Inaccurate and Inefficient Manual Document Review Hindered by Scalability & Hidden Insights


Provenio needed a solution to

  • Automate anomaly detection: Accelerate review speed and reduce reliance on manual labor.
  • Improve accuracy: Minimize human error and ensure consistent anomaly identification.
  • Scale efficiently: Handle massive document volumes without compromising review quality.
  • Uncover hidden insights: Extract valuable patterns and trends for informed decision-making.

Enkefalos Technologies' Solution

LLM Model Building and Deployment:

  1. Data Acquisition and Preprocessing: We collaborated with Provenio to curate a substantial dataset of relevant documents, ensuring quality and diversity for model training.
  2. Model Selection and Pre-training: We chose a pre-trained LLM model suitable for anomaly detection and fine-tuned it on Provenio’s specific document domain and criteria.
  3. Customization and Training: We trained the LLM on the prepared dataset, focusing on identifying anomalies based on deviations in formatting, language patterns, and specific content criteria.
  4. Testing and Refinement: We rigorously tested the model’s performance, adjusting and retraining to optimize accuracy and reliability.
  5. Deployment and Integration: We seamlessly integrated the LLM model into the document management system, ensuring smooth data flow and efficient processing.

Human-in-the-Loop Web Application:

  1. Design and Development: We built a user-friendly web application for human analysts to review documents flagged by the LLM.
  2. Context and Highlighting: The app provided comprehensive context for each document and visually highlighted potential anomalies identified by the LLM.
  3. Confirmation and Refinement: Analysts could confirm the LLM’s findings, provide feedback, or refine the analysis for continuous improvement.
  4. Seamless Integration: The web app seamlessly integrates with the LLM model and document management system, ensuring a smooth review workflow.

Improved Document Review Process:

By combining the fine-tuned LLM model with the HITL web application achieved:

  • Faster Reviews: The LLM handled initial screening, significantly reducing human review time and workload.
  • Enhanced Accuracy: Consistent anomaly detection by the LLM minimized human error and improved overall accuracy.
  • Scalability: The automated system efficiently handled large document volumes, ensuring timely processing and analysis.

Deeper Insights: The LLM uncovered hidden patterns and trends, providing valuable data for informed decision-making.
