Abstract

In this work, we introduce a framework as a modeling and implementation tool to compute with words. The basis of the framework is a computational model called object networks. We present the mathematical concept of objects, generic objects and fuzzy objects. The interaction of these elements composes object systems. In particular, emphasis is given on a special class of object systems, the object networks. They are proposed here as a dynamic software architecture suitable for handling the issues involved when computing with words, but independent of the specific numerical algorithms used. The object networks architecture is easily translated into computer programs, and support explanatory databases build upon atomic pieces of information and from the query entered, among other important features. It is also shown how object networks manage semantics of linguistic, semiotic terms, to provide higher level linguistic computations. Illustrative examples are also included.
