    Abstract
    The Alexandria Digital Library Project announces the online publication of two protocols to support querying and response interactions using distributed services: one for gazetteers and one for thesauri. These protocols have been developed for our own purposes and also to support the general interoperability of gazetteers and thesauri on the web. See <http://www.alexandria.ucsb.edu/~gjanee/gazetteer/> and <http://www.alexandria.ucsb.edu/~gjanee/thesaurus/>. For the gazetteer protocol, we have provided a page of test forms that can be used to experiment with the operational functions of the protocol in accessing two gazetteers: the ADL Gazetteer and the ESRI Gazetteer (ESRI has participated in the development of the gazetteer protocol). We are in the process of developing a thesaurus server and a simple client to demonstrate the use of the thesaurus protocol. We are soliciting comments on both protocols. Please remember that we are seeking protocols that are essentially "simple" and easy to implement and that support basic operations - they should not duplicate all of the functions of specialized gazetteer and thesaurus interfaces. We continue to discuss ways of handling various issues and to further develop the protocols. For the thesaurus protocol, outstanding issues include the treatment of multilingual thesauri and the degree to which the language attribute should be supported; whether the Scope Note element should be changed to a repeatable Note element; the best way to handle the hierarchical report for multi-hierarchies where portions of the hierarchy are repeated; and whether support for searching by term identifiers is redundant and unnecessary given that the terms themselves are unique within a thesaurus. For the gazetteer protocol, we continue to work on validation of query and report XML documents and on implementing the part of the protocol designed to support the submission of new entries to a gazetteer. We would like to encourage open discussion of these protocols through the NKOS discussion list (see the NKOS webpage at <http://nkos.slis.kent.edu/>) and the CGGR-L discussion list that focuses on gazetteer development (see ADL Gazetteer Development page at <http://www.alexandria.ucsb.edu/gazetteer>).

    The objective of this research was to investigate the extent to which thesauri have the potential to support the search behaviour of nanoscience and technology researchers while interacting with an electronic book digital library. Transaction log data was obtained from a nanoscience and technology digital library to investigate the nature, type and characteristics of users' queries and search terms. The specific objectives was to assess the extent to which users' search terms matched with those found in two well-established thesauri attached o the INSPEC and Compendex databases.

    Abstract
    Purpose - Seeks to share with digital library practitioners the development process of an online image collection that integrates the syndetic structure of a controlled vocabulary to improve end-user search and browse functionality. Design/methodology/approach - Surveys controlled vocabulary structures and their utility for catalogers and end-users. Reviews research literature and usability findings that informed the specifications for integration of the controlled vocabulary structure into search and browse functionality. Discusses database functions facilitating query expansion using a controlled vocabulary structure, and web application handling of user queries and results display. Concludes with a discussion of open-source alternatives and reuse of database and application components in other environments. Findings - Affirms that structured forms of browse and search can be successfully integrated into digital collections to significantly improve the user's discovery experience. Establishes ways in which the technologies used in implementing enhanced search and browse functionality can be abstracted to work in other digital collection environments. Originality/value - Significant amounts of research on integrating thesauri structures into search and browse functionalities exist, but examples of online resources that have implemented this approach are few in comparison. The online image collection surveyed in this paper can serve as a model to other designers of digital library resources for integrating controlled vocabularies and metadata structures into more dynamic search and browse functionality for end-users.

    Abstract
    In this demonstration we present a visual analysis approach that addresses both developers and users of hierarchical classification systems. The approach supports an intuitive understanding of the structure and current use in relation to a specific collection. We will also demonstrate its application for the development and management of library collections.

    Abstract
    The MACS (Multilingual access to subjects) project is one of the many projects that are currently exploring solutions to multilingual subject access to online catalogs. Its strategy is to develop a Web based link and search interface through which equivalents between three Subject Heading Languages: SWD/RSWK (Schlagwortnormdatei/Regeln für den Schlagwortkatalog) for German, RAMEAU (Repertoire d'Autorite-Matière Encyclopedique et Alphabetique Unifie) for French and LCSH (Library of Congress Subject Headings) for English can be created and maintained, and by which users can access online databases in the language of their choice. Factors that have lead to this approach will be examined and the MACS linking strategy will be explained. The trend to using mapping or linking strategies between different controlled vocabularies to create multilingual access challenges the traditional view of the multilingual thesaurus.

    Abstract
    The need for Persian thesauri became apparent during the late 1960s with the advent of documentation centres in Iran. The first Persian controlled vocabulary was published by IRANDOC in 1977. Other centres worked on translations of existing thesauri, but it was soon realised that these efforts did not meet the needs of the centres. After the Islamic revolution in 1979, the foundation of new centres intensified the need for Persian thesauri, especially in the fields of history and government documents. Also, during the Iran-Iraq war, Iranian research centres produced reports in scientific and technical fields, both to support military requirements and to meet society's needs. In order to provide a comprehensive thesaurus, the Council of Scientific Research of Iran approved a project for the compilation of such a work. Nowadays, 12 Persian thesauri are available and others are being prepared, based on the literary corpus and conformity with characteristics of Iranian culture.

    Abstract
    For the sake of national security, very large volumes of data and information are generated and gathered daily. Much of this data and information is written in different languages, stored in different locations, and may be seemingly unconnected. Crosslingual semantic interoperability is a major challenge to generate an overview of this disparate data and information so that it can be analyzed, shared, searched, and summarized. The recent terrorist attacks and the tragic events of September 11, 2001 have prompted increased attention an national security and criminal analysis. Many Asian countries and cities, such as Japan, Taiwan, and Singapore, have been advised that they may become the next targets of terrorist attacks. Semantic interoperability has been a focus in digital library research. Traditional information retrieval (IR) approaches normally require a document to share some common keywords with the query. Generating the associations for the related terms between the two term spaces of users and documents is an important issue. The problem can be viewed as the creation of a thesaurus. Apart from this, terrorists and criminals may communicate through letters, e-mails, and faxes in languages other than English. The translation ambiguity significantly exacerbates the retrieval problem. The problem is expanded to crosslingual semantic interoperability. In this paper, we focus an the English/Chinese crosslingual semantic interoperability problem. However, the developed techniques are not limited to English and Chinese languages but can be applied to many other languages. English and Chinese are popular languages in the Asian region. Much information about national security or crime is communicated in these languages. An efficient automatically generated thesaurus between these languages is important to crosslingual information retrieval between English and Chinese languages. To facilitate crosslingual information retrieval, a corpus-based approach uses the term co-occurrence statistics in parallel or comparable corpora to construct a statistical translation model to cross the language boundary. In this paper, the text based approach to align English/Chinese Hong Kong Police press release documents from the Web is first presented. We also introduce an algorithmic approach to generate a robust knowledge base based an statistical correlation analysis of the semantics (knowledge) embedded in the bilingual press release corpus. The research output consisted of a thesaurus-like, semantic network knowledge base, which can aid in semanticsbased crosslingual information management and retrieval.

    Abstract
    This paper describes the Laurin thesaurus, which is used for indexing and searching in the Laurin system, a software package for digital clipping archives. As a multilingual thesaurus it complies with the corresponding standards, though presenting some approaches going beyond some of the standards' recommendations. The Laurin thesaurus integrates all kind of indexing terms, not only keywords, but proper names as well. The system of categories and relationships is described in detail.

    Abstract
    The amount of work to be done in rendering the digital information space more efficient and effective has attracted a wide range of disciplines which, in turn, has given rise to a degree of confusion in the terminology applied to information problems. This note seeks to shed some light on the three terms thesauri, taxonomies and ontologies as they are currently being used by, among others, information scientists, AI practitioners, and those working on the foundations of the semantic Web. The paper is not a review of the techniques themselves.

    Abstract
    For years, Mexico has had a distance learning system backed by television-signal-transmitted videos. The change to digital and computer transmission demands organizing the information system and its subject contents through a thesaurus. To prepare the thesaurus, an evaluation of existing thesauri and standards for data exchange was carried out, aimed at retrieving subject contents and scheduling broadcasting. Methodology for evaluating thesauri was proposed, compared with a virtual educational platform and a basic structure for setting up the information system was recommended.

    Abstract
    This paper describes the procedures for a concept-based mapping of two agricultural thesauri, the multilingual AGROVOC, created and maintained by the Food and Agricultural Organization, and the bilingual Chinese Agricultural Thesaurus, created and maintained by the Chinese Academy of Agricultural Science. Conducted under the auspices of FAO's Agricultural Ontology Service, the mapping project aims to extend AGROVOC with an additional set of perspectives on the agricultural domains, enrich its domain and language coverage, and make use of AGROVOC as a common data model for data exchange among a wide range of multilingual repositories within agriculture.

    Abstract
    This paper describes an ongoing project in which the subject headings contained in twelve controlled vocabularies covering multiple disciplines from the humanities to the sciences and including law and education among others are being collapsed into a single vocabulary and reference structure. The design of the database, algorithms created to programmatically link like-concepts, and daily maintenance are detailed. The problems and pitfalls of dealing with multiple vocabularies are noted, as well as the difficulties in relying purely an computer generated algorithms. The application of this megathesaurus to bibliographic records and methodology of retrieval is explained.
