Multi-view text data consist of texts from different sources. For instance, multilingual Wikipedia corpora contain articles in different languages which are created by different group of users. Because multi-view text data are often created in distributed fashion, information from different sources may not be consistent. Such inconsistency introduce noise to analysis of such kind of data. In this paper, we propose a probabilistic topic model for multi-view data, which is robust against noise. The proposed model can also be used for detecting anomalies. In our experiments on Wikipedia data sets, the proposed model is more robust than existing multi-view topic models in terms of held-out perplexity.
