| Abstract | Defining semantic functional similarity measures provides effective means to validate protein function prediction methods and to retrieve biologically relevant information from big biological data. It also improves understanding of interrelationship between genes and gene products (GPs). Currently, one of the most commonly used tools for functionally annotating genes and GPs is the Gene Ontology (GO), which describes genes/GPs using a machine-readable language. To measure the semantic similarity between two GO terms, many studies that are based on GO topology have recently been reported. However, a comprehensive assessment and general guidelines for validating these methods are lacking. In this paper, we collect a large dataset to evaluate five often-used semantic similarity measure methods by estimating sequence similarity, phylogenetic profile similarity, and structural similarity. We further compare the measures in terms of their clustering performance using domains extracted from SCOP database. We describe some key aspects of these measure methods and discuss how the limitations may be addressed as well as some open problems. |

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.
