| Abstract | A key step in the evolution of a Java system towards the aspect oriented paradigm is the identification of crosscutting concerns that need to be refactored. This paper proposes an approach to identify concerns and the crosscutting among them in existing Java systems. A meta-model is defined to represent concerns as sets of Type Fragments (where a Type Fragment is a portion of a Type in terms of its members, properties and relationships). The approach exploits the concept of Role: each Role is associated to a concern and the system source code is analyzed to find the Type Fragments implementing it. All the Roles that contribute to implement a same semantic concern are grouped together by a clustering algorithm based on a combination of a structural and a lexical distance. Each cluster of Roles (and thus the Type Fragments associated to them) is assigned to a single more abstract concern. Crosscutting is detected looking for scattering and tangling of Type Fragments within the identified concerns. The structural information about the Type Fragments assigned to each concern and the crosscutting relationships among the concerns can be used to drive the refactoring towards aspects. The results from a case study where the approach has been applied to several software systems are presented and discussed. |

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.
