Compute the riq-index for an author on InspireHep.net

The Research Impact Quotient (riq) is the ratio of the square-root of the Total Research Impact (tori) to the number of years since the date of the first publication of the author. (See arxiv:1209.2124 for more details.) This script presents the "riq index", taken to be 1000 times the riq, based on the data available on inspirehep.net. Thus, it is intended for people in high energy physics and related fields.

Note that in computing the tori, self-citations are removed only in the cases that the author for whom we are computing the riq index is an author of the citing article. I.e. if paper A by X and Y is cited by paper B by Y alone, we do not consider paper B a self-cite when computing the tori of X. (However, it would be excluded for the tori of Y.)

The main speed limitation is the way in which bibliography lengths must be determined. On InspireHep, there is (as far as I know) no way to query the number of references of a record directly. This script works by obtaining the MARCXML of every citing article, then counting the number of bibliography entries. An alternate strategy might be to download the XHTML output and parsing out the number cached by InspireHep. (I'll see how much faster it is and update if it's worth it.)
