This was achieved by asking a group of people to deliberately write fake positive reviews of properties which were later compared with an equal number of verified truthful reviews. The university says human beings are “lousy” at identifying false reviews online (it asked a judging panel to try), but the software analyses sentiment, word structure and grammar within a review to establish whether it should be flagged up.
