| Abstract | Despite the large amount of multimedia content in Web 2.0 applications, most of its services in Information Retrieval (IR) use only attributes associated with textual content (eg, labels or tags). However, because they are typically generated by users, such attributes do not offer guarantees of quality for IR services. Here, we investigate evidence of quality of textual attributes in popular Web 2.0 applications related to three aspects: utilization; discriminative and descriptive power. We have performed a characterization of the use of four textual attributes (title, description, tags and comments) in the following systems: Youtube, YahooVideo, LastFM and CiteULike. Some of our results, which may be considered in the design of IR services in Web 2.0, are: (1) collaborative textual attributes, although not significantly exploited in some applications, contain the largest amount of information when present, (2) there is a significant diversity of information between the textual attributes, and (3) the title and tags of the objects seem to be the most promising attributes for IR services, whereas the former is almost always present and has a high power specification, and second, when used, has a high discriminative and descriptive power. |

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.
