Constructing Dirichlet Forest Priors for Logically Constrained Topic Models

Abstract (in Japanese) (See Japanese page) 
(in English) This paper describes a simple method to incorporate logical expressions of term-constraints into Dirichlet forest priors on a recently developed, term-constrained topic modeling framework (LDA-DF). Our method allows us to add new constraints without changing the algorithm, as well as covering the original constraints of LDA-DF. We discuss the validity of the algorithm by defining its asymptotic behaviors. We verify the effectiveness of our method with comparative studies on synthetic corpora and interactive topic analysis on a real corpus.
