Examples of ambigious sentences


I'm looking to test some Morphological Analysis tools, which split sentences
into tokens and provide part of speech and pronunciation information
(specifically, providing kana when given kanji).

I'm after some sentences which automated tools would have trouble with.
Examples of what I'm after are sentences which are difficult to determine the
word boundaries, pronunciation or part of speech. Preferably, examples would
be a more correct interpretation, and be something that could be seen in
actual use.

The best I have found so far is "私はあくまで執事ですから". In a similar vain, is
"にわにはにわとりがいる (庭には二羽鶏が居る)" which only applies to spoken use. An english example
might be something like ["Buffalo buffalo Buffalo buffalo buffalo buffalo
Buffalo
buffalo"](http://en.wikipedia.org/wiki/Buffalo_buffalo_Buffalo_buffalo_buffalo_buffalo_Buffalo_buffalo.),
which is difficult to determine the part of speech each word is.




I've found several webpages online which talk about the sentence `黒い髪のきれいな女の子`
as a famous example of an ambiguous sentence. (For example, [this blog
post](http://blog.query1000.com/archives/17503948.html)).

Here are a couple ways in which this sentence could be considered ambiguous:

  * 女の子 could mean _a female child_ or _a woman's child_.
  * 黒い could modifies 髪, meaning _black hair_ , or it could modify （髪のきれいな）女, meaning _black woman with beautiful hair_ , or it could modify （髪のきれいな女の）子, meaning _black child (of the woman with beautiful hair)_.

Some of the ambiguities, I think, come from reading the sentence in unusual
ways.
