| Abstract(in English) | In a text retrieval system, there are three types of retrieval methods: word retrieval, textual relationship retrieval, and ontology retrieval. However, none of these methods can search for the conceptual meaning of a text itself when it appears in the context, in other words, a search similar to the act of reading between the lines (we call this latent text search). In this paper, latent texts are considered as random variables. Latent random variables are probabilistic categories for latent texts, to which the topic model is applied. On the other hand, ontology and probability space are defined to have a corollary relationship with each other, and latent texts are represented by interpreting random variables from the ontology side. In this paper, we propose a model that relates entropic co-occurrences on the probability space side as an ontology. Furthermore, we show the validity of defining co-occurrence as the change in entropy between topics caused by changes in the number of topics in the topic model. |
