A citation-based method for searching scientific literature


For which browsers are CoCites extensions available?
CoCites is only available for Chrome and Firefox.

I downloaded the extension but see no CoCites buttons in PubMed.
Make sure the URL of PubMed is https://www.ncbi.nlm.nih.gov/pubmed/ or https://pubmed.ncbi.nlm.nih.gov/.

What number is in the CoCites button on PubMed?
The number of citations. CoCites works best when articles are cited more than 20 times, but works to find at least some relevant articles when the number is lower. A zero indicates that the article is not cited (yet).

What does a grey CoCites button on PubMed mean?
The article is not found in the citation database. This mostly happens to articles that are published recently.

Why does CoCites only use the 100 most recent citations?
At this moment, CoCites uses the 100 most recent citations to limit the impact on the server capacity. Our research showed that limiting to 100 citing articles improved efficiency without compromising the sensitivity of search results (manuscript in preparation).

What do CoCited and Similarity mean in the search results?
CoCited is the co-citation frequency, the number of articles that cite both the query article and the article in the results. Similarity is a relative co-citation frequency, as percentage of the number of citations of the query article or the article in the search results, whichever is lowest. In a next version, the co-citation frequency will link to the list of articles and similarity will be available as a search filter (or export the search results to filter in Excel).

What is the data source behind CoCites?
CoCites uses the NIH Open Citation Collection (NIH-OCC).
