    摘要: A computer-implemented method for obtaining the rendering co-ordinates of visible text elements on a web page is disclosed. The web page is represented by an input data structure comprising a plurality of text nodes, each of which represents a text element on the web page. The method comprises the following steps: a) using a computer device, wrapping each of the plurality of text nodes in a pair of mark-up language tags; b) using said computer device, obtaining the co-ordinates of a bounding rectangle for each text node using the mark-up language tags; c) using said computer device, attaching an attribute specifying the co-ordinates of the bounding rectangle to each text node; and d) using said computer device, determining whether each text node is invisible, and if it is, excluding it from an output data structure comprising the plurality of text nodes and attached attributes.

    摘要: A method and system for extracting Web content is disclosed. In one embodiment, Web content in a Webpage is extracted by identifying paragraphs in the Web content based on line-break node determination. A range of text-body associated with the identified paragraphs is then identified using a maximum scoring subsequence. Further, the identified text-body is refined using a heuristic rule of substantially horizontal alignment. Furthermore, one or more titles and one or more images associated with the Web content are extracted. Moreover, the Web content including the identified paragraphs, the one or more titles and the one or more images are outputted.

    摘要: A system and method are provided for extracting main content from a web page. Web page segmentation is performed on a web page to provide affinity-grouped segments. Descriptive features of at least one of the affinity-grouped segments are computed. At least one of the affinity-grouped segments is classified as a main body segment based on the computed descriptive features. Additional affinity-grouped segments are classified as to a document function based on the computed descriptive features. Classified affinity-grouped segments are assembled according to their classified document functions to provide the main content.

    摘要: A system and method of detecting separator lines in a web page may include determining coordinates of visible web elements on a web page, generating an edge image of the web page based on the coordinates of the web elements, filtering edges belonging to non-separator line elements within the edge image, detecting horizontal lines within the edge image, detecting vertical lines within the edge image, and filtering short lines within the edge image. A system for detecting separator lines in a web page may include a memory device, and a processor communicatively coupled to the memory, in which the processor determines coordinates of visible web elements on a web page, generates an edge image of the web page based on the coordinates of the web elements, filters edges belonging to non-separator line elements within the edge image, detects horizontal lines within the edge image, detects vertical lines within the edge image, and filters short lines within the edge image.
