- Abstract
- This paper reviews the enormous changes in cataloging and classification reflected in the literature of 2003 and 2004, and discusses major themes and issues. Traditional cataloging and classification tools have been re-vamped and new resources have emerged. Most notable themes are: the continuing influence of the Functional Requirements for Bibliographic Control (FRBR); the struggle to understand the ever-broadening concept of an "information entity"; steady developments in metadata-encoding standards; and the globalization of information systems, including multilinguistic challenges.

- Abstract
- This is the fourth in a series of papers on classification based on phenomena instead of disciplines. Together with types, levels and facets that have been discussed in the previous parts, themes and rhemes are further structural components of such a classification. In a statement or in a longer document, a base theme and several particular themes can be identified. Base theme should be cited first in a classmark, followed by particular themes, each with its own facets. In some cases, rhemes can also be expressed, that is new information provided about a theme, converting an abstract statement ("wolves, affected by cervids") into a claim that some thing actually occurs ("wolves are affected by cervids"). In the Integrative Levels Classification rhemes can be expressed by special deictic classes, including those for actual specimens, anaphoras, unknown values, conjunctions and spans, whole universe, anthropocentric favoured classes, and favoured host classes. These features, together with rules for pronounciation, make a classification of phenomena a true language, that may be suitable for many uses.

- Abstract
- The paper presents a coword-analysis-based system called SDOC which is able to pupport the intellectual work of an end-user who is searching for information in a bibliographic database. This is done by presenting its thematical structure as a map of keyword clusters (themes) on a graphical user interface. These mapping facilities are demonstrated on the basis of the research field Social History given by a set of documents from the social science literature database SOLIS. Besides the traditional way of analysing a coword map as a strategic diagram, the notion of cluster relationships analysis is introduced which provides an adequate interpretation of links between themes

- Abstract
- This paper presents an approach for integrating multiple sources of semantics for the creating metadata. A new framework is proposed to define topics and themes with both manually and automatically generated terms. The automatically generated terms include: terms from a semantic analysis of the collections and terms from previous user's queries. An interface is developed to facilitate the creation and use of such topics and themes for metadata creation. The framework and the interface promote human-computer collaboration in metadata creation. Several principles underlying such approach are also discussed.

- Abstract
- For information retrieval in the Chinese language, 3 representation methods for texts are popular, namely: 1-gram or character, bigram, and short-word. Each has its advantages as well as drawbacks. Employing more than one method may combine advantages from them and enhance retrieval effectiveness. We investigated 2 ways of using them simultaneously: mixing representations in documents and queries, and combining retrieval lists obtained via different representations. The experiments were done with the 170 MB evaluated Chinese corpora and 54 long and short queries available from the TREC program and using our Probabilistic Indexing and Retrieval Components System (PIRCS retrieval system). Experiments show that good retrieval need not depend on accurate word segmentation; approximate segmentation into short-words will do. Results also show and confirm that bigram representation alone works well; mixing characters with bigram representation boosts effectiveness further, but it is preferable to mix characters with short-word indexing which is more efficient, needs less resource, and gives better retrieval more often. Cobining retrieval lists from short-word with character representation and from bigram indexing provides the best retrieval results but also at a substabtial cost

- Abstract
- The UK has not followed other countries in developing framworks of policies to guide their transition into information societies in a consistent and systematic way. Analyzes the current UK policies using a matrix which identifies 3 levels of policy (industrial, organization and social) and 4 cross cutting themes (information technology, information markets, human resources and legislation and regulation). Concludes that together, these various initiatives add up to a national strategy but it is one that lacks coordination and cohesion

- Abstract
- Building on the approach of Sir Ernest Gombrich, seven basic functions or goals of art are outlined as a new framework for the classification of fine art and visual images: connecting, ordering, matching, systematizing, mixing, internalizing and externalizing. It is suggested why only the first two of these goals, connecting and ordering, tend to produce closed repertoires of images, whereas the other goals stimulate open repertoires of images. A chief reason for these open repertoires was found in an interplay between visualization and verbalization which increased with the advent of printing

- Abstract
- We analyze the large-scale structure of the journal citation network built from information contained in the Thomson-Reuters Journal Citation Reports. To this end, we explore network properties such as density, percolation robustness, average and largest node distances, reciprocity, incoming and outgoing degree distributions, and assortative mixing by node degrees. We discover that the journal citation network is a dense, robust, small, and reciprocal world. Furthermore, in- and outdegree node distributions display long tails, with few vital journals and many trivial ones, and they are strongly positively correlated.

- Abstract
- Mixed methods research (MMR) has been described as the third research paradigm that combines qualitative and quantitative research methods. The mixing of research methods requires an epistemological framework that embraces the "reality" uncovered by different research methods. Three formal ontological categories are introduced for deconstructing the polarized view of reality in objectivism and relativism and for differentiating the nature and characteristics of objective, subjective, and normative validity claims as well as the conditions for justifying "objectivity" in social research. The characterization of "information" as objective, subjective, and normative-evaluative simultaneously demands the study of conditions of information-related phenomena that may call for mixed methods research in library and information science.

- Abstract
- The digital library is a socio-technical concept of great significance. It redefines the relationships between information providers and intermediaries and, potentially, transforms the way that services are delivered to users. This article, based on a British Library Research & Innovation Centre funded study, reviews current themes and directions in digital library research and scholarship. It locates the digital library in a simple work-oriented framework emphasising its social as well as its systems and informational dimensions. The article highlights differences in understanding of the digital library construct between the library and computer science communities and identifies some critical areas for further research.

- Abstract
- TREC topic specification statements 1-50 are converted to a similarity matrix, scaled, and plotted. 2 close topics and 2 distant topics are selected from within the topic visual field. Subsequent scaling and visualization of documents associated with the close topics reveals a strong mixing of documents from both topic sets. Scaling and visualization of documents associated with the distant topics reveals a bifurcated distribution of documents from both topic sets. Relevant documents in both cases present near the center of both visualizations. Scaling and visualization of documents by multidimensional scaling using a maximum likelihood estimation method is shown to accurately model token similarity relationships among topic specification statements. The implications of these findings for prior critical arguments regarding IR test collections generally, and TREC specifically, by othe scholars is examined

- Abstract
- Some of the problems in the cataloging of Arabic script materials are due to the peculiarities of Arabic books not generally found in European or American imprints, such as the lack of a chief source of information, missing date of publication, mixing up the term impression with edition, etc. Other problems result from the difficulties in determining the form of Arabic personal and corporate names, lack of standard Arabic subject headings, poor coverage of Islamic and Arabic literature, history, culture, customs, and religion in Western classification systems, limitation of the MARC format in dealing with the requirements of Arabic script materials, and the lower standard of cataloging education and training. The paper discusses all of these problems in detail and highlights various attempts, both successful and unsuccessful, made to resolve them.

- Abstract
- Evolving from database models using punch cards, strict linear relational databases and predefined object-oriented data structures, the triple statements underlying Semantic Web technologies bypass many design constraints to offer endless flexibility. Overcoming structure is challenging, especially the relatively recent structure formalized in the Functional Requirements for Bibliographic Records (FRBR). Though geared to easier access and interoperability and recognizing a multilevel bibliographic model, FRBR remains tied to translating entity-relation diagrams to data structures. Resource Description Framework (RDF) provides a more flexible way to express concepts, in which bibliographic models may be thought of as graphs of properties and relationships. But even RDF-based models can undermine that flexibility by mixing concept classes and data structures. The advantage of RDF classes is to provide semantics that enable a user to focus on similarities, not bound by contextual constraints.and success metrics.
