| Abstract | Approaches to Web application adaptation can be classified based on whether the application is aware of the adaptation or not. In the latter case, adaptation is referred to as external. External adaptation requires the use of addressing patterns that locate the target portion/data on the application pages to be adapted. Unfortunately, changes on the application normally also require updates to the addressing patterns. This raises pattern robustness as a main concern. This papers focuses on the (semi) automatic generation of change-resilience XPath patterns. Two different categories of changes are addressed, i.e. in space (e.g., different personalizations of a page) and in time (e.g., site upgrades), by exploiting two different techniques: induction and simulated annealing. These techniques permit to obtain XPath patterns "resilient-enough" to a "controlled set of page designs". SiSy, a tool that assists the user in obtaining resilient XPath expressions, was born out of this approach. The approach is tested for two websites (www.yahoo.com and www.elmundo.es), identifying 23 updates to which XPath expressions were resilient to 62% of the undertaken changes. |

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.
