| Abstract | A publication record denotes a list of semi-structured citation string of publications of a research institute or an individual researcher. Publication records are integrated into a digital library to become an important knowledge base which in turn enables a variety of applications. A publication record is usually found among other information on a publication Web page (or publication page for short). It is thus an interesting problem to extract publication record from these Web pages. The problem is difficult due to several reasons including the flexibility in formatting the metadata of a publication into a semi-structured citation string and expressing the citation string into its visual presentation in HTML. Furthermore, two citation strings with similar visual presentation on the same Web page may have different HTML constructs. In this paper, we present a content analysis approach based on Conditional Random Fields and data region boundary analysis to automatically extract citation record on a publication page. Experimental results show that our method performs well on a benchmark containing manually crafted publication Web pages. The precision, recall, and F-measure are 82.5%, 87.6%, and 85.0% respectively. This is an improvement over previous results. |

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.
