Google open-sources natural language understanding tools

These tools allow machines to read and understand English text (such as text you type into a browser to do a Google search). And the Parsey McParseface program implements SyntaxNet in English (it learned from an annotated collection of old newswire stories called The Penn Treebank Project). Here's an example of how it parses and analyzes an English sentence:Using deep neural networks, SyntaxNet is implemented in Google's TensorFlow (see Google open-sources its TensorFlow machine learning system). On a standard benchmark consisting of randomly drawn English newswire sentences ("Penn Treebank"), Parsey McParseface recovers individual dependencies between words with over 94% accuracy, Google says.
