1. Choose your clustering engine

There are many different engines available on the Internet. These are generally specific. Most process data from Web queries. However, some engines are specific to a given source, for example information from Wikipedia, with a choice of language for the source (Wiki in English, French, etc.) of press articles and agency dispatches. The presentation of results varies from one engine to another, but these representations always reflect the seriation of results. For example, results are presented in grids, pie charts, rectangles with different surfaces, etc.

These different engines are available either free of charge, or on a pay-per-use basis to access more powerful functions, or to process more results. The examples presented in this datasheet relate to the clusters available free of charge.
