Abstract :
Summary form only given. W3QL is a SQL like, high level language for accessing World-Wide Web (WWW) resident data and services, W3QL is declarative. A W3QL query specifies a graph to be matched with portions of the WWW (graph nodes corresponding to WWW pages, edges to hypertext links). A query can specify complex conditions on node contents and their relationships. A W3QL query may use existing search services (e.g. Alta Vista). W3QL is extensible as users may use their own data analysis tools (e.g. image analysis). W3QS is a system that manages W3QS queries. W3QS is accessible via the WWW or by using a programming based interface (API). On the WWW, W3QS provides several interfaces: intuitive graphic interfaces, templates of frequently posed queries, and direct programming
