A lot of information written in natural language is stored, generating the need for users to automatically manage the knowledge that is contained in these texts, for query, retrieval, updating, or elaborating of new knowledge (Bolshakov and Gelbukh, 2004). It should be noted that, despite having computing machines to carry out such management, there are still great difficulties in the task of representing the knowledge contained in texts written in natural language and its implementation on computers.
The problem presented above, gives rise to the following research question: How to build units that contain the knowledge which is immersed in the texts written in natural language, which can be implemented properly in a computer? This article aims to present the first part of the answer, related to the construction of knowledge units. At this point it is important to clarify the concept "knowledge unit", which has been mentioned above.
