TEXT-MACHINE CODE, SYSTEM AND METHOD

摘要

An automated method, system and machine readable code for comparing an input text in a selected field with each of a plurality of natural-language texts in the same field are disclosed. In the method, each of a plurality of terms characterizing the input text (32) is associated with a selectivity value (40) related to the frequency of occurrence of that term in a database (38) of digitally processed texts in the selected field (30), relative to the frequency of occurrence of the same term in a database of digitally processed texts in one or more unrelated fields. For each of the plurality of natural-language texts in the same field, a match score related to the number of terms derived from that text that match those of the input text, weighted by selectivity values of the matching terms, is determined. The highest-score matches are then determined.
