如何将 new.bib 与 old.bib 合并，以便 new.bib 使用 old.bib 中的条目名称，用于 new.bib 和 old.bib 中都存在的条目？

我有一个使用 .bib 文件 ( ) 的 LaTeX 项目（一篇研究论文）old.bib。我收到了一个新的 .bib 文件 ( new.bib)，其中包含了 BibTeX 条目，old.bib信息更完整，但有时使用不同的条目名称。

我该如何new.bib与合并，old.bib以便new.bib使用 中的条目名称来表示和old.bib中都存在的条目？请注意，我不想在 中添加任何条目，而只想更改 中也存在的条目的条目名称。new.bibold.bibnew.bibold.bib

示例（实际上我会有更长的.bib 文件）：

输入： new.bib：

@inproceedings{lesterpaper,
  title={The Power of Scale for Parameter-Efficient Prompt Tuning},
  author={Lester, Brian and Al-Rfou, Rami and Constant, Noah},
  booktitle={Empirical Methods in Natural Language Processing},
  pages={3045--3059},
  publisher = {Association for Computational Linguistics},
  year={2021}
}

@article{bommasani2023holistic,
  title={Holistic Evaluation of Language Models},
  author={Bommasani, Rishi and Liang, Percy and Lee, Tony},
  journal={Annals of the New York Academy of Sciences},
  year={2023},
  publisher={Wiley Online Library}
}

old.bib：

@inproceedings{lester,
  title={The Power of Scale for Parameter-Efficient Prompt Tuning},
  author={Lester, Brian and Al-Rfou, Rami and Constant, Noah},
  booktitle={EMNLP},
  publisher = {Association for Computational Linguistics},
  year={2021}
}

@inproceedings{tokpo2022text,
  title={Text Style Transfer for Bias Mitigation using Masked Language Modeling},
  author={Tokpo, Ewoenam Kwaku and Calders, Toon},
  booktitle={NAACL: HLT-SRW},
  pages={163--171},
  publisher = {Association for Computational Linguistics},
  year={2022}
}

输出新new.bib：

@inproceedings{lester,
  title={The Power of Scale for Parameter-Efficient Prompt Tuning},
  author={Lester, Brian and Al-Rfou, Rami and Constant, Noah},
  booktitle={Empirical Methods in Natural Language Processing},
  pages={3045--3059},
  publisher = {Association for Computational Linguistics},
  year={2021}
}

@article{bommasani2023holistic,
  title={Holistic Evaluation of Language Models},
  author={Bommasani, Rishi and Liang, Percy and Lee, Tony},
  journal={Annals of the New York Academy of Sciences},
  year={2023},
  publisher={Wiley Online Library}
}

new.bib示例中新内容的唯一变化是 Bibtex 条目名称lesterpaper更改为lester。

Reddit 用户指挥官 写道这个 Python 脚本基于 Python 库BibTex 解析器根据标题、作者和年份合并两个 Bibtex 文件：

import bibtexparser

#Define bibtex files
old_bib = "old.bib"
new_bib = "new.bib"

#Open bibtex files
with open(old_bib) as bibtex_file:
    old_bib_database = bibtexparser.load(bibtex_file)
old_entries = {entry['ID']: entry for entry in old_bib_database.entries}

with open(new_bib) as bibtex_file:
    new_bib_database = bibtexparser.load(bibtex_file)
new_entries = {entry['ID']: entry for entry in new_bib_database.entries}

#Compare bibtex files
for new_id, new_entry in new_entries.items():
    for old_id, old_entry in old_entries.items():
        #Parameters for bibtex entry comparison
        if old_entry.get('title') == new_entry.get('title') and \
           old_entry.get('author') == new_entry.get('author') and \
           old_entry.get('year') == new_entry.get('year'):
            new_entries[new_id]['ID'] = old_id

#Aggregate merged bibtex information
new_bib_database.entries = list(new_entries.values())

#Throw the bibtex into a new file
with open('merged.bib', 'w') as bibtex_file:
    bibtexparser.dump(new_bib_database, bibtex_file)

这样可行。
