Query: Newer method of string comparison: the Modified Moving Contracting
  Window Pattern Algorithm   This paper presents a new algorithm, the Modified Moving Contracting Window
Pattern Algorithm (CMCWPM), for the calculation of field similarity. It
strongly relies on previous work by Yang et al. (2001), correcting previous
work in which characters marked as inaccessible for further pattern matching
were not treated as boundaries between subfields, occasionally leading to
higher than expected scores of field similarity. A reference Python
implementation is provided.
