Field Detail

map

public final Map<String,Object> map

The attribute map populated by this builder.

Constructor Detail

STCClusteringAlgorithmDescriptor.AttributeBuilder

protected STCClusteringAlgorithmDescriptor.AttributeBuilder(Map<String,Object> map)

Creates a builder backed by the provided map.

Method Detail

query

public STCClusteringAlgorithmDescriptor.AttributeBuilder query(String value)

Query that produced the documents. The query will help the algorithm to create better clusters. Therefore, providing the query is optional but desirable.

See Also:

STCClusteringAlgorithm.query

documents

public STCClusteringAlgorithmDescriptor.AttributeBuilder documents(List<Document> value)

Documents to cluster.

See Also:

STCClusteringAlgorithm.documents

clusters

public List<Cluster> clusters()

Clusters created by the algorithm.

See Also:

STCClusteringAlgorithm.clusters

ignoreWordIfInFewerDocs

public STCClusteringAlgorithmDescriptor.AttributeBuilder ignoreWordIfInFewerDocs(int value)

Minimum word-document recurrences.

See Also:

STCClusteringAlgorithm.ignoreWordIfInFewerDocs

ignoreWordIfInHigherDocsPercent

public STCClusteringAlgorithmDescriptor.AttributeBuilder ignoreWordIfInHigherDocsPercent(double value)

Maximum word-document ratio. A number between 0 and 1, if a word exists in more snippets than this ratio, it is ignored.

See Also:

STCClusteringAlgorithm.ignoreWordIfInHigherDocsPercent

minBaseClusterScore

public STCClusteringAlgorithmDescriptor.AttributeBuilder minBaseClusterScore(double value)

Minimum base cluster score.

See Also:

STCClusteringAlgorithm.minBaseClusterScore

maxBaseClusters

public STCClusteringAlgorithmDescriptor.AttributeBuilder maxBaseClusters(int value)

Maximum base clusters count. Trims the base cluster array after N-th position for the merging phase.

See Also:

STCClusteringAlgorithm.maxBaseClusters

minBaseClusterSize

public STCClusteringAlgorithmDescriptor.AttributeBuilder minBaseClusterSize(int value)

Minimum documents per base cluster.

See Also:

STCClusteringAlgorithm.minBaseClusterSize

maxClusters

public STCClusteringAlgorithmDescriptor.AttributeBuilder maxClusters(int value)

Maximum final clusters.

See Also:

STCClusteringAlgorithm.maxClusters

mergeThreshold

public STCClusteringAlgorithmDescriptor.AttributeBuilder mergeThreshold(double value)

Base cluster merge threshold.

See Also:
