英文摘要：

Citation context of a reference may provide detailed and direct information about the nature of a citation, including cited reasons, cited aspects and cited values. These citation contexts could provide important information for citation retrieval and citation recommendation. In this paper, we design a citation retrieval and recommendation system based on full texts in the PubMed Central database. This system is completely dependent on the citation context. The results showed that the system perform very well on citation retrieval and recommendation, especially on the recommendation of highly cited literatures and classical literatures of a field, showed very precise retrieval performance .
