          <datacite:description descriptionType="Other">In this paper the author describes how to finetune sequence-labeling for part-of-speech tagging and dependency-parsing, using Japanese causal language models, such as GPT, LLaMA and Qwen. For part-of-speech tagging, we utilize Bellman-Ford algorithm to refine the sequence-labeling. For dependency-parsing, the author has developed an original sequence-labeling algorithm, in which leftward edges are treated reversely. The author investigates efficiency of the algorithms, applying them to twenty-seven Japanese causal language models.</datacite:description>
