    Abstract
    This article provides an overview of recent developments relating to the application of thesauri in information organisation and retrieval on the World Wide Web. It describes some recent thesaurus projects undertaken to facilitate resource description and discovery and access to wide-ranging information resources on the Internet. Types of thesauri available on the Web, thesauri integrated in databases and information retrieval systems, and multiple-thesaurus systems for cross-database searching are also discussed. Collective efforts and events in addressing the standardisation and novel applications of thesauri are briefly reviewed.

    Abstract
    The World Wide Web and the use of HTML-based information displays has greatly increased access to online information sources, but at the same time limits the ways in which they can be used. By the same token, Web-based indexing and search engines give us access to the full text of online documents, but make it difficult to access them in any kind of organized, systematic way. For years before the advent of the Internet, lexicographers built weIl-structured subject thesauri to organize large collections of documents. These have since been converted into electronic form and even put online, but in ways that are largely uncoordinated and not useful for searching. This paper describes some of the ways in which XML-based Web services could be used to coordinate subject thesauri and other online vocabulary sources to create a "Thesauro-Web" that could be used by both searchers and indexers to improve subject access an the Internet.

    Abstract
    The latest thesaurus guidelines, ISO 2788 and ANSI/NISO Z39.19-1993, were published before many recent changes in the nature of databases, and before the full impact of the Internet on information storage and retrieval. The major changes are addressed in light of implications for reconsideration and possible revision of the guidelines

    Abstract
    The information retrieval thesaurus emerged in the 1950s, settled down to a more-or-less standard format in the 1970s and has continued to evolve marginally since then. Throughout its whole lifetime, doubts have been expressed about its efficacy with emphasis latterly on cost-effectiveness. Prolonged testing of different styles of index language in the 1970s failed to settle the doubts. The arena occupied by the debate has moved from small isolated databases in the post-war era to diverse situations nowadays with the whole Internet at one extreme and small in-house collections at the other. Sophisticated statistical techniques now dominate the retrieval landscape on the Internet but leave opportunities for the thesaurus and other knowledge organization techniques in niches such as image libraries and corporate intranets. The promise of an ontology-driven semantic web with linked data resources opens another opportunity. Thus much scope remains for research to establish the usefulness of the thesaurus in these places and to inspire its continuing evolution.

    Abstract
    Thesauri have triumphed in many domains that require precise and exhaustive information because of their representational power, their capability to integrate the concept-based and alphabetical approaches to organizing information, and their standardization and, more recently, formalization. Nevertheless, there is room to improve their relevance in the digital age by embracing the open linked data initiatives and by taking advantage of their structural and functional proximity to some of the big collaborative knowledge repositories in the Internet, notably the Wikipedia environment. With a focus on its implications for enhanced interoperability, this structural proximity is analysed, and the benefits of such collaboration for the different potential stakeholders are considered. It is proposed that better devices for ensuring semantic browsing are provided when necessary, and that an open hub for thesauri interconnection is developed, perhaps using existing big open Internet semantic facilities, such as Wikipedia.

    Abstract
    The current standards for monolingual and multilingual thesauri are long overdue for an update. This applies to the international standards ISO 2788 and ISO 5964, as well as the corresponding national standards in several countries and the American standard ANSI/NISO Z39.19. Work is now under way in the UK and in the USA to revise and extend the standards, with particular emphasis on interoperability needs in our world of vast electronic networks. Work in the UK is starting with the British Standards, in the hope of leading on to one international standard to serve all. Some of the issues still under discussion include the treatment of facet analysis, coverage of additional types of controlled vocabulary such as classification schemes, taxonomies and ontologies, and mapping from one vocabulary to another. 1. Are thesaurus standards still needed? Since the 1960s, even before the renowned Cranfield experiments (Cleverdon et al., 1966; Cleverdon, 1967) arguments have raged over the usefulness or otherwise of controlled vocabularies. The case has never been proved definitively one way or the other. At the same time, a recognition has become widespread that no one search method can answer all retrieval requirements. In today's environment of very large networks of resources, the skilled information professional uses a range of techniques. Among these, controlled vocabularies are valued alongside others. The first international standard for monolingual thesauri was issued in 1974. In those days, the main application was for postcoordinate indexing and retrieval from document collections or bibliographic databases. For many information professionals the only practicable alternative to a thesaurus was a classification scheme. And so the thesaurus developed a strong following. After computer systems with full text search capability became widely available, however, the arguments against controlled vocabularies gained more followers. The cost of building and maintaining a thesaurus or a classification scheme was a strong disincentive. Today's databases are typically immense compared with those three decades ago. Full text searching is taken for granted, not just in discrete databases but across all the resources in an intranet or even the Internet. But intranets have brought particular frustration as users discover that despite all the computer power, they cannot find items which they know to be present an the network. So the trend against controlled vocabularies is now being reversed, as many information professionals are turning to them for help. Standards to guide them are still in demand.

    Abstract
    Thesauri have been important information and knowledge organisation tools for more than three decades. The recent emergence and phenomenal growth of the World Wide Web has created new opportunities to introduce thesauri as information search and retrieval aids to end user communities. While the number of web-based and hypertextual thesauri continues to grow, few investigations have yet been carried out to evaluate how end-users, for whom all these efforts are ostensibly made, interact with and make use of thesauri for query building and expansion. The present paper reports a pilot study carried out to determine the extent to which a thesaurus-enhanced search interface to a web-based database aided end-users in their selection of search terms. The study also investigated the ways in which users interacted with the thesaurus structure, terms, and interface. Thesaurusbased searching and browsing behaviours adopted by users while interacting with the thesaurus-enhanced search interface were also examined. 1. Introduction The last decade has witnessed the emergence of a broad range of applications for knowledge structures in general and thesauri in particular. A number of researchers have predicted that thesauri will increasingly be used in retrieval rather than for indexing (Milstead, 1998; Aitchison et al., 1997) and that their application in information retrieval systems will become more diverse due to the growth of fulltext databases accessed over the Internet (Williamson, 2000). Some researchers have emphasised the need for tailoring the structure and content of thesauri as tools for end-user searching (Bates, 1986; Strong and Drott, 1986; Anderson and Rowley, 1991; Lopez-Huertas, 1997) while others have suggested thesaurus-enhanced user interfaces to support query formulation and expansion (Pollitt et.al., 1994; Jones et.al., 1995; Beaulieu, 1997). The recent phenomenal growth of the World Wide Web has created new opportunities to introduce thesauri as information search and retrieval aids to end user communities. While the number of web-based and hypertextual thesauri continues to grow, few investigations have been carried out to evaluate the ways in which end-users interact with and make use of online thesauri for query building and expansion. The work reported here expands an a pilot study (Shiri and Revie, 2001) carried out to investigate user - thesaurus interaction in the domains of biology and veterinary medicine.
