Large Language Models for Expansion of Spoken Language Understanding Systems to New Languages
Model description
This model is a fine-tuned version of the pre-trained model James-WYang/BigTranslate, specifically adjusted to handle the slot translation task. The fine-tuning process and the specific model adjustments are based on methodologies described in our recent publication https://arxiv.org/pdf/2404.02588.pdf. This model is designed to translate sentences while maintaining the integrity of annotated NLU (Natural Language Understanding) slots, which are marked with simple HTML-like tags.
The input to the model should be a sentence where all NLU slots are annotated with HTML-like tags consisting of consecutive alphabetical letters (e.g., <a>, <b>, <c>). The model outputs the translated sentence preserving these annotations.
Example: "Set the temperature on my <a>thermostat<a> to <b>29 degrees<b>."
