  2. 2. © Semantic Web Company - http://www.semantic-web.at/ and http://www.poolparty.biz/ Key questions in this talk ● Beyond precision and recall: What makes a ‘good’ search? ● Beyond document search: What other types of ‘semantic search’ exist? ● Beyond search: What other use case scenarios than ‘search’ benefit from linked data and knowledge graphs? 2
  3. 3. © Semantic Web Company - http://www.semantic-web.at/ and http://www.poolparty.biz/ Connotation of ‘semantic’ From: Wortschatz Leipzig - http://wortschatz.uni-leipzig.de/ 3
  4. 4. © Semantic Web Company - http://www.semantic-web.at/ and http://www.poolparty.biz/ Some facts and figures Vertical search & Enterprise search: ● Currently 201 ‘Semantic Search’ Startups (https://angel.co/semantic-search) ● Around US$ 900 million of venture capital Web search: ● Wikipedia’s pageviews declined 21% the year after Google Knowledge Graph was launched ● Google search volume for json-ld 4
  5. 5. © Semantic Web Company - http://www.semantic-web.at/ and http://www.poolparty.biz/ Diverse promises made by ‘Semantic Search’ vendors Use Weotta and get inspired. Search is outdated. Google steers you to right section of the library, but doesn’t answer your question or compile that answer with others to help you make a decision. Ambiance can automatically match the meaning of the page to the products that are most contextually relevant in real time. Benefit from additional insights through interactive visualizations of reports and search results derived from your data lake 5
  6. 6. © Semantic Web Company - http://www.semantic-web.at/ and http://www.poolparty.biz/ So, what is ‘Semantic Search’? It’s all about improved user experience, no matter how complex information procurement is: I am a web shopper. I want to have nice buying experiences when using an online shop. I am a doctor. I need a 360- degree view on my patient. I don’t have the time to search around. 6
  7. 7. © Semantic Web Company - http://www.semantic-web.at/ and http://www.poolparty.biz/ Semantic Search is about precise contextualization (personalisation) Semantic search engines are able to link entities in a meaningful way. They extend graphs ‘on-the-fly’ by reusing already existing knowledge graphs. “Which skateboard fits to my jacket and its manufacturer also produces snowboards?” “Which new medical studies about allergy ABC talk also about symptoms related to my current patient?” 7
