Parliamentary act metadata extraction and summary generator

Use case ID: 043

Author: Senate of Italy

Date: 18 June 2024

Objective:

Automatically extract metadata and compile summary sheets or tables from a collection of parliamentary acts, enhancing the efficiency and accuracy of legislative document analysis and research.

Actors:

• Parliamentary staff members
• MPs
• Legislative drafters
• Artificial intelligence (AI) development and support team

Prerequisites:

• Access to a comprehensive dataset of parliamentary acts
• Predefined criteria for metadata extraction (e.g. references to implementing provisions or expenditure forecasts)
• Pre-trained language models specialized in legal text analysis
• Integration with parliamentary document management systems

Scenario:

1. A parliamentary staff member uploads a set of parliamentary acts to the system.
2. The staff member specifies the criteria for metadata extraction, such as references to implementing provisions, expenditure forecasts or other key elements.
3. The AI system processes the documents using natural language processing (NLP) techniques.
4. The AI system identifies and extracts the relevant metadata from each document.
5. The extracted metadata are used to automatically compile summary sheets or tables, with the information organized in a structured and accessible format.
6. The staff member reviews the compiled summaries for accuracy and completeness.
7. MPs and other authorized users can search and retrieve the summary sheets, facilitating quicker access to relevant information.

Alternate flows:

• If the uploaded document format is not supported, the system prompts the user to convert the documents into a supported format.

Expected results:

• Accuracy and speed in extracting and compiling metadata from legislative texts are enhanced.
• Searchability and retrieval of critical information within documents are improved.
• Manual workload for staff members is reduced.

Potential challenges:

• Ensuring the AI system accurately identifies and extracts relevant metadata in complex legal language
• Handling variations and updates in legal terminologies and references
• Integrating the AI system seamlessly with existing document management systems

Data requirements:

• Historical parliamentary acts for model training
• Annotations of relevant metadata for supervised learning
• Continual updates of legal texts and terminologies to refine the model

Integrations with other systems:

• Parliamentary document management system
• User authentication and access control systems

Success metrics:

• Accuracy rate of metadata extraction
• Reduction in time taken for researchers to compile summary sheets
• Increase in the number of successful searches for summarized metadata
• User satisfaction scores from parliamentary staff and researchers
