Design Comprehensive Recommendation System for Spokeo Features
Design an End-to-End Recommendation System for Spokeo
You are tasked with designing a comprehensive, end-to-end recommendation system for Spokeo, a people-search platform. The primary goal is to enhance user experience by helping them find relevant profiles and related searches more quickly and safely.
Core Objectives
The system should aim to:
- Improve relevance: Ensure users find the right person or information.
- Increase efficiency: Reduce the need for users to reformulate searches.
- Ensure safety: Actively avoid harmful or sensitive suggestions.
Recommendation Surfaces and Targets
The system will primarily serve recommendations on:
- Search results pages.
- Profile detail pages.
Target recommendations include:
- "Profiles you might be looking for"
- "Related searches"
Design Deliverables
Your end-to-end design must cover the following critical components:
- Data Collection and Pipeline: Detail how data will be collected and processed, including both batch and streaming approaches.
- Feature Engineering: Describe the types of features you would create for the recommendation models.
- Model Selection: Propose suitable models for both candidate generation and ranking stages.
- Evaluation Metrics: Define both offline and online metrics to assess system performance.
- Real-time Serving Architecture: Outline the architecture for serving recommendations in real-time.
- A/B Testing and Experimentation Plan: Describe how you would set up and manage A/B tests and experimentation.
Additionally, your design must explicitly address strategies for handling cold-start users and items.
