StarSpire: Multi-Model Semantic Interaction for Text Analytics

Semantic interaction offers an intuitive communication mechanism between human users and complex statistical models. By shielding the users from manipulating model parameters, they focus instead on directly manipulating the spatialization, thus remaining in their cognitive zone. We present the concept of multi-model semantic interaction, where semantic interactions can be used to steer multiple models at multiple levels of data scale, enabling users to tackle big data problems. We also present an updated visualization pipeline model for generalized multi-model semantic interaction.
