ELSEVIER has many well known ISI indexed journals with poor review quality. Expert Systems with Applications is just an example of it. They used to publish 100 papers per month with no peer review insights. The papers were either rejected or accepted and there was no comments. Here are some of the facts on publishing on OA journals
1. Your paper has up to six times more chance to get cited.
2. The scientific society pays less. Note that publishing a paper in non-OA costs well over 5000$ per article and this cost is reduced to 200-1500 depending on OA publisher.
I agree that there are many OA publishers trying to abuse the whole idea but we should keep in our mind that sooner or later, all publishers must switch to OA model and this help world’s scientific society grow faster.
