Service components are published externally as normal web services and can thus be employed by webbased applications. In order to improve reusability and testability of service components, the concept of composition pattern is also proposed, which presents the relationships among service components. The relationships and relationship compositions have a rigorous semantic, so that composite components can be validated at the configuration stage. The composition patterns support to integrate service components of various levels of granularity. Experience indicates that the application assembly can effectively be conducted by understanding, selecting, and reusing components easily.展开更多

We find that the sentences written by foreign learners of Chinese (hereafter simplified as FLC) with the wordfanzheng are quite similar to those by Chinese native speakers in the distribution of the syntactic categories, semantic types, semantic functions, pragmatic or discourse functions. These characterize basically the wordfanzheng as one of the modal adverbs in such three aspects as syntax, semantics and pragmatics. Most of the FLCs study the basic meanings and typical contexts of the wordfanzheng at primary stage, and later the functions emphasizing reasons, summary or explaining, and then the function of textual cohesion at the intermediate and advanced stage. The main causes of errors reflect that the FLCs are not able to differentiate the usage offanzheng and that of other causal or adversative conjunctions.展开更多
