Lojban, the constructed language, features:

a) logical grammar, inspired by predicate logic which means every sentence in Lojban has an unambiguous structure that a computer can parse

b) no ambiguity in the grammar (structural ambiguity) while you can be as vague or detailed as you like (or as funny!!)

c) emotional expressions via an "attitudinal" system of words that function like emoji
