Manoj Lalu, an anaesthesiologist and scientist at The Ottawa Hospital, is helping to develop a label that provides a summary of journal integrity for research papers and journals called the Publication Facts Label, similar to a nutrition-facts label on food. He says Aletheia-Probe is “really nice in some ways, because it gives a very straightforward answer”. He also likes the fact that the software is open source. “You can see what it’s using to make its decision — that’s excellent.” But he cautions that because it relies in part on blacklists that don’t necessarily explain their reasoning, Aletheia-Probe’s output can be opaque. And not everyone is comfortable using a command-line interface, he adds.

Florath says that predatory publishing is a problem even in his original field of mathematics, in which errors can creep in even though correctness should be easy to check. “You stand on the shoulders of giants,” he says, “but currently you don’t know even if these shoulders are sound.” His biggest surprise when developing Aletheia-Probe was how many people were unaware of the problem. “They don’t need to use this [particular] tool,” he says, but they should use something. Instead of automatically assuming all journals are legitimate, Florath says, “it would be really good if people even think about checking”.
