摘要： While the citation context of a reference may provide detailed and direct information about the nature of a citation, few studies have specifically addressed the role of this information in retrieving relevant documents from the literature primarily due to the lack of full text databases. In this paper, we design a retrieval system based on full texts in the PubMed Central database. We constructed two modules in the retrieval system. One is a reference retrieval module based on citation contexts. Another is a citation context retrieval module for searching the citation contexts of a specific paper. The results showed that the retrieval system performed very well on searching highly cited papers and classic papers. The citation contexts of a paper might be related to many topics. Finally, tag cloud is employed to present these topics.
