The ubiquitous keyword mode of Internet search technique is about to be taken over by a new breed of semantic search technology, according to analysts at research firm Ovum.
While keyword search remains the most popular method, it is usually not accurate, with users sometimes getting up to 30,000 hits on a search and then having to sift through a list of loosely related keyword results to find relevant documents.
"This where a new breed of so-called semantic technologies comes into the frame. Unlike ranking algorithms such as Google's PageRank for predicting relevancy, semantic search dips into the meaning in language to produce highly relevant search results," according to a report published by Ovum analysts Mike Davis and Madan Sheina.
Notable semantic web providers singled out by the analysts include Expert System, Powerset, Yedda, Trovix and Hakia. According to the authors, awareness of semantic search rose when Microsoft picked up two semantic search companies Powerset and Zoomix.
In the case of Expert System, its application, called Cogito, is designed around the principles of human comprehension to allow content to be understood in the way in which the author intended it to be. This is something that keyword search ignores.
