*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.
*Demo Day
**This variable does not have tremendous potential in terms of crawling websites, but I feel that it is worth mentioning. Most accelerators "graduate" their cohorts with a demo day, which is a day when the startups present their company to potential investors. If the website contains the words "demo day", which is fairly uncommon, it could be a good source of accelerator identification.
