Efficiency improvement of literature survey based on citation-reason visualization

Literature survey is the first step of scientific research. However, this process could be quite time-consuming. Previous works aiming to automatically address this issue employ textual similarity or reference-relation between papers, while neither of which is flexible enough for context-specific demanded In this paper, we have proposed an idea to narrow down the search range for relevant literatures based on citation-reason visualization. Practicality and efficiency improvement of literature survey has been confirmed according to the results of the evaluation experiments.
