Joint Named Entity Recognition and Stance Detection in Tweets

Understand

Named entity recognition (NER) is a well-established task of information extraction which has been studied for decades.

• More recently, studies reporting NER experiments on social media texts have emerged.
• On the other hand, stance detection is a considerably new research topic usually considered within the scope of sentiment analysis.
• Stance detection studies are mostly applied to texts of online debates where the stance of the text owner for a particular target, either explicitly or implicitly mentioned in text, is explored.
