摘要
提出了通过结构模式提取,在信息源对缺失信息进行恢复与重构的思想,给出了结构模式提取模型,并讨论了实现该模型的关键步骤与算法,最后结合基于该模型实现的系统对半结构化文档集的结构模式提取及其应用进行了总结。该研究成果已成功应用于实际系统中。
A model of structure extraction was brought forward in the paper. First, an idea was given that the semantic structure information been extracted at information source through the rules of the relation between semantic structure information and style information. Then, the paper puts forward a model how to extract structure of semi-structured document. The key step and key algorithm were discussed in detail. Last, the extraction method and its application were summarized with an system, which had been constructed based on the scheme. The idea and the method had been used in an applied system with success.
