Gismo: Put a tiger in your engine

In this article, we present Gismo, a new navigation engine in document sets. Gismo combines three approaches: a symmetrical bipartite graph representation connecting documents and words that these documents contain; a measure of importance relevance of documents and words in relation to a request; a representation of the results in the form of a non-binary tree. We illustrate the interest of Gismo through a concrete example on a set of Wikipedia pages.
