  Soni, S. ; Lerman, K. ; Eisenstein, J.: Follow the leader : documents on the leading edge of semantic change get more citations.
  In: Journal of the Association for Information Science and Technology. 72(2021) no.4, S.478-492.
  
  Abstract: Diachronic word embeddings-vector representations of words over time-offer remarkable insights into the evolution of language and provide a tool for quantifying sociocultural change from text documents. Prior work has used such embeddings to identify shifts in the meaning of individual words. However, simply knowing that a word has changed in meaning is insufficient to identify the instances of word usage that convey the historical meaning or the newer meaning. In this study, we link diachronic word embeddings to documents, by situating those documents as leaders or laggards with respect to ongoing semantic changes. Specifically, we propose a novel method to quantify the degree of semantic progressiveness in each word usage, and then show how these usages can be aggregated to obtain scores for each document. We analyze two large collections of documents, representing legal opinions and scientific articles. Documents that are scored as semantically progressive receive a larger number of citations, indicating that they are especially influential. Our work thus provides a new technique for identifying lexical semantic leaders and demonstrates a new link between progressive use of language and influence in a citation network.

  Zigron, S. ; Bronstein, J.: "Help is where you find it" : the role of weak ties networks as sources of information and support in virtual health communities.
  In: Journal of the Association for Information Science and Technology. 70(2019) no.2, S.130-139.
  
  Abstract: Virtual health communities allow people with health-related concerns to engage in supportive communication with individuals coping with similar problems that would be difficult or impossible to form in the face-to-face world. This study examined the information interactions in an Israeli virtual health community on Facebook dealing with ulcerative colitis and Crohn's disease drawing from the "weak ties" network theory as a theoretical framework. Weak ties are social ties or acquaintances that can function as an important source for diversified experiential information and emotional support, reducing stigma and providing a sense of belonging. The study consisted of 23 semistructured interviews with registered members of the group. Findings of this study parallel the four functions of weak ties by allowing chronically ill patients: access to diverse sources of information including experiential information from others suffering from the same illness; the possibility to disclose personal information reducing fear from stigma or rejection; and a sense of belonging.

  Genuis, S.K. ; Bronstein, J.: Looking for "normal" : sense making in the context of health disruption.
  In: Journal of the Association for Information Science and Technology. 68(2017) no.3, S.750-761.
  
  Abstract: This investigation examines perceptions of normality emerging from two distinct studies of information behavior associated with life disrupting health symptoms and theorizes the search for normality in the context of sense making theory. Study I explored the experiences of women striving to make sense of symptoms associated with menopause; Study II examined posts from two online discussion groups for people with symptoms of obsessive compulsive disorder. Joint data analysis demonstrates that normality was initially perceived as the absence of illness. A breakdown in perceived normality because of disruptive symptoms created gaps and discontinuities in understanding. As participants interacted with information about the experiences of health-challenged peers, socially constructed notions of normality emerged. This was internalized as a "new normal." Findings demonstrate normality as an element of sense making that changes and develops over time, and experiential information and social contexts as central to health-related sense making. Re-establishing perceptions of normality, as experienced by health-challenged peers, was an important element of sense making. This investigation provides nuanced insight into notions of normality, extends understanding of social processes involved in sense making, and represents the first theorizing of and model development for normality within the information science and sense making literature.

  Bronstein, J. ; Gazit, T. ; Perez, O. ; Bar-Ilan, J. ; Aharony, N. ; Amichai-Hamburger, Y.: ¬An examination of the factors contributing to participation in online social platforms.
  In: Aslib journal of information management. 68(2016) no.6, S.793-818.
  
  Abstract: Purpose The purpose of this paper is to examine participation in online social platforms consisting of information exchange, social network interactions, and political deliberation. Despite the proven benefits of online participation, the majority of internet users read social media data but do not directly contribute, a phenomenon called lurking. Design/methodology/approach A survey was administered electronically to 507 participants and consisted of ten sections in a questionnaire to gather data on the relationship between online participation and the following variables: anonymity, social value orientation, motivations, and participation in offline activities, as well as the internet's political influence and personality traits. Findings Findings show that users with high levels of participation also identify themselves, report higher levels of extroversion, openness, and activity outside the internet, the motivations being an intermediary variable in the relationship between the variables value. Originality/value The study shows that participation in online social platforms is not only related to personality traits, but they are impacted by the nature of the motivations that drive them to participate in the particular social platform, as well as by the interest toward the specific topic, or the type or nature of the social group with whom they are communicating.

  Bernstein, J.H.: Nonknowledge : the bibliographical organization of ignorance, stupidity, error, and unreason: Part Two.
  In: Knowledge organization. 36(2009) no.4, S.249-260.
  
  Abstract: Starting with the Data-Information-Knowledge-Wisdom paradigm in information science, it is possible to derive a model of the opposite of knowledge having hierarchical qualities. A range of counterpoints to concepts in the knowledge hierarchy can be identified and ascribed the overall term "nonknowledge." This model creates a conceptual framework for understanding the connections between topics such as error, ignorance, stupidity, folly, popular misconceptions, and unreason, by locating them as levels or phases of nonknowledge. The concept of nonknowledge links heretofore disconnected discourses on these individual topics by philosophers, psychologists, historians, sociologists, satirists, and others. Subject headings provide access to the categories of nonknowledge, but confusion remains due to the general failure of cataloging and classification to differentiate between works about nonknowledge and examples of nonknowledge.

  Bernstein, J.H.: Nonknowledge : the bibliographical organization of ignorance, stupidity, error, and unreason: Part one.
  In: Knowledge organization. 36(2009) no.1, S.17-29.
  
  Abstract: To the extent that one can acquire knowledge through the reading of documents, it may be said that documents transmit knowledge. But what would be the opposite of knowledge? Does it have a legitimate role in library collections? Can it be broken down into categories or domains? How would it be found? Does the opposite of knowledge (let us call it nonknowledge) raise any special problems in cataloging, classification, and indexing? What kinds of subject headings for example, would apply to it? Can we find a conceptual framework with which to comprehend, classify, and retrieve it? This two-part essay aims to identify and articulate the rather paradoxical problems inherent in the organization not of knowledge (see Hjørland 2003) but of nonknowledge. Beginning with theoretical problems about modeling a paradigm of nonknowledge as the opposite of knowledge and extending it to encompass negative counterparts of phenomena related to knowledge, it continues by addressing practical questions in the organization of and access to nonknowledge in libraries, and progresses with an exposition of the categories of nonknowledge. Part one of the essay ends with a review of the concept of stupidity. Part two picks up the discussion with expositions of the remaining areas of nonknowledge. The essay concludes with observations on differentiating between works about nonknowledge and those that disseminate nonknowledge and the implications of nonknowledge for library services.

  Baruchson-Arbib, S. ; Bronstein, J.: Humanists as information users in the digital age : the case of Jewish studies scholars in Israel.
  In: Journal of the American Society for Information Science and Technology. 58(2007) no.14, S.2269-2279.
  
  Abstract: User studies provide libraries with invaluable insight into their users' information needs and behaviors, allowing them to develop services that correspond to these needs. This insight has become even more important for libraries since the advent of the Internet. The Internet has brought about a development of information technologies and electronic information sources that have had a great impact on both the ways users search for information and the ways libraries manage information. Although humanists represent an important group of users for academic libraries, research studies into their information-seeking behavior since the advent of the Internet have been quite scarce (Ellis & Oldman, 2005) in the past decade. This study presents updated research on a group of humanists, Jewish studies scholars living in Israel, as information users in the digital age based on two categories: (a) the use of formal and informal information channels, and (b) the use of information technologies and their impact on humanistic research.

  Baruchson-Arbib, S. ; Bronstein, J.: ¬A view to the future of the library and information science profession : a delphi study.
  In: Journal of the American Society for Information Science and technology. 53(2002) no.5, S.397-408.
  
  Abstract: Baruchson-Arbib and Bronstein present the results of a Delphi study held in Israel from 1998 to 2000. One hundred and twenty directors of large public and academic libraries, heads of LIS departments, and of corporate information centers in the USA, Canada, Europe, and Israel participated, using a 47 statement website as a base. Consensus on most points was reached in the first round. A second round included only 26 participants whose responses fell outside the group consensus. Seventy seven percent believe the traditional model of the library will not be replaced in their lifetimes. A user centered approach is highly favored, as is more assertive behavior including marketing and promotion. Less than 8% believe the profession will disappear.

  Blustein, J. ; Webber, R.E. ; Tague-Sutcliffe, J.: Methods for evaluating the quality of hypertext links.
  In: Information processing and management. 33(1997) no.2, S.255-271.
  
  Abstract: Presents 2 methods for evaluating automatically generated hypertext links. The 1st method is based on correlations between shortest paths in the hypertext structure and a semantic similarity measure. Experimental results with the 1st methods show the degree to which the hypertext conversion process approximates semantic similarity. The semantic measure is in turn only an approximation of a user's internal model of the corpus. Proposes a 2nd evaluation method based on measuring user's performance using hypertext. Discusses the advantages and disadvantages of computer versus human evaluation

  Rogalla von Bieberstein, J.A.: Moderne oder historische Musikinstrumente? : ein Katalogisierungsproblem.
  Hamburg : FH, Fb Bibliothekswesen, 1997. 89 S.
  
  Abstract: Untersucht wird die Katalogisierung von Musikalien und Musiktontrögern nach Stimmen- und Interpretbesetzungen, um auch Recherchen nach Interpretennamen und Gesang- und Instrumentalstimmen zu ermöglichen. Dieses ist bisher in OPACs nicht endgültig gelöst. Es wird ein Weg für den PICA-OPAC aufgezeigt, eine Erweiterung des PICA-3-Kategorienschemas vorgeschlagen und am Beispiel der Katalogisierung von Tonträgern mit historischen oder modernen Blechblasinstrumenten illustriert

  Stein, J.: LISA's move from SilverPlatter to Bowker : looking at the interface.
  In: Electronic Library. 12(1994) no.1, S.5-10.
  
  Abstract: LISA will no longer be produced by SilverPlatter; it is being replaced by Bowker-Saur's LISA Plus (Online Computer Systems). The two products are compared with regards to the user interface software, particularly from the aspects of functionality and ease of use. It is concluded that, from this viewpoint, the change may not be an entirely welcome one
