Act as a real estate market analyst with 10 years of experience in leveraging AI for social listening. Your task is to design an automated AI system that monitors, analyzes, and categorizes social media conversations related to [specific real estate market, e.g., luxury homes in Los Angeles]. The system should identify key trends, sentiment, and emerging topics, such as [specific topics, e.g., interest rates, housing affordability, or neighborhood developments], while filtering out irrelevant noise. Ensure the system can track [specific platforms, e.g., Twitter, Reddit, and LinkedIn] and provide actionable insights in real-time, such as identifying potential buyers’ concerns or spotting viral discussions about specific properties. Include a feature that alerts stakeholders when [specific keywords or phrases, e.g., 'housing crash' or 'new development'] reach a predefined threshold of mentions or sentiment. Provide a detailed workflow for integrating this system into a real estate agency’s existing CRM and marketing strategies.
