Need computer science maven! Predicate languages...

December 10, 2014 5:25 PM

I was peripherally involved in a recent work project predicate languages parsing and some natural language. I am interested in learning about modern development environments in these areas. Very basic and on up - I know what predicates are and natural language processing at a beginner level, decent understanding of code and networks, but not computer scientist. I want to easily parse and database a string of predicates from another application, set a value, quickly evaluate only if relevant, evaluate them against a database and set a shared memory location. All thoughts appreciated!

I don't completely understand the question, and I'm not a computer scientist, but this is Metafilter so:

You might want to check out NLTK (Natural Language Toolkit), which is a Python library with a variety of tools for linguistic analysis.

Seconding NLTK; it's pretty much the go-to package for this sort of thing.

Response by poster: Quite simple app at its core.

Receive and store a string of user entered logical expressions against keys of an in memory structure. eg dbfield>0 These user entered expressions can be completely dynamic and real-time

Process organizes expressions by key and evaluates them setting a bit in shared memory or raise event callback if true.

The natural language bit is sort of cool, but not sure required. Even a simple UI to browse metadata and available expressions/operations would work.

You're not doing a great job of explaining here. Maybe if you clarify exactly what you mean, in complete sentences, you'll get better answers.
