Recent advances in neural approaches greatly improve task-oriented dialogue (TOD)
systems which assist users to accomplish their goals. However, such systems rely on costly …

Recently, increasing research interests have focused on retrieval augmented generation
(RAG) to mitigate hallucination for large language models (LLMs). Following this trend, we …

Most existing task-oriented dialog (TOD) systems track dialog states in terms of slots and
values and use them to query a database to get relevant knowledge to generate responses …

The design of conversational user interfaces (CUIs) remains challenging because CUIs do
not follow the conventional ways we conduct graphical user interface (GUI) designs …

Relation Extraction is an important task for personal Natural Language Understanding, and
especially so in conversational applications where Knowledge Graphs, built from such …

With the widespread popularisation of intelligent technology, task-based dialogue systems
(TOD) are increasingly being applied to a wide variety of practical scenarios. As the key …
