Abstract
A computer-implemented method for correcting a spelling of a search term includes extracting search information from a clickstream database that includes search keywords received by a search engine. A server builds a database of acceptable terms that includes search keywords from the clickstream database that match a product in a product database. The server builds a database of correctable terms that include search keywords from the clickstream database that do not match a product in the product database. A plurality of spell correction candidates are identified based on the search keywords in the database of correctable terms. A confidence value for each of the plurality of spell correction candidates is determined. The spell correction candidate having a relatively highest confidence value among the confidence values for the plurality of spell correction candidates is stored in the database of correctable terms.
