One disadvantage of this approach is that you have to hand code lots of language knowledge. They don't seem to have solved the problem of acquiring such knowledge from training data. How much effort would it be to code enough knowledge to pass the Turing test? Nobody knows. Also, what do you do with the data after you get it into a structured format? I think the problem of converting it back to natural language output is going to be at least as hard. The structured format makes use of predicates that don't map neatly to natural language. The paper is not dated, but there are no references after 1991. I wonder why there has been no real progress using this approach in the last 16 years. However, the paper has lots of nice examples showing how natural language is hard to process. -- Matt Mahoney, [EMAIL PROTECTED] ----- This list is sponsored by AGIRI: http://www.agiri.org/email To unsubscribe or change your options, please go to: http://v2.listbox.com/member/?list_id=303
