Abstract

The collaborative filtering techniques is applied to cost estimation of software projects in the paper, and four methods to calculate similarity in collaborative filtering are introduced which are cosine similarity, Euclidean distance, adjusted cosine similarity and correlation correction similarity. These methods are applied in USP05-FT projects to estimate cost, and the experimental results show that the adjusted cosine similarity and correlation correction similarity are better than other similarity calculation methods whose accuracy has reached more than 75%.
