RT Journal Article T1 Towards a Notion of Basis for Knowledge-Based Systems—Applications A1 Aranda Corral, Gonzalo Antonio A1 Borrego Díaz, Joaquín A1 Galán Páez, Juan A1 Rodríguez Chavarría, Daniel AB In the paradigm of Knowledge-Based Systems (KBS), the design of methods to simplify thereasoning leads to more efficient processes. A point of view that provides valuable insights is thealgebraic one. In this work, a notion of basis (and dimension) for Knowledge Bases in PropositionalLogic associated with knowledge forgetting is introduced. It is based on ideas that come fromthe translation of such logic in (Computer) Algebra, particularly from the interpretation of variableforgetting. In this paper, the concept of weak base is defined as a set of variables sufficient to decide theconsistency using variable forgetting. Several applications of weak bases are presented in order toshow their usefulness in KBS reasoning and to justify their study and use in solving problems withinthis topic.
