Analysing meaning of sentences

Question

Are there any tools that analyze the meaning of given sentences? Recommendations are greatly appreciated.

Thanks in advance!

Answer 1

Some natural language understanding tools can analyze the meaning of sentences, including NLTK and Attempto Controlled English. There are several implementations of discourse representation structures and semantic parsers with a similar purpose.

There are also several parsers that can be used to generate a meaning representation from the text that is being parsed.

Answer 2

I am also looking for similar tools. One thing I found recently was this sentiment analysis tool built by researchers at Stanford.

It provides a model of analyzing the sentiment of a given sentence. It's interesting and even this seemingly simple idea is quite involved to model in an accurate way. It utilizes machine learning to develop higher accuracy as well. There is a live demo where you can input sentences to analyze.

I also saw this RelEx semantic dependency relationship extractor.
