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.

Abstract: A system and computer-implemented method for predicting a search term of a search are disclosed. The method includes building, by a server, a search prediction dictionary database, the search prediction dictionary database including a plurality of search terms and a plurality of prediction scores corresponding to the plurality of search terms; receiving, by the server, one or more characters from a user device over a network, the one or more characters corresponding to the search; identifying, by the server, one or more predicted search terms based on the one or more characters, the identifying including determining one or more of the plurality of search terms including the one or more characters; and providing, by the server, a search term prediction list including the one or more predicted search terms to the user device for display on a display device of the user device.
