  COALS first computes a term by term co-occurrance using a ramped 4-word window. Once all documents have been processed, the co-occurrence matrix will be re ordered such that only the {@code N} most frequent terms have theirsemantic vectors retained and only the {@code M} most frequent terms are usedas co-occurrence features. These values can be set by the {@value #MAX_WORDS_PROPERTY} and {@value MAX_DIMENSIONS_PROPERTY} properties,resepctively. After re ordering the semantic vectors and features, {@link CorrelationTransform} is used to rerank all co-occurrence scores. As part ofthis transform, all negative correlations are dropped and replaced with a 0. Finally, and optionally, the {@link SVD} is used to reduce the semanticspace. To set the number of retained dimensions via {@link SVD}, set the {@value REDUCE_DIMENSION_PROPERTY} property. @author Keith Stevens
