This is really cool, and props to Google for making it publicly available.<p>The blog post says this can be used as a building block for natural language understanding applications. Does anyone have examples of how that might work? Parse trees are cool to look at, but what can I do with them?<p>For instance, let&#x27;s say I&#x27;m interested in doing text classification. I can imagine that the parse tree would convey more semantic information than just a bag of words. Should I be turning the edges and vertices of the tree into a feature vectors somehow? I can think of a few half-baked ideas off the top of my head, but I&#x27;m sure other people have already spent a lot of time thinking about this, and I&#x27;m wondering if there are any &quot;best practices&quot;.
