ABSTRACT OF THE DISCLOSURE The present invention provides a method for resolving a common name purported to identify a database entry with the database entry names stored in the index. The pur- ported and entry names each comprise a first field, a second field, and a third field, with at least the first field including at least one word. Purported names are provided to the name resolution process in a normalized form referred to as the "Common Name" format. Entry names are stored in a similar normalized form. The name resolution process begins by determining an exact match score and initializing count fields. The process then constructs a set of all index entries having first (surname) fields matching the first (surname) field of the purported word. The process then selects an initial "guess" at the surname component of the purported name and identifies all index entries having either (a) surnames equal to the last word of the purported name "surname" field or (b) multiple word surnames whose last word equals the last word of the purported name "surname" field. Then, for each of the entry names in the set, the process compares the first fields of the entry name and purported name and, if the first fields of the purported and entry names do not match, selects another entry name from the set. The process then selects a second field from the purported name and compares the second fields of the purported and entry names. In this comparison, the order of words in the second fields is immaterial, that is, only the number of matching words in the fields is considered. The process selects a third (personal name) field from the purported name and performs the following sequence of steps for each word in the third field of the purported name. The process compares the selected word of the purported name with the word in the same position in the third field of the entry name. If the words match, the process selects the next word in the third (personal name) field of the purported name and returns to the start of this se- quence. If the words do not match, but a word exists in the third field of the entry name that is comparable to the word selected from the third field of the purported name, the process compares the initial characters of the words in the third fields of the purported and entry names. An alternate or additional embodiment of the process of the present invention also provides for an additional comparison for alternate or alias names in the third (personal name) field. The final step of the process then determines a comparison score for the degree of similarity between the purported and entry names and selects the best match.
