The example embodiments are directed to a system and method for tag mapping. In one example, the method includes receiving a request to perform tag mapping for a target tag of a master data set, the target tag representing a target component of an asset, querying a customer data for a plurality of candidate tag records based on the target tag, tokenizing the plurality of candidate tag records included in the customer data set, reducing an amount of the tokenized tag records in the customer data set based on the target tag and each tokenized candidate tag record, performing tag mapping with the reduced amount of tokenized tag records to identify at least one candidate tag that is a possible match to the target tag, and outputting information concerning the identified at least one matching candidate tag.
