Semantic-relations taxonomy for knowledge representation

Time Representation: A Taxonomy of Internal Relations

James Allen in [AZZ2] formulated a calculus of convex time intervals, which is being applied to commonsense reasoning by Allen, Pat Hayes, Henry Kautz and others [AZZKuu, AZZHay]. For many purposes in AI, we need more general time intervals. We present a taxonomy of important binary relations between intervals which are unions of convex intervals, and we provide examples of these relations appl...

Developing a Taxonomy of Semantic Relations in the Oil Spill Domain for Knowledge Discovery

The paper presents the rationale, significance, method and procedure of building a taxonomy of semantic relations in the oil spill domain for supporting knowledge discovery through inference. Difficult problems during the development of the taxonomy are discussed and partial solutions are proposed. A preliminary functional evaluation of the taxonomy for supporting knowledge discovery was perfor...

Semantic Knowledge Representation Project

Activity- and taxonomy-based knowledge representation framework

Elaborations of Competence-based Knowledge Space Theory (CbKST) incorporate skills that refer to the conceptual information of the domain as well as to the activities learners are expected to perform in this context. Thus, they are suggested as a formal knowledge representation framework that is able to take into account current activity-oriented pedagogical trends in designing effective Units ...

Knowledge Representation for Syntactic/Semantic Processing

1. Introduction This paper discusses some theoretical implications of recasting parsing and semantic interpretation as a type of inference process which we call incrementalhescription refinement.* It draws upon our recent experience with RUS. a framework for natural language processing developed at BBN and in use in several different natural language systems across the country (for details see ...
