Seminar "Text Mining for Online Social Networks"

On Thursday, May 19, 2022, at 18.00, an online seminar on the topic “Text Mining for Online Social Networks” will be held within the framework of the seminar "Automatic text processing and analysis".
Speaker: Ilya Karpov, Senior Lecturer, School of Data Analysis and Artificial Intelligence, HSE.
Abstract: Applied tasks, such as trends monitoring, fake news detection, sentiment analysis and sarcasm detection, require precise yet generalized models. A significant part of such tasks arises in texts written by users of online social networks, which are more complicated for analysis due to specific vocabulary, typos, and slang. At the seminar we will talk about differences between texts written by online users and professional writers and discuss approach to additional pretraining of generalized language models with social network knowledge injection.
