Topic Modeling of Hierarchical Corpora /

We study the problem of topic modeling in corpora whose documents are organized in a multi-level hierarchy. We explore a parametric approach to this problem, assuming that the number of topics is known or can be estimated by cross-validation. The models we consider can be viewed as special (finite-dimensional) instances of hierarchical Dirichlet processes (HDPs). For these models we show that t...

Modeling corpora of timestamped documents using semisupervised nonparametric topic models

In this paper we propose a nonparametric topic model to capture the evolution of text over time. Mixture models for modeling text documents based on hierarchical Dirichlet processes (HDP) have been used successfully in recent work to provide a nonparametric prior for the number of topics in the corpus eliminating the need to specify apriori the number of topics. We extend this model to addition...

Fuzzy Approach Topic Discovery in Health and Medical Corpora

The majority of medical documents and electronic health records (EHRs) are in text format that poses a challenge for data processing and finding relevant documents. Looking for ways to automatically retrieve the enormous amount of health and medical knowledge has always been an intriguing topic. Powerful methods have been developed in recent years to make the text processing automatic. One of t...

Co-word maps and topic modeling: A comparison using small and medium-sized corpora (N < 1, 000)

Induced by “big data,” “topic modeling” has become an attractive alternative to mapping cowords in terms of co-occurrences and co-absences using network techniques. Does topic modeling provide an alternative for co-word mapping in research practices using moderately sized document collections? We return to the word/document matrix using first a single text with a strong argument (“The Leiden Ma...
