The ability to organize these health QA records has been found to be effective for data access. The existing approaches for organizing information are often not applicable to health domain due to its domain nature as characterized by complex relation among entities, large vocabulary gap, and heterogeneity of users. To tackle these challenges, we propose a top-down organization scheme, which can automatically assign the unstructured health-related records into a hierarchy with prior domain knowledge. Besides automatic hierarchy prototype generation, it also enables each data instance to be associated with multiple leaf nodes and profiles each node with terminologies. Based on this scheme, we design a hierarchy-based health information retrieval system. Experiments on a real-world dataset demonstrate the effectiveness of our scheme in organizing health QA into a topic hierarchy and retrieving health QA records from the topic hierarchy. date: 2016-11-17 date_type: published official_url: https://doi.org/10.1186/s13637-016-0053-x oa_status: green full_text_type: pub pmcid: PMC5114333 language: eng primo: open primo_central: open_green article_type_text: Journal Article verified: verified_manual elements_id: 1561717 doi: 10.1186/s13637-016-0053-x pii: 53 lyricists_name: Akbari, Mohammad lyricists_id: MAKBA16 actors_name: Cuccu, Clara actors_id: CCCUC40 actors_role: owner full_text_status: public publication: EURASIP Journal on Bioinformatics and Systems Biology volume: 2016 article_number: 18 event_location: Germany issn: 1687-4145 citation: Akbari, M; Hu, X; Nie, L; Chua, T-S; (2016) Towards organizing health knowledge on community-based health services.
