Although online searching capabilities has grown by leaps and bounds we still manage to get frustrated when our search engines don’t understand exactly what we are searching for. “Sometimes using a search engine can be maddening. Especially when the keywords you expect to lead straight to the pages detailing what you seek turn out to be only tangentially related to that subject.” Researchers are working on developing a not so new technology, semantic technology. This will allow search engines to extract the meaning of certain queries and should be able to produce, much more readily, the intent behind search terms. “Applying this technology could mean machines achieve significant insights into the way people understand the world. It could feed a breakthrough in an area of science that has long frustrated mankind.”
