Jim Hendler discusses the growth and implications of the Semantic Web, emphasizing its potential to revolutionize web interactions through linked data and enhanced search capabilities. He highlights the evolution from basic web functionality to more complex, semantically rich applications, with examples such as schema.org and IBM's Watson. The document also touches on the challenges of business models and the integration of semantic technologies in various sectors.

- 10. Linked Data is entering many sectors Linkeddata.org 37 billion links
- 11. Linked Data + Semantics "Linked Data" approach finds its use cases in Web Applications (at Web scales) A lot of data, a little semantics Finding anything in the mess can be a win! http://www.cs.rpi.edu/~hendler/LittleSemanticsWeb.html

- 13. Semantic Web What is driving the change? Maturation of RDF technologies SPARQL endpoints Embedded markup Schema.org & RDFa Lightweight Knowledge A little semantics goes a long way
- 14. Maturation of the “bottom” of the Semantic Web What is seeing the most use?? RDFa

- 33. Which may be a feature Significant and growing commercial interest… Web: Google, Amazon, Travelocity… Web 2.0: Facebook, Wikipedia, YouTube, Twitter… Web 3.0: ??
- 34. Summary The Semantic Web is real People asking “how,” not why So far the commercial driver has been “weak semantics” Very Simple “ontologies” Lots of linking Metadata agreements, not ontology alignments Web 3.0 adds semantics as a value add to regular Web functionality Data mashup Semantic search Semantic match Investor excitement: The big one is still out there
- 35. Your Questions Were Requested Session Focus My internal contacts here at Nuance have requested a basic introduction on semantic web, with the discussion biased toward two use cases: Question answering by machine “ When does home depot close?” “ Who has tylenol on sale?” “ Where is the nearest shoe store that carries Rockport?” (See Semantic Search) Automated agents “ Buy two tickets to the Patriots Jets game.” “ Reorder Bond Street English Breakfast from Upton Tea.” “ Find the lowest price on a Canon 70 to 200 f4 IS lens and email me the link.” (Discuss Siri)
