Concept map is a graphical tool that is widely used for organizing and representing knowledge and shows the relationships among related concepts. Automatic concept map construction from text documents requires methods for extracting concepts and relationships (taxonomic and non-taxonomic). Even though a lot of studies have been conducted to automatically construct a concept map, they still have some limitations such as a resolution of anaphora problem and defining relationships to form propositions. In this paper, we propose a clustering-based approach for constructing a concept map from text documents. First, relevant concepts are extracted using typed dependency linguistic patterns. Anaphoric resolution for pronouns is then introduced to map the pronouns with candidate terms. Second, extracted concepts are clustered using affinity propagation algorithm. Finally, relationships are assigned between the extracted concepts in each cluster. Our empirical results show that the constructed concept maps conform to the outputs generated manually by domain experts. Furthermore, domain experts verified that the constructed concept maps are in accordance with their knowledge.
