Using Web of Science to look for Highly Cited Papers and Hot Papers (YouTube, 2m16s) demonstrates how to identify if you have one or more of these types of papers indexed in Web of Science:
Essential Science Indicators (ESI) identifies papers in the Web of Science Core Collection that are producing a lot of impact when compared to peers (papers in the same field, same publication date). If your paper has been identified as a Highly Cited Paper or Hot Paper, there will be an icon next to your paper to designate this status. Note: A paper can be both Highly Cited and Hot.
Highly Cited Papers are papers published in the last 10 years that are receiving the most citations (top 1%) when compared to peer papers (same field, same publication year).
Hot Papers are papers published in the last two years that are receiving the most citations (top 0.1%) in the most recent two-month period when compared to peer papers (same field, same publication date).
Note: Papers identified as Highly Cited or Hot can change over time, as the ESI database updates every 2 months. It is recommended that you check regularly for these papers, and take screenshots, recording the date of capture where relevant.
