The standard semantic web languages and reasoning tools do not explicitly take into account the contextual dimension of knowledge, i.e., the fact that a certain statement (RDF triple) is not universally true, but true only in certain circumstances. Such contextual information, which includes for instance, the time interval, the spatial region, or the sub-domain in which a certain statement hold...

logical form or covert syntax is a syntactic level introduced in recent generative approaches. using the ideas of first-order predicate logic, it interprets the strings whose elements cannot move in s–structure, because an element moves if it does not acquire its necessary scope. but unlike the predicate logic, logical form is based on syntactic principles and rules. therefore, logical form is ...

Semantic Networks (SN) have been used in many applications, especially in the field of natural language understanding (NLU). The multflayered extended semantic network MESNET presented in this paper on the one hand follows the tradition of semantic networks (SN) starting with the work of Quillian (13). On the other hand, MESNET for the first time consequently and explicitly makes use of a multi...

The paper presents a computationally tractable application of Bulgarian pronouns representation using Universal Networking Language (UNL) formalism. It analyses grammar features of pronouns and offers a model of their formal representation based on incorporation of grammar, semantic and lexical knowledge by using standard UNL knowledge representation mechanisms. The entire application presents ...
