I've not read their new paper but the first one was just ridiculous. |
| 20 |
They drew an edge from A to B if A reassigned a bug to B and intepreted |
| 21 |
this as "A knows that B is an expert on the subject". That is just |
| 22 |
ridiculous since A is usually a bug wrangler and B is to be found in |
| 23 |
metadata. For instance the emacs team which gets very few bugs almost |
| 24 |
never appears as B (and certainly not A). This introduces all sorts of |
| 25 |
bias. I think it would be fair to say that their first study had very |
| 26 |
low predictive power and the effects they saw were created by their method. |
