Welcome to the LX-Center




LX-Center hosts the linguistic resources, services and tools developed in all or part by the NLX-Natural Language and Speech Group at the University of Lisbon, Department of Informatics.

These services are freely available online on a best-effort basis to help foster the education, research and development in the realm of natural language science and technology.

They are meant also to showcase some of our research results in cognitive science and natural language processing.


You may also be interested in the demo of an application based on these tools, the XisQuê, a web-based domain-independent question answering service for the web of documents written in the Portuguese language.
