Launched as a beta in July, Yebol clusters and categorizes search terms and Websites, pages and contents rather than offering the standard list of Web search results that Google, Yahoo and Microsoft return in response to search queries.
Also, while existing semantic search engines such as Hakia and Kosmix rely on language patterns to return results, Yebol's results are powered by "human knowledge," providing what the company argues are more accurate and relevant results.
The company currently indexes 10 million semantic search terms, compared with Microsoft Bing's 6 million semantic search terms.
When Yebol launches in November (or possibly December), it will provide semantic search for every conceivable search term, something no company has done before, Yebol spokesperson Grant Landis told eWEEK recently. Moreover, when someone enters a term Yebol has never seen before into the search engine, Yebol will index the term in real time and produce complete semantic results.
The Yebol home page, which, like most search engines, includes tabs for videos, news and images, creates a customized home page for anything the user searches for. A search for "pizza" on Yebol returns related topics on the left, including different types of pizza. See the pictures on Google Watch here.
The center rail is very busy, packing in not only search results for pizza, but also news and links to pages on pizza from resources such as Wikipedia, StumbleUpon and MapQuest. These sources are in the Top Sites box at the top of the page, and it is clear that Yebol is positioning the box and its sources as a competitive differentiator.
The right-hand rail includes search options, as well as a real-time Twitter section that surfaces tweets that include the word pizza.
