For chained Algorithms with action train, tag or evaluate you need to specified parameters in a configuration file. Two default configuration files are defined in ./bilbo/config/ directory. The order of data processing must be clarified. For each pipe you need to fullfilled the algorithm specification.
For specify order and used algorithms see pipeline options
Each pipe is launching a component. At each passage, document object is enhanced from differents attribute. Attribute can be extract (extractor component class) or predict (estimator component class)
