[EP-tech] GScholar Export Plugin Issue



Hi All,

   I believe I might have uncovered an issue with the GScholar export plugin packaged with EPrints. Under some situations, citation link values are pulled from adjacent articles in the Google Scholar search result in cases where the target article has no citations. As an example within our repository (http://research.library.mun.ca/1/) the citation link indicates 19 citations, however, clicking the link reveals citations relative to a completely different article. Searching scholar using the query string relative to the article, as built by the ~eprints/perl_lib/EPrints/Plugin/Export/GScholar.pl script segment:

Snip----
87:          $quri->query_form(
88:                                          q => "$title author:$creator"
89:                                          );
Snip----

("Demystifying Open Access author:Goddard") reveals that the citation link is drawn from the article immediately following the target within the search results. Modifying the query structure to more rigidly qualify the title search seems to rectify the issue (at least in this case) e.g.:

Snip----
87:          $quri->query_form(
88:                                          q => "intitle:$title author:$creator"
89:                                          );
Snip----

-- I believe this is the query form applied in the eprints citation count module in: (http://files.eprints.org/641/), however, I'm not sure whether or not there may be any knock-on effects of including the change inside Eprints' GScholar.pm module -- any in the know able to clarify / confirm?

Cheers,
Casey
