Since the Dartmouth Conference in 1956, which was an essential date for AI research, 66 have passed. Where will the next 66 years take us? In our blog post, Prof. Jens Lehmann describes his view on the future development of AI: medium.com/p/16dd2b7b7e55 #ArtificialIntelligence

Since the Dartmouth workshop in 1956, which is often seen as the funding event for Artificial Intelligence as a field, 66 years have passed. How will AI evolve in the next 66 years? This is what I cover in my new blog post: jens-lehmann.org/blog/the-next-… #ArtificialIntelligence #humans

Very honoured by this award. Thanks to my co-authors @ClausStadler Konrad Höffner and @SoerenAuer!

SWJ 10-year award 2022: Claus Stadler, Jens Lehmann, Konrad Höffner, and Sören Auer, LinkedGeoData: A Core for a Web of Spatial Open Data. Semantic Web 3 (4), 2012, 333-354 @ClausStadler @JLehmann82 @SoerenAuer @STKO_UCSB @pascalhitzler @IOSPress_STM semantic-web-journal.net/blog/semantic-…

I'm happy to share that TU Dresden has appointed me to an honorary professorship position. This will allow me to perform some research and teaching activities in my spare time next to the main work at Amazon. More information is in the press release here: tu-dresden.de/ing/informatik…

We are thrilled to announce that our group leader @JLehmann82 and his co-authors won the SWJ 10-year award 2022 for their work "LinkedGeoData: A Core for a Web of Spatial Open Data". Paper: jens-lehmann.org/files/2012/lin…

We are looking for talented scientists to work at Amazon Alexa AI in Dresden/Germany! If you are interested in machine learning, knowledge graphs, NLP & language models, please consider to apply at amazon.jobs/en-gb/jobs/217… (researchers at different experience levels can apply).

Do you want to compute dataset statistics for large-scale OWL datasets? Then check out OWLStats, a distributed in-memory approach for computing 50 statistical criteria for OWL datasets utilizing Apache Spark. More details at: sda.tech/paper-accepted… #semanticweb

I am extremely excited to join @amazon @alexa99 AI today and start a new chapter in my scientific career working in an excellent environment on question answering, knowledge graphs, reasoning, natural language understanding and more generally the future of conversational AI.

Evaluating Natural Language Generation (#NLG) 💬systems is a challenging task. In our #ACL22 paper, we present our contribution to addressing this challenge: RoMe, a robust metric for evaluating NLG📈. More details at: sda.tech/paper-acceoted… #machinelearning #conversationalai

Congratulations to Denis @lukovnikov for successfully defending his PhD thesis today! Denis worked on deep learning for question answering and semantic parsing. He analysed & improved transfer learning, compositionality and generalisation of large-scale machine learning models.

Congratulations to Debanjan ( @deepinevil ) for successfully defending his PhD thesis today! Debanjan worked on integrating background knowledge into question answering & dialogue systems to increase the factual accuracy of chatbots while allowing very natural sounding dialogues.

Congratulations to @SebastianBade18 for successfully defending his PhD thesis. Sebastian skillfully combined semantic and IoT technologies to address practical challenges via Semantic Digital Twins. His work influenced standardisation activities and implementations in industry.

Do you want to evaluate the #linkprediction capabilities of your #knowledgegraphembeddingmodel on a diverse set of datasets? Then check out our recent #NeurIPS paper in which we present a novel set of datasets: sda.tech/paper-accepted… #machinelearning #knowledegegraphs
