    Abstract
    In this article recording evidence for data values in addition to the values themselves in bibliographic records and descriptive metadata is proposed, with the aim of improving the expressiveness and reliability of those records and metadata. Recorded evidence indicates why and how data values are recorded for elements. Recording the history of changes in data values is also proposed, with the aim of reinforcing recorded evidence. First, evidence that can be recorded is categorized into classes: identifiers of rules or tasks, action descriptions of them, and input and output data of them. Dates of recording values and evidence are an additional class. Then, the relative usefulness of evidence classes and also levels (i.e., the record, data element, or data value level) to which an individual evidence class is applied, is examined. Second, examples that can be viewed as recorded evidence in existing bibliographic records and current cataloging rules are shown. Third, some examples of bibliographic records and descriptive metadata with notes of evidence are demonstrated. Fourth, ways of using recorded evidence are addressed.

    Abstract
    Mark Stapleton and Matt Adamson began their presentation by describing how Dow Jones' Factiva range of information services processed an average of 170,000 documents every day, drawn from over 10,000 sources in 22 languages. These documents are categorized within five facets: Company, Subject, Industry, Region and Language. The digital feeds received from information providers undergo a series of processing stages, initially to prepare them for automatic categorization and then to format them ready for distribution. The categorization stage is able to handle 98% of documents automatically, the remaining 2% requiring some form of human intervention. Depending on the source, categorization can involve any combination of 'Autocoding', 'Dictionary-based Categorizing', 'Rules-based Coding' or 'Manual Coding'

    Abstract
    In a research project focusing on knowledge organization and classification education, 407 learning objectives proposed in courses entirely or partially dedicated to these subjects in North American Library and Information Science programs were categorized with the help of the Benjamin Bloom's Taxonomy of cognitive objectives. The analysis reveals that the vast majority of course objectives remain at the lower levels of the Taxonomy. These results tend to reinforce observations made over the past 30 years in relation to KO and classification education. While KO and classification educators recognize the necessity for students to develop high-level analytic and evaluative skills, there are few references to those skills in current course objectives.

    Abstract
    Purpose - In today's knowledge-based economy, knowledge networks (KN) increasingly are becoming vital channels for pursuing strategic objectives in project-based organizations (PBO), in which the project is the basic organizational element in its operation. KN initiatives often are started with the selection of a creation methodology, which involves complex decisions for successful implementation. Thus, the purpose of this paper is to address this critical selection of methodology and proposes a holistic framework for selecting an appropriate methodology in this kind of flatter, speedier, and more flexible organizational form. Design/methodology/approach - In the first step, the study established a theoretical background addressing the problem of KN creation in PBO. The second step defined selection criteria based on extensive literature review. In the third step, a holistic framework was constructed based on different characteristics of existing methodologies categorized according to the selected criteria. Finally, the suggested framework was empirically tested in a project-based firm and the case study and the results are discussed. Findings - A holistic framework was determined by including different aspects of a KN such as network perspectives, tools and techniques, objectives, characteristics, capabilities, and approaches. The proposed framework consisted of ten existing KN methodologies that consider qualitative and quantitative dimensions with micro and macro approaches. Originality/value - The development of the theory of KN creation methodology is the main contribution of this research. The selection framework, which was theoretically and empirically grounded, has attempted to offer a more rational and less ambiguous solution to the KN methodology selection problem in PBO forms.

    Abstract
    Categorized overviews of web search results are a promising way to support user exploration, understanding, and discovery. These search interfaces combine a metadata-based overview with the list of search results to enable a rich form of interaction. A study of 24 sophisticated users carrying out complex tasks suggests how searchers may adapt their search tactics when using categorized overviews. This mixed methods study evaluated categorized overviews of web search results organized into thematic, geographic, and government categories. Participants conducted four exploratory searches during a 2-hour session to generate ideas for newspaper articles about specified topics such as "human smuggling." Results showed that subjects explored deeper while feeling more organized, and that the categorized overview helped subjects better assess their results, although no significant differences were detected in the quality of the article ideas. A qualitative analysis of searcher comments identified seven tactics that participants reported adopting when using categorized overviews. This paper concludes by proposing a set of guidelines for the design of exploratory search interfaces. An understanding of the impact of categorized overviews on search tactics will be useful to web search researchers, search interface designers, information architects and web developers.

    Abstract
    The development of visual retrieval methods requires information about user interaction with images, including their description and categorization. This article presents the development of a categorization model for magazine images based on two user studies. In Study 1, we elicited 10 main classes of magazine image categorization criteria through sorting tasks with nonexpert and expert users (N=30). Multivariate methods, namely, multidimensional scaling and hierarchical clustering, were used to analyze similarity data. Content analysis of category names gave rise to classes that were synthesized into a categorization framework. The framework was evaluated in Study 2 by experts (N=24) who categorized another set of images consistent with the framework and found it to be useful in the task. Based on the evaluation study the framework was solidified into a model for categorizing magazine imagery. Connections between classes were analyzed both from the original sorting data and from the evaluation study and included into the final model. The model is a practical categorization tool that may be used in workplaces, such as magazine editorial offices. It may also serve to guide the development of computational methods for image understanding, selection of concepts for automatic detection, and approaches to support browsing and exploratory image search.

    Abstract
    Scholarly domains have been analyzed using various tools and techniques to reveal complex genealogies of scholarship, authorship, citation and ontology, resulting in not only deeper knowledge of each area studied, but in a better developed set of methodologies for domain exploration in general. While domain analysis itself is being used frequently in LIS, there remain many areas against which domain analytical tools have not yet been applied. This is the case with encyclopedic collections of knowledge, such as that which is being developed as the Encyclopedia of Milwaukee (EMKE) within the history department at the University of Wisconsin-Milwaukee. This descriptive study will analyze resources categorized under race and ethnicity from a comprehensive bibliography on the history of metropolitan Milwaukee that was designed to serve those who would research and write entries for the EMKE. Bibliometric and analytic techniques are employed to explore the intension and extension of the domain as it is developing.

    Abstract
    Purpose - This article aims to describe how people manage to integrate their use of paper and electronic documents in modern office work environments. Design/methodology/approach - An observational interview type study of 14 participants from 11 offices in eight organizations was conducted. Recorded data were analysed using a thematic analysis method. This involved reading and annotation of interview transcripts, categorizing, linking and connecting, corroborating, and producing an account of the study. Findings - The findings of the study can be categorized into four groups: the roles paper and electronic documents serve in today's offices, the ways in which these documents are managed, the problems associated with their management, and the types of fragmentation that exist in terms of their management and how these are dealt with. Practical implications - The study has identified the need for better integrated management of paper and electronic documents in present-day offices. The findings of the study have then been used to propose a set of guidelines for the development of integrated paper and electronic document management systems. Originality/value - Although similar studies of offices have been conducted in the past, almost all of these studies are prior to the widespread use of mobile and network-based shared technologies in office environments. Furthermore, previous studies have generally failed to identify and propose guidelines for integration of paper and electronic document management systems.

    Abstract
    The purpose of this study was to examine user tags that describe digitized archival collections in the field of humanities. A collection of 8,310 tags from a digital portal (Nineteenth-Century Electronic Scholarship, NINES) was analyzed to find out what attributes of primary historical resources users described with tags. Tags were categorized to identify which tags describe the content of the resource, the resource itself, and subjective aspects (e.g., usage or emotion). The study's findings revealed that over half were content-related; tags representing opinion, usage context, or self-reference, however, reflected only a small percentage. The study further found that terms related to genre or physical format of a resource were frequently used in describing primary archival resources. It was also learned that nontextual resources had lower numbers of content-related tags and higher numbers of document-related tags than textual resources and bibliographic materials; moreover, textual resources tended to have more user-context-related tags than other resources. These findings help explain users' tagging behavior and resource interpretation in primary resources in the humanities. Such information provided through tags helps information professionals decide to what extent indexing archival and cultural resources should be done for resource description and discovery, and understand users' terminology.

    Abstract
    With the wide application of keyphrases in many Information Retrieval (IR) and Natural Language Processing (NLP) tasks, automatic keyphrase prediction has been emerging. However, these statistically important phrases are contributing increasingly less to the related tasks because the end-to-end learning mechanism enables models to learn the important semantic information of the text directly. Similarly, keyphrases are of little help for readers to quickly grasp the paper's main idea because the relationship between the keyphrase and the paper is not explicit to readers. Therefore, we propose to generate keyphrases with specific functions for readers to bridge the semantic gap between them and the information producers, and verify the effectiveness of the keyphrase function for assisting users' comprehension with a user experiment. A controllable keyphrase generation framework (the CKPG) that uses the keyphrase function as a control code to generate categorized keyphrases is proposed and implemented based on Transformer, BART, and T5, respectively. For the Computer Science domain, the Macro-avgs of , , and on the Paper with Code dataset are up to 0.680, 0.535, and 0.558, respectively. Our experimental results indicate the effectiveness of the CKPG models.

    Abstract
    The article explains content analysis, a method whereby statements taken from oral or written library user comments are labeled as particular speech acts. These speech acts are then categorized into the three behavioral domains: affective, cognitive, and sonsorimotor, ansd used to construct user-based instructional objectives

    Abstract
    Purpose - The purpose of this paper is to get a first approximation of the usefulness of online forums with regard to information seeking and knowledge generation. Design/methodology/approach - This study captures the characteristics of knowledge generation by examining the pragmatics and types of information needs of posted questions and by investigating knowledge related characteristics of discussion posts as well as the success of communication. Three online forums were examined. The data set consists of 55 threads, containing 533 posts which were categorized manually by two researchers. Findings - Results show that questioners often ask for personal estimations. Information needs often aim for actionable insights or uncertainty reduction. With regard to answers, factual information is the dominant content type and has the highest knowledge value as it is the strongest predictor with regard to the generation of new knowledge. Opinions are also relevant, but in a rather subsequent and complementary way. Emotional aspects are scarcely observed. Overall, results indicate that knowledge creation predominantly follows a socio-cultural paradigm of knowledge exchange. Research limitations/implications - Although the investigation captures important aspects of knowledge building processes, the measurement of the forums' knowledge value is still rather limited. Success is only partly measurable with the current scheme. The central coding category "new topical knowledge" is only of nominal value and therefore not able to compare different kinds of knowledge gains in the course of discussion. Originality/value - The investigation reaches out beyond studies that do not consider that the role and relevance of posts is dependent on the state of the discussion. Furthermore, the paper integrates two perspectives of knowledge value: the success of the questioner with regard to the expressed information need and the knowledge building value for communicants and readers.
