11. Using word embeddings and domain specific data for information retrieval in the Swedish consumer health domain
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : The amount of information in most of the world’s systems is increasing rapidly. To be able to find relevant information in the vast amount of data, good information retrieval (IR) algorithms are needed. IR algorithms can be constructed and tuned to perform well in different domains. READ MORE

13. Detecting Lexical Semantic Change Using Probabilistic Gaussian Word Embeddings
University essay from Uppsala universitet/Institutionen för lingvistik och filologiAbstract : In this work, we test two novel methods of using word embeddings to detect lexical semantic change, attempting to overcome limitations associated with conventional approaches to this problem. Using a diachronic corpus spanning over a hundred years, we generate word embeddings for each decade with the intention of evaluating how meaning changes are represented in embeddings for the same word across time.

14. General Purpose Vector Representation for Swedish Documents : An application of Neural Language Models
University essay from Umeå universitet/Institutionen för fysikAbstract : This thesis is a proof-of-concept for embedding Swedish documents using continuous vectors. These vectors can be used as input in any subsequent task and serves as an alternative to discrete bag of words vectors. The differences goes beyond fewer dimensions as the continuous vectors also hold contextual information. READ MORE

15. Detecting Anomalies in User Communication in an E-commerce Application : Applying a Clustering Algorithm to VectorizedText Messages
University essay from Uppsala universitet/Institutionen för informationsteknologiAbstract : Many applications that allow text based communication between users are troubled with malicious content. This thesis presents a system for detecting such behaviour in an E-commerce application. The system is based on an algorithm for anomaly detection which is trained using messages sent between users in the application. READ MORE
