To measure this waste and to reveal end-users\u2019 problem-solving strategies, our research group set up an objective measuring system that can calculate the entropy of digital texts (EDT). To calculate EDT, a testing process of 53 participants was launched where erroneous and correct natural language digital texts were modified according to the requirements of the tasks. It was found that erroneous documents require more time and information to be modified, which implies that waste is generated by handling these documents. It was also found that when the problem-solving processes are broken down into atomic steps, EDT can reveal uncertainty and idleness, which further increases waste. The goals of the present paper are to call attention to (1) the hidden waste generated by billions of end-users and its consequences, (2) educational approaches and general ignorance which have led to these low-level results, and (3) the need to set up a standard evaluation system for further analyses.<\/jats:p>","DOI":"10.3390\/e26121015","type":"journal-article","created":{"date-parts":[[2024,11,25]],"date-time":"2024-11-25T03:59:01Z","timestamp":1732507141000},"page":"1015","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Modification of Erroneous and Correct Digital Texts"],"prefix":"10.3390","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7088-7714","authenticated-orcid":false,"given":"M\u00e1ria","family":"Csernoch","sequence":"first","affiliation":[{"name":"Faculty of Informatics, University of Debrecen, 4032 Debrecen, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0098-7293","authenticated-orcid":false,"given":"Carolin","family":"Hannusch","sequence":"additional","affiliation":[{"name":"Faculty of Informatics, University of Debrecen, 4032 Debrecen, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5997-2515","authenticated-orcid":false,"given":"Piroska","family":"Bir\u00f3","sequence":"additional","affiliation":[{"name":"Faculty of Informatics, University of Debrecen, 4032 Debrecen, Hungary"},{"name":"Faculty of Economics, Socio-Human Sciences and Engineering, Sapientia Hungarian University of Transylvania, 530104 Miercurea-Ciuc, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,11,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Panko, R.R.
