Is there a way to obtain a dataset consisting of LinkedIn data? Is there any existing open dataset for this purpose? If no, can I collect the data using LinkedIn API?
[to be eligible] your Application WILL NOT store or export any data from LinkedIn other than the LinkedIn Profile Data for the LinkedIn member that requested the data. “Profile Data” means the name, photo, headline, contact information, experience, education, summary, and location of a LinkedIn member. Profile Data excludes connections, network updates, job listings, groups, companies, and any other content.
This suggests that there is no open data set, or if there were, it would be violating LinkedIn's intended use for the data. Of course, it's not a definitive answer, but that is not uncommon for posts in the "data-request" tag.
