1. 36. Anchor-based Topic Modeling with Human Interpretable Results

   University essay from Linköpings universitet/Interaktiva och kognitiva system

   Author : Henrik Andersson; [2020]
   Keywords : topic models; anchor-based; anchor words; efficient; human interpretable;

   Abstract : Topic models are useful tools for exploring large data sets of textual content by exposing a generative process from which the text was produced. Anchor-based topic models utilize the anchor word assumption to define a set of algorithms with provable guarantees which recover the underlying topics with a run time practically independent of corpus size.

3. 37. Context matters : Classifying Swedish texts using BERT's deep bidirectional word embeddings

   University essay from Linköpings universitet/Institutionen för datavetenskap

   Author : Daniel Holmer; [2020]
   Keywords : NLP; text classification; BERT; feature representation; pre-trained language models; transformer networks; fine-tuning;

   Abstract : When classifying texts using a linear classifier, the texts are commonly represented as feature vectors. Previous methods to represent features as vectors have been unable to capture the context of individual words in the texts, in theory leading to a poor representation of natural language. READ MORE

6. 40. 'Sorry, I didn't understand that' : A comparison of methods for intent classification for social robotics applications

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Mikaela Åstrand; [2020]
   Keywords : ;

   Abstract : An important feature in a social robot is the ability to understand natural language. One of the core components in a typical system for natural language understanding (NLU) is so called intent classification; the action of classifying user utterances based on the underlying intents of the user.
