Understanding information contained in texts and symbols requires extensive background knowledge. This knowledge is stored in semantic memory. Recently manually created ontologies and dictionaries became very popular but still do not contain sufficient information for many applications, such as semantic search or automatic annotation of concepts. Architecture facilitating knowledge acquisition for common sense semantic memories is presented and an algorithm for playing 20 questions word game used for further verification and acquisition of new knowledge. This approach is then applied to the WordNet database for gathering new and correcting existing knowledge.

Keywords: knowledge acquisition, commonsense knowledge, ontologies, semantic memory, Wordnet, text understanding, semantic Internet, NLP.
