A system that extracts knowledge from texts is presented. It is also indicated how the inferences necessary for the extraction of knowledge can be acquired by the system from sentences entered by users. The knowledge acquisition component is grounded on a semantic interpreter of English based on an enhanced WordNet. An evaluation of the system performance is included.
