  abstract = {Social tagging systems have shown an impressive potential for information discovery and exploration. Enriched with Semantic Web technologies, they enable to tap valuable metadata about Web resources and to detect hidden relations, thus, to capture information about both content and context of the resources. In this article, we propose a novel way to combine semantic technologies with Web 2.0 paradigms. We introduce the GroupMe! system, which extends current social tagging systems by giving users more flexibility in organizing and maintaining Web content. In GroupMe!, users can create groups of Web resources they consider relevant by simple drag & drop operations. They can tag and share their groups and Web content with fellow users and benefit from improved search and retrieval capabilities. We evaluate the GroupMe! approach and investigate on the effect of grouping resources for search in tag-based social systems. Our experiments show that the quality of search result ranking can be significantly improved by introducing and exploiting the grouping of resources. },

@inproceedings{Zanardi:2008yq,
  abstract = {Social (or folksonomic) tagging has become a very popular way to describe, categorise, search, discover and navigate content within Web 2.0 websites. Unlike taxonomies, which overimpose a hierarchical categorisation of content, folksonomies empower end users by enabling them to freely create and choose the categories (in this case, tags) that best describe some content. However, as tags are informally defined, continually changing, and ungoverned, social tagging has often been criticised for lowering, rather than increasing, the efficiency of searching, due to the number of synonyms, homonyms, polysemy, as well as the heterogeneity of users and the noise they introduce. In this paper, we propose a method to increase the efficiency of searches within Web 2.0 that is grounded on recommender system techniques. We measure users' similarity based on their past tag activity. We infer tags' relationships based on their association to content. We then propose a mechanism to answer a user's query that ranks (recommends) content based on the inferred semantic distance of the query to the tags associated to such content, weighted by the similarity of the querying user to the users who created those tags. We evaluate the effectiveness of this mechanism when performing searches on the CiteULike dataset.

  abstract = {This paper examines the use of non subject related tags in three social bookmarking tools (Del.icio.us, Connotea and Citeulike). Previous studies of Del.icio.us and Citeulike determined that many common tags are not directly subject related but are in fact affective tags dwelling on a user's emotional response to a document or are time and task related tags related to a users current projects or activities. A set of non subject tags from the previous studies was used to collect posts with non subject tags from the three listed social bookmarking tools. These tags have been analysed to examine their role in the tagging process. },
