| Abstract | Departments of organizations such as companies and universities tend to publish various information on their own Web sites. For example, descriptions of the members of a certain laboratory at a university may appear on the laboratory's Web site, the department's Web site, and so on. However, inconsistencies may occur between descriptions on these sites if their update timings and management policies are different. It is not easy to find such inconsistencies on large-scale Web sites, and the maintenance costs of doing so are huge. Record linkage techniques, which determine if two entities represented as relational records are approximately the same, have been developed as ways of identifying whether two entities are approximately the same. The current methods focus on simple objects, that are represented by individual records. But objects often consist of numerous simple objects; namely, they are often compound objects. For example, a research team object may contain several researcher objects. In this case, the research team object is a compound object, and the individual researcher objects are simple objects. The current record-level linkage methods can't detect such compound objects correctly when a record of one compound object doesn't match the record of the other. We propose novel methods of linking compound objects for supporting maintenance of large-scale Web sites. We first extract the relational records of Web objects by exploiting the structure of the Web pages they are on and the linguistic features of their descriptions. To find linkable compound objects that are constituted of simple objects, after the record-level linkage, we look at the compound objects' features, i.e., records continuity, common attribute values, and co-occurrences. Experimental results show that our method can detect compound objects that can't be detected by making only record-level linkages. |

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.
