Web Information Extraction Based on List Pages of Nested Data
摘要
Abstract
On the basis of the existing algorithms of the nested data, the data mining algorithm was joined. According to the tag trees of constructed nested list pages, all data regions were found and unified handled. Then a global pattern was produced after all the subtrees were matched based on partial tree aligning algorithm. And all the data records were extracted. Compared with the original algorithm, the efficiency was improved by using the new method, and it ensured the accuracy.关键词
