Automatically classifying product description information includes selecting a first word from the information and determining whether the word is defined as a prefix within one or more keywords, each keyword being associated with one of a plurality of classes, each class being associated with one or more keywords. If the word is defined as a prefix, then for each keyword for which the word is defined as a prefix, determine whether all suffixes of the prefix within the keyword are found among all remaining words in the information in sequence. For each keyword for which this is true, generate a new result for each class associated with the keyword. Then select a first new result; compare the new result with one or more previous results each corresponding to a class; if a suffix count for the new result is greater than a suffix count for a previous result, mark the new result as unambiguous, the new result being thereafter considered a previous result; and if one or more new results generated for the first word remain unselected, select a next new result and repeat until no new results remain unselected. If one or more words in the information remain unselected after processing the first word, select a next word and repeat until no words remain unselected. If a single previous result is marked as unambiguous after all words in the information have been selected and processed, then classify the information in the class corresponding to the previous result marked as unambiguous.
