The ability to automatically send documents for similarity checking is currently in development!
We are working on an integration with Ephorus, a popular similarity checking software which has a large user base in Europe and is gaining many users in the UK. This integration will mean you can create assignments in FASer that will automatically check the similarity of all or a portion of submissions after the deadline. It checks against millions of web pages and online journals, as well as comparing documents with previously submitted items. Academics and administrators will be able to see at a glance what percentage of a document has been matched against something else and see a report detailing what bits are similar to another document and the source of the match.
Development is fully underway with a plan to release the functionality at the beginning of July.
