Versus is a framework which decomposes digital content based comparisons into reusable components of adapters which load data, extractors which extract semantically meaningful features within the data, descriptors which represent the data contents, measures which compare two descriptors to obtain a numerical difference, and indexers which organize a set of content descriptors according to some measure for efficient retrieval. Versus addresses a need to compare digital content amongst unstructured data (e.g. raw sensor data) and search collections for similar data.
