A Rapidly Extensible Language System (The Rel Language Processor)
نویسندگان
چکیده
languages to coexist within a single computer system. Here the term "language" is understood to include a particular data base. New languages may be defined by constructing a new base language with its syntax and semantics, by extending the terminology from a given base level in order to reflect specific concepts, or by associating a given base language with a certain data base. REL consists of an operating environment, a language processor, and the set of currently defined languages. The structural properties of these languages which determine the characterization and organization of the language processor are described. In particular, representation and manipulation of syntax and semantics are discussed, the mechanism of language extension is outlined, and the concept of a generator is introduced.

متن کاملImproved Skips for Faster Postings List Intersection
Information retrieval can be achieved through computerized processes by generating a list of relevant responses to a query. The document processor, matching function and query analyzer are the main components of an information retrieval system. Document retrieval system is fundamentally based on: Boolean, vector-space, probabilistic, and language models. In this paper, a new methodology for mat...
