Abstract:
Objective Based on scientific research grants to explore the feasibility of analyzing the subiect's hot topics. Methotis The CRISP(Computer Retrieval of Information on Scientific Projects)database of National Institutes of Health was used to retrieve the grants related of gene mechanism of essential hypertension in 2006. We obtained concepts from the fields of title and abstract by MetaMap. and then analyzed the key concepts about genes that were found more than 3 times. Results There were 73 related grants about that from CRISP in 2006. After processing the samples by MetaMap, we got 45 high frequency concepts about genes. which were divided into seven groups. Conclusions It iS feasible to analyze and study subject hotspot by scientific research grants. and it can be used to the supplement of normal literature analysis. MetaMap is a better tool for natural language processing, but also has some limitations.
