Photo. Peng Liu.Peng works as a postdoctoral fellow at the Norwegian Research Center for AI Innovation (NorwAI) at NTNU, and started in December 2020.  He is now working on Large-Scale Norwegian Language Models in various applications which is the first “deep dive” innovation project at NorwAI.org.

Peng is from Beijing, China and studied at Peking University before he became Research Fellow at NTNU in 2015 working on the RecTech project. He obtained his PhD in computer science from NTNU with a thesis focused on effective context-aware recommendation approaches for the social media domain.

His research topic is natural language processing and recommender systems. His primary interests lie in the areas of sentiment analysis, topic modeling, lexical semantics, and recommendation algorithms based on data streams and multimodal contexts such as text, image etc. Peng has multiple publications in his field, including a Best Paper at ACM Hypertext 2018.


Meet Benjamin Kille, a new NTNU postdoctoral fellow, associated to NorwAI

Meet Benjamin Kille, a new NTNU postdoctoral fellow, associated to NorwAI

Photo. Benjamin KilleBenjamin Kille joined NTNU and the Department of Computer Science as a postdoctoral fellow just recently, from 1st May. He is a member of the AI/Big Data collaboration project between DNB and NTNU, and his work will be closely connected to the work packages on language technologies and recommender systems in NorwAI. Benjamin is at the moment working from Berlin, but we are looking forward to welcoming him in Trondheim as soon as traveling restrictions allow.

Before joining NTNU, Benjamin has been a member of the Information Retrieval and Machine Learning group at the DAI-Lab of Technische Universität Berlin (TU Berlin, www.tu.berlin). He worked on research projects in various domains, including natural language processing, dialog systems, recommender systems, data processing and visualization, and machine learning. Benjamin has just completed his PhD at TU Berlin. His dissertation has investigated context-awareness for news recommender systems. He co-organized a series of workshops (INRA) and data-driven competitions (NewsREEL, MediaEval), which provide a forum to discuss advances in personalized information access. Besides, he is highly interested in research concerning complex systems and explainable artificial intelligence (XAI). He was born in Villingen, is a small city in Baden-Württemberg in Germany. He did his master in Karlsruhe at Karlsruher Institut für Technologie (KIT, www.kit.edu). During his masters he spent a couple of semesters in Stockholm at KTH Royal Institute of Technology. He also ended up writing his master thesis at KTH
