Method Detail

detect

public <T extends IToken> java.util.List<IMWE<T>> detect(java.util.List<T> sentence)

Description copied from interface: IMWEDetector

Given a list of tokens, the detector searches for the MWEs in the list. It returns a set of IMWE objects representing these multi-word expressions. The method returns an empty list if no MWEs are found; the method should never return null.

Specified by:

detect in interface IMWEDetector

Type Parameters:

T - the type of the tokens in the sentence

Parameters:

sentence - a sentence which the detector should search for multi-word expressions.

Returns:

a list of IMWE objects representing the multi-word expressions found in the sentence. Returns an empty list if no multi-word expressions are found; never returns null

getStopWordIndex

protected static IMWEIndex getStopWordIndex()

Creates, opens, and returns a new stop word index.

Returns:

a new, open stop word index.
