摘要	Pragmatics plays an important role in correctly understanding sentences. Much useful information will be lost if the context in which a sentence is asserted is ignored. There are some approaches in logic to pragmatics, such as situation theories and context logics. Although these methods associate a sentence with a context or a situation, they consider only the truth value of the sentence. However, a sentence should have more meanings than its truth value, and people care more about what a sentence conveys. For the affection of contexts, the meaning of a sentence is not always its semantic meaning and a sentence may have different pragmatical implications in different contexts. In this paper, a context is considered as some structure in the real world. A sentence from some logical language is conceptualized as a concept, whose intent is a set of sentences implied semantically by the sentence, and whose extent is a set of contexts in which the sentence describes a part of the contexts. In terms of tools and theories of concepts, a strictly defined theory is given to study the pragmatics of sentences in contexts in information systems, which cannot be derived from the sentences by using logical reasoning methods.
