Description: Animation of the topic detection process in a document-word matrix. Every column corresponds to a document, every row to a word. A cell stores the frequency of a word in a document, dark cells indicate high word frequencies. Topic models group both documents, which use similar words, as well as words which occur in a similar set of documents. The resulting patterns are called "Topics".
