  • Patent number: 11308098
    Abstract: A system and method for translating and matching attributes in data records that describe travel items is provided. In an embodiment, a plurality of records is received from a plurality of data sources. Record parsing logic is used divide strings in the records into individual words and match single words in the plurality of records to attributes. Using the matched attributes, record comparison logic creates a confidence score that describes the likelihood that two records describe the same listing or inventory item. If the confidence score exceeds a given threshold, the records are determined to match. A consolidated record is then created from the two matched records.
