The framework extends the semantic web model and controls the dynamic security of semantic web services, such as trust, logic and reasoning. It includes four layers, that is, a trust entrance layer, a social intelligence layer, a transaction layer, and a TCP/IP security protocols layer. The trust entrance layer deals with trustable features from users. Social intelligence layer is responsible for logical questions for a semantic web. The transaction layer carries out transaction reasoning. And the TCP/IP security protocols layer ensures security communication. These layers can cooperate to build closed-security-ring with different security grades. The integrated security framework provides an integrated security method for semantic web flow so that it is universal for various semantic web technologies.展开更多

On the basis of Danesi＇s Conceptual Fluency theory and actual learners＇ oral abilities, this research conducted two types of tests： a discourse-completion test and a dialogue-interpretation test. The research has found that L2 learners are often influenced by L1 conceptual system, and speeches are not necessarily appropriate and native-like.展开更多

This is especially true for the Senegalese public who more and more loses confidence in the political class. The public tends to look at the identity of the political personality and its personal values （morality credibility） to determine what to make of his/her words. On their side, politicians also begin promoting their image through their speeches. At this level, religious ethics seems to be unanimously considered a criterion of good morality among Senegalese politicians. We will try to look through Perelman＇s theory of argumentation, which Amossy redefined, how, in order to reach the audience, politicians adapt their words to the public, and enhance principles cherished by the populations to win the battle of the image and confidence.展开更多

Proverbs can actually be viewed as succinct sayings that convey semantically-laden units expressing a people＇s worldview. In this paper, an attempt is made to illustrate the effectiveness of using culture-specific units like French proverbs to teach challenging grammatical features to English-speaking students in a French class. For example, grammatical aspects like verb conjugation French syntax, etc., can be effectively tackled. Translational techniques could then serve as pedagogical tools to bring about a better grasp of the foreign language being acquired, and in the process, exposure to a larger world culture would be achieved展开更多

This paper concentrateson channel decoders that exploit the residual redundancy inherent in the enhanced variable ratecodec bitstream. This residual redundancy is quantified by modeling the parameters as first orderMarkov chains and computing the entropy rate based on the relative frequencies of transitions.Moreover, this residual redundancy can be exploited by an appropriately 'tuned' channel decoder toprovide substantial coding gain when compared with the decoders that do not exploit it.
