METHOD FOR DETECTION OF OBJECT POSITION IN STORAGE REPOSITORY USING SEARCH SUBJECT CRITERION Russian patent published in 1998 - IPC

FIELD: computer engineering, in particular, information retrieval, databases. SUBSTANCE: method involves building a limited list of keywords for each object, setting object address, filling corresponding fields in information carrier with elements of this list using object address, information is read by corresponding reading unit. When subject search is performed, method involves generation of search subject query, filling information carrier, which is analogous to information carrier with field of object addresses, with this query represented as subject search instruction, reading search subject instruction from information carrier, comparison of words of search subject instruction with field titles which are filled in field of information carriers which are read by corresponding reading unit, and detection of object address by means of these comparisons. Preliminary Ontology is developed and universal information retrieval language is designed. Lexical items of this language are categories of Ontology. Each meaning of each category in Ontology is assigned universal unique code, array of descriptors of universal information retrieval language is generated. Information words list about each object is enriched with maximal list of information words which describe this object according to which corresponding region of Ontology is assigned to given object. Keywords which are detected for this object and implied by corresponding region of Ontology are encoded by means of arrays of descriptors. Then subject-sensitive code description of object with address as its search subject description is entered on corresponding information carrier as whole record. When subject search instruction is entered, all keywords of subject search request are encoded by means of descriptors of universal information retrieval language. EFFECT: increased recall of subject search. 3 cl, 2 dwg
