skg-connector 0.1.16

Module to extract and store data into an SKG

System Knowledge Graphs (SKGs) to Automata

Description

Module developed within the Auto-Twin Horizon EU project to extract data from Neo4j SKGs for automata learning purposes and to store learned automata into the SKG.

Requirements

Follow instructions for the promg-core project to create the SKG.

Configuration

The default configuration file is available in the ./resources/config/ folder.

The module currently assumes the Neo4j instance to be running on localhost:7687: if this is not the case, update the config.ini file accordingly.

How to use

Available queries are implemented as methods of the Skg_Reader class:

• get_events(): Returns all Event nodes.
• get_events_by_date(start_t, end_t): Return Event nodes filtered by timestamp. If both start_t and end_t are given, it returns events such that the timestamp is within range [start_t, end_t]. If only one parameter is specified, it returns events such that the timestamp is greater than start_t or smaller than end_t. If no parameter is specified, it returns all events.
• get_entities(): Returns all Entity nodes.
• get_sensors(): Returns all Class nodes.
