Abstract: Systems and methods are provided for generating a set of classifiers. A term is identified within a document and a pre-defined threshold distance is determined. A plurality of additional terms in the document are identified, the additional terms being located within the pre-defined threshold distance of the time. A distance between the term and an additional term of the plurality of additional terms is calculated. A corresponding weight for the calculated distance is determined using a proximity weighting scheme. A score for the additional term is calculated using the calculated distance and the corresponding weight. A colocation matrix is generated and a classifier determined using the colocation matrix.

Abstract: Systems and methods are provided for generating a set of classifiers. A location is determined for each instance of a topic term in a collection of documents. One or more topic term phrases are identified, and one or more sentiment terms within each topic term phrase. Candidate classifiers are identified by parsing words in the one or more topic term phrases, and a colocation matrix is generated. A seed row of the colocation associated with a particular attribute is identified, and distance metrics are determined by comparing each row of the colocation matrix to the seed row. A set of classifiers are generated for the particular attribute, where classifiers in the set of classifiers are selected using the distance metrics.
