2009 Horizon Report " Four to Five Years: Semantic-Aware Applications. Time-to-Adoption Horizon: Four to Five Years The idea behind the semantic web is that although online data is available for searching, its meaning is not: computers are very good at returning keywords, but very bad at understanding the context in which keywords are used. A typical search on the term “turkey,” for instance, might return traditional recipes, information about the bird, and information about the country; the search engine can only pick out keywords, and cannot distinguish among different uses of the words. Similarly, although the information required to answer a question like “How many current world leaders are under the age of 60?” Is readily available to a search engine, it is scattered among many different pages and sources.
The search engine cannot extract the meaning of the information to compile an answer to that question even though it can return links to the pages that contain pieces of that answer. Overview Research. Examples of Semantic-Aware Applications. 10 Semantic Apps to Watch. One of the highlights of October's Web 2.0 Summit in San Francisco was the emergence of 'Semantic Apps' as a force.
Note that we're not necessarily talking about the Semantic Web, which is the Tim Berners-Lee W3C led initiative that touts technologies like RDF, OWL and other standards for metadata. Semantic Apps may use those technologies, but not necessarily. This was a point made by the founder of one of the Semantic Apps listed below, Danny Hillis of Freebase (who is as much a tech legend as Berners-Lee).
The purpose of this post is to highlight 10 Semantic Apps. We're not touting this as a 'Top 10', because there is no way to rank these apps at this point - many are still non-public apps, e.g. in private beta. What is a Semantic App? Firstly let's define "Semantic App". In September Alex Iskold wrote a great primer on this topic, called Top-Down: A New Approach to the Semantic Web. Freebase Powerset Powerset (see our coverage here and here) is a natural language search engine.
