| Abstract | Cross Language News story search (CLNSS) is concerned with finding documents describing the same events in documents in different languages. As well as supporting information retrieval (IR), CLNSS has other applications in mining parallel and comparable data across different languages. In this paper, we present an overview of the work carried out for our participation in the Cross Language !ndian News Story Search (CL!NSS) task at FIRE 2013. In the CL!NSS task we explored the problem of cross language news search for the English-Hindi language pair. English news stories are used as queries to seek similar news documents from Hindi news articles. Hindi being a resource-scarce language offers many challenges towards retrieving relevant news articles. We investigate and contrast translation of input queries from English to Hindi using the Google and Bing translation services. To support translation of out-of-vocabulary words we use the Google transliteration service. A key challenge of the CL!NSS task is formation of search queries from the English news articles, since they are much longer than the much shorter queries typically used in IR applications. To address this problem, we explore the use of summarization to extract a query from the input news documents, and use these summarized queries as the input to the cross language IR system. We explore the use of query expansion using pseudo relevance feedback (PRF) in the IR process, since this has been shown to be effective for cross language IR in many previous investigations. We also explore in detail the use of data fusion techniques over different sets of retrieved results obtained using diverse query formulation techniques. For the CL!NSS task our team submitted 3 main runs. The results of our best run was ranked first among official submissions based on NDCG@5 and NDCG@10 values and second for NDCG@1 values. For the 25 test queries the results of our best main run were NDCG@1 0.7400, NDCG@5 0.6809 and NDCG@10 0.7268. We present our methodology, official results and results of a number of post-task experiments that were conducted to further examine the cross language search problem. Our experiments reveal that query formulation plays a vital role in improving search results for news documents across different languages. Instead of using the complete news documents the summarized queries show better performance. Data fusion techniques also help to improve the performance of the system by boosting the rank of documents, thus improving the NDCG scores. |

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.
