| Abstract | The world of mathematical knowledge on the WWW has grown enormously. Despite the clear importance of a mathematical search engine this research field had been abandoned until very recently. Although, currently available full text search engines can be used on these documents too, they are deficient in almost all cases. They cannot handle structured mathematical text and mathematical operations. Many problems are the result of the mathematical nature. By applying axioms, equal transformations, and by using different notation each formula can be expressed in numerous ways. Ambiguous searches like "sin" or "a" would return documents containing sine function and the English noun sin or documents containing variable a and indefinite article a. Moreover, mathematical operators and special notation cannot be expressed in their query languages. In this work, we address these issues and present a technique how to index real-world scientific documents containing mathematical notation by exploiting the current state-of-art of full text search engines. Our approach has several advantages over existing solutions. It is primarily intended for documents on the WWW, which are mostly semantically poor, and offers an extensible level of mathematical awareness supporting also similarity searches. Furthermore, it is designed as an extension and therefore any full text search engine can easily adopt it. The experiments over two real-world document sets showed that the performance is highly dependent on several features of the mathematical search engine. |

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.
