Outline of Final Research Achievements |
This research developed a novel document retrieval technique based on co-citation networks that were improved by word-based linkages. Specifically, this research proposed two ideas: 'satellite documents' and 'rough co-citation' as keys to effectively enlarge co-citation networks. Results of the information retrieval experiments showed that the proposed retrieval methods, which used co-citation networks enlarged by these ideas, outperformed a baseline retrieval method using original co-citation networks.
