RT Conference Proceedings T1 Inference of mixed information in Formal Concept Analysis A1 Mora-Bonilla, Ángel A1 Cordero-Ortega, Pablo A1 Enciso-García-Oliveros, Manuel A1 Rodríguez, Jose Manuel K1 Lenguajes formales K1 Lógica simbólica y matemática AB Negative information can be considered twofold: by means of a negation operator or by capturing the absence of information. In this second approach, a new framework have to be developed: from the syntax to the semantics, including the management of such generalized knowledge representation. In this work we traverse all these issues in the framework of formal concept analysis, introducing a new set of inference rules to manage mixed (positive and negative) attributes.
