Abstract
A system and method for attribute extraction from product titles is presented. A set of product titles are read by an embodiment. The product titles are separated into a sequence of tokens, the tokens being determined by the presence of a separator character. The sequences of tokens are labeled according to a specific encoding scheme to denote attributes of a title, such as brand name and other features. The characteristics of the attributes within the title are determined to build a sequence labeling algorithm. The results of the encoding is compared to a normalization dictionary comparing standardized attributes. A blacklist can be consulted to further refine the method. A further validation can be performed to catch any remaining mistakes. Thereafter, a database entry can be made to associate the attribute with the item. A training set can be used to initialize the learning model. Other embodiments are also disclosed herein.
