| Abstract | To determine which documents are relevant and which are not to the user query is one central problem broadly studied in the field of information retrieval (IR). Learning to rank for information retrieval (LR4IR), which leverages supervised learning-based methods to address the problem, aims to produce a ranking model automatically for defining a proper sequential order of related documents according to the given query. The ranking model is employed to determine the relationship degree between one document and the user query, based on which a ranking of query-related documents could be produced. In this paper we proposed an improved RankGP algorithm using multi-layered multi-population genetic programming to obtain a ranking function, trained from collections of IR results with relevance judgments. In essence, the generated ranking function is consisted of a set of IR evidences (or features) and particular predefined GP operators. The proposed method is capable of generating complex functions through evolving small populations. LETOR 4.0 was used to evaluate the effectiveness of the proposed method and the results showed that the method is competitive with RankSVM and AdaRank. |

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.
