Abstract

To improve the performance of the expert finding system, a topic-centric candidate priors (TCCP) model was proposed. This model treated the documents as mixtures of topics. The topics of the candidates and terms were then used as latent variables to calculate the candidate priors. Latent Dirichlet Allocation (LDA) was utilized to find the topics. Finally, the parameters of the model were estimated using Gibbs sampling. The performance of the proposed model was evaluated using the CSIRO Enterprise Research Collection. The results showed that the performance of the expert finding system was dramatically improved by using the candidate priors estimated by the TCCP model. Compared to classical models, the proposed candidate priors model exploited the information in the whole data corpus and thus furnished more reasonable candidate priors.
