| Abstract | Web Data Management (or WDM) refers to a body of work concerned with leveraging the large collections of structured data that can be extracted from the Web. Over the past few years, several research and commercial efforts have explored these collections of data with the goal of improving Web search and developing mechanisms for surfacing different kinds of search answers. This work has leveraged (1) collections of structured data such as HTML tables, lists and forms, (2) recent ontologies and knowledge bases created by crowd-sourcing, such as Wikipedia and its derivatives, DBPedia, YAGO and Freebase, and (3) the collection of text documents from the Web, from which facts could be extracted in a domain-independent fashion. The promise of this line of work is based on the observation that new kinds of results can be obtained by leveraging a huge collection of independently created fragments of data, and typically in ways that are wholly unrelated to the authors' original intent. For example, we might use many database schemas to compute a schema thesaurus. Or we might examine many spreadsheets of scientific data that reveal the aggregate practice of an entire scientific field. As such, WDM is tightly linked to Web-enabled collaboration, even (or especially) if the collaborators are unwitting ones. We will cover the key techniques, principles and insights obtained so far in the area of Web Data Management. |

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.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
