Delighted to share that our full paper on „Faithful Temporal Question Answering over Heterogeneous Sources“ got accepted at The Web Conference 2024!
Joint work with @ZhenJia9 (first author) and Gerhard Weikum.

Looking forward to traveling to Singapore in May!

I will present our work on „Explainable Conversational QA over Heterogeneous Sources via Iterative Graph Neural Networks“ tomorrow at 9 AM in the „Conversational search and recommendation“ session at #SIGIR2023 in Taipei. Joint work with @RishirajSahaRoy and Gerhard Weikum.

@d_aumiller @RishirajSahaRoy CLOCQ can provide disambiguations and relevant KB-facts. If the KB-facts are not required, they can be left untouched. The 370 GB memory requirement is only for the server, which loads a whole Wikidata dump in memory (~2TB originally). The client doesn't require (much) memory.

@ZhenJia9 @RishirajSahaRoy @SIGIRConf Thanks @ZhenJia9!

Just gave a talk on how our #WSDM22 work CLOCQ (with @RishirajSahaRoy and Gerhard Weikum) can be used for entity and relation linking in the SMART Task 3.0. Thanks for the opportunity @nand_ai @MohnishDubey @debayan et al. Links: https://t.co/KsNNrBjsDy, https://t.co/hvILsCpmDX

@RishirajSahaRoy Thanks a lot Rishi! Definitely a result of the many research discussions we had in the last four years, and your great work as a supervisor! :)

Finally we have the #mpireloaded pic. Tried photoshopping @lauradietz99 in but it’s best to have two pics .. #mpii #sigir2022 .. had a great time catching up with old friends and meeting new colleagues. Adios Madrid.

I will present our #SIGIR2022 paper on „Conversational Question Answering on Heterogeneous Sources“ tomorrow in the Conversational IR session in Madrid. Joint work with @RishirajSahaRoy and Gerhard Weikum. Link to paper: https://t.co/vX61EDPJRC. #SIGIR

[Philipp Christmann @PhilippChr97]

The code and data for our #SIGIR2022 paper "Conversational Question Answering on Heterogeneous Sources" (with @RishirajSahaRoy and Gerhard Weikum), including the new ConvMix benchmark, are now available on the project website: https://t.co/zNMfIlyrHb. #SIGIR #questionanswering

@DrCh0le Thank you!

[Philipp Christmann @PhilippChr97]

Very happy that my doctoral consortium paper on „Explainable Conversational Question Answering over Heterogeneous Sources“ has been accepted at #SIGIR2022 as well.
Looking forward to the discussions in Madrid!
