Results show that the improvement is very outstanding.展开更多

The concept model of a clauses ontology is composed of predicate parameters and head sub-goals, and these sub-goals appear in the head of the rule body and precede any predicate calls. In the proposed method, a Prolog program can be transformed into a Prolog + CG program that includes a clauses ontology. Some experiments show that, with a clauses ontology, some clauses which do not match current goals are not considered early enough, and, therefore, the size of the goal solution tree may be reduced. By the capability of conceptual graph, a clauses ontology makes the semantics of the Prolog program more clear and readable, and sometimes it speeds up the solution process obviously.展开更多

The data used in this study have been collected from English writing tasks and analyzed by Statistical Package for Social Sciences(SPSS17.0). The major findings of this study are stated as follows: 1) There are significant differences in the production of the relative clauses in their English writings by Chinese higher vocational college students and English native speakers. Avoidance of relative clauses exists in the English writings of higher vocational college students. 2) High-level Chinese higher vocational college students display less of the avoidance phenomenon in their English writings than low-level students.展开更多
