Representing Features
Various linguistic features can also be represented fairly concisely with DCGs by providing extra arguments to the functors. For example, consider the following set of DCG rules:
sentence --> pronoun(subject), verb_phrase. verb_phrase --> verb, pronoun(object). pronoun(subject) --> . pronoun(subject) --> . pronoun(object) --> . pronoun(object) --> . verb --> .This grammar allows sentences like "he likes her" and "he likes him", but not "her likes he" and "him likes him".
