Modeling Noisiness to Recognize Named Entities using Multitask Neural Networks on Social Media (N18-1)
Copied to clipboard
| Challenge: | Current approaches to Named Entity Recognition (NER) are effective in formal text, but they fail on informal text, where improper grammatical structures, spelling inconsistencies, and slang vocabulary prevail. |
| Approach: | They propose a multitask end-to-end bidirectional long short-term memory (BLSTM)-Conditional Random Field (CRF) network with two CRF classifiers and a feature extractor that transfers learning to a CRF for prediction. |
| Outcome: | The proposed models outperform the current state-of-the-art on the Workshop on Noisy User-generated Text 2017 dataset by 2.45% and 3.69%, establishing a more suitable approach for social media environments. |
Early Text Classification Using Multi-Resolution Concept Representations (N18-1)
Copied to clipboard
| Challenge: | e-communications have been misused by cyber-criminals, who hide in the depths of the web. |
| Approach: | They propose a document representation which allows us to generate multiple "views" of the analyzed text. |
| Outcome: | The proposed representation outperforms existing models in two tasks where anticipation is critical: sexual predator detection and depression detection. |
Detecting Depression in Social Media using Fine-Grained Emotions (N19-1)
Copied to clipboard
| Challenge: | Mental disorders affect millions of people around the world and depression is among the most common. |
| Approach: | They propose a representation of social media documents by a set of emotions generated by lexical resources and subword embeddings. |
| Outcome: | The proposed representation improves the results of the evaluation based on the core emotions and the state-of-the-art representations compared to the current methods. |
