Automatic Extraction of Information

Researchers have developed a software engine that pulls together facts by searching through more than 500 million Web pages. The tool automatically extracts meaning from billions of lines of text by analyzing basic word relationships. If you use this system, you have to either enter a question or an argument. For example, the question “Who built the pyramids?” will give a long list of results. Some experts say that this kind of "automated information extraction" will form the basis for far more intelligent next-generation Web searches, in which bits of information are first collected and then combined intelligently.
