A Drools is a rule engine which uses a rule-based approach to implement an Expert system. Python is one option as well but in this case I wouldn’t go that way. Data is represented in the form of graphs, and more generally, as hypergraphs; thus the AtomSpace is a kind of graph database, the query engine is a general graph re-writing system, and the rule-engine is a generalized rule-driven inferencing system. In this article, we will be looking on how the Apriori algorithm works with a python example. 'regex' module 3. More control flow tools in Python 3.
