relative_deltah_fl

corpustools.funcload.functional_load.relative_deltah_fl(corpus_context, segment, environment_filter=None, prevent_normalization=False, stop_check=None, call_back=None)[source]

Calculate the average functional load of the contrasts between a segment and all other segments, as the decrease in corpus entropy caused by a merger.

Parameters:

corpus_context : CorpusContext

Context manager for a corpus

segment : str

The target segment.

stop_check : callable, optional

Optional function to check whether to gracefully terminate early

call_back : callable, optional

Optional function to supply progress information during the function

Returns:

float

The difference between a) the entropy of the choice among non-homophonous words in the corpus before a merger of s1 and s2 and b) the entropy of that choice after the merger.
