| Abstract | The performance of automatic web service composition in massive service candidate collection behaves badly when running inappropriate strategy on whole candidate collection. A new service composition model is proposed to solve this problem. The model formally describes web service via ontology technique, which can easily get the user's demand. The paper first defines the cost to satisfy user's requirement, then finds out most similar web services, and constructs the directed acyclic graph based on cost by composition cost relations of web services. At last,the system applies depth first service search algorithm on the graph to find an optimal composition component. The results of experiment proved that this model have high composition efficiency and high success ratio. |

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.
