Short Paper accepted at ECML/PKDD 2018
We are very pleased to announce that our group got a short paper accepted for presentation at ECML/PKDD 2018 (nectar track) : The European Conference on Machine Learning and Principles and Practice of Knowledge Discovery in Databases will take place in the Croke Park Conference Centre, Dublin, Ireland during the 10 – 14 September 2018. This event is the premier European machine learning and data mining conference and builds upon over 16 years of successful events and conferences held across Europe. reland is delighted to host and to bring together participants to Croke Park- one of the iconic sporting venues but also providing a world-class conference facility. Here is the accepted paper with its abstract:
- “Deep Query Ranking for Question Answering over Knowledge Bases” by Hamid Zafar, Giulio Napolitano, and Jens Lehmann (Nectar track)
Abstract: We study question answering systems over knowledge graphs which map an input natural language question into candidate formal queries. Often, a ranking mechanism is used to discern the queries with higher similarity to the given question. Considering the intrinsic complexity of the natural language, finding the most accurate formal counter-part is a challenging task. In our recent paper, we leveraged Tree-LSTM to exploit the syntactical structure of input question as well as the candidate formal queries to compute the similarities. An empirical study shows that taking the structural information of the input question and candidate query into account enhances the performance, when compared to the baseline system.Acknowledgment This research was supported by EU H2020 grants for the projects HOBBIT (GA no. 688227) and WDAqua (GA no. 642795) as well as by German Federal Ministry of Education and Research (BMBF) funding for the project SOLIDE (no. 13N14456).
Looking forward to seeing you at The TPDL 2018.
