  2. 1. Vector Representations of Idioms in Data-Driven Chatbots for Robust Assistance

    Author : Oluwatosin Adewumi; Marcus Liwicki; Foteini Liwicki; Taiwo Kolajo; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; conversational system; chatbot; vectors; data; deep models; Maskininlärning; Machine Learning;

    Abstract : This thesis presents resources capable of enhancing solutions of some Natural Language Processing (NLP) tasks, demonstrates the learning of abstractions by deep models through cross-lingual transferability, and shows how deep learning models trained on idioms can enhance open-domain conversational systems. The challenges of open-domain conversational systems are many and include bland repetitive utterances, lack of utterance diversity, lack of training data for low-resource languages, shallow world-knowledge and non-empathetic responses, among others.

  4. 2. Word Vector Representations using Shallow Neural Networks

    Author : Oluwatosin Adewumi; Marcus Liwicki; Marco Kuhlmann; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Word vectors; NLP; Neural networks; Embeddings; Maskininlärning; Machine Learning;

    Abstract : This work highlights some important factors for consideration when developing word vector representations and data-driven conversational systems. The neural network methods for creating word embeddings have gained more prominence than their older, count-based counterparts. READ MORE
