In order to measure and maintain semantic consistency in generated text, you can follow the strategies below:
- Use Similarity Metrics: You can compare embeddings of successive sentences or paragraphs using cosine similarity to ensure coherence.
- Reinforcement Learning: You can also fine-tune your model with reinforcement learning using rewards for consistency.
- Prompt Engineering: You can provide structured prompts emphasizing coherence.
Here is the code snippet showing how it is done:

In the above code, If similarity scores drop below a threshold, flag or regenerate the content to maintain coherence.
Hence, using these strategies, you can measure and maintain semantic consistency in generated text.
