Identifying Prohibited Firearm Listings

Requirements Clarification & Assessment

1. Clarifying Questions:

   • Data Availability: Do we have a labeled dataset of firearm listings? If not, how do we plan to obtain or create one?
   • Listing Details: Will the listings include both text descriptions and images?
   • Prohibited Items List: Is there a predefined list of keywords or descriptions that are strictly prohibited?
   • Current Process: What is the current process for identifying and handling firearm listings?
   • System Integration: How is the model expected to integrate into the existing system? Will it automatically disable listings or notify customer service?
   • Real-time vs. Batch Processing: Is the system required to perform real-time detection, or can it operate on a batch processing schedule?

2. Assessing Requirements:

   • Data Sources:
     • Text data from listing titles and descriptions.
     • Image data from listing photos.
     • User metadata, such as profile information and historical activity.
   • Functional Requirements:
     • Must accurately identify listings involving firearms.
     • Minimize false negatives to prevent prohibited sales.
     • Balance false positives to avoid unnecessary disruption to legitimate sellers.
   • Non-functional Requirements:
     • Scalability to handle large volumes of listings.
     • Compliance with legal and regulatory standards.
     • Seamless integration with existing marketplace infrastructure.
