QUERY PROCESSOR, QUERY PROCESSOR ELEMENTS AND A METHOD OF ESTABLISHING SUCH A QUERY PROCESSOR AND QUERY PROCESSOR ELEMENTS AND A DOMAIN PROCESSOR

摘要

The invention relates to a domain processor (DP) comprising: at least one robot modeller (RM); at least one domain modeller (DMR); at least one Query Processor Modeller (QPM), said robot modeller (RM) comprising: means for modelling at least one computer-based robot (R); said at least one robot (R) being adapted for accessing at least one web-based data source (DS); said at least data source (DS) comprising entities comprised in a predefined domain (D); said at least one domain modeller (DMR) comprising: means for modelling at least one domain model (DM); means for establishing at least one extraction model (EM) associated with a chosen domain; means for establishing at least one storage model (STM) associated with said chosen domain, said at least one Query Processor Modeller (QPM) comprising: means for selecting at least two Query Processor elements (QPE) from a set of predefined query processor elements (QPE); means for combining at least two of the selected Query Processor elements (QPE); means for executing said associated query processor elements on at least one computer system (CS); at least one of said query processor elements (QPE) of the associated query processor elements being a Robot query processor Elemet (RQPE) adapted for accessing at least one web-based data source (DS).
