Semantic Search Engines

“Semantic” is a word with a magic ring to it in search of engine circles. The way it’s hyped makes you suspect it is the second coming of search Web. What is semantic search? in your understanding, well let me guess in which some will say it is a just normal search whereby you may just type what you want to search and you will find it but some will find what they want which might take hours in order to be satisfied. In semantic search engine attempts were made to make sense of search results based on context. It automatically identifies the concepts structuring the texts. For instance, if you search for “election” a semantic search engine might retrieve documents containing the words “vote”, “campaigning” and “ballot”, even if the word “election” is not found in the source document.

Powerset

You can test it on Wikipedia and Powerset definitely excels at this, structuring the information and presenting it in a way that, for research purposes, is a great improvement on Wikipedia’s own search engine.

DeepDyve
