This paper by Trevor Savage, Bogdan Dit, Malcom Gethers, and Denys Poshyvanyk discusses Latent Dirichlet Allocation (LDA) for exploring topics in source code. LDA is a probabilistic topic model that represents documents as mixtures of topics. The paper introduces the concept of Maximal Weighted Entropy (MWE) to capture the average probability and distribution of topics, enabling a deeper understanding of source code structures. This presentation was given at the 26th IEEE International Conference on Software Maintenance in Timișoara, Romania on September 16, 2010.

TopicXP: Exploring Topics in Source Code using Latent Dirichlet Allocation Trevor Savage, Bogdan Dit,Malcom Gethers and Denys Poshyvanyk 26th IEEE International Conference on Software Maintenance Timişoara, Romania September 16, 2010
Latent Dirichlet Allocation (LDA) • Probabilistic Topic Models (Latent Dirichlet Allocation –LDA [Blei’03]) • Models documents as mixture of topics
Maximal Weighted Entropy (MWE) • Occupancy(tj) captures the average probability of topic tj • Distribution (tj) captures distribution of tj using information entropy • MWE(Cj)=max(Occupancy(tj) x Distribution (tj))
