Papers with OOV problem
Improving Slot Filling in Spoken Language Understanding with Joint Pointer and Attention (P18-2)
Copied to clipboard
| Challenge: | Experimental results show the effectiveness of our slot filling model at addressing the OOV problem. |
| Approach: | They propose a generative neural network model for slot filling based on a sequence-to-sequence model and a pointer network. |
| Outcome: | The proposed model is able to predict slot values on spoken language data. |
Improving Word Embeddings through Iterative Refinement of Word- and Character-level Models (2020.coling-main)
Copied to clipboard
| Challenge: | Embedding of rare and out-of-vocabulary words is an important open NLP problem . standard embedding models are not useful for recommending jobs to users with rare or unseen words . |
| Approach: | They propose to train a character-level neural network to reproduce word embeddings . they then use the model to assign vectors to any input string, including rare words . |
| Outcome: | The proposed method outperforms existing methods on word similarity data sets and can be applied to job title normalization in the e-recruitment domain. |
