Method Detail

getKnowledgeMatrix

DoubleSparseMatrix getKnowledgeMatrix()

A knowledge matrix saves the semantic relationships between various concepts. For example, a row may stand for a multiword phrase, e.g. space program and a column denote a signle word. Thus a cell in the matrix may be interpreted as the probability of the phrase beging translated to the single word semantically.

Returns:

the knowledge matrix

getRowKeyList

SimpleElementList getRowKeyList()

Returns:

a list of concept names corresponding to each row

getColumnKeyList

SimpleElementList getColumnKeyList()

Returns:

a list of concept names corresponding to each column
