ABSTRACT

ABSTRACT:

Most documents available over the web conform to the HTML specification. Such documents are hierarchically structured in nature. The existing graph-based or tree-based data models for the web only provide a very low level representation of such hierarchical structure.

The first part of this talk introduces a conceptual model for the web that is able to represent the complex hierarchical structure within the web documents at a high level that is close to human conceptualization/visualization of the documents.

The second part of this talk discusses how to automatically convert HTML documents into this conceptual model.

The last part presents a rule-based language based on this conceptual model to query the Web documents, which supports not only recursion and negation, but also query result restructuring.
