It tries to take advantage of the great amount of information existent in the World Wide Web. Since Portuguese is one of the most used languages in the web and the web itself is a constantly growing source of updated information this kind of techniques are quite interesting and promising. 1 Introduction There are some question answering systems for Portuguese like the ones developed by the University of Évora Quaresma and Rodrigues 2005 and Priberam Amaral et al 2005 but these systems rely heavily on the pre-processing of document collections. Esfinge explores a different approach instead of investing in preprocessing corpora it tries to use the redundancy existent in the web to find its answers. In addition it has an interface on the web where everyone can pose questions to the system http Esfinge . Esfinge is based on the architecture proposed in Brill 2003 . Brill suggests that it is possible to obtain interesting results applying simple techniques to large quantities of data. The Portuguese web can be an interesting resource for such architecture. Nuno Cardoso . is compiling a collection of pages from the Portuguese web and this collection will amount to pages. Using the techniques described in Aires and Santos 2002 one can estimate that Google and Altavista index 34 900 000 and 60 500 000 pages in Portuguese respectively. The system is described in detail in Costa 2005a 2005b . 2 System Architecture The inputs to the system are questions in natural language. Esfinge begins by transforming these questions into patterns of plausible answers. As an example take the question Onde fica Braga Where is Braga located . This generates the pattern Braga fica Braga is located with a score of 20 that can be .
