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 to error correct extant electronic documents is disclosed. An electronic document may be rasterized to obtain a pixel representation of the electronic document (e.g., raster image). One or more optical character recognition (OCR) tasks may be performed on the raster image of the electronic document. Errors discovered by the OCR tasks may be corrected and a customized error corrected version of the electronic document may be created and stored. If the author of the electronic document is known, the raster image may be compared to a personalized tf*idf error dictionary associated with the author to determine known OCR errors specific to the author. The raster image may also be compared to a personalized electronic error dictionary associated with the author to determine known typographical errors specific to the author.
摘要翻译：公开了一种错误纠正现有电子文档的系统和方法。电子文档可以被光栅化以获得电子文档的像素表示（例如，光栅图像）。可以在电子文档的光栅图像上执行一个或多个光学字符识别（OCR）任务。可能会纠正由OCR任务发现的错误，并且可以创建和存储电子文档的定制错误更正版本。如果电子文档的作者是已知的，则光栅图像可以与与作者相关联的个性化tf * idf错误字典进行比较，以确定作者特有的已知OCR错误。也可以将光栅图像与与作者相关联的个性化电子错误字典进行比较，以确定作者特有的已知印刷错误。
