Over the past two years, computer scientist Cyril Labbé of Joseph Fourier University in Grenoble, France, has catalogued computer-generated papers that made it into more than 30 published conference proceedings between 2008 and 2013. Sixteen appeared in publications by Springer, which is headquartered in Heidelberg, Germany, and more than 100 were published by the Institute of Electrical and Electronic Engineers (IEEE), based in New York. Both publishers, which were privately informed by Labbé, say that they are now removing the papers.Labbé emphasizes that the nonsense computer science papers all appeared in subscription offerings. In his view, there is little evidence that open-access publishers — which charge fees to publish manuscripts — necessarily have less stringent peer review than subscription publishers.

We don’t know what will happen in the case of Springer, but there’s a line in the story about what IEEE have done: ‘the web pages for the removed articles give no explanation for their absence.’
For example, here’s one (the paper ‘TIC: a methodology for the construction of e-commerce’, mentioned in the story): http://ieeexplore.ieee.org/xpl/login.jsp?tp=&arnumber=6626010&url=http%3A%2F%2Fieeexplore.ieee.org%2Fxpls%2Fabs_all.jsp%3Farnumber%3D6626010
As you can see, it just says ‘page not found’. (Although, this paper still has a DOI and is indexed in Scopus, last I checked).
If all the papers are treated like that, then none of these show up as retractions. They simply vanish. Then again, they are entirely worthless nonsense
