org.neo4j.nlp.helpers.GraphManager
The GraphManager class is a management wrapper around a cache of patterns that are extracted from input data, whether it be text or any other combination of symbols. Patterns are represented as a RegEx string that expands hierarchy from a genetic algorithm. Each pattern tracks the number of times it has been bound to a piece of text. The number of times eventually exceeds the current threshold and when that occurs then a new pattern is created that inherits the base pattern but extends it to account for the probability of a new part of text being present adjacent to the parent pattern. A cost function is applied as child nodes are created, which makes it more costly to reproduce. This cost function reduces the time complexity of the learning model over time.
