  3. 3. Introduction <ul><li>Since 25 years : user-centered revolution ( people/user oriented, people centered, user based, human centered, user responsive and so on...) in differents fields </li></ul><ul><li>Focus on beneficiaries of services </li></ul><ul><li>Is it « an amalgam of methods, approaches, techniques which help to define, understand, explain measure and finally serve the need of people. » </li></ul><ul><li>LIS and KO field also concerned, one of their aim is to help the user </li></ul>
  4. 4. Behaviour of the user in information seeking <ul><li>Importance of the context and environment of the research (time, state of mind..)‏ </li></ul><ul><li>The process of searching is dependant of the implication and motivation of the searcher (for him, ask by his boss...)‏ </li></ul>
  5. 5. Thesauri in information searching <ul><li>User need to understand the structure before using, so not useful tool for untrained &unregular searchers </li></ul><ul><li>Blocks, Dorothée made a survey in 2004 to show how user interact with thesauri </li></ul><ul><li>Importance of errors and problematic situations: </li></ul><ul><ul><li>to redesign system in order to avoiding problems </li></ul></ul><ul><ul><li>to show the importance of user support </li></ul></ul>
  6. 6. Trends on World Wide Web <ul><li>Thesaurus </li></ul><ul><ul><li>Developers try to make their thesauri available for Internet and created user-friendly interface </li></ul></ul><ul><ul><li>Role of thesaurus changing: more used for retrieval than for imputing </li></ul></ul><ul><ul><li>With growth of information: need of tools for retrieval and thesaurus better than web search engines </li></ul></ul><ul><ul><li>Lack of standards for publishing thesauri on the Web: variety of formats, problems of interoperability, shareability... </li></ul></ul>
  7. 7. Trends on World Wide Web <ul><li>Collaborative Tagging (Floksonomy, social classification, social indexing/tagging...)‏ </li></ul><ul><ul><li>Web 2.0: user also creator and engage in information organisation </li></ul></ul><ul><ul><li>Challenging traditional KO </li></ul></ul><ul><ul><li>Definition: «  collaboratively creating keywords (tags) to annotate and categorize content » </li></ul></ul><ul><ul><li>« Floksonomy is a classification of the users, by the users and for the users. » </li></ul></ul>
  8. 8. Collaborative Tagging <ul><li>The indexing process </li></ul><ul><ul><li>Contrary to KO the indexer could be also the creator </li></ul></ul><ul><ul><li>Jakob Voss: At least 4 differents agents: Ressource author, Ressource collector, Indexer or tagger, Searcher </li></ul></ul><ul><ul><li>Free vocabulary </li></ul></ul><ul><ul><li>Popularity of tag determined by their level of use: tag cloud </li></ul></ul>
  9. 9. So different but must be complementary <ul><li>Lots of problems with tagging (level of expertise, kind of tags, synonyms...): </li></ul><ul><ul><li>Begining, not yet understand they should follow conventions </li></ul></ul><ul><ul><li>Must be help by thesaurus which can avoid these difficulties about choice of term </li></ul></ul><ul><li>But reals advantages </li></ul><ul><ul><li>Economic: indexing with controlled vocabulary really costly in time and efforts </li></ul></ul><ul><ul><li>Social and interactive aspect: share and categorize information fo others </li></ul></ul>
  10. 10. Conclusion <ul><li>Knowledge Organisation exists since a long time and evoluated with society and the needs of users </li></ul><ul><li>With new electronic environment: emphasizing on its importance (amount of information) but also challenged (new systems)‏ </li></ul><ul><li>Professionals of KO, designers and creators of tagging system should work together to serve as much as possible theinformation need of people </li></ul>
