Abstract:Conventional analysis of subject research attention and research method is based on the scientific literature to identify the Keywords. In order to improve the conventional research evaluation method, this paper associated scientific data and? literature, forming the scientific content of the whole, making the literature and data jointly serve the subject attention evaluation. In botany, for example, this paper established a set of subject attention assessment method, in order to provide evaluation information for scientific research management policy and scientific research layout planning. After expert consultation and mathematical method verification, this method can be constructed reasonably, and the evaluation results are in line with the general understanding of researchers, and can be extended to the attention assessment of other disciplines. At the same time, two suggestions are given: 1. Strengthen the role of scientific data attention in scientific research evaluation.2. Strengthen the integration of scientific data and literature in scientific research layout.
