Abstract | A novel online news extraction approach based on human perception is presented in this paper. The approach simulates how a human perceives and identifies online news content. It first detects news areas based on content function, space continuity, and formatting continuity of news information. It further identifies detailed news content based on the position, format, and semantic of detected news areas. Experiment results show that our approach achieves much better performance (in average more than 99% in terms of F1 Value) compared to previous approaches such as Tree Edit Distance and Visual Wrapper based approaches. Furthermore, our approach does not assume the existence of Web templates in the tested Web pages as required by Tree Edit Distance based approach, nor does it need training sets as required in Visual Wrapper based approach. The success of our approach demonstrates the strength of the perception-oriented Web information extraction methodology and represents a promising approach for automatic information extraction from sources with presentation design for humans. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
