2004 Lecture Notes in Computer Science  
Furthermore, based on different block level, inter-hyperlink and intra-hyperlink can be two relative concepts. Thus which level should be optimal to distinguish the intra-or inter-hyperlink?  ...  In recent years, information retrieval methods focusing on the link analysis have been developed; The PageRank and HITS are two typical ones According to the hierarchical organization of Web pages, we  ...  Modified PageRank After obtaining the block-based Web structure, we apply a link analysis algorithm similar to PageRank to re-rank the web-pages. We construct a matrix to describe the graph.  ...

Web2Text: Deep Structured Boilerplate Removal [article]

Thijs Vogels, Octavian-Eugen Ganea, Carsten Eickhoff
2018 arXiv   pre-print
To address this issue, we introduce a novel model that performs sequence labeling to collectively classify all text blocks in an HTML page as either boilerplate or main content.  ...  Web pages are a valuable source of information for many natural language processing and information retrieval tasks.  ...  The leaves of the Collapsed DOM tree of a Web page form an ordered sequence of blocks to be labeled. For each block, we extract a number of DOM tree-based features.  ...
