A computer-implemented information retrieval method comprising:
- extracting Web-based documents from a documents database with a data extractor;
- sending the extracted documents to a text management function;
- creating an indexed set of documents with an indexation function;
- storing and linking the indexed set of documents in an indexed documents database;
- receiving one or more user queries via a user interface at the text management function;
- enriching the queries via a query enrichment function;
- forwarding the enriched queries to one or more searching functions;
- browsing the indexed documents database according to one or more query terms with the searching function;
- forwarding the documents to the documents database;
- classifying the documents via a classifying function;
- and
- providing the documents to the user interface which is configured to display the results to a user.
An information retrieval system comprising:
- a data extractor configured for extracting documents from a documents database and sending the extracted documents to a text management function;
- an indexation engine configured for creating an indexed set of documents;
