| Abstract | The identification of drug-target interactions in web lab is costly and time-consuming. Computational approaches become important to help identifying potential candidates for laboratory experiments. However, they usually involve solving optimization problems or assuming statistical distribution based on prior knowledge, and may require estimating tunable parameters. This paper is motivated by the concepts behind “follow-on” drugs. They are the drugs developed by drug companies to substitute the pioneering drug which was firstly discovered and patented for a specific target and determined a new therapeutic class. There are three observations from “follow-on” drugs. The first observation has been used by many existing methods: drugs interacting with a common target usually have higher similar scores (e.g. the similarity score in terms of chemical structure). The second one is that a drug candidate for a specific target gains more attention if it is more similar to those drugs interacting with the target than other known drugs, even though the similarity score is low. Lastly, people intuitively tend to design a “follow-on” drug for the targets already having more drugs because of less cost and less risk. In our approach, the above observations are translated into more evidences for predicted drug-target interaction. Designing an interaction tendency index to characterize these observations, we propose the similarity-rank-based predictor (SRP). Unlike other models, SRP is a non-parametric model and requires neither solving an optimization problem nor prior statistical knowledge. Based on real benchmark datasets, we show that our model is able to achieve higher accuracy than the two most recent models and our approach is able to cope with two real predicting scenario of missing interactions. |

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.
