TL;DR: Results of the study indicate a pressing need for the building of a common data model that is interoperable across digital repositories.
Abstract: This study presents the current state of research and practice on metadata quality through focus on the functional perspective on metadata quality, measurement, and evaluation criteria coupled with mechanisms for improving metadata quality. Quality metadata reflect the degree to which the metadata in question perform the core bibliographic functions of discovery, use, provenance, currency, authentication, and administration. The functional perspective is closely tied to the criteria and measurements used for assessing metadata quality. Accuracy, completeness, and consistency are the most common criteria used in measuring metadata quality in the literature. Guidelines embedded within a Web form or template perform a valuable function in improving the quality of the metadata. Results of the study indicate a pressing need for the building of a common data model that is interoperable across digital repositories.

TL;DR: The results of this study show that it is possible to use social tags to improve the accessibility of library collections, however, the existence of non-subject-related tags may impede the application of social tagging in traditional library cataloguing systems.
Abstract: Social tagging, as a recent approach for creating metadata, has caught the attention of library and information science researchers. Many researchers recommend incorporating social tagging into the library environment and combining folksonomies with formal classification. However, some researchers are concerned with the quality issues of social annotation because of its uncontrolled nature. In this study, we compare social tags created by users from the LibraryThing website with the subject terms assigned by experts according to the Library of Congress Subject Headings (LCSH). The purpose of this study is to examine the difference and connections between social tags and expert-assigned subject terms and further explore the feasibility and obstacles of implementing social tagging in library systems. The results of our study show that it is possible to use social tags to improve the accessibility of library collections. However, the existence of non-subject-related tags may impede the application of social tagging in traditional library cataloguing systems.

TL;DR: Results show that MARC, AACR2, and LCSH are the most widely used metadata schema, content standard, and subjectcontrolled vocabulary, respectively, followed by EAD, MODS, VRA, and TEI.
Abstract: This study explores the current state of metadata-creation practices across digital repositories and collections by using data collected from a nationwide survey of mostly cataloging and metadata professionals. Results show that MARC, AACR2, and LCSH are the most widely used metadata schema, content standard, and subjectcontrolled vocabulary, respectively. Dublin Core (DC) is the second most widely used metadata schema, followed by EAD, MODS, VRA, and TEI. Qualified DC’s wider use vis-a-vis Unqualified DC (40.6 percent versus 25.4 percent) is noteworthy. The leading criteria in selecting metadata and controlled-vocabulary schemata are collection-specific considerations, such as the types of resources, nature of the collection, and needs of primary users and communities. Existing technological infrastructure and staff expertise also are significant factors contributing to the current use of metadata schemata and controlled vocabularies for subject access across distributed digital repositories and collections. Metadata interoperability remains a major challenge. There is a lack of exposure of locally created metadata and metadata guidelines beyond the local environments. Homegrown locally added metadata elements may also hinder metadata interoperability across digital repositories and collections when there is a lack of sharable mechanisms for locally defined extensions and variants.

TL;DR: This article examined the communication of text-based synchronous online discussion (chat) participants during the process of information sharing, and analyzed the mechanisms participants employed to overcome these constraints, and described the characteristics of information seeking in chat interaction.
Abstract: This article examines the communication of text‐based synchronous online discussion (chat) participants during the process of information sharing. It addresses the communicational constraints imposed by the computer‐mediated communication (CMC) channel on participants’ expression of interpersonal and affective stances, analyzes the mechanisms participants employed to overcome these constraints, and describes the characteristics of information seeking in chat interaction. Data for this study are derived from a math help chat group for K–12 students, facilitated by the Virtual Math Teams at Drexel University. Participants employed a variety of creative linguistic and paralinguistic devices to express interpersonal and affective stances, such as contractions of linguistic forms, prosodic features, and typographical conventions such as capital letters and emoticons to simulate gesture and facial expressions. The analysis of data suggests that effective interpersonal and emotional communication is a critical f...

TL;DR: An online survey of cataloging and metadata professionals in the United States examines the perceived importance of metadata quality, metadata quality evaluation criteria and issues, and mechanisms for building quality assurance into the metadata creation process.
Abstract: This article evaluates practices on metadata quality control in digital repositories and collections using an online survey of cataloging and metadata professionals in the United States. The study examines (1) the perceived importance of metadata quality, (2) metadata quality evaluation criteria and issues, and (3) mechanisms for building quality assurance into the metadata creation process. The survey finds wide recognition of the essential role of metadata quality assurance. Accuracy and consistency are prioritized as the main criteria for metadata quality evaluation. Metadata semantics greatly affects consistent and accurate metadata application. Strong awareness of metadata quality correlates with the widespread adoption of various quality control mechanisms, such as staff training, manual review, metadata guidelines, and metadata generation tools. And yet, metadata guidelines are used less frequently as a quality assurance mechanism in digital collections involving multiple institutions.

TL;DR: The Encyclopedia of Linguistics explores the varied perspectives, figures, and methodologies that make up the field through a historical and international approach.
Abstract: Book synopsis: Utilizing a historical and international approach, this valuable two-volume resource makes even the more complex linguistic issues understandable for the non-specialized reader. Containing over 500 alphabetically arranged entries and an expansive glossary by a team of international scholars, the Encyclopedia of Linguistics explores the varied perspectives, figures, and methodologies that make up the field.

TL;DR: The broad history of research on information-seeking behavior over the last 50–60 years is reviewed, major landmarks are identified, and current directions in research are discussed.
Abstract: Information behavior” is the currently preferred term used to describe the many ways in which human beings interact with information, in particular, the ways in which people seek and utilize information. The broad history of research on information-seeking behavior over the last 50–60 years is reviewed, major landmarks are identified, and current directions in research are discussed.
