, in our principal study, that the optimal scale for maximizing confidence in relevance judgements has approximately seven points. We also present exploratory results involving gender effects, and the comparison of scales that have an odd number of points (for which a neutral judgement is possible) with scales that have an even number of points

In: Information processing and management. 34(1998) nos.2/3, S.237-256.
Abstract: Investigates the cognitive nature of an end-user's relevance judgements using the concept of mental modes. Identifies situational factors of relevance by noting the judgement criteria used by subjects as they move through the relevance judgement process. Tests the feasibility of the specific research strategy employed in this study that incorporates an intensive case study of the search behaviour of searchers with naturalistic inquiry for which the cognitive development and situational factors of end-user relevance judgements are the centre of the investigation. Introduces a dynamic model or relevance on which the study is built, presents methodology, results and discussion
