Cross-concordances: terminology mapping and its effectiveness for information retrieval

The German Federal Ministry for Education and Research funded a major terminology mapping initiative, which found its conclusion in 2007. The task of this terminology mapping initiative was to organize, create and manage 'cross-concordances' between controlled vocabularies (thesauri, classification systems, subject heading lists) centred around the social sciences but quickly extending to other subject areas. 64 crosswalks with more than 500,000 relations were established. In the final phase of the project, a major evaluation effort to test and measure the effectiveness of the vocabulary mappings in an information system environment was conducted. The paper reports on the cross-concordance work and evaluation results.Comment: 19 pages, 4 figures, 11 tables, IFLA conference 200

Natural language processing

Beginning with the basic issues of NLP, this chapter aims to chart the major research activities in this area since the last ARIST Chapter in 1996 (Haas, 1996), including: (i) natural language text processing systems - text summarization, information extraction, information retrieval, etc., including domain-specific applications; (ii) natural language interfaces; (iii) NLP in the context of www and digital libraries ; and (iv) evaluation of NLP systems

Access to recorded interviews: A research agenda

Recorded interviews form a rich basis for scholarly inquiry. Examples include oral histories, community memory projects, and interviews conducted for broadcast media. Emerging technologies offer the potential to radically transform the way in which recorded interviews are made accessible, but this vision will demand substantial investments from a broad range of research communities. This article reviews the present state of practice for making recorded interviews available and the state-of-the-art for key component technologies. A large number of important research issues are identified, and from that set of issues, a coherent research agenda is proposed

Content Analysis of Social Tags on Intersectionality for Works on Asian Women: An Exploratory Study of LibraryThing

This study explores how the social tags are employed by users of LibraryThing, a popular web 2.0 social networking site for cataloging books, to describe works on Asian women in representing themes within the context of intersectionality. Background literature in the domain of subject description of works has focused on race and gender representation within traditional controlled vocabularies such as the Library of Congress Subject Headings (LCSH). This study explores themes related to intersectionality in order to analyze how users construct meaning in their social tags. The collection of works used to search for social tags came from the Association of College and Research Libraries’ list on East Asian, South and Southeast Asian, and Middle Eastern women. A pilot study was conducted comprising of a limited sample in each of the three domains, which helped generate a framework of analysis that was used in application for the larger sample of works on Asian women. The full study analyzed 1231 social tags collected from 122 works on Asian women. Findings from this study showed that users construct a variety of intersections relating to gender and ethnicity for works on Asian women. Overall findings from this showed that gender and gender-related constructs were the most common subject of tags employed for works on Asian women. Users more often referred to geography rather than ethnicity when describing the materials on Asian women. Interesting themes to emerge involved how gender and other constructs differed among the three domains. Tags describing the majority of East Asia, such as Chinese and Japanese were most common in the East Asian dataset. Countries not considered the “majority” in South and Southeast Asia were often used, such as Indonesia and the Philippines. Themes of sexuality and religion were much more prevalent in the Middle Eastern set of tags. Social tags act as a mechanism for social commentary. Researchers have access to a plethora of constructions available to them through these social tags; such abundance of information is a valuable resource to understanding how the general populace understands intersections and constructs identity

Integration of distributed terminology resources to facilitate subject cross-browsing for library portal systems

With the increase in the number of distributed library information resources, users may have to interact with different user interfaces, learn to switch their mental models between these interfaces, and familiarise themselves with controlled vocabularies used by different resources. For this reason, library professionals have developed library portals to integrate these distributed information resources, and assist end-users in cross-accessing distributed resources via a single access point in their own library. There are two important subject-based services that a library portal system might be able to provide. The first is a federated search service, which refers to a process where a user can input a query to cross-search a number of information resources. The second is a subject cross-browsing service, which can offer a knowledge navigation tree to link subject schemes used by distributed resources. However, the development of subject cross-searching and browsing services has been impeded by the heterogeneity of different KOS (Knowledge Organisation System) used by different information resources. Due to the lack of mappings between different KOS, it is impossible to offer a subject cross-browsing service for a library portal system. [Continues.

Design of a Controlled Language for Critical Infrastructures Protection

We describe a project for the construction of controlled language for critical infrastructures protection (CIP). This project originates from the need to coordinate and categorize the communications on CIP at the European level. These communications can be physically represented by official documents, reports on incidents, informal communications and plain e-mail. We explore the application of traditional library science tools for the construction of controlled languages in order to achieve our goal. Our starting point is an analogous work done during the sixties in the field of nuclear science known as the Euratom Thesaurus.JRC.G.6-Security technology assessmen
