| Abstract | In this paper, we address the challenges that arise from the growing scale of annotations in scientific databases. On one hand, end-users and scientists are incapable of analyzing and extracting knowledge from the large number of reported annotations, e.g., one tuple may have hundreds of annotations attached to it over time. On the other hand, current annotation management techniques fall short in providing advanced processing over the annotations beyond just propagating them to end-users. To address this limitation, we propose the InsightNotes system, a summary-based annotation management engine in relational databases. InsightNotes integrates data mining and summarization techniques into annotation management in novel ways with the objective of creating and reporting concise representations (summaries) of the raw annotations. We propose an extended summary-aware query processing engine for efficient manipulation and propagation of the annotation summaries in the query pipeline. We introduce several optimizations for the creation, maintenance, and zoom-in processing over the annotations summaries. InsightNotes is implemented on top of an existing annotation management system within which it is experimentally evaluated using real-world datasets. The results illustrate significant performance gain from the proposed techniques and optimizations (up to 100x in some operations) compared to the naive approaches. |

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.
