    2. 2. Gateways and Tematic Portals <ul><li>Centered in an especific subject </li></ul><ul><li>Activity and uses are oriented to a user community </li></ul><ul><li>Offering: </li></ul><ul><ul><li>Own information </li></ul></ul><ul><ul><li>Referenced information </li></ul></ul><ul><li>User services are developed around the information content </li></ul>
    3. 3. Information Organization <ul><li>A collection is organized </li></ul><ul><li>Collection is focused with criteria that the users can understand </li></ul><ul><li>Adopts the “bibliography metaphor” </li></ul><ul><li>The first approach is hierarchical </li></ul><ul><li>The user has the “search” and “browse” options to access to the collection content </li></ul>
    4. 4. Gateway as digital information space <ul><li>A gateway is a digital information space </li></ul><ul><li>It’s a complex context, where interact information management, information design, human-computer interaction, cognitive psycology... </li></ul><ul><li>User is the King: gateways must be constructed thinking in user objectives; this way, classifications are for the user </li></ul>
    5. 5. Classification <ul><li>Creation or adoption of controlled vocabularies / classification systems </li></ul><ul><li>Designed for offer thematic access </li></ul><ul><li>Systems and schemes thought by humans </li></ul><ul><li>Systems and schemes applied by humans </li></ul><ul><li>Tendency to automatic classification </li></ul>

    8. 8. New approaches <ul><li>Automatic classification </li></ul><ul><li>Ontologies </li></ul><ul><li>Semantic web </li></ul><ul><li>In this moment classifications, subject headings/keywords and thesaurus are applied; ontologies and semantic web are still experimental </li></ul>
    9. 9. User behavior <ul><li>Tends to desintermediation </li></ul><ul><li>User has a clear objective, with proper definition and classification </li></ul><ul><li>Must learn the gateway criteria for organization, classification, exploration and retrieval </li></ul><ul><li>Must adequate its cognitive scheme to the cognitive scheme subyacent to the gateway applied classification </li></ul>
    10. 10. User problems <ul><li>Heterogeneus interfaces </li></ul><ul><li>Different classifications, in the same subject areas </li></ul><ul><li>Dificulties to combine classifications with descriptors/keywords </li></ul><ul><li>Different performances of the gateways search systems </li></ul><ul><li>Different levels of description and evaluation of referred resources </li></ul>
