Abstract :
Nowadays finding relevant information on the World Wide Web (WWW) is often a frustrating task, due to its unstructured nature and the limitations of existing search engines. In this paper, we introduce a schema model for querying the web data which have been used in a specific-domain web data engine - SESQ. This model uses an ontology-based method for modeling the Web data, and employs the directed- labeled multi-graph as concept schema for describing the web data of a specific domain at a high abstract level. Users can easily express their query requests with an SQL-like query language over a tree-structure view schema which could be defined based on their real query intent. Underlying schema will help system to organize the data extracted from web and give a logical view to upper components of SESQ.
