- Abstract
- In this document we provide an overall view of the state of the art in ontology alignment. It is organised as a description of the need for ontology alignment, a presentation of the techniques currently in use for ontology alignment and a presentation of existing systems. The state of the art is not restricted to any discipline and consider as some form of ontology alignment the work made on schema matching within the database area for instance. Heterogeneity problems on the semantic web can be solved, for some of them, by aligning heterogeneous ontologies. This is illustrated through a number of use cases of ontology alignment. Aligning ontologies consists of providing the corresponding entities in these ontologies. This process is precisely defined in deliverable D2.2.1. The current deliverable presents the many techniques currently used for implementing this process. These techniques are classified along the many features that can be found in ontologies (labels, structures, instances, semantics). They resort to many different disciplines such as statistics, machine learning or data analysis. The alignment itself is obtained by combining these techniques towards a particular goal (obtaining an alignment with particular features, optimising some criterion). Several combination techniques are also presented. Finally, these techniques have been experimented in various systems for ontology alignment or schema matching. Several such systems are presented briefly in the last section and characterized by the above techniques they rely on. The conclusion is that many techniques are available for achieving ontology alignment and many systems have been developed based on these techniques. However, few comparisons and few integration is actually provided by these implementations. This deliverable serves as a basis for considering further action along these two lines. It provide a first inventory of what should be evaluated and suggests what evaluation criterion can be used.

- Abstract
- Nowadays, users of information services are faced with highly decentralised, heterogeneous document sources with different content analysis. Semantic heterogeneity occurs e.g. when resources using different systems for content description are searched using a simple query system. This report describes several approaches of handling semantic heterogeneity used in projects of the German Social Science Information Centre

- Abstract
- Reports results of the 2 studies: "Retrospective conversion of library catalogues in institutions of higher education in the United Kingdom: a study of the justification for a national programme" and "Retrospective conversion for libraries in the UK other than those funded by the Higher Education Funding Councils". The latter study was on behalf of libraries other than national ones: public; learned and scientific society; professional; and religious. Covers: the scale of UK retrospective conversion issues, opportunities and need for a national strategy; retrospective conversion in an international context; conversion of library catalogues in UK higher education institutions; and catalogues in other UK libraries

- Abstract
- An important stage in the process of retrieval of objects from a hypertext database is the creation of a set of internodal links that are intended to represent the relationships existing between objetcs; an operation that is usually undertaken manually such as the allocation of subject index terms to documents. Reports results of a study in which several different sets of hypertext links were inserted, each by a different person, between the paragraphs of each of a number of full text documents. The similarity between the members of each pair of link sets was then evaluated. Results indicated that little similarity existed among the link sets, a finding comparable with those of studies of inter indexer consistency, which suggests that there is generally only a low level of agreemenet between the sets of index terms assigned to a document by indexers. Concludes with that part of the study designed to test the validity of making these kinds of assumptions in the context of hypertext link sets

- Abstract
- State of the art review of hypertext systems in use in UK libraries. Systems include public access point of information (POI) systems that provide guidance to users of local resources, and networked document retrieval systems, such as WWW, that enable users to access texts stored on machines linked by the Internet. Particular emphasis is placed on those systems that are produced inhouse by the libraries in which they are used. The review is based on a series of telephone or face to face interviews conducted with representatives of those organizations that a literature review and mailed questionnaire survey identified as current users of hypertext. Considers issues relating to system development and usability, and presents a set of appropriate guidelines for the designers of future systems. Concludes that: the principle application of hypertext systems in UK libraries is in the implementation of POI systems; that such development is most advanced in the academic sector; and that such development is set to increase in tandem with use of the WWW

- Abstract
- Reports results of a study of the needs of management researchers in relation to their consumption and use of information. A profile of the management researcher was drawn up based on a questionnaire survey of the views of 404 researchers, mostly at PhD level, studying at 53 different institutions in the UK. Results highlighted the importance of periodicals and the English language orientation of researchers, who appear to place little significance on continental European literature as a contribution to the resolution of their research problems

- Abstract
- Summarizes findings of an international study on information-seeking habits and preferences: With extensive input from hundreds of librarians and OCLC staff, the OCLC Market Research team developed a project and commissioned Harris Interactive Inc. to survey a representative sample of information consumers. In June of 2005, we collected over 3,300 responses from information consumers in Australia, Canada, India, Singapore, the United Kingdom and the United States. The Perceptions report provides the findings and responses from the online survey in an effort to learn more about: * Library use * Awareness and use of library electronic resources * Free vs. for-fee information * The "Library" brand The findings indicate that information consumers view libraries as places to borrow print books, but they are unaware of the rich electronic content they can access through libraries. Even though information consumers make limited use of these resources, they continue to trust libraries as reliable sources of information.

- A project to design a graphical user interface for the OKAPI online catalogue search system which uses the basic term weighting probabilistic search engine. Presents a research context of the project with a discussion of interface and functionality issues relating to the design of OPACs. Describes the design methodology and evaluation methodology. Presents the preliminary results of the field trial evaluation. Considers problems encountered in the field trial and discusses contributory factors to the effectiveness of interactive query expansion. Highlights the tension between usability and functionality in highly interactive retrieval and suggests further areas of research

- Abstract
- This short guide describes the process for creating a CD-ROM based üublic access catalog. The authors admit that the material will be outdated by the time of publication, because product specifics change so rapidly. The report is useful, but not completely thorough. Disadvantages to using CD-ROM for public access catalog are listed, but existing methods to overcome these hindrances are not mentioned. The paper also touches on the possibility that CD-ROM-based catalogs may be more than simply an extra service, that they may become full-service catalogs in themselves

- Abstract
- Aims to provide an accurate and comprehensive bibliographic description of Canadian science fiction and fantasy literature in english language pulp magazines published between 1896 and 1955, a fragile and increasingly elusive periodical genre which contains a virtually unknown selection of popular fiction and art by Canadians. The arrangement is alphabetical under the following headings: author index; title index; artist index; magazine index; and series index
