7 semantic search engines

Published by admin on November 3rd, 2009 | Tagged Business, Internet and Web 2

Semantic search is being called the next big and new thing in the field of online search.

Traditional search engines ( eg: Yahoo, Live etc) focus on keywords and use ranking algorithms to give results. Semantic search engines give importance to concepts like Natural Language Processing to present more accurate and relevant pages. The aim of Semantic Search Engines is to unlock or identify the actual meaning of the search query. For example when the user searches for something like “build strong abs”, the semantic search engine may generate results with “pilate” and “yoga” information, even though these pages may not have “build strong abs” keywords.

Here is list of some popular semantic search engines:

1. Hakia

General Purpose Semantic Search Engine Hakia concentrates more on quality than the popularity of the information sources. Hakia’s technology focuses on 3 things: a) relevant results b) latest information available and c) results form credible sources.

2. Powerset

    Hey. Very cool article. Where does http://www.wolframalpha.com fit into all this semantic trend development.

    @Chris I feel Wolframalpha is a computational knowledge engine. The above mentioned services focus more on internet search for finding relevant pages.

    This is timely article. The next decade of this century will be a decade when semantic-based solutions start to become dominant. One semantic, social, real-time search engine that searches tweets TipTop at http://FeelTipTop.com is also worthy of attention. We believe that TipTop has a great future ahead in this growing field.
