Allow easy access to takeaways for a given concept on a per paper basis

Search based on keywords. Maybe make use of an existing search engine, e.g. Woosh?

Easy navigation of this is likely to be enabled by an interactive visualization language such as D3.js.

Some good examples from the gallery:

• smooth zooming
• zoomable circle packing
• hierarchical edge bundling
• collapsible tree
• tangled tree
• force-directed tree
• disjoint force-directed graph
• voronoi labels

A more generally useful and related feature:
an (n_paper, n_concepts) array that shows the inner product between each paper and each concept (i.e. the projection of the paper into concept space).
This will save significant computational time for calculating inner products if done correctly.
