一种半自动化提取COSMIC功能用户的方法

A Semi-Automated Method of Extracting COSMIC Functional Users

摘要: COSMIC方法是当今功能点规模度量方法的主流之一，但是在实践中常因为缺少易于操作的方法指导，或者对需求文档中自然语言的理解不同造成一定的偏差。本文将COSMIC官方手册中的部分原则和规则，细化为具体的十个处理步骤，提出了一种基于智能工具的半自动化需求预处理方法，一定程度上解决了度量手册中没有给出具体的实施流程，以及度量人员主观臆断引起的度量不一致等问题。实践证明，该方法能够完成COSMIC方法度量策略阶段的所有工作并能够提取出候选功能用户，同时为下一步COSMIC度量的自动化提供了一定的参考。

Abstract: COSMIC is one of the mainstream function point size measurements, but in practice will lead a certain deviation because of the lack of guidance which is easy to operate or the different com-prehensions of the natural language in requirement documents. We subdivide parts of principles and rules in COSMIC official manual into ten specific processing steps. We present a semi-auto- mated need pretreatment method based on smart tools. To some extent, we solve the problems of not giving a specific implementation process and measurement inconsistency caused by the personnel subjective measure in the measurement manual. Practice shows that by using the method we can complete all the work in the stage of strategies, be able to extract the candidate functional users and provide some reference for automated measurement of COSMIC in the future.
