Data for: HClaimE: A Tool to Identify Health Claims in Health News Headlines

This data set contains 564 health research news headlines with manual annotations of the health claims in the headlines and metadata such as publication dates and sources. The headlines were selected from news articles published on ScienceDaily.com from January 2016 to June 2017, including 212 headlines on breast cancer and 352 on diabetes. The news articles came from 286 different sources, such as Scripps Research Institute.

Among the 564 headlines, 416 contain health claims, while the other 148 headlines do not.
