Basic XML and RDF techniques for knowledge management


“This column, the third in a series, shows how to add semantic knowledge to an RDF application by incorporating WordNet synonym sets. With the added knowledge of the WordNet lexical database, you can search a set of RDF data for related concepts, not just one keyword at a time. As the demonstration issue-tracker application shows, that means searching once for instances that fit within the concept of “selection” rather than searching individually on “vote,” “choice,” “ballot,” and 86 other related terms. Columnist Uche Ogbuji’s sample code in Python illustrates the techniques.”
