Lattices

Reference

This software was used in Beniamine (2021).

By default, this will start by computing patterns. To work with pre-computed patterns, pass the path to the pattern computation metadata with patterns=<path/to/metadata.json>.

Lattice options are under the lattice namespace. Available lattice options (see also the common options):

class qumin.config.config.LatticeConfig(*, shorten=False, aoc=False, export=<factory>, display=<factory>)[source]

Configuration for the ``lattice`` action.

Parameters:

  • shorten (bool) – Drop redundant columns altogether. Useful for big contexts, but loses information. The lattice shape and stats will be the same. Avoid using with –html

  • aoc (bool) – Only attribute and object concepts. Sometimes faster for large lattices.

  • export (LatticeExportConfig) – Options for lattice export.

  • display (LatticeDisplayConfig) – Options for lattice drawing.

Values for the layout keyword:

class qumin.config.config.LatticeDisplayConfig(*, horizontal=False, topdown=True, layout='qumin')[source]

Export configuration for the ``lattice`` action.

Parameters:

  • horizontal (bool) – direction of the lattice (top->down or left->right).

  • topdown (bool) – Whether to start drawing from top to down or vice-versa.

  • layout (str) – Drawing layout. Supported values are “qumin” for Qumin’s internal algorithm, or the following networkx layouts: ‘dot’ (requires pygraphviz), ‘radial’ (requires pygraphviz), ‘spring’, ‘kamada_kawai’.

Values for the export keyword:

class qumin.config.config.LatticeExportConfig(*, html=True, ctxt=False, stat=False, pdf=True, png=False)[source]

Export configuration for the ``lattice`` action.

Parameters:

  • html (bool) – Export to html

  • ctxt (bool) – Export as a context

  • stat (bool) – Output stats about the lattice

  • pdf (bool) – Export as pdf

  • png (bool) – Export as png

The default configuration for these keys looks like this:

lattice:
  shorten: false
  aoc: false
  export:
    html: true
    ctxt: false
    stat: false
    pdf: true
    png: false
  display:
    horizontal: false
    topdown: true
    layout: qumin
