+description: >-
+  METEOR, an automatic metric for machine translation evaluation
+
+  that is based on a generalized concept of unigram matching between the
+
+  machine-produced translation and human-produced reference translations.
+
+  Unigrams can be matched based on their surface forms, stemmed forms,
+
+  and meanings; furthermore, METEOR can be easily extended to include more
+
+  advanced matching strategies. Once all generalized unigram matches
+
+  between the two strings have been found, METEOR computes a score for
+
+  this matching using a combination of unigram-precision, unigram-recall, and
 
+  a measure of fragmentation that is designed to directly capture how
+
+  well-ordered the matched words in the machine translation are in relation
+
+  to the reference.
+
+
+  METEOR gets an R correlation value of 0.347 with human evaluation on the
+  Arabic
+
+  data and 0.331 on the Chinese data. This is shown to be an improvement on
+
+  using simply unigram-precision, unigram-recall and their harmonic F1
+
+  combination.
