Computational knowledge engine Wolfram Alpha is taking a leaf out of Wikipedia's virtual book with the search for "volunteer curators".

"If you're as excited about Wolfram Alpha as we are, and want to help out, consider becoming a volunteer curator", the site says in a blog post.

"Our volunteer curators are passionate, enthusiastic people who are committed to gathering and checking data".

Currently Wolfram Alpha has volunteer curators across the globe supplying geographical data, but is opening the scheme up to volunteers "with different interests or areas of expertise as well".

Wolfram Alpha says: "If you've got knowledge or insight into a specific area, we want to hear from you".
