Retrieval method for traceability links between source code and Chinese documentation

In this paper,a retrieval method for traceability links between source code and Chinese documentation is proposed,according to several features of Chinese software documents and source code.Based on the latent semantic indexing model,three strategies are used to improve: hierarchical enhancement,identifiers classifying,and data dictionary.Experimental results show that all the three strategies could increase the recall by 4% to 28% under the same extracted threshold and the precision by 8% to 30% under the same recall.
