To address such problems, the goal of this paper is to develop a new approach for document-level relationship extraction by applying a new idea through the consideration of so-called \u201cLocal Relationship and Global Inference\u201d (in short, LRGI), which means that we first encode the text using the BERT pre-training model to obtain a local relationship vector first by considering a local context pooling and bilinear group algorithm and then establishing a global inference mechanism based on Floyd\u2019s algorithm to achieve multi-path multi-hop inference and obtain the global inference vector, which allow us to extract multi-classified relationships with adaptive thresholding criteria. Taking the DocRED dataset as a testing set, the numerical results show that our proposed new approach (LRGI) in this paper achieves an accuracy of 0.73, and the value of F1 is 62.11, corresponding to 28% and 2% improvements by comparing with the classical document-level relationship extraction model (ATLOP), respectively.<\/jats:p>","DOI":"10.3390\/info14070365","type":"journal-article","created":{"date-parts":[[2023,6,28]],"date-time":"2023-06-28T00:45:11Z","timestamp":1687913111000},"page":"365","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Document-Level Relation Extraction with Local Relation and Global Inference"],"prefix":"10.3390","volume":"14","author":[{"given":"Yiming","family":"Liu","sequence":"first","affiliation":[{"name":"School of Electronic and Electrical Engineering, Shanghai University of Engineering Science, Shanghai 201620, China"}]},{"given":"Hongtao","family":"Shan","sequence":"additional","affiliation":[{"name":"School of Electronic and Electrical Engineering, Shanghai University of Engineering Science, Shanghai 201620, China"}]},{"given":"Feng","family":"Nie","sequence":"additional","affiliation":[{"name":"School of Finance, Shanghai Lixin University of Accounting and Finance, Shanghai 201209, China"}]},{"given":"Gaoyu","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Information Management, Shanghai Lixin University of Accounting and Finance, Shanghai 201209, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6186-9162","authenticated-orcid":false,"given":"George Xianzhi","family":"Yuan","sequence":"additional","affiliation":[{"name":"College of Science, Chongqing University of Technology, Chongqing 400054, China"},{"name":"Business School, Chengdu University, Chengdu 610106, China"}]}],"member":"1968","published-online":{"date-parts":[[2023,6,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Yu, M., Yin, W., Hasan, K.S., Santos, C.D., Xiang, B., and Zhou, B.
