Development of the Interactive Term Co-occurrence Graph Visualization Component for the IFORA Information System

The goal of this work is to create experimental (yet practical) web-application, which benefits from using GPU in two different ways. From the point of view of using GPU for general purpose calculation, it is discussed, that not all algorithms can be ported from other advanced GPU APIs (like CUDA) to limited WebGL API. For the first time it is proven and the implementation is outlined for optimized (by using techniques like Barnes-Hut simulation) implementation of t-SNE on WebGL shaders. The benchmarks for non-optimized implementation of t-SNE on C compared to non-optimized GPU implementation showed the performance gain by more, than 10 times. In the second part, high development costs for interactive visualizations and high-quality video visualizations are discussed. The format for serialization of interactive visualizations and high-quality video is proposed. It allows a single web-application to act both as player for interactive visualizations and as render-farm for video creation. Four types of post-processing are implemented, usually included into applications like Adobe After Effects.
