Welcome to the AI4LT

The "Artificial Intelligence for Language Technologies (AI4LT)" lab at the Institute for Anthropomatics und Robotics (IAR) develops language technologies that enable human-computer interaction and support human-human interaction using deep learning. The lab investigates the research areas: machine translation, speech translation, automatic speech recognition and dialog modelling. The lab is headed by Prof. Dr. Jan Niehues.

2 papers at NAACL on LLMs for machine translation post-editing and zero-shot summarization

In the NAACL conference in June 2024, our group is presenting two papers. One is on using LLMs for post-editing machine translation outputs. This work results from our collaboration with SAP. The other paper is on improving multilingual pretrained models for zero-shot summarization. This is based on the thesis project of our alumnus Vladimir. Congrats to all authors!

3 papers at LREC-COLING

Looking forward to presenting 3 papers in the LREC-COLING conference in May 2024! At the main conference, we have one paper on speech recognition for endangered languages, and another paper on evaluation of speech translation performance. We are also proud that our thesis alumnus Ari is presenting his work on creating low-resource translation corpora in the SIGUL workshop.

2 papers at EACL on multilingual transfer & diffusion models

In the EACL conference in March 2024, we are excited to present our paper on multilingual transfer for attribute-controlled translation. This work aims to customize pretrained massively multilingual translation models for attribute-controlled translation without relying on supervised data.

We are also proud that our thesis alumnus Yunus is presenting his work on diffusion models for machine translation at the student research workshop.

Invited Talk by Dr. Gerasimos Spanakis

Dr. Gerasimos (Jerry) Spanakis from Maastricht University's Law+Tech Lab will give an invited talk on "Find and free the law: How NLP can help access to legal resources". The talk will take place on 26 January from 2:00 to 3:00 in Bldg. 50.28, Seminar Room 1. You are all welcome to join!

EMNLP 2023 Demo Paper on Simultaneous Speech Translation

In the EMNLP conference in December 2023, we are excited to present our joint work with the Interactive Systems Lab on low-latency simultaneous speech translation! The work describes approaches to evaluate low-latency speech translation systems under realistic conditions, for instance our KIT Lecture Translator. See our paper for details! 

Paper in Machine Translation Summit: Perturbation-Based Quality Estimation

Quality estimation is the task of predicting the quality of machine translation outputs without relying on any gold translation references. We propose an explainable, unsupervised word-level quality estimation method for blackbox machine translation. It can evaluate any type of blackbox MT systems, including the currently prominent large language models (LLMs) with opaque internal processes. See the paper (link) for details! 

Looking for a new colleague!

We are looking for a PhD candidate (Akademische/r Mitarbeiter/in; all genders) in the field of natural language processing (large language models, multimodal language processing). Check out this link for details!

WMT Publication: Can we learn an artificial language?

The cornerstone of multilingual neural translation is shared representations across languages. In this work, we discretize the encoder output latent space of multilingual models by assigning encoder states to entries in a codebook, which in effect represents source sentences in a new artificial language (Link). Join the presentation on Wednesday, 07.12.2022 at 14:20 GST (11:20 CET) at the Seventh Conference on Machine Translation (WMT 2022).

Pre-trained Speech Translation
NeurIPS workshop paper: Efficient Speech Translation with Pre-trained Models

Pre-trained models are a promising approach to efficiently build speech translation models for many different tasks. Zhaolin Li showed how this models can be used using limited data and computation resources (Link). Join his presentation on Friday, 02.12.2022 between 7:30pm - 8:30pm CET at the Workshop Second Workshop on Efficient Natural Language and Speech Processing (ENLSP-II).


The "AI for Language Technologies" was found on 01.03.2022. We are looking foward to exciting reseearch and teaching at KIT.
