Automatic key phrase extraction is funda- mental to the success of many recent digital library applications and semantic information retrieval techniques and a difficult and essen- tial problem in Vietnamese natural language processing (NLP). In this work, we propose a novel method for key phrase extracting of Vietnamese text that exploits the Vietnamese Wikipedia as an ontology and exploits spe- cific characteristics of the Vietnamese lan- guage for the key phrase selection stage. We also explore NLP techniques that we propose for the analysis of Vietnamese texts, focusing on the advanced candidate phrases recogni- tion phase as well as part-of-speech (POS) tagging.
