A metric space based software clone detection approach

摘要

Metric space is a set with definition of distance between eiements within this set. This paper introduces metric space into code cione detection, and uses the distance within a metric space to measure the simiiarity ievei of code. It proposed a process of building up a metric space to detect clones in software system. Based on metric space which is derived from software metric, the clone detection can get more convenience and flexibility. We also exercise the approach in a real industry project.
