Document Comparison

  • LKE implements a very general and powerful approach to document comparison
    • The documents being compared (may be more than 2) need not have the same (or even similar) structure
    • You define the set of data elements to be used for comparison; these may be of different types for different documents
    • Element A (may be a sentence only to be found in page 1) in document 1 may be compared with Element B (may be a phrase only to be found in a table) in document 2
    • The comparison criteria may be defined as a (boolean) combination of various conditions with support for custom comparison functions, textual entailment and keyphrase matching
    • Apart from string comparison (using algorithms such as Cosine similarity), comparison of numeric values and dates is supported
