Abstract: At present, is a crucial method for obtaining effective domain knowledge from massive heterogeneous networks. For most current focused crawling technologies, there are some difficulties in obtaining high-quality crawling results. The main difficulties are the establishment of topic benchmark models, the assessment of topic relevance of hyperlinks, and the design of crawling strategies. In this paper, we use domain to build a topic benchmark model for a specific topic, and propose a novel multiple-filtering strategy based on local and global (MFSLG). A comprehensive method (CPEM) based on the web text and link structure is introduced to improve the computation precision of topic relevance for unvisited hyperlinks, and a (SA) method is used to avoid the falling into local optima of the search. By incorporating SA into the with MFSLG and CPEM for the first time, two novel strategies based on and SA (FCOSA), including FCOSA with only global (FCOSA_G) and FCOSA with both local and global (FCOSA_LG), are proposed to obtain topic-relevant webpages about s from the network. Experimental results show that the proposed crawlers outperform the other focused crawling strategies on different performance metric indices.

Modeling the influences of various rainstorms on the waterlogging in lake regions under the background of global warming

Zhu Yonghui,Lu Shaowei,Liao Hongzhi

Strategic Study of CAE 2010, Volume 12, Issue 6,   Pages 48-53

Abstract:

Based on the two-dimensional flow model and by applying the finite volume method and unstructured mesh, the waterlogging and drainage of the Datong Lake Region, heartland of the Dongting Lake Plain under various rainstorms were studied. The spatial distribution of waterlogging in the Datong Lake Region and the ratio of waterlogging were obtained. The negative influences of the increased intensity of the rainstorms on the waterlogging were analyzed quantitatively. The results of the research can provide technological support to the waterlogging forecasting and assessment.
