Constructor Detail

Continuous

public Continuous(IMWEDetector d)

Constructs the detector from the given backing detector.

Parameters:

d - the IMWEDetector that will be used to back this detector. May not be null.

Throws:

java.lang.NullPointerException - if the backing detector is null

Since:

jMWE 1.0.0

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

Overrides:

detect in class HasMWEDetector

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

isDiscontinuous

public static <T extends IToken> boolean isDiscontinuous(IMWE<T> mwe,
                                                         java.util.List<T> sentence)

Determines if the specified MWE is continuous, i.e., there are no interstitial tokens inside its boundaries that are not a part of the MWE.

Type Parameters:

T - the token type of the MWE

Parameters:

mwe - the MWE in question, may not be null

sentence - the sentence from which the MWE is drawn

Returns:

true if the MWE is continuous; false otherwise.

Throws:

java.lang.NullPointerException - if the specified mwe is null, or does not come from the specified sentence

Since:

jMWE 1.0.0

isDiscontinuous

public static <T extends IToken> boolean isDiscontinuous(IMWE<T> mwe,
                                                         java.util.Map<T,java.lang.Integer> indexMap)

Determines if the specified MWE is continuous, i.e., there are no interstitial tokens inside its boundaries that are not a part of the MWE.

Type Parameters:

T - the token type of the MWE

Parameters:

mwe - the MWE in question, may not be null

indexMap - a map from sentence tokens to their index in the sentence

Returns:

true if the MWE is continuous; false otherwise.

Throws:

java.lang.NullPointerException - if the specified mwe is null

Since:

jMWE 1.0.0
