Java: Generate RDF from Web Pages

WebCAT is an extensible tool to extract meta-data and generate RDF descriptions from existing Web documents. Implemented in Java, it provides a set of APIs (Application Programming Interfaces) that allow one to analyse text documents from the Web without having to write complicated parsers.

Among other things, WebCAT provides:
  – Language and encoding detection.
  – Hyperlink extraction.
  – Text tokenization (words, n-grams, sentences).
  – Document fingerprinting.
  – Format conversion.
  – Metadata extraction and normalization.
  – Named Entity Extraction.
  – Document classification.

The considered meta-data elements are particularly suited to the domain of automated search, making this a good tool to use in other information retrieval and extraction projects.
