This document discusses semantic search and how thesauri can improve search experiences. It describes different types of semantic searches and demands for smarter searches. PoolParty Semantic Search is presented as a solution that leverages thesauri to provide auto-complete, query expansion, faceted search, and integration of linked data from multiple sources. A live demo of PoolParty Semantic Search is available online.

3. Semantic search scenarios Semantic search has many faces http://www.flickr.com/photos/techburst/2796421248/

4. Situations in which semantic search can help I can´t remember how to spell the search term I can´t remember exactly what I was looking for I want to gain background knowledge to a certain document I want to know more about this entity in a certain context. I want to see facts from different sources describing this entity. I want to search in different languages simultaneously I forgot some of the names for the entity I´m looking for I want the software to understand what I mean by „Jaguar“

7. Find information faster – Auto-Complete I can´t remember how to spell the search term To provide powerful auto-complete also for enterprise search scenarios you need to establish an enterprise vocabulary.

8. Find information faster – Status quo hydropower plants Search I can´t remember exactly what I was looking for Small hydro Search

9. Find information faster with related search terms hydropower plants Search http://www.reegle.info/clean-energy-search

10. Reveal hidden information – Status quo SNCR Search SNCR OR „Selective non- Search I forgot some of the names for the entity I´m looking for

11. Reveal hidden information with query expansion SNCR Search OR "selective non catalytic reduction" SNCR selective non catalytic reduction alternative Label preferred Label

12. Multi-lingual search based on a thesaurus clean energy Search OR energía limpia clean energy energía limpia preferredLabel @es preferred Label @en I want to search in different languages simultaneously

13. Reveal hidden information and relations Find documents or images related to any other text. http://poolparty.punkt.at/demozone I want to gain background knowledge to a certain document

15. Find more specific information with faceted search facets support structured queries facets help to drill down search results, adapt dynamically Zero-result queries won´t happen anymore

16. Complex queries with faceted search over linked data „ Show me all airlines whose parent company is Lufthansa“ http://dbpedia.neofonie.de/

17. Find linked information – Status quo My Energy-Dossier about I want to see facts from different sources describing this entity. The user has to put together manually energy-related information about a country.

19. Add personal context to the search I want the software to understand what I mean by „Jaguar“ Jaguar Search
