The objective of this paper is to investigate the effectiveness of tags in facilitating resource discovery through machine learning and user-centric approaches. Drawing our dataset from a popular social tagging system, Delicious, we conducted six text categorization experiments using the top 100 frequently occurring tags.

Public sector bodies hold a significant amount of data that might be of potential interest to citizens and businesses. However the re-use potential of this data is still largely untapped because the data is not always published in a way that would allow its easy discovery, understanding and re-use. Open Government Data (OGD) initiatives aim at increasing availability of machine-readable data pr...

In this paper we present an unconventional image segmentation approach which is devised to meet the requirements of image understanding and pattern recognition tasks. Generally image understanding assumes interplay of two sub-processes: image information content discovery and image information content interpretation. Despite of its widespread use, the notion of “image information content” is st...

KEYWORDS The terms 'unified index' and 'unified search index' libraries are getting associated with discovery services. Discovery services are that unified search index to search content from all sources they have access to from a single index. It ia single and simply entry point which searches the single entry point which searches the pre-indexing metadata and fulltext documents. Similarly web...
