Abstract
While studies investigating the semantic similarity among concepts, sentences and short text fragments have been fruitful, the problem of document-level semantic matching remains largely unexplored due to its complexity. In this paper, we explore the document-level semantic similarity issue in the academic literatures using an interpretable method. To integrally describe the semantics of an article, we construct a topic event model that utilizes multiple information facets, such as the study purposes, methodologies and domains. Furthermore, to better understand the documents and achieve a more accurate similarity comparison, we incorporate external knowledge into the topic event construction and similarity calculation. Our approach achieves significant improvements over state-of-the-art methods.
