Demonstrates that hierarchical naming schemes--one with a single namespace and fixed root spread over all machines in a distributed system, and a second with total namespace composed of some aggregation of individual namespaces of each component system's filestores--can coexist in distributed computer systems. Combined system's design is…

Describes how operations on local inverted files are to be modified in order to use them in distributed information retrieval systems based on thesauri. The presented rules may be viewed as the logical approach in implementing a distributed retrieval system consisting of n local retrieval systems. (Author/MBR)

Describes a conceptual Knowledge Representation Language (KRL) developed at the French National Center for Scientific Research, that is used for the construction and use of Large Knowledge Bases (LKBs) and/or Intelligent Information Retrieval Systems (IIRSs). Semantic factors are discussed, and the specialization hierarchies used are explained.…

Discusses origin, scope, objectives, term relationships, updating, and future of "Thesaurus of Common Topics," an interdisciplinary thesaurus being developed by the Polish Centre for Scientific, Technical, and Economic Information as a main source of terms for branch thesauri development for the Polish national System of Scientific,…

Describes the construction (input preparation, computer processing, and presentation) of Classaurus, a vocabulary control tool used for indexing according to the Postulate-based Permuted Subject Indexing (POPSI) language. The efficiency of an online classaurus with facilities for direct accessing and updating is discussed. (MBR)

Describes a collaborative, reuse hypertext system, called MUCH (Many Using and Creating Hypertext). The novel browsing and retrieval characteristics of the system are based on a semantic net connecting documents, thesauri, and discussions. Word patterns are documented for reuse, creating and reorganizing network traversal according to user…
