Projection module

Projection module performs dimensionality reduction of the high-dimensional document vector space into a 2D visualization space. In the resulting 2D space spatial distance is a measure for relatedness: related documents are placed close to each other while dissimilar ones are positioned far apart.

The resulting layouts are useful for visual exploration and analysis purposes. Available projection methods are both scalable and incremental, thus supporting explorative visualization of large, dynamically changing data sets.
