Abstract The OWL Web Ontology Language is designed for use by applications that need to process the content of information instead of just presenting information to humans. 1. 2. 3. 10 More Semantic Apps to Watch. In November 2007, we listed 10 Semantic apps to watch and yesterday we published an update on what each had achieved over the past year.
All of them are still alive and well - a couple are thriving, some are experimenting and a few are still finding their way. Now we're going to list 10 more Semantic apps to watch. These are all apps that have gotten onto our radar over 2008. We've reviewed all but one of them, so click through to the individual reviews for more detail. It should go without saying, but this is by no means an exhaustive list - so if we haven't mentioned your favorite, please add it in the comments. BooRah BooRah is a restaurant review site that we first reviewed earlier this year. BooRah also announced last month the availability of an API that will allow other web sites and businesses to offer online reviews and ratings from BooRah to their customers. Swotti Swotti is a semantic search engine that aggregates opinions about products to help you make purchasing decisions.
Is Keyword Search About To Hit Its Breaking Point? As the Web swells with more and more data, the predominant way of sifting through all of that data—keyword search—will one day break down in its ability to deliver the exact information we want at our fingertips. In fact, some argue that keyword search is already delivering diminishing returns—as the slide above by Nova Spivack implies. Spivack is the CEO and founder of semantic Web startup Radar Networks and is pushing his view that semantic search will help solve these problems. But anyone frustrated by the sense that it takes longer to find something on Google today than it did even a year ago knows there is some truth to his argument. “Keyword search is okay,” he says, “but if the information explosion continues we need something better.”
Today, there are about 1.3 billion people on the Web, and more than 100 million active Websites. At a certain point, with billions and billions of Web pages to sift through, keyword search just won’t cut it anymore. Spivack explains: Towards Next Generation URLs. Great illustration of the benefits of Chunking.
