The attention-based representation enrichment mechanism proposed in the EnriCo framework can be extended to other structured prediction tasks by adapting the model architecture and training process to suit the specific requirements of the new task. Here are some ways this mechanism can be extended:
Task-specific Attention Heads: Introduce task-specific attention heads that focus on relevant parts of the input for the new task. By training these attention heads to capture task-specific information, the model can enrich its representations for improved performance.
Contextual Embeddings: Incorporate contextual embeddings that capture the relationships between different elements in the input. By enhancing the model's ability to understand context, it can generate more informative representations for structured prediction tasks.
Hierarchical Attention: Implement hierarchical attention mechanisms that allow the model to attend to different levels of granularity in the input data. This can help capture dependencies and patterns at multiple levels, enhancing the richness of the representations.
Multi-task Learning: Extend the model to handle multiple related tasks simultaneously, leveraging shared representations and attention mechanisms across tasks. This can lead to more comprehensive and enriched representations for structured prediction.
By incorporating these adaptations and modifications, the attention-based representation enrichment mechanism can be effectively applied to a wide range of structured prediction tasks beyond joint entity and relation extraction.
