The digital transformation of the scientific publishing industry has led to
dramatic improvements in content discoverability and information analytics.
Unfortunately, these improvements have not been uniform across research areas.
The scientific literature in the arts, humanities and social sciences (AHSS)
still lags behind, in part due to the scale of analog backlogs, the persisting
importance of national languages, and a publisher ecosystem made of many, small
or medium enterprises. We propose a bottom-up approach to support publishers in
creating and maintaining their own publication knowledge graphs in the open
domain. We do so by releasing a pipeline able to extract structured information
from the bibliographies and indexes of AHSS publications, disambiguate,
normalize and export it as linked data. We test the proposed pipeline on
Brill's Classics collection, and release an implementation in open source for
further use and improvement.
