What citing_author holds? An equivalent to data points for citedby:author:lagra? Not practical to store stuff like that next to every record. Note that citedby/refersto operators can operate on any query, not only on authors. See my `refersto:keyword:muon' example. > the lucene query with the same effect then is: > > ((author:ellis +citedby:witten -author:witten) +keyword:muon) --> > cluster_by(len(cited)) Not quite. `refersto:keyword:muon' gives you a set of papers that cite some paper from the set of papers that are tagged with keyword muon. Gives 93k hits on INSPIRE. To be compared to the set of papers tagged with keyword muon, 22k hits on INSPIRE. > notes: > - citedby:author:witten -- it doesnt make sense to me that it could > be sb else than other author Note sure what you mean. Gives collection of all papers that are cited by any of the paper written by Witten. It could be any author, including Witten itself (think self-cites). Try it on INSPIRE. > - 2nd order links must be carefully prepared (but honestly, how many > of those 2nd order relations are really needed, and really used? this > number is probably low...) Cite summary, co-cited with, etc are all second-order operations. Best regards -- Tibor Simko
