public interface EvidenceTable
extends GenericTable

An interface for accessing a HTable that will store syntactic patterns between noun pairs. Many of these functions are to allow for a different underlying structure of the table. Each table schema can have it's own column family names, column names, and internal structure for each feature type. Schemas must permit at least the following behaviours:

• Dependency path counts can be stored based on their source corpus
• Dependency path counts can be accessed based on their source coprus
• Hypernym class labels and cousin class labels must be storable and accessible
• The table must be createable

Method Detail

nounPair

StringPair nounPair(org.apache.hadoop.hbase.client.Result row)

Returns a StringPair for the noun pair held in the given Result.

getDependencyPaths

Counter<String> getDependencyPaths(org.apache.hadoop.hbase.client.Result row)

Returns a new map that contains all of the dependency path counts, regardless of their source.

getDependencyPaths

Counter<String> getDependencyPaths(org.apache.hadoop.hbase.client.Result row,
                                   String source)

Returns a map that contains all of the dependency paths associated with a single noun pair.

putDependencyPaths

void putDependencyPaths(String word1,
                        String word2,
