Whozat’s relevance ranking makes a difference
It’s not enough to be a semantic engine that understands the meaning of queries. Whozat also ranks search results for their relevance to the query. Say you’re searching for the American Automobile Association. A semantic engine without relevance ranking returns a Wikipedia article about the AAA as its top result. The AAA’s site is not among the top 20 results at all. Whozat, in contrast, returns the AAA’s website as #1 –in addition to a Wikipedia article about it.
