A concept–relationship acquisition and inference approach for hierarchical taxonomy construction from tags

Eric Tsui, W.M. Wang, C.F. Cheung, Adela S.M. Lau
2010 Information Processing & Management  
Taxonomy construction is a resource-demanding, top down, and time consuming effort. It does not always cater for the prevailing context of the captured information.  ...  Common taxonomy construction techniques are based on 3 main approaches: clustering, lexico-syntactic pattern matching, and automatic acquisition from machine-readable dictionaries.  ...  The authors also like to thank Dr CC Kiu for her valuable contributions towards the experimentations and feedback on several versions of this paper.  ...
