19. The method of claim 1 , wherein determining comparable attribute value probabilities to determine attribute value probabilities that are representative of the comparable attribute value probabilities further comprises at least one of: averaging the comparable attribute value probabilities; discarding outliers of the comparable attribute value probabilities and averaging remaining ones of the comparable attribute value probabilities; and selecting a median of the comparable attribute value probabilities.
1. A method of establishing a profile of an entity based on a plurality of products associated with the entity, the method comprising: for each of the plurality of products: for each of a plurality of attributes associated with each of the plurality of products: determining, using a first analyzer implemented by at least one computer and based on at least one product description of the product, an attribute probability set for the attribute according to a probability that each of a plurality of attribute values corresponding to the attribute is representative of the product based on the product description, thereby providing a plurality of attribute value probability sets, the plurality of attribute value probability sets corresponding to the plurality of attributes associated with each product of the plurality of products; determining, by a second analyzer implemented by the at least one computer and operatively connected to the first analyzer, those attribute value probabilities across the plurality of attribute value probability sets that are comparable to each other to provide a plurality of comparable attribute value probabilities; determining, by the second analyzer, attribute value probabilities that are representative of each of the plurality of comparable attribute value probabilities to provide representative attribute value probability sets; and providing, by the second analyzer, the profile of the entity based on the representative attribute value probability sets.
