Approximate matching of textual domain attributes for information source integration

Content Provider ACM Digital Library
Author Koeller, Andreas Keelara, Vinay
Abstract A key problem in the integration of information sources is the identification of related attributes or objects across independent sources. Inferring such meta-information from source data (rather than a-priori available meta-data, such as attribute names) is sometimes possible. For example, existing algorithms attempt to integrate information sources by finding patterns such as Inclusion Dependencies (INDs) across them. However, INDs are based on exact set inclusion and are thus very strict patterns that rarely hold across independent real-world databases.We propose two error-tolerant measures, termed Similarity Score and Distribution Score, that help identify related attributes across two independent databases, based on similarities in their data. Those measures specifically address the problem of identifying semantic relationships between textual attributes of databases that have few or no equal values.We also present implementations of those measures and some experimental results.

About National Digital Library of India (NDLI)
NDLI logo

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.
