public TextRankSummarizer()

Method Detail

extract

public Extraction extract(@NonNull
                          @NonNull HString hString)

Description copied from interface: Extractor

Generate an Extraction from the given HString.

Specified by:

extract in interface Extractor

Parameters:

hString - the source text from which we will generate an Extraction

Returns:

the Extraction

fit

public void fit(@NonNull
                @NonNull DocumentCollection corpus)

Description copied from interface: Summarizer

In certain cases a Summarizer needs to collect corpus level statistics or construct a model of what a good summarization looks like. The fit method allows implementations to perform this logic at a corpus level.

Specified by:

fit in interface Summarizer

Parameters:

corpus - the corpus to fit the extractor to
