Abstract

This book constitutes the refereed proceedings of the 7th European Conference on Research and Advanced Technology for Digital Libraries, ECDL 2003, held in Trondheim, Norway in August 2003. The 39 revised full papers and 8 revised short papers presented were carefully reviewed and selected from 161 submissions. The papers are organized in topical sections on uses, users, and user interfaces; metadata applications; annotation and recommendation; automatic classification and indexing; Web technologies; topical crawling and subject gateways; architectures and systems; knowledge organization; collection building and management; information retrieval; digital preservation; and indexing and searching of special documents and collection information.

Abstract

Knowledge Organization Systems can comprise thesauri and other controlled lists of keywords, ontologies, classification systems, clustering approaches, taxonomies, gazetteers, dictionaries, lexical databases, concept maps/spaces, semantic road maps, etc. These schemas enable knowledge structuring and management, knowledge-based data processing and systematic access to knowledge structures in individual collections and digital libraries. Used as interactive information services on the Internet they have an increased potential to support the description, discovery and retrieval of heterogeneous information resources and to contribute to an overall resource discovery infrastructure

Footnote

Relational database Management systems have been one of the great success stories of recent times and sensitive to the market, Most major vendors have responded by extending their products to handle XML data while still exploiting the range of facilities that a modern RDBMS affords. No book of this type would be complete without consideration of the "big these" (Oracle 9i, DB2, and SQL Server 2000 which each get a dedicated chapter) and though occasionally overtly piece-meal and descriptive the authors all note the shortcomings as well as the strengths of the respective systems. This part of the book is somewhat dichotomous, these chapters being followed by two that propose detailed solutions to somewhat theoretical problems, a generic architecture for storing XML in a RDBMS and using an object-relational approach to building an XML repository. The biography of the author of the latter (Paul Brown) contains the curious but strangely reassuring admission that "he remains puzzled by XML." The first five components are in-depth case studies of XMLdatabase applications. Necessarily diverse, few will be interested in all the topics presented but I was particularly interested in the first case study an bioinformatics. One of the twentieth century's greatest scientific undertakings was the Human Genome Project, the quest to list the information encoded by the sequence of DNA that makes up our genes and which has been referred to as "a paradigm for information Management in the life sciences" (Pearson & Soll, 1991). After a brief introduction to molecular biology to give the background to the information management problems, the authors turn to the use of XML in bioinformatics. Some of the data are hierarchical (e.g., the Linnaean classification of a human as a primate, primates as mammals, mammals are all vertebrates, etc.) but others are far more difficult to model. The Human Genome Project is virtually complete as far as the data acquisition phase is concerned and the immense volume of genome sequence data is no longer a very significant information Management issue per se. However bioinformaticians now need to interpret this information. Some data are relatively straightforward, e.g., the positioning of genes and sequence elements (e.g., promoters) within the sequences, but there is often little or no knowledge available an the direct and indirect interactions between them. There are vast numbers of such interrelationships; many complex data types and novel ones are constantly emerging, necessitating an extensible approach and the ability to manage semi-structured data. In the past, object databases such as AceDB (Durbin & Mieg, 1991) have gone some way to Meeting these aims but it is the combination of XML and databases that more completely addresses knowledge Management requirements of bioinformatics. XML is being enthusiastically adopted with a plethora of XML markup standards being developed, as authors Direen and Jones note "The unprecedented degree and flexibility of XML in terms of its ability to capture information is what makes it ideal for knowledge Management and for use in bioinformatics."
