Building knowledge-based systems today usually entails constructing a new knowledge base from scratch. Even if several groups of researchers are working in the same general area, such as medicine or electronic diagnosis, each team must develop its own knowledge base from scratch. The cost of this duplication of effort has been high and will become prohibitive as we build larger and larger syste...
EcoLexicon is a multilingual terminological knowledge base (TKB) on the environment that targets different user groups who wish to expand their knowledge of the environment for the purpose of text comprehension and/or generation. Users can freely access EcoLexicon, and are able to find the information needed, thanks to a user-friendly visual interface with different modules for conceptual, ling...
Abstrract:For many application domains the best way to produce intelligent behavior is to encode knowledge about this domain to knowledge base. Verification of KB is one of the crucial issues in developing reliable knowledgebased systems. SAT techniques as resolution and DPLL can be used for verifying knowledge bases. We give a transformation of a DPLL refutation to a resolution refutation of a...
chapter one is devoted to a moderate discussion on preliminaries, according to our requirements. chapter two which is based on our work in (24) is devoted introducting weighted semigroups (s, w), and studying some famous function spaces on them, especially the relations between go (s, w) and other function speces are invesigated. in fact this chapter is a complement to (32). one of the main fea...
abstract the present study was conducted to examine the effect of proficiency on students interaction while carrying out the grammar-based task(s) in collaboration. in particular, the study examines whether the level of proficiency affects the learners’ focus of attention to grammatical and lexical features. the study takes a further step and examines whether there is any difference in the use...
Knowledge base systems have not captured the wide audience enjoyed by database management systems (DBMS). The capabilities of the most high-end knowledge representation and delivery systems are extensive, but may not be pragmatic or accessible to a large community of potential users. We present SOPHIA, a frame-based knowledge architecture which is built upon a relational DBMS (RDBMS) to provide...
Diierent requirements for the representation of the factual knowledge for the use in mechanised reasoning systems are represented. In particular, we distinguish diier-ent types of knowledge: axioms, deenitions (for introducing concepts like \set" or \group") and theorems (for relating the concepts) for formulating concepts and their relationships, as well as proofs, examples and counterexamples...
This thesis explores hierarchy as a knowledge representation strategy. I will examine the use of hierarchy to represent knowledge about place, a natural candidate given the importance of the inclusion relationship between places. I shall show that for a. first order theory of place, hierarchy proves economical and powerful, effectively expressing regularities of place implicit in statements suc...
