However, citation context analysis\u0000requires creating large amounts of data through annotation, which hinders the\u0000widespread use of this methodology. This study explored the applicability of\u0000Large Language Models (LLMs) -- particularly ChatGPT -- to citation context\u0000analysis by comparing LLMs and human annotation results. The results show that\u0000the LLMs annotation is as good as or better than the human annotation in terms\u0000of consistency but poor in terms of predictive performance. Thus, having LLMs\u0000immediately replace human annotators in citation context analysis is\u0000inappropriate. However, the annotation results obtained by LLMs can be used as\u0000reference information when narrowing the annotation results obtained by\u0000multiple human annotators to one, or LLMs can be used as one of the annotators\u0000when it is difficult to prepare sufficient human annotators. This study\u0000provides basic findings important for the future development of citation\u0000context analyses.","PeriodicalId":501285,"journal":{"name":"arXiv - CS - Digital Libraries","volume":"65 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142219102","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An important step in this process is\u0000converting scanned images to text using Optical Character Recognition (OCR),\u0000which can enable further search, information extraction, etc. Unfortunately,\u0000this is a hard problem as standard OCR tools are not tailored to deal with\u0000historical orthography as well as with challenging layouts. Thus, it is\u0000standard to apply an additional text correction step on the OCR output when\u0000dealing with such documents. In this work, we focus on Bulgarian, and we create\u0000the first benchmark dataset for evaluating the OCR text correction for\u0000historical Bulgarian documents written in the first standardized Bulgarian\u0000orthography: the Drinov orthography from the 19th century. We further develop a\u0000method for automatically generating synthetic data in this orthography, as well\u0000as in the subsequent Ivanchev orthography, by leveraging vast amounts of\u0000contemporary literature Bulgarian texts. We then use state-of-the-art LLMs and\u0000encoder-decoder framework which we augment with diagonal attention loss and\u0000copy and coverage mechanisms to improve the post-OCR text correction. The\u0000proposed method reduces the errors introduced during recognition and improves\u0000the quality of the documents by 25%, which is an increase of 16% compared to\u0000the state-of-the-art on the ICDAR 2019 Bulgarian dataset.

{"title":"CLOCR-C: Context Leveraging OCR Correction with Pre-trained Language Models","authors":"Jonathan Bourne","doi":"arxiv-2408.17428","DOIUrl":"https://doi.org/arxiv-2408.17428","url":null,"abstract":"The digitisation of historical print media archives is crucial for increasing\u0000accessibility to contemporary records. However, the process of Optical\u0000Character Recognition (OCR) used to convert physical records to digital text is\u0000prone to errors, particularly in the case of newspapers and periodicals due to\u0000their complex layouts. This paper introduces Context Leveraging OCR Correction\u0000(CLOCR-C), which utilises the infilling and context-adaptive abilities of\u0000transformer-based language models (LMs) to improve OCR quality. The study aims\u0000to determine if LMs can perform post-OCR correction, improve downstream NLP\u0000tasks, and the value of providing the socio-cultural context as part of the\u0000correction process. Experiments were conducted using seven LMs on three\u0000datasets: the 19th Century Serials Edition (NCSE) and two datasets from the\u0000Overproof collection. The results demonstrate that some LMs can significantly\u0000reduce error rates, with the top-performing model achieving over a 60%\u0000reduction in character error rate on the NCSE dataset. The OCR improvements\u0000extend to downstream tasks, such as Named Entity Recognition, with increased\u0000Cosine Named Entity Similarity. Furthermore, the study shows that providing\u0000socio-cultural context in the prompts improves performance, while misleading\u0000prompts lower performance. In addition to the findings, this study releases a\u0000dataset of 91 transcribed articles from the NCSE, containing a total of 40\u0000thousand words, to support further research in this area. The findings suggest\u0000that CLOCR-C is a promising approach for enhancing the quality of existing\u0000digital archives by leveraging the socio-cultural information embedded in the\u0000LMs and the text requiring correction.","PeriodicalId":501285,"journal":{"name":"arXiv - CS - Digital Libraries","volume":"38 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142219106","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
