Learning Physical Common Sense as Knowledge Graph Completion via BERT Data Augmentation and Constrained Tucker Factorization (2020.emnlp-main)
Copied to clipboard
| Challenge: | Physical commonsense learning is an essential part of human-robot interaction . existing methods of learning physical commons sense suffer from generalization . |
| Approach: | They propose to use physical commonsense learning as a knowledge graph completion problem to better use latent relationships among training samples. |
| Outcome: | The proposed method outperforms existing methods in the human-robot interaction problem. |
Text Emotion Distribution Learning from Small Sample: A Meta-Learning Approach (D19-1)
Copied to clipboard
| Challenge: | Existing methods for text emotion distribution learning require a large amount of training data, which is difficult to obtain due to inconsistent perception of fine-grained emotion intensity. |
| Approach: | They propose a meta-learning approach to learn text emotion distributions from a small sample using tensor decomposition to capture contextual semantic similarity. |
| Outcome: | The proposed method outperforms state-of-the-art methods on a widely used EDL dataset. |
Embedding Lexical Features via Tensor Decomposition for Small Sample Humor Recognition (D19-1)
Copied to clipboard
| Challenge: | Existing methods for humor recognition require a large amount of training data with labels to learn effective features. |
| Approach: | They propose a tensor embedding method that can extract lexical humor features for continuous humor recognition by using word-word co-occurrence to encode contextual content of documents, and then decompose the tenor to get corresponding vector representations. |
| Outcome: | The proposed method achieves a distance of 0.887 on a global humor ranking task, comparable to the top performing systems from SemEval 2017 Task 6B, but without the need for any external training corpus. |
Educational Question Generation of Children Storybooks via Question Type Distribution Learning and Event-centric Summarization (2022.acl-long)
Copied to clipboard
| Challenge: | Existing methods to generate educational questions of fairytales or storybooks are difficult to implement due to adults lacking the skills or time to integrate such interactive opportunities. |
| Approach: | They propose a question generation method that first learns the question type distribution of an input story paragraph, and then summarizes salient events which can be used to generate high-cognitive-demand questions. |
| Outcome: | The proposed method performs well on automatic and human evaluation metrics on a newly proposed educational question-answering dataset FairytaleQA. |
