ALIAS 0.1

ALIAS should be considered pre-alpha softeware at present. It's an indicator of the direction we're heading in. Some things work nicely. Others occasionally break, for example, the SAT solver doesn't necessarily find all solutions.

About

ALIAS is a Python library for creating and manipulating Abstract Argumentation Frameworks (AAF). ALIAS 0.1 supports reading in and out from a variety of formats including databases and supports the evaluation of Argumentation Frameworks using Dung's [1] Abstract Argumentation Semantics.

Installation

Grab the source from githhub and install from the resulting tree:

$ git clone https://github.com/alias-org/alias.git
$ cd /alias
$ python setup.py install

Dependencies

There are no mandatory dependencies for ALIAS, however for additional functionality some are required. These additional dependencies are listed below:

• Input/Output[inout]
  1. pyparsing - For file input and output.
  2. networkx - For conversion to and from NetworkX graphs and for output using matplotlib.
• Databases[db]
  1. sqlalchemy - For interaction with SQL based database input and output.
  2. py2neo - For interaction with neo4j graph databases.
• Testing
  1. nose - Nose testing suite.

Testing

Unit testing requires nose (run from the alias package root): $ nosetests alias

Example

To create a blank AAF:

import alias
framework = alias.ArgumentationFramework('Example')

Add some arguments: framework.add_argument(['a','b'])

And an attack: framework.add_attack(('a','b'))
