Regex from the paper?

[turian]

Can you please include, at least in the documentation, the regex from the paper?

In this code, the "standard is to only select keyphrases that have 0 or more adjectives, followed by 1 or more nouns."

In the paper, the POS pattern is "arbitrary parts-of-speech separated by a hyphen, followed by zero or more nouns
OR zero or one verb (gerund or present or past participle), followed by zero or more adjectives, followed
by one or more nouns"
