摘要
为了提高Web Services合成的效率,减少用户查询时过多的人工干预,提出了一个Web Services最佳路径动态合成框架。在该框架下以产生式的形式建模,构建一个适合于最佳路径算法的DAG图,以参数级本体解决合成过程中的语义冲突问题,并通过最佳路径算法进行合成。通过分析比较,该框架特别适合于对同样的用户输入和Web Services进行多次合成以生成相同的或者不同的输出,同时也避免了回溯和对合成方案的优化。
In order to increase the composition efficiency of web services and decrease the overabundance man work on user query, a framework of best path web services dynamic composition is proposed. Under the framework, using a production rule method to model to form a DAG that suitable for the best path algorithm and using a parameter-level ontology to eliminate the sematic conflict of the composition, then using the algorithm to compose web services. By analysing and comparing, the framework proposed is particularly suitable for many times to the same user inputs and the same web services in order to generate the same outputs or different outputs, and avoid the non-backtrace and the optimization of the composition plan.
