..."Traditional search engines are unable to sustain the pace of information growth primarily because they lack the intelligence to “understand,” semantically process, mine, infer, connect, and contextually interpret information to transform it to — and expose it as — knowledge."..."The Semantic Web addresses the need to understand and contextually interpret information, by marking up documents and providing metadata for the Web. Technologies such as RDF and OWL provide common structures that support exchange of data using XML. In contrast to the Semantic Web, however, there are search technologies that do not require any metadata to understand the documents and therefore require no markup of legacy information."...."The Problem with Keywords...Today’s search engines cannot discern between keywords when those keywords are used in different contexts. For instance, the word “bank” can mean very different things — a commercial bank, riverbank, or “the sudden bank of an airplane.” This shortfall obliges users to manually filter out thousands of irrelevant results that have the right keywords but in the wrong context (false positives).An intelligent information retrieval system must be able to retrieve information that doesn’t have the user’s expressed keywords but which is semantically relevant to those keywords. This would address the false negatives problem — wherein search engines leave out results that they deem irrelevant only because the results don’t contain the “right” keywords."...."Understanding the difference between standard search retrieval and true knowledge discovery is an important step in helping knowledge workers gain insight and grapple with larger universal health and medical issues"
