Fascinated with the most recent study on textual content and record administration, this consultant addresses the knowledge administration wishes of organisations through supplying the latest findings. How the necessity for powerful databases to deal with details is impacting agencies all over the world and the way a few organisations that own an unlimited quantity of information can not use the information in an fiscal and effective demeanour is confirmed. A taxonomy for object-oriented databases, metrics for controlling database complexity, and a consultant to accommodating hierarchies in relational databases are supplied. additionally lined is find out how to observe Java-triggers for X-Link administration and the way to construct signatures.

Get Syntax-Directed Semantics: Formal Models Based on Tree PDF

The topic of this publication is the research of tree transducers. Tree trans­ ducers have been brought in theoretical laptop technology with a purpose to research the final houses of formal types which offer semantics to context-free languages in a syntax-directed method. Such formal versions comprise characteristic grammars with synthesized attributes purely, denotational semantics, and at­ tribute grammars (with synthesized and inherited attributes).

F. de Sousa Universidade Federal de Campina Grande, Brazil ABSTRACT With the growing significance of digital libraries and the Internet, more and more electronic texts become accessible to a wide and geographically disperse public. This requires adequate tools to facilitate indexing, storage and retrieval of documents written in different languages. We present a method for semi-automatic indexing of electronic documents and construction of a multilingual thesaurus, which can be used for query formulation and information retrieval.

The documents are indexed and the extracted terms are converted to a languageneutral thesaurus (called multilingual thesaurus). The same occurs with the query, and the correspondence between query terms and documents is obtained via the neutral thesaurus. The first solution is the most widely used in the Cross-Language Information Retrieval (CLIR) community (Go02; Ogden & Davis, 2000; Oard, 1999). It applies also to other information retrieval environments, such as the World Wide Web. For digital libraries, with thousands of documents, indexing of incoming documents and a good association structure between index terms and documents can become crucial for efficient document retrieval.
