These techniques analyze questions at the lexical, syntactic, and semantic levels, exposing differences in both form and content.<\/jats:p><jats:p>Results Consumer questions tend to be longer than professional questions, more closely resemble open-domain language, and focus far more on medical problems. Consumers ask more sub-questions, provide far more background information, and ask different types of questions than professionals. Furthermore, there is substantial variance of these factors between the different consumer corpora.<\/jats:p><jats:p>Discussion The form of consumer questions is highly dependent upon the individual online resource, especially in the amount of background information provided. Professionals, on the other hand, provide very little background information and often ask much shorter questions. The content of consumer questions is also highly dependent upon the resource. While professional questions commonly discuss treatments and tests, consumer questions focus disproportionately on symptoms and diseases. Further, consumers place far more emphasis on certain types of health problems (eg, sexual health).<\/jats:p><jats:p>Conclusion Websites for consumers to submit health questions are a popular online resource filling important gaps in consumer health information. By analyzing how consumers write questions on these resources, we can better understand these gaps and create solutions for improving information access.<\/jats:p><jats:p>This article is part of the Special Focus on Person-Generated Health and Wellness Data, which published in the May 2016 issue, Volume 23, Issue 3.<\/jats:p>","DOI":"10.1093\/jamia\/ocw024","type":"journal-article","created":{"date-parts":[[2016,5,5]],"date-time":"2016-05-05T03:16:25Z","timestamp":1462418185000},"page":"802-811","source":"Crossref","is-referenced-by-count":37,"title":["Interactive use of online health resources: a comparison of consumer and professional questions"],"prefix":"10.1093","volume":"23","author":[{"given":"Kirk","family":"Roberts","sequence":"first","affiliation":[{"name":"Lister Hill National Center for Biomedical Communications, US National Library of Medicine, National Institutes of Health 8600 Rockville Pike, Building 38A\/1003H Bethesda, MD, 20894, USA"}]},{"given":"Dina","family":"Demner-Fushman","sequence":"additional","affiliation":[{"name":"Lister Hill National Center for Biomedical Communications, US National Library of Medicine, National Institutes of Health 8600 Rockville Pike, Building 38A\/1003H Bethesda, MD, 20894, USA"}]}],"member":"286","published-online":{"date-parts":[[2016,5,4]]},"reference":[{"key":"2020110612385701700_ocw024-B1","doi-asserted-by":"crossref","DOI":"10.1007\/0-387-27652-1","volume-title":"Consumer Health Informatics: Informing Consumers and Improving Health Care","author":"Lewis","year":"2005"},{"issue":"3","key":"2020110612385701700_ocw024-B2","doi-asserted-by":"crossref","first-page":"193","DOI":"10.1016\/j.ijmedinf.2012.09.008","article-title":"Internet health information seeking is a team sport: Analysis of the Pew Internet Survey","volume":"82","author":"Sadasivam","year":"2013","journal-title":"Int J Med Inform."},{"issue":"5","key":"2020110612385701700_ocw024-B3","doi-asserted-by":"crossref","first-page":"710","DOI":"10.1001\/jamainternmed.2014.368","article-title":"Clinical questions raised by clinicians at the point of care: a systematic review","volume":"174","author":"Del Fiol","year":"2014","journal-title":"JAMA Intern Med."},{"key":"2020110612385701700_ocw024-B4","doi-asserted-by":"crossref","first-page":"49","DOI":"10.1136\/amiajnl-2012-001473","article-title":"From health search to health care: explorations of intention and utilization via query logs and user surveys","volume":"21","author":"White","year":"2014","journal-title":"J Am Med Inform Assoc."},{"issue":"1","key":"2020110612385701700_ocw024-B5","doi-asserted-by":"crossref","first-page":"24","DOI":"10.1197\/jamia.M1761","article-title":"Exploring and developing consumer health vocabularies","volume":"13","author":"Zeng","year":"2006","journal-title":"J Am Med Inform Assoc."},{"key":"2020110612385701700_ocw024-B6","first-page":"697","article-title":"In Their Own Words?
