SerendipiTAG is a tag-based recommendation web environment designed to support users when searching for information.Based on the tags created by the users of a series of social sites and social networks, or basically tags in general, the system offers alternative search paths which increase the likelihood of a successful search and at the same time support processes of serendipity: the probability of finding results that correspond to the search in question, albeit in unexpected directions. A search for the term “content management system”, for example, yields results regarding not only the search term itself, but also related results such as Joomla, Drupal and Wordpress, three well-known CMS.The system is not independent: it is a layer that can be added to tag-based environments, whether commercial, like Flickr, or corporate. SerendipiTAG can in fact be integrated into the eCollab asset, the collaborative work platform developed by CSP..

THE MAIN FUNCTIONSThe functional benefits of SerendipiTAG are:

Predictive search suggestionswhile typing in a query, even partially, the system deduces the keywords that the search results may contain and lists the number of results for each term. The result is therefore contextualised according to a range of variables such as the user’s platform, the relevant tags, and the people that most used that tag;

Tag cloud alongside the results two tag clouds are visualised. The first represents concepts related to the search and the second shows the people with the competencies associated with the tags searched on the different platforms that SerendipiTAG is applied to. If the user clicks on a term in the first cloud, the search is refined according to the new concept, while selecting the name of a user in the second tag cloud makes the system refine the search to show only the contents inserted and tagged by that person;

Cardinality the size of the characters used for the terms shown in the tag clouds indicates the level of frequency of the term in question, thus offering an immediately legible overview in line with the communication codes that characterise social tagging and social bookmarking.

The project is a collaboration between W3Lab and DirPRO.
