Abstract

A method and apparatus for locating a desired record amongst a plurality of records in a telephone directory involves associating a frequency field with each of the records, the frequency field being operable to store a frequency metric. A characteristic field is also associated with each of the records, the characteristic field being operable to store a characteristic representation of at least one identifying characteristic of a rendering associated with the record. An input representation of a rendering purporting to identify the desired record is produced and the input representation is compared with the contents of the characteristic fields of at least some of the records and confidence metrics are assigned to the records respectively, each of the confidence metrics representing a respective probability that a respective record is the desired record. A determination is then made as to which of the records have the first and second highest confidence metrics. The frequency fields of the records having the first and second highest confidence metrics are then read and the record with the highest frequency metric is identified as the desired record. Instruction codes stored on a computer-readable memory medium may be used to configure a general purpose computer to effect the method.
