A group of transition probability functions form a Shannon’s channel whereas a group of truth functions form a semantic channel. By the third kind of Bayes’ theorem, we can directly convert a Shannon’s channel into an optimized semantic channel. When a sample is not big enough, we can use a truth function with parameters to produce the likelihood function, then train the truth function by the c...

the coalition between terms and their meaning can be as the result of phonological repetition in its speech structure and specific semantic load. this can lead to meaning distinction in choosing words and also meaning association. therefore, literally and syntactically, the phonological level cannot be separated from semantic level. earlier, the phonological association in text has been discuss...

in the present paper, we are to put forth a paradigm for the systematic study of modality in persian.with this end in view, we consider modality as a linguistic phenomenon that can be expressed at the level of sentence, at the level of constituents smaller than sentence and/or at the level of discourse. in such a system where sentential modality, sub-sentential modality and discourse modality a...

the link between studies in discourse analysis and corpus linguistics has created new fields of research previously unattended. one of these areas is the study of semantic prosody produced through frequent collocation of a lexical item with a collection of words. semantic prosody is the positive, negative or neutral shade of meaning which a seemingly neutral word adopts after frequent collocati...

In translation, choosing appropriate equivalent is essential to convey the right message from source-text to target-text, and one of the issues that may have a determinative role in appropriate equivalent choice is the semantic prosody (SP) behavior of words and the relation existing between the SP of a word and semantic senses (i.e. negativity, positivity or neutrality) of its collocations in ...

web search engines are one of the most popular tools on the internet which are widely-used by expert and novice users. constructing an adequate query which represents the best specification of users’ information need to the search engine is an important concern of web users. query expansion is a way to reduce this concern and increase user satisfaction. in this paper, a new method of query expa...
