Generating Natural Anagrams: Towards Language Generation Under Hard Combinatorial Constraints

Abstract

An anagram is a sentence or a phrase that is made by permutating the characters of an input sentence or a phrase. For example, ``Trims cash'' is an anagram of ``Christmas''. Existing automatic anagram generation methods can find possible combinations of words form an anagram. However, they do not pay much attention to the naturalness of the generated anagrams. In this paper, we show that simple depth-first search can yield natural anagrams when it is combined with modern neural language models. Human evaluation results show that the proposed method can generate significantly more natural anagrams than baseline methods.
