Ontology-Mediated Planning

This repository contains a tool for planning w.r.t. to OWL ontologies. The implementation is based on the approach discussed our paper "Planning with OWL-DL Ontologies" (presented at ECAI 2024).

Usage

Docker

The easiest way to use our tool is to download the docker iamge provided on Zenodo.

  1. obtain the container image omplan.tar using this download link
  2. load image docker load -i omplan.tar
  3. use docker run omplan to solve ontology-mediate planning problems
    • run examples from repository: 
      docker run omplan <directory-of-files> <name-of-ontology-file> <name-of-PDDL-domain-file> <name-of-PDDL-problem-file>
    • run using your own files by mounting the directory from your machine: 
      docker run -v <directory-on-your-machine>:<directory-in-container> omplan <directory-of-files> <name-of-ontology-file> <name-of-PDDL-domain-file> <name-of-PDDL-problem-file>
    • the tool expects a fluents.txt and a hooks.txt file in the folder that specify the interface between the planning domain / problem and the ontology. To see an example how to specify the interfacr, you should have a look at the blocksworld domain.
    • the plan (if found) is output on the terminal and saved in the specified folder

Options

  • automatically, a folder misc is created, to save the intermediate PDDL files and log files. If you wish to automatically delete them, you can append -delete-misc to the arguments
  • if you want to provide a time limit, you can add the number of seconds
  • overall, this might look like this (60s time limit for planning and misc folder gets deleted): 
    docker run omplan examples/performance_check/pipesA-8 pipesA-8.ttl pipes.pddl pipesProblemA-8.pddl 60 -delete-misc

Usage without Docker

  1. see file Installation.md for instructions how to set up the tool correctly

  2. run the tool by calling:

    ./omPlanner.sh <directory-of-files> <name-of-ontology-file> <name-of-PDDL-domain-file> <name-of-PDDL-problem-file>

e.g.

./omPlanner.sh examples/performance_check/pipesA-8 pipesA-8.ttl pipes.pddl pipesProblemA-8.pddl
  • the generated plan will be saved to the specified folder
  • the tool builds the necessary .jar file if it does not exist yet, if you change the source code you have to manually run sbt assembly to generate a new .jar
  • the options are the same as for running the tool with docker

Evaluation ECAI 2024 paper
