- Abstract
- Zu den großen Herausforderungen einer sinnvollen Suche im WWW gehören die riesige Menge des Verfügbaren und die Sparchbarrieren. Verfahren, die die Web-Ressourcen im Hinblick auf ein effizienteres Retrieval inhaltlich strukturieren, werden daher ebenso dringend benötigt wie Programme, die mit der Sprachvielfalt umgehen können. Im folgenden Vortrag werden wir einige Ansätze diskutieren, die zur Bewältigung der beiden Probleme derzeit unternommen werden

- Abstract
- In order to transfer the Chinese Classified Thesaurus (CCT) into a machine-processable format and provide CCT-based Web services, a pilot study has been conducted in which a variety of selected CCT classes and mapped thesaurus entries are encoded with SKOS. OWL and RDFS are also used to encode the same contents for the purposes of feasibility and cost-benefit comparison. CCT is a collected effort led by the National Library of China. It is an integration of the national standards Chinese Library Classification (CLC) 4th edition and Chinese Thesaurus (CT). As a manually created mapping product, CCT provides for each of the classes the corresponding thesaurus terms, and vice versa. The coverage of CCT includes four major clusters: philosophy, social sciences and humanities, natural sciences and technologies, and general works. There are 22 main-classes, 52,992 sub-classes and divisions, 110,837 preferred thesaurus terms, 35,690 entry terms (non-preferred terms), and 59,738 pre-coordinated headings (Chinese Classified Thesaurus, 2005) Major challenges of encoding this large vocabulary comes from its integrated structure. CCT is a result of the combination of two structures (illustrated in Figure 1): a thesaurus that uses ISO-2788 standardized structure and a classification scheme that is basically enumerative, but provides some flexibility for several kinds of synthetic mechanisms Other challenges include the complex relationships caused by differences of granularities of two original schemes and their presentation with various levels of SKOS elements; as well as the diverse coordination of entries due to the use of auxiliary tables and pre-coordinated headings derived from combining classes, subdivisions, and thesaurus terms, which do not correspond to existing unique identifiers. The poster reports the progress, shares the sample SKOS entries, and summarizes problems identified during the SKOS encoding process. Although OWL Lite and OWL Full provide richer expressiveness, the cost-benefit issues and the final purposes of encoding CCT raise questions of using such approaches.

- Abstract
- The focus of this article is to develop a map display for information retrieval. Through an examination of relationships among visual displays, information retrieval, and browsing, advantages of visual displays for information retrieval are characterized as (1) the ability to convey a large amount of information in a limited space, (2) the potential to reveal semantic relationships of terms and documents; and (3) the facilitation of browsing and perceptual inferences on retrieval interfaces. These advantages are further demonstrated through a map display generated by a neural network's self-organizing algorithm. The map display detects complex relationships among given documents, and reveals the relationships through a spatial arrangement of terms abstracted from the documents. The map display also provides interactive tools to allow the user to interact with the underlying information. Examples of the map displays show that such map displays can be used both as an overview tool and an access or exploration tool, and the map displays will likely increase the amount of information that the user is willing to browse

- Abstract
- MedLine Search Assistant is a new interface for MEDLINE searching. The interface is designed to (1) visualize boolean query building process, (2) extract descriptors (MeSH terms) automatically from the retrieved documents and list them in the order of their occurrence frequencies, (3) guide the user's query modification process through the display of the number of hits, and (4) allow the user to "pick-and-choose" from a list of related MeSH terms to construct search queries. MedLine Search Assistant improves both search precision and recall by helping the user convert a free text search to a controlled vocabulary-based search in a visual environment
