Class VectorMapSemanticSpace<T extends Vector>

java.lang.Object

edu.ucla.sspace.common.VectorMapSemanticSpace<T>

All Implemented Interfaces:

SemanticSpace, Serializable

public class VectorMapSemanticSpace<T extends Vector>
extends Object
implements SemanticSpace, Serializable

This SemanticSpace wraps a Map from strings to Vectors. Both processDocument(java.io.BufferedReader) and processSpace(java.util.Properties) are no-ops.

Constructor Detail

VectorMapSemanticSpace

public VectorMapSemanticSpace(Map<String,T> wordSpace,
                      String spaceName,
                      int dimensions)

Creates a new VectorMapSemanticSpace around the pre-existing Map.

Method Detail

getWords

public Set<String> getWords()

Returns the set of words that are represented in this semantic space.

Specified by:

getWords in interface SemanticSpace

Returns:

the set of words that are represented in this semantic space.

getVector

public T getVector(String term)

Returns the semantic vector for the provided word.

Specified by:

getVector in interface SemanticSpace

Parameters:

term - a word that may be in the semantic space

Returns:

The Vector for the provided word or null if the word was not in the space.

getSpaceName

public String getSpaceName()

Returns a unique string describing the name and configuration of this algorithm. Any configurable parameters that would affect the resulting semantic space should be expressed as a part of this name.

Specified by:

getSpaceName in interface SemanticSpace

getVectorLength

public int getVectorLength()

Returns the length of vectors in this semantic space. Implementations are left free to define whether the returned value is valid before processSpace is called.

Specified by:

getVectorLength in interface SemanticSpace

processDocument

public void processDocument(BufferedReader document)

A no-op

Specified by:

processDocument in interface SemanticSpace

Parameters:

document - a reader that allows access to the text of the document

processSpace

public void processSpace(Properties props)

A no-op

Specified by:

processSpace in interface SemanticSpace

Parameters:

props - a set of properties and values that may be used to configure any exposed parameters of the algorithm.
