- Abstract
- On a scientific concept hierarchy, a parent concept may have a few attributes, each of which has multiple values being a group of child concepts. We call these attributes facets: classification has a few facets such as application (e.g., face recognition), model (e.g., svm, knn), and metric (e.g., precision). In this work, we aim at building faceted concept hierarchies from scientific literature. Hierarchy construction methods heavily rely on hypernym detection, however, the faceted relations are parent-to-child links but the hypernym relation is a multi-hop, i.e., ancestor-to-descendent link with a specific facet "type-of". We use information extraction techniques to find synonyms, sibling concepts, and ancestor-descendent relations from a data science corpus. And we propose a hierarchy growth algorithm to infer the parent-child links from the three types of relationships. It resolves conflicts by maintaining the acyclic structure of a hierarchy.

- Abstract
- I analyze the text of an article that appeared in this journal in 2007 that published the results of a questionnaire in which a number of experts were asked to define the concepts of data, information, and knowledge. I apply standard information retrieval techniques to build a list of the most frequent terms in each set of definitions. I then apply information extraction techniques to analyze how the top terms are used in the definitions. As a result, I draw data-driven conclusions about the aggregate opinion of the experts. I contrast this with the original analysis of the data to provide readers with an alternative viewpoint on what the data tell us.

- Abstract
- Catalogers have become fluent in information technology such as web design skills, HyperText Markup Language (HTML), Cascading Stylesheets (CSS), eXensible Markup Language (XML), and programming languages. The knowledge gained from learning information technology can be used to experiment with methods of transforming one metadata schema into another using various software solutions. This paper will discuss the use of eXtensible Stylesheet Language Transformations (XSLT) for repurposing, editing, and reformatting metadata. Catalogers have the requisite skills for working with any metadata schema, and if they are excluded from metadata work, libraries are wasting a valuable human resource.

- Abstract
- Marketing professionals' work activities are heavily reliant on access to and the use of large amounts of quality information. This study aims to examine the information journey experienced by marketing professionals, including task-driven information seeking, information judgments, information use, and information sharing, from a more contextualized and holistic viewpoint. The information journey presents a more comprehensive picture of user-information interaction than is usually offered in the literature. Using a diary method and post-diary in-depth interviews, data consisting of 1,198 diary entries relating to 101 real work tasks were collected over a period of 5 work days. The data were used to ascertain characteristics of the stages of marketing professionals' information journeys as well as the relationships between them. Five stages of the information journey, including determining the need for work task-generated information, seeking such information, judging and evaluating the information found, making sense of and using the obtained information, and sharing the obtained or assembled information, were identified. The information journey also encompassed types of gaps and gap-bridge techniques that occurred during information seeking and use. Based on the empirical findings, an information journey model was developed. The implications for information systems design solutions that enable different stages of the information journey to be linked together are also discussed.

- Abstract
- The proliferation of digital knowledge repositories (DKRs) used for distributed and collocated work raises important questions about how to manage these technologies. This study investigates why individuals contribute information to DKRs by applying and extending transactive memory theory. Data from knowledge workers (N = 208) nested in work groups (J = 17) located in Europe and the United States revealed, consistent with transactive memory theory, that perceptions of experts' retrieval of information were positively related to the likelihood of information provision to DKRs. The relationship between experts' perceptions of retrieval and information provision varied from group to group, and cross-level interactions indicated that trust in how the information would be used and the interdependence of tasks within groups could explain that variation. Furthermore, information provision to DKRs was related to communication networks in ways consistent with theorizing regarding the formation of transactive memory systems. Implications for theory and practice are discussed, emphasizing the utility of multilevel approaches for conceptualizing and modeling why individuals provide information to DKRs.

- Abstract
- Few studies have been done concerning document components and their effects on information use. This research empirically tested a taxonomy of functional units in a prototype journal system. This taxonomy was developed by identifying functions of the smallest information units within four journal article components (i.e., introduction, methods, results, discussion), and their associations with information tasks of using journal articles. Experimental results show that functional units can be utilized in supporting navigation, close reading, comprehension, and information use of journal articles to various extents. The results provide evidence that an individual functional unit has varying relevance to information use tasks, and has varying relevance to other functional units in the same or another component for a particular task. This research suggests that the information within a journal article can be organized and presented by functions to enhance effectiveness and efficiency in reading process and reading outcome.

- Abstract
- This article aims to identify whether different weighted PageRank algorithms can be applied to author citation networks to measure the popularity and prestige of a scholar from a citation perspective. Information retrieval (IR) was selected as a test field and data from 1956-2008 were collected from Web of Science. Weighted PageRank with citation and publication as weighted vectors were calculated on author citation networks. The results indicate that both popularity rank and prestige rank were highly correlated with the weighted PageRank. Principal component analysis was conducted to detect relationships among these different measures. For capturing prize winners within the IR field, prestige rank outperformed all the other measures

- Abstract
- Large, data-rich organizations have tremendously large collections of digital objects to be "repurposed," to respond quickly and economically to publishing, marketing, and information needs. Some management typically assume that a content management system, or some other technique such as OWL and RDF, will automatically address the workflow and technical issues associated with this reuse. Four case studies show that the sources of some roadblocks to agile repurposing are as much managerial and organizational as they are technical in nature. The review concludes with suggestions on how digital object repurposing can be integrated given these organizations' structures.

- Abstract
- All text is ephemeral. Some texts are more ephemeral than others. The web has proved to be among the most ephemeral and changing of information vehicles. The research note revisits Koehler's original data set after about 20 years since it was first collected. By late 2013, the number of URLs responding to a query had fallen to 1.6% of the original sample. A query of the 6 remaining URLs in February 2015 showed only 2 still responding.

- Abstract
- In this global information age, accessing, disseminating, and controlling information is an increasingly important aspect of human life. Often, these interests are expressed in the language of human rights-for example, rights to expression, privacy, and intellectual property. As the discipline concerned with "facilitating the effective communication of desired information between human generator and human user" (Belkin, 1975, p. 22), library and information science (LIS) has a central role in facilitating communication about human rights and ensuring the respect for human rights in information services and systems. This paper surveys the literature at the intersection of LIS and human rights. To begin, an overview of human rights conventions and an introduction to human rights theory is provided. Then the intersections between LIS and human rights are considered. Three central areas of informational human rights-communication, privacy, and intellectual property-are discussed in detail. It is argued that communication rights in particular serve as a central linchpin in the system of human rights.
