1. Miruna Bădescu Eau de Web CHM Workshop in Bucharest 13-14 December 2010 CHM controlled vocabulary - what is involved -

2. 2 Which are the steps 1.Building and translating the controlled vocabulary 1.Agree on the list of terms 2.Incorporate translations from the countries 2.Tagging the content 1.Use a new field besides “keywords”? 2.Change the GUI to easily browse the vocabulary 3.Auto-complete 4.Autosuggest? 3.Improving the searches 1.Pick words for searching 2.Multilingual searches – display the content tagged with the term or its translations 4.Syndication 1.Provide support in the PTK for feeds of content that contain a keyword 2.Multilingual feeds 3.Provide help for CHMs not using the PTK

3. 3 1. Building and translating the controlled vocabulary  First version already done by Rob  Translations available in fr, nl, ro, ee, de  Issues:  Obtain as many translations as possible for the exercise  Keep the terms updated on national portals in longer term  Distribute the list of terms for countries not using the PTK

4. 4 2. Tagging the content (1)  Having a separate field for the controlled vocabulary terms?  Today’s demonstration assumes so  Pro: clarity and improved system speed, con: more work for the content provider  Autosuggest - i.e. trying to identify the terms based on the current content – not practical, as the terms contain multiple words

5. 5 2. Tagging the content (2)  Autocomplete  Display a list of terms that contain the typed letters, regardless of where they appear in the words

6. 6 2. Tagging the content (3)  Better browsing of the vocabulary  Replace the old popup window with a bigger overlay space in the same window  Allow an easy inspection and search of the entire glossary

7. 7 3. Improving the searches (1)  Allow users to search by the same terms that are introduced by the content providers  Example from semide.net:

8. 8 3. Improving the searches (2)  Other improvements:  Display a “tag cloud”, although the terms of our glossary are not atomic words, but phrases  If keywords were picked from the glossary/vocabulary, search for content that contains the translation(s) of the keywords

9. 9 4. Syndication (1)  Changes in the European PTK (proposal):  Feeds and corresponding portlets will become available for the aggregation of the content tagged with a certain keyword  On folders tagged with a keyword, the above right- side portlets will automatically appear  Separation of these feeds based on language  Help for the CHM nodes not using the PTK:  A manual for providing feeds in RSS/RDF/ATOM formats will be distributed  Other formats protocols can be included later, for the first exercise we want to keep things simple  Specific helpdesk for the country developers in order to build these feeds on their own platforms

10. 10 4. Syndication (2)  Regional/global portals (e.g. the EC CHM, cbd.int) will be able to aggregate thematic feeds from the countries  Examples:  Upcoming events for “Status of threatened species”  Latest news on “Coverage of protected areas”  Recent publications on “Climate change”
