 ===== Measures for sentences =====  ===== Measures for sentences =====

 +Two measures (maxNPLength and maxNPDepth) concern noun phrases, defined as subtrees headed by words whose upos is NOUN, PNOM or PRON.
 +
 +Except for the mdd measure, punctuation and coordination is excluded. 
  
   * maxNPLength: number of words in the longest noun phrase   * maxNPLength: number of words in the longest noun phrase
   * maxNPDepth: number of embeddings in the noun phrase with the longest chain of embeddings    * maxNPDepth: number of embeddings in the noun phrase with the longest chain of embeddings 
   * sLength: sentence length = no. of words in the sentence (punctuation excluded)   * sLength: sentence length = no. of words in the sentence (punctuation excluded)
-  * subRatio: subordination ratio = (no. of T-units + no. of clauses) / no. of T-units((T-unit is a main clause including all its embedded/dependent clauses. Each top-level clausal conjunct, including any embedded/dependent clauses, counts as a T-unit.))+  * subRatio: subordination ratio = (no. of T-units + no. of subordinate clauses) / no. of T-units((T-unit is a main clause including all its embedded/dependent clauses. Each top-level clausal conjunct, including any embedded/dependent clauses, counts as a T-unit.))
   * maxTreeDepth: maximum number of clause embeddings (coordination does not count)   * maxTreeDepth: maximum number of clause embeddings (coordination does not count)
   * mdd: mean dependency distance: average number of word boundaries between words and their heads   * mdd: mean dependency distance: average number of word boundaries between words and their heads
  
 ===== Measures for texts =====  ===== Measures for texts =====

 +The following measures are average values based on the measures for sentences. The mdd value is counted as the average for all words in the text.
 +
 +  * maxNPLengthAvg: average number of words in the longest noun phrase
 +  * maxNPDepthAvg: average number of embeddings in the noun phrase with the longest chain of embeddings 
 +  * sLengthAvg: average sentence length = no. of words in the sentence (punctuation excluded)
 +  * subRatioAvg: average subordination ratio = (no. of T-units + no. of clauses) / no. of T-units
 +  * maxTreeDepthAvg: average maximum number of clause embeddings (coordination does not count)
 +  * mdd: mean dependency distance: average number of word boundaries between words and their heads
 +
 +In addition to syntactic complexity measures each text of sufficient length includes also two measures of [[en:pojmy:lexikalni_bohatost|lexical diversity]].
