In the 1960s, statisticians and economists used terms like ''data fishing'' or ''data dredging'' to refer to what they considered the bad practice of analyzing data without an a-priori hypothesis. The term "data mining" was used in a similarly critical way by economist [[Michael Lovell]] in an [article|https://www.jstor.org/stable/1924403?seq=1#page_scan_tab_contents] published in the [[Review of Economic Studies]] 1983
The term ''data mining'' appeared around 1990 in the database community, generally with positive connotations. For a short time in 1980s, a phrase "database mining"™, was used, but since it was trademarked by HNC, a San Diego-based company, to pitch their Database Mining Workstation;<ref name="Mena">{{cite book |last=Mena |first=Jesús |year=2011 |title=Machine Learning Forensics for Law Enforcement, Security, and Intelligence |location=Boca Raton, FL |publisher=CRC Press (Taylor & Francis Group) |isbn=978-1-4398-6069-4 }}</ref> researchers consequently turned to ''data mining''. Other terms used include ''data archaeology'', ''information harvesting'', ''information discovery'', ''knowledge extraction'', etc. [[Gregory I.
