An Interinstitutional Center for Research and Development in Computational Linguistics

LINGUARUDO

An Approach for Natural Language Information Retrieval for Portuguese

Starting Time: 2001

Current Status

Ongoing project which is part of a PhD program (2001-2004)

Goals
1) To define one approach for Text Information Retrieval for Portuguese _ Linguarudo.

2) To apply Linguarudo to 2 prototypes, which are related with the search task: one meta-search engine, and one tool to help in the construction of new homepages showing what exist about one subject.

3) To evaluate the prototypes and contrast the results with others tools for Portuguese to see how good is Linguarudo.

Project's Features

This approach is going to use Natural Language Processing during all the process of retrieving information: indexing, matching, ranking.

Expected Results
1) An IR approach for Portuguese that gives to the users better quality results and that maybe can inspire some other works in tasks like information filtering, information answering and topic detection.

2) The 2 prototypes, Leva-e-traz and Maritaca, for initial tests that have chances to be:

The first meta-search engine for Portuguese with natural language interaction _ Leva-e-traz

The first tool to help the web analysts to decide the contents of a new web page _ Maritaca
