This paper presents a method of information harvesting and consolidation to support the multilingual information requirements for cross-language information retrieval within digital library systems. We describe a way to create both customized bilingual dictionaries and multilingual query mappings from a source language to many target languages. We will describe a multilingual conceptual mapping resource with broad coverage (over 100 written languages can be supported) that is truly multilingual as opposed to bilingual parings usually derived from machine translation. This resource is derived from the 10+ million title online library catalog of the University of California. It is created statistically via maximum likelihood associations from word and phrases in book titles of many languages to human assigned subject headings in English. The 150,000 subject headings can form interlingua mappings between pairs of languages or from one language to several languages. While our current demonstration prototype maps between ten languages (English, Arabic, Chinese, French, German, Italian, Japanese, Portuguese, Russian, Spanish), extensions to additional languages are straightforward. We also describe how this resource is being expanded for languages where linguistic coverage is limited in our initial database, by automatically harvesting new information from international online library catalogs using the Z39.50 networked library search protocol (AU) |

The Resource Description Framework (RDF) is an infrastructure that enables the encoding, exchange and reuse of structured metadata. RDF is an application of XML that imposes needed structural constraints to provide unambiguous methods of expressing semantics. RDF additionally provides a means for publishing both human-readable and machine-processable vocabularies designed to encourage the reuse and extension of metadata semantics among disparate information communities. The structural constraints RDF imposes to support the consistent encoding and exchange of standardized metadata provides for the interchangeability of separate packages of metadata defined by different resource description communities (AU) |

The Role of Content Analysis in Evaluating Metadata for the U.S. Government Information Locator Service (GILS): Results from an Exploratory Study. |

This paper discusses application of qualitative and quantitative content analysis techniques to assess metadata records from 42 Federal agencies' implementation of the Government Information Locator Service (GILS). GILS databases respond to a late-1994 initiative to "identify public information resources throughout the Federal government, describe the information available in those resources, and provide assistance in obtaining the information [and] serve as a tool to improve agency electronic records management practices". GILS metadata records describe agencies' automated information systems, Privacy Act systems of records, and locators that cover its information dissemination products. The authors used record content analysis, and several other methods, to examine whether GILS is helping agencies fulfill information dissemination and management responsibilities and the extent to which GILS is meeting user expectations. Criteria used in the current analysis were informed in part by results of user and service-implementor questionnaires and focus groups. The record content analysis itself, in turn, informed creation of a scripted online assessment for users, and data from that user assessment supplemented results of the content analysis. The quality of metadata for networked resources is as of yet a relatively unexplored research area. At this point, no consensus has been reached on operational and conceptual definitions of quality; likewise, validated procedures for assessing metadata are lacking. On the basis of the exploratory analysis described here, the authors conclude that a range of criteria and procedures may be needed for different types of metadata (e.g., descriptive, transactional, etc.). In addition to supporting the larger evaluation study of GILS, the results of this analysis of metadata content will contribute to a developing dialog about assessing the quality of metadata. (AU) |
