The availability of such logs has produced a wealth of research and development over the past decade on search patterns for Web search engines, intranet search services, target advertising, and Website design. These Web logs can certainly be rich sources of both personal data and user behavior. The availability of such data has resulted in significant advances in personalization, targeted search, and information push. However, these logs provide challenges and risks, along with opportunities. Panel members will discuss which critical research challenges need to be addressed in the near future. The panel members will also engage in a dialogue with audience members to develop an agenda for advancing the state of Web transaction and search log research on collecting Web log data, sharing data, addressing user privacy, analysis tools, and techniques to aid in Web log analysis.

An exploration of search session patterns in an image-based digital library

Eleven types of user actions were identified from the log content. The study is novel in its combined analytical techniques and use of clickstream data from an image-based digital library. Three analytical techniques were used to analyse the data: (a) network analysis to better understand the relationship between sequential actions; (b) sequential pattern mining to identify frequent action sequences; and (c) k-means cluster analysis to identify groups of session patterns. The analysis revealed strong ties between several pairs of actions, relatively short pattern sequences that frequently duplicate previous actions and largely uniform session behaviour with little individual item browsing within sessions, indicating users are primarily engaged in purposeful and directed searching. Developers of image-based digital libraries should consider design features that support rapid browsing.

The findings reveal essentially linear growth in the number of contributions, as institutions housing library and information science programs contribute the most publications. The largest growth was observed in the area of information behaviour, where greater levels of author and inter-institutional co-authorship have been observed in recent years.

We then compare the AKCA method with the author bibliographic coupling analysis (ABCA) method in terms of first-and all-author citation counts. We obtain the following findings: (1) The AKCA method is a new and feasible method for visualizing a discipline's structure, and the ABCA and AKCA methods have their respective strengths and emphases. The relation within the ABCA method is based on the same references (knowledge base), whereas that within the AKCA method is based on the same keywords (lexical linguistic). The AKCA method appears to provide a less detailed picture, and more uneven sub-areas of a discipline structure. The relationships between authors are narrow and direct and feature multiple levels in AKCA. (2) All-author coupling provides a comprehensive picture; thus, a complete view of a discipline structure may require both first-and all-author coupling analyses. (3) Information science evolved continuously during the second decade of the World Wide Web. The KDA (knowledge domain analysis) camp became remarkably prominent, while the IR camp (information retrieval) experienced a further decline in hard IR research, and became significantly smaller; Patent analysis and Open Access emerged during this period. Mapping of Science and Bibliometric evaluation also experienced substantial growth.

Growing pressures placed on researchers to increase their publication counts may encourage them to publish shorter papers, so that more publications may be generated from the same project and program. Is this the case? Furthermore, do shorter papers garner the same impact as longer papers as measured by the citations received? This research examines the relationship between article length and citations received by articles published in three prominent top biomedical research journals over the lifetime of the journals. The study reveals that instead of getting shorter, articles in these journals are getting longer over time. Longer articles in these journals, on average, attract more citations, and are therefore considered more impactful.

Pensando nisso, o trabalho objetiva analisar a contribuicao dos autores e sua posicao na lista de autoria em artigos publicados em coautoria no Journal of Informetrics em 2016. De forma especifica, objetiva identificar o tipo de coautoria mais recorrente e descrever a contribuicao relativa dos autores e sua posicao na linha de autoria, a partir a lista de contribuicao. Recuperaram-se os 41 artigos em coautoria publicados em 2016 que apresentavam a lista de contribuicao dos autores. A relacao entre contribuicao e a ordem da autoria foi analisada partir da construcao de uma Tabela com valores referentes a participacao dos auto...

Outcomes for the author topical similarity measure are compared to existing co-authorships in the dataset using UCINET/NetDraw. We demonstrate how author topical similarity outcomes provide a similar, but more complete, picture of author relationships than the co-authorship network. Nonparametric correlation analysis results of author topical similarity, co-authorship, citation, and co-citation were also compared for thirty author pairs of differing author topical similarity values. There is a significant correlation between author topical similarity and co-authorship and direct citation-based measures for high similarity author pairs, but not with co-citation measures. The author topical similarity measure, therefore, may se...

Thus, it describes the functions of the 'author' discussed by Foucault that can assist to reveal the characteristics of the scientific practice and examples of how theories are materialized. As a result, it identifies the ways in which modern science is developed and how knowledge is construed by multiple authors, group authors, the merit that is attributed by citations, etc. This article highlights the complexity of authorship attribution and the need to rethink generalized bibliometric techniques to evaluate science considering other aspects that go beyond the mere listing of the authors.

This research sheds light on the current status of formal software citation that is captured by citation databases. Data for the study were gathered from more than 67,000 research software records available in public repositories indexed by Clarivate Analytics' Data Citation Index (DCI). The metadata characteristics of the indexed records and citation data were then analyzed. Research software was rarely cited in the DCI, suggesting that the documented reuse of research software rarely occurs or is not well documented. Institutional repositories attracted few citations and had low rate of citation. It proved impossible, however, using the available data to isolate specific identifiers that can promote formal software citation. The findings presented here offer insights into research software citation that will be of interest to funding agencies, publishers, researchers, and research organizations.

Based on the 2013 Journal Citation Report, 30 journals with high impact factors in the library and information science (LIS) field were identified as top‐tier journals. Through the investigation, the Journal of the American Society for Information Science and Technology (JASIST), College & Research Libraries (CRL), and Scientometrics are the most prevalent LIS journals with 2668, 1730, and 625 mentions, separately, on Twitter. To explore the association between the proposed altmetrics indicator and citation‐based measures, Spearman's rho nonparametric correlation analysis was conducted to test the correlations between Twitter mentions and 8 citation‐based measures (total cites, impact factor, 5‐year impact factor, immediacy index, articles, cited half‐life, Eigenfactor score, and article influence score). Th...
