摘　　要：设计模式是对于特定软件设计问题的经过验证的解决方案,通常用来获取为解决软件设计问题所需的软件知识,但选出合适的设计模式却并非一件容易的事。设计模式意图是理解设计模式的最短路径,因此通过解析设计模式意图对设计模式排序,更利于用户获得所需设计模式。文中提出了一种基于意图的设计模式排序方法,以方便设计模式的选择,定义了相关相似度的计算方法并在文中给出相应的证明,而后通过遗传算法对所定义的参数进行了调整和优化,最后用软件实际开发中实际问题数据集和设计模式集合,在提出的方法上进行了验证和分析。实验结果表明,该方法相比其他方法在匹配率上有一定提高,且排序后使得更多正确的结果出现在靠前的位置。Design patterns are proven solutions to specific software design problems and often used to acquire the software knowledge needed to solve software design problems,but choosing the appropriate design patterns is not an easy task.Design pattern intent is the shortest path to understand design patterns,so sorting design patterns by analyzing design pattern intent is more beneficial for users to obtain the required design patterns.We propose an intent-based ranking method to facilitate the choice of design patterns,define the relevant similarity calculation method and give the corresponding proof.Then,the parameters defined are adjusted and optimized by genetic algorithm.Finally,the proposed method is verified and analyzed by using the data set of practical problems and design patterns in the actual software development.The experiment shows that compared with other methods,the matching rate of the proposed method is improved to a certain extent,and more correct results appear in the first place after sorting.
