| Abstract | Nowadays, vast amounts of multimedia data can be obtained across different collections (or domains). Therefore, it poses significant challenges for the utilization of those cross-collection data, for examples, the summarization of similarities and differences of data across different domains (e.g., CNN and NYT), as well as finding visually similar images across different visual domains (e.g., photos, paintings and hand-drawn sketches). In this paper, a supervised cross-collection Latent Dirichlet Allocation (scLDA) approach is proposed to utilize the data across different collections. As a natural extension of traditional Latent Dirichlet Allocation (LDA), scLDA not only takes the structural priors of different collections into consideration, but also exploits the category information. The strength of this work lies in integrating topic modeling, cross-domain learning and supervised learning together. We conduct scLDA for comparative text mining as well as classification of news articles and images from different collections. The results suggest that our proposed scLDA can generate meaningful collection-specific topics and achieves better retrieval accuracy than other related topic models. |

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.
