Programmatically detect the name, location and start time of a social event on any html page [closed]

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 11 years ago.

I would love to see an app/browser extension that automatically detects meatspace events on a page by looking for words like location, date, time, etc... and then offers to add these to a calendar

If there is a large enough sample of these occurrences is there anyway to train an app to开发者_如何学运维 detect it? Are there any machine learning technique that could help with this?

It is better to write grammar for detection things like date/time/location. You can check example here http://code.google.com/p/graph-expression/
