% Configuration file for an Atomspace-based dictionary. It will use
% any available data in the AtomSpace to perform parsing. Disjunct
% data is preferred, if it is available; else word-pair data is used.
% if even that is not available, random planar parsing will be done.
%
% All config values can be left as-is; nothing here needs tweaking.
%
% No StorageNode is used; the config here assumes that we will be
% working within an AtomSpace where everything needed has already
% been loaded. The Link Parser works great with dynamically loaded
% atoms; i.e. it will pull them from Storage if Storage is given.
% What is missing/cinomplete is on-the-fly computation of MI.
%
% See the `demo-atomese/storage.dict` file in the main Link Grammar
% distribution for detailed documentation.

%

% Keep in mind that the parser ranks parses from lowest to highest cost.
% If word-pair links have a negative cost, the parser is incentivized to
% add as many of these as possible, while still resulting in a planar
% graph with many loops. Viz, "Maximal Planar Graphs" (MPG). Conversely,
% if word-pair links have a positive cost, Minimal Spanning Trees (MST)
% will be created (minimizing the total cost.)
% Default cost for `ANY` link types. The `ANY` link type is meant to
% provide a desperate, last-chance opportunity to link to a word that
% does not appear in any disjuncts or word-pairs. Thus, its given some
% high cost, so that it is not used when other links are available.
