get_glueformulas_from_semtype_entry(lookup, word, node, depgraph, counter)[source]
get_label(node)[source]

Pick an alphabetic character as identifier for an entity in the model.

Parameters

value (int) – where to index into the list of characters

get_meaning_formula(generic, word)[source]
Parameters

  • generic – A meaning formula string containing the parameter “<word>”

  • word – The actual word to be replace “<word>”

get_semtypes(node)[source]

Based on the node, return a list of plausible semtypes in order of plausibility.

initialize_labels(expr, node, depgraph, unique_index)[source]
lookup(node, depgraph, counter)[source]
lookup_unique(rel, node, depgraph)[source]

Lookup ‘key’. There should be exactly one item in the associated relation.
