.... factors such as intentions and circumstances of the individuals involved in the communicative process [4, 34, 35] But, indexicals, demonstratives, tenses, and other linguistic devices rely heavily on context for their interpretation and are fundamental to the way language conveys information [2]. Contextdependence is an essential hypothesis of situation semantics; a given sentence can be used over and over again in different situations to say different things (the so called efficiency of language) Its interpretation, i.e. the class of situations described by the sentence, is therefore ....

....reader has presumably noticed that situations represent a way of modeling contexts. In fact, in [10] Barwise expounds why a context is a situation. Briefly, he proposes that there is a definite relationship between situations and what are known as context sequences in possible world semantics [2]. In possible world semantics, given a sentence s, the person p who uttered the sentence, the spatio temporal location of the utterance l and t, the object o that p is referring to, etc. are all lumped together into a sequence c = hp; l; t; o; i. Basically, c represents various contextual ....

....situation can carry different information. Context dependence, which was underestimated in classical approaches to semantics, is the essential hypothesis of situation semantics. Indexicals, demonstratives, tenses, and other linguistic devices rely heavily on context for their interpretation [1]. Therefore, a sentence can be used over and over again in different situations to say different things. Its interpretation is subordinate to the situation in which the sentence is uttered. The framework of situation theory mainly consists of the things an (intelligent) agent is able to ....
.... situatedness of information and constraints [31, 43] Each infon or constraint exists in a situation (more formally, is supported by a situation) Consequently, each infon or constraint has an interpretation according to the situation it exists in. This can be considered as context dependence [1]. To clarify the argument above, consider a constraint that deduces facts about the height of individuals. Let both Mike and John be 185 cm tall. Both are aware of the fact that if someone is higher than 185 cm, then that individual is taller than Mike and John. The following represents the ....

....to represent it clearly in the knowledge base. Dana Scott [14, p. 354] 1 Introduction Although the term context is frequently used in explanations, proofs, etc. in Artificial Intelligence, its meaning is left to the reader s understanding, i.e. it is used in an implicit and intuitive manner [1]. However, when we are to implement a system, we have to make this notion explicit using, hopefully, a formal approach. In this work, our aim is to offer a useful formalization of context, one that can be used for automated reasoning in Artificial Intelligence, Computational Linguistics, and so ....

McCarthy published his recent ideas on context in [27, 28] Other notable works on formalizing context 2 are due to Akman and Tin [1], Guha [21, 22] Shoham [32] Giunchiglia [18, 17, 7, 16] S. Buvac [8, 10, 11, 9, 28] and Reddy and Gupta [31] We are planning to use the context due to our recent research [36, 37] which allows us to have logical and encyclopedic information represented in a situation type with parametric and ....
