  • The 2nd Heidelberg Summer School of Computational Humanities (HCH19) has just ended, with lectures, workshops and special events around Mixed Methods in the Computational Humanities. Co-organized by teams of Beatrix Busse, Anette Frank and the Leibniz ScienceCampus. Thanks to all contributors and participants!
  • Juri Opitz and Leo Born offered a half-day hands-on tutorial and workshop: Providing new views on textual data with knowledge graphs at HCH19 (details to come).
  • New publication on "Dissecting Content and Context in Argumentative Relation Analysis", by Juri Opitz and Anette Frank, to appear at the 6th Argument Mining Workshop at ACL 2019 in Florence.
  • New publications at NAACL, *SEM, DATeCH, LDK and RELATIONS!
  • We launched a new NLP blog, which is open to interested students and researchers to share views, insights and news about research in Natural Language Processing, Computational Linguistics and Artificial Intelligence.
