摘要：
This paper describes the general architecture of a Portuguese relational lexical-conceptual database and a Question-Answering (QA) system - INQUER - that allows users to interact with this database by means of a natural language interface. This system provides direct natural language answers to user's questions by applying inference and information extraction mechanisms. Although these tools are being developed for Portuguese, both the theoretical approaches and the technologies used are language independent.
