Answer 1

您可以使用Stanford Natural Language Parser。

require "stanfordparser"

input = 'Ruby is a dynamic, reflective, object-oriented, general-purpose programming language. It was designed and developed in the mid-1990s by Yukihiro "Matz" Matsumoto in Japan. According to its authors, Ruby was influenced by Perl, Smalltalk, Eiffel, Ada, and Lisp.'
preproc = StanfordParser::DocumentPreprocessor.new
puts preproc.getSentencesFromString(input)
# Ruby is a dynamic, reflective, object-oriented, general-purpose programming language. 
# It was designed and developed in the mid-1990s by Yukihiro "Matz" Matsumoto in Japan. 
# According to its authors, Ruby was influenced by Perl, Smalltalk, Eiffel, Ada, and Lisp.

使用正则表达式：

puts input.split(/((?<=[a-z0-9)][.?!])|(?<=[a-z0-9][.?!]"))\s+(?="?[A-Z])/)
# Ruby is a dynamic, reflective, object-oriented, general-purpose programming language.
#
# It was designed and developed in the mid-1990s by Yukihiro "Matz" Matsumoto in Japan.
# 
# According to its authors, Ruby was influenced by Perl, Smalltalk, Eiffel, Ada, and Lisp.

注意：我假设输入字符串中.和According之间有空格。
