Large Language Models (LLMs) have amazed us with their ability to generate human-quality text, translate languages, and answer complex questions. But what happens when you need them to tackle something outside their general knowledge base – like predicting the properties of a protein or translating a highly structured technical document? That's where tag-based prompting comes in.
Now imagine being able to give an LLM specific instructions and context, like adding new words to its vocabulary, to help it understand and excel in specialized domains. Tag-based prompting does just that. It allows users to inject domain-specific or task-specific information directly into the input, empowering LLMs to:
- Decipher complex scientific language and notations: From understanding protein sequences to processing chemical formulas, tag-based prompting unlocks the potential of LLMs for scientific discovery.
- Navigate highly structured documents: Preserve the integrity of markup tags during translation, ensuring accuracy and consistency in technical documents.
- Perform tasks it hasn't explicitly learned: By cleverly combining domain and function tags, you can guide LLMs to perform new and unseen tasks – like predicting the synergy between two drugs, a task with real-world implications in drug discovery research.
Essentially, tag-based prompting acts as a bridge between the vast general knowledge of LLMs and the nuanced needs of specialized tasks. It offers a level of control and adaptability that traditional prompting methods lack, allowing us to truly harness the power of LLMs for a wider range of applications.
How does tag based prompting work?
Tag-based prompting is a technique for adapting Large Language Models (LLMs) to perform specialized tasks by incorporating extra information into the input. This extra information is encoded as "tags", much like adding new words to the LLM's vocabulary. The main goal of tag-based prompting is to enhance the LLM's ability to understand and handle tasks that fall outside its initial training domain. It's especially useful for tasks involving specialised or technical domains that use language not extensively represented in the LLM's training data, tasks involving non-linguistic data, and structured document translation. At it's core, it works by adding two types of tags:
● Domain tags: These tags signal the start of specialized data in the input and provide general information about the domain of the task. Examples include tags for languages like French or domains like “protein sequence.” They act as context switchers, enabling the LLM to quickly adapt to different domains.
● Function tags: These tags encode specific instructions for the task that the LLM needs to perform. For example, a function tag might signal "translation" or "binding affinity prediction." Essentially, these tags tell the LLM what to do with the input data it's given.
Function tags: Typically placed at the end of the input sequence so they can attend to both the specialized data and the domain tags.
Advantages of Tag-Based Prompting
- Improved Performance: By providing targeted domain and task information, tags can enhance the LLM's ability to process specialized information, leading to improved accuracy and efficiency.
- Zero-Shot Generalization: Tag-based prompting can enable LLMs to perform tasks they haven't been explicitly trained on by combining domain and function tags in novel ways. This is possible due to the modular design of tag-based prompting.
- Modularity and Reusability: Separating domain and function tags makes them highly reusable and adaptable. New tags can be added incrementally, and existing tags can be combined to handle new tasks and domains.
- Fine-grained Control: Tags offer a more precise and granular level of control over the LLM's behaviour compared to traditional prompting methods. This allows for finer adjustments to the model's output and facilitates better handling of specific tasks.

Conclusion
LLMs are still sensitive to how prompts are formulated, even when using tag-based prompting. Carefully designing and testing the tags are essential to ensure optimal performance. Overall, tag-based prompting offers a promising approach to enhance the capabilities of LLMs and make them more effective in tackling specialized tasks and creating prompt templates for use in specific domains.
