*Education and Mentorship
**Accelerators differ from incubators and angel investors in that they emphasize the education of the potential startup. They offer advice and intense mentorship from more experienced entrepreneurs within their staff, as well as many networking opportunities with the outside world. This variable is more difficult to find on the website of the accelerator, but I believe that if the website includes numerous keywords such as "education", "mentorship", or "networking opportunities", it would be somewhat safe to assume that the website is owned by an accelerator.
A combination of any of these variables would very close to certainly identify the current website as belonging to an accelerator.
