Is there a good natural language processing librar

问题:

I need to implement some NLP in my current module. I am looking for some good library that can help me here. I came across \'LingPipe\' but could not completely follow on how to use it.
Basically, we need to implement a feature where the application can decipher customer instructions (delivery instructions) typed in plain english. Eg:

• Will pick up at 12:00 noon tomorrow
• Request delivery after 10th June
• Please do not send before Wednesday
• Add 10 more units of XYZ to the order

回答1:

LingPipe is very nice and well documented. You can also take a look at:

• OpenNLP
• Stanford NLP
• Apache UIMA
• GATE
• CogComp-NLP
• FrameNet

The last one specifically might be of interest to you, although I don\'t know whether there are any readily available Java implementations (and maybe that\'s too big of a gun for your problem anyway :-)

Paul\'s idea of using a DSL is probably easier and faster to implement, and more reliable to use for your customers. I, too, would recommend looking into that first.

I think whether or not you choose to use NLP might depend on the specific requirements for your system. Is it a requirement that free-form english should be accepted, or will only a certain set of instructions be accepted? It might be easier to build a domain specific language that supports what your users need to convey than to do full-on semantic analysis of free-form text.

In the Java space, Groovy has some support for building DSLs.
