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

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“

Types of Search
(1) Pinpoint-Search (factual knowledge) i.e. „Eyjafjallajökull“
(2) Collecting and Research i.e. „volcanoes in Iceland“
(3) Associative Search / Discovery of interrelations i.e. Volcanic eruptions and climate change
(4) Questions & Answers i.e. „Which volcanoes in Iceland erupted in 2010?“
(5) Serendipity Discovery of unexpected, but relevant contexts and coherences
Learning /Navigating Search

Four demands for a smarter search
Find information faster  Provide search assistants
Reveal hidden information  Enrich the search index with background knowledge
Find more specific information Query the semantic web
Find linked information Integrate data sources

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.

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

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

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

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

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

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

Find more specific information – Status quo Goldman Sachs Search
3 different contexts for
„ Goldman Sachs“:
Bond issuer
Analyst
Stock
I want to know more about this entity in a certain context.

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

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

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.

360 O views: Find linked information Energy-related information about countries are „mashed“ automatically by using „linked data“ http://www.reegle.info/countries

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

The role of thesauri in semantic search How vertical search can benefit from knowledge models http://www.flickr.com/photos/techburst/2796421248/

The role of thesauri in semantic search

The role of thesauri in semantic search (contd.)
Thesaurus as the central point
to control:
labels & query expansion
facets
refine search mechanisms
metadata integration
