==Annotated corpora==
In order to be able to meticulously study the [[English language]], an annotated text corpus was much  needed. The Penn [[Treebank]]<ref>{{cite journal|author1=Marcus, M.|author2=Marcinkiewicz, M.|name-list-style=amp|year=1993|url=https://www.aclweb.org/anthology/J/J93/J93-2004.pdf |archive-url=https://ghostarchive.org/archive/20221009/https://www.aclweb.org/anthology/J/J93/J93-2004.pdf |archive-date=2022-10-09 |url-status=live|title=Building a large annotated corpus of English: The Penn Treebank|journal=Computational Linguistics|volume=19|issue=2|pages=313–330}}</ref> was one of the most used corpora. It consisted of IBM computer manuals, transcribed telephone conversations, and other texts, together containing over 4.5 million words of American English, annotated using both  [[part-of-speech]] tagging and syntactic bracketing.<ref>{{cite book|last1=Taylor|first1=Ann|title=Treebanks|date=2003|publisher=Spring Netherlands|pages=5–22|chapter=1}}</ref>

Japanese sentence corpora were analyzed and a pattern of [[log-normality]] was found in relation to sentence length.<ref name="autogenerated3">{{cite journal|author1=Furuhashi, S.|author2=Hayakawa, Y. |name-list-style=amp|year=2012|title=Lognormality of the Distribution of Japanese Sentence Lengths|journal=Journal of the Physical Society of Japan|volume=81|issue=3|page=034004|doi=10.1143/JPSJ.81.034004|bibcode=2012JPSJ...81c4004F }}</ref>
