Discussion of image database systems focuses on semantic queries and shows how an image is abstracted into a hierarchy of entity names and features; how relations are established between entities visible in the image; and how a "fuzzy" matching technique is used to compare semantic queries to image abstractions.

Discussion of the use of information retrieval techniques for automatic generation of semantic hypertext links focuses on automatic text summarization. Topics include World Wide Web links, text segmentation, and evaluation of text summarization by comparing automatically generated abstracts with manually prepared abstracts. (Author/LRW)

Analyzes features of the Swedish language from the viewpoint of mono-and cross-language information retrieval. Results of a comparative study that tested the degree of lexical ambiguity in Swedish, Finnish, and English suggest that part-of-speech tagging might be useful in Swedish information retrieval due to the high frequency of homographic…

Presents two methods for evaluating automatically generated hypertext links: one is based on correlations between shortest paths in the hypertext structure and a semantic similarity measure, and the other is based on measuring users' performances using hypertext. Advantages and disadvantages of computer versus human evaluation are discussed.…
