Comprehending lyrics, as found in songs and poems, can pose a challenge to
human and machine readers alike. This motivates the need for systems that can
understand the ambiguity and jargon found in such creative texts, and provide
commentary to aid readers in reaching the correct interpretation. We introduce
the task of automated lyric annotation (ALA). Like text simplification, a goal
of ALA is to rephrase the original text in a more easily understandable manner.
However, in ALA the system must often include additional information to clarify
niche terminology and abstract concepts. To stimulate research on this task, we
release a large collection of crowdsourced annotations for song lyrics. We
analyze the performance of translation and retrieval models on this task,
measuring performance with both automated and human evaluation. We find that
each model captures a unique type of information important to the task.

介绍自动歌词注释 (ALA) 任务，旨在通过重新表述原始文本并增加额外信息来帮助读者理解创意文本中的歧义和行话；分析翻译和检索模型在任务上的表现，并发现每个模型捕获任务重要的不同信息类型。
