ABSTRACT
We present Luminoso, a tool that helps researchers to visualize and understand a dimensionality-reduced semantic space based on textual information by exploring it interactively. It streamlines the process of creating such a space by taking input from a directory of text documents, and optionally including common-sense background information. This interface is useful for interactively discovering trends in a text corpus, such as free-text responses to a survey. We discuss a case study about restaurant reviews to show how Luminoso can be used for opinion mining.
