This paper closes this gap: It describes the creation of a training and evaluation set comprised of labeled metadata, evaluates several supervised classification approaches, and comments on their application in scientometric research. The metadata were retrieved from the DataCite index of research data, pre processed, and compiled into a set of 613,585 records. According to our experiments with 20 general fields of study, multi layer perceptron models perform best, followed by long short-term memory models. The models can be used in scientometric research, for example to analyze interdisciplinary trends of digital scholarly output or to characterize growth patterns of research data, stratified by field of study. Our findings allow us to estimate errors in applying the models. The best performing models and the data used for their training are available for re use.", "eprint" : "https://direct.mit.edu/qss/article-pdf/1/2/525/1885831/qss\\_a\\_00049.pdf", "issn" : "2641-3337", "doi" : "10.1162/qss_a_00049", "bibtexKey": "10.1162/qss_a_00049" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/2e8528813e07745135835c57183eabb11/diglezakis", "tags" : [ "artificialIntelligence","subjectIndexing","automated","da-fdm" ], "intraHash" : "e8528813e07745135835c57183eabb11", "interHash" : "fe364d013e08b0e40096b5d479b21a41", "label" : "Künstliche Intelligenz für die Inhaltserschließung \u2013 ein Statusupdate", "user" : "diglezakis", "description" : "", "date" : "2025-03-18 17:19:54", "changeDate" : "2025-03-18 17:19:54", "count" : 1, "pub-type": "article", "journal": "BuB - Forum Bibliothek und Information", "year": "2024", "url": "http://hdl.handle.net/11108/627", "author": [ "Anna Kasprzik" ], "authors": [ {"first" : "Anna", "last" : "Kasprzik"} ], "editor": [ "Berufsverband Information Bibliothek (BIB)" ], "editors": [ {"first" : "Berufsverband Information Bibliothek", "last" : "(BIB)"} ], "volume": "76","number": "08-09","pages": "442-445", "issn" : "1869-1137", "bibtexKey": "kasprzik2024knstliche" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/2ce1acefd67c925d383dd56ed267d22ae/diglezakis", "tags" : [ "subjectIndexing","automated","da-fdm" ], "intraHash" : "ce1acefd67c925d383dd56ed267d22ae", "interHash" : "bbcf5c57404716230fd734d92cb01f40", "label" : "Automated Subject Indexing: An Overview", "user" : "diglezakis", "description" : "", "date" : "2025-03-18 17:14:41", "changeDate" : "2025-03-18 17:14:41", "count" : 2, "pub-type": "article", "journal": "Cataloging & Classification Quarterly","publisher":"Routledge", "year": "2021", "url": "/brokenurl# https://doi.org/10.1080/01639374.2021.2012311 ", "author": [ "Koraljka Golub" ], "authors": [ {"first" : "Koraljka", "last" : "Golub"} ], "volume": "59","number": "8","pages": "702--719", "eprint" : "https://doi.org/10.1080/01639374.2021.2012311", "doi" : "10.1080/01639374.2021.2012311", "bibtexKey": "Golub17112021" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/29dfec68566697d1e6a4d3d11231dbf78/diglezakis", "tags" : [ "subjectIndexing","automated","da-fdm" ], "intraHash" : "9dfec68566697d1e6a4d3d11231dbf78", "interHash" : "0bf432cfaee8f5e0b4475981990fcabc", "label" : "Transferring Applied Machine Learning\r\nResearch into Subject Indexing Practice", "user" : "diglezakis", "description" : "", "date" : "2025-03-18 17:12:26", "changeDate" : "2025-03-24 13:55:16", "count" : 1, "pub-type": "incollection", "booktitle": "New Horizons in Artificial Intelligence in Libraries","publisher":"De Gruyter Saur", "year": "2025", "url": "http://hdl.handle.net/11108/659", "author": [ "Anna Kasprzik" ], "authors": [ {"first" : "Anna", "last" : "Kasprzik"} ], "editor": [ "Edmund Balnaves","Leda Bultrini","Andrew Cox","Raymond Uzwyshyn" ], "editors": [ {"first" : "Edmund", "last" : "Balnaves"}, {"first" : "Leda", "last" : "Bultrini"}, {"first" : "Andrew", "last" : "Cox"}, {"first" : "Raymond", "last" : "Uzwyshyn"} ], "volume": "185","pages": "199-212", "doi" : "10.1515/9783111336435-015", "bibtexKey": "kasprzik2025transferring" } ] }
