Highlights Legend: character emotion relationship

class: relationship

attributes: {type: romantic longing, character_1: Lady Juliet, character_2: Romeo}

Lady Juliet gazed longingly at the stars, her heart aching for Romeo

Entity 3/3 | Pos [42-68]

Note on LLM Knowledge Utilization: This example demonstrates extractions that stay close to the text evidence - extracting "longing" for Lady Juliet's emotional state and identifying "yearning" from "gazed longingly at the stars." The task could be modified to generate attributes that draw more heavily from the LLM's world knowledge (e.g., adding "identity": "Capulet family daughter" or "literary_context": "tragic heroine"). The balance between text-evidence and knowledge-inference is controlled by your prompt instructions and example attributes.

This demo showcases our long document summarization and structured data extraction capabilities. The highlighted parts in the video are the key entities identified by our AI, such as contract values, effective dates, and company names. This drastically simplifies data organization.
