NAME

NNexus::Classification - Dismabiguation logic for NNexus concept harvests

SYNOPSIS

    use NNexus::Classification qw(disambiguate msc_similarity);
    my $concepts_refined = disambiguate($concept_harvest,%options);
    my $similarity_score = msc_similarity($category1,$category2);

DESCRIPTION

NNexus::Classification contains disambiguation and clustering algorithms for determining a subset of "relevant" concept candidates from a given concept harvest. Relevance is determined heuristically. The current algorithm considers two facets of "relevance":

  1. Relevant candidates come from empirically similar domains of knowledge.
  
  To this extent, a similarity metric has been extracted from 3+ million mathematical reviews
  in Zentrallblatt Math, each annotated with categories from the Math Subject Classification.

  2. Technical terms are more likely to be relevant. Consequently:
   - The more words in a candidate, the more likely that it is a term
   - The more characters in a candidate, the more likely that it is a term

METHODS

my $concepts_refined = disambiguate($concept_harvest,%options);

  Disambiguates a concept harvest, as returned by NNexus::Discover, following the
  algorithm in the description.

  Currently the only accepted option is a boolean value for "verbosity".

my $similarity_score = msc_similarity($category1,$category2);
