Playing with Embeddings : Evaluating embeddings for Robot Language Learning through MUD Games

Anmol Gulati, Kumar Krishna Agrawal
2017 Proceedings of the 2nd Workshop on Evaluating Vector Space Representations for NLP  
In this paper, we study the suitability of using general purpose word-embeddings for language learning in robots.  ...  Based in a risk-reward setting, we review the effectiveness of the embeddings in navigating tasks in fantasy games, as an approximation to their performance on more complex scenarios, like language assisted  ...  In a similar spirit, MUD games provide a rich playground for define complex scenarios solely with textual descriptions.  ...

The Road to Know-Where: An Object-and-Room Informed Sequential BERT for Indoor Vision-Language Navigation [article]

Yuankai Qi, Zizheng Pan, Yicong Hong, Ming-Hsuan Yang, Anton van den Hengel, Qi Wu
2021 arXiv   pre-print
Our sequential BERT also enables the visual-textual clues to be interpreted in light of the temporal context, which is crucial to multi-round VLN tasks.  ...  Vision-and-Language Navigation (VLN) requires an agent to find a path to a remote location on the basis of natural-language instructions and a set of photo-realistic panoramas.  ...  However, most of them are designed for one-round decision tasks (e.g., VQA).  ...

A Semantic Case-Based Reasoning Framework for Text Categorization [chapter]

Valentina Ceausu, Sylvie Desprès
2007 Lecture Notes in Computer Science  
This paper presents a semantic case-based reasoning framework for text categorization. Text categorization is the task of classifying text documents under predefined categories.  ...  We propose a textual case-based reasoning approach (TCBR), which allows us to integrate both textual and domain knowledge aspects in order to carry out this categorization.  ...  Thus, methods, like in particular Information Retrieval, are not sufficient to create knowledge-rich case representations from text.  ...
