Language Question

“Powerset Hype to Boiling Point”, said a February headline on TechCrunch. In the last installment of this column, I asked whether 2007 would be the year of question-answering. My query was occasioned by a number of new attempts at natural language question-answering that were being promoted in the marketplace as the next advance upon search, and particularly by the buzz around the stealth-mode natural language search company Powerset. That buzz continued with a major news item in the first quarter of this year: in February, Xerox PARC and PowerSet struck a much-anticipated deal whereby PowerSet won exclusive rights to use PARC's natural language technology, as announced in a VentureBeat posting. Following the scoop, other news sources drew the battle lines with titles like “Can natural language search bring down Google?”, “Xerox vs. Google?”, and “Powerset and Xerox PARC team up to beat Google”. An April posting on Barron's Online noted that an analyst at Global Equities Research had cited Powerset in his downgrading of Google from Buy to Neutral. And, all this on the basis of a product which, at the time of writing, very few people have actually seen. Indications are that the search engine is expected to go live by the end of the year, so we have a few more months to wait to see whether this really is a Google-killer. Meanwhile, another question remaining unanswered is what happened to the Powerset engineer who seemed less sure about the technology's capabilities: see the segment at the end of D7TV's PartyCrasher video from the Powerset launch party. For a more confident appraisal of natural language search, check out the podcast of Barney Pell, CEO of Powerset, giving a lecture at the University of California–Berkeley.

Language Question

Whatever knowledge a database contains, one of the essential questions in its design and usability is how its users will interact with it. If these users are human agents, the most ordinary way to query a database would be in the natural language (Gazdar, 1999; Popescu, Etzioni, & Kautz, 2003; Sabourin, 1994). Natural language question answering (NL Q/A), wherein questions are posed in a plain language, may be considered the most universal but not always the best (i.e., fastest) way to provide the information access to a database. One should be aware that approaches to data access, such as visualization, menus and multiple choice, FAQ lists, and so forth, have been successfully employed long before the NL Q/A systems came into play. In the following, I discuss situations in which a particular information access approach is optimal.
