    On the basis of concept lattice theory, this article proposes a new method named Granularity Concept Analysis (GCA) based on formal concept analysis for the keywords analysis, and different granularity concept lattices are built with GCA focusing on the keywords of Ontology literatures in the open access resources. By mining of different granularity concept lattices, the analysis on high-frequency keywords and relative low-frequency keywords are executed in Ontology field, and the structure of knowledge and inherent association are discovered in Ontology field, in order to explore a new approach for literature keywords analysis.

    The paper mainly reviews the semantic relation extraction studies used key verbs(i.e.semantic verb),and introduces the methods of biomedical semantic relations extraction. The key verbs used in the present researches are manually selected, so the verb selection method involves more subjective factors, and influences the objectivity, accuracy and comprehensiveness of key verbs selection.Therefore, how to find these verbs automatically may be a key task of relations mining.

The algorithm provides a better way to construct term context patterns. Meanwhile, term context characters are kept well in patterns. The paper also presents the specific implementation steps of new algorithm, and evaluates the algorithm on basis of gene engineering field experiment data set. Experiment result demonstrates that the algorithm has an obvious improvement in computing performance.

    Based on the text clustering requirement from the embedded NSTL Recommending System, this paper researches on the BWP algorithm, and analyzes the shortage of the BWP. Then an improved algorithm is proposed to optimize the calculation of the distance within the single sample cluster. The improved algorithm enlarges the range of clusters number based on the BWP. Moreover, it changes the partial optimum into the whole optimum. At last, the test result shows it is effective and efficient.

    This paper introduces a method for trademark retrieval system using combination features. In this method, a color histogram is first generated for color description, 2D Fourier transform and Zernike moment are then combined to apply to shape features extraction. This method is evaluated on MPEG-7 CE2B and 1 000 trademark images database and is compared with the existing methods. The experimental results show that the performance of this method is acceptable.

    This paper analyzes data standardization of multiple attribute evaluation in science and technology evaluation. The results show the evaluation score of side standardization is smaller than tunable standardization. Tunable standardization may increase evaluation score of lower level journals, linear standardization may affect evaluation score but cant affect evaluation ranking, and negative indicator standardization may change the evaluation ranking. The authors give a new linear negative indicator standardization method, and point out that the negative classical indicator standardization should be abandoned, and the evaluation institute should make known to the public of data standardization method so as to keep evaluation justice.
