2. How to use big data to analyze hot spots?

1.Data collection: Capture multi-platform data through crawler tools (such as Scrapy) or APIs (such as Twitter API) to ensure breadth of coverage and timeliness.

2.Data cleaning: Use Python (Pandas library) or ETL tools (such as Informatica) to process noisy data, such as deduplication and missing value filling.

3.data analysis: Mining trends through natural language processing (NLP) or machine learning models such as LSTM. For example, a sentiment analysis was performed on the "iPhone 15" topic and it was found that 35% of users' negative feedback on battery life accounted for 35%.

3. Challenges and Solutions of Big Data Applications

Challenge 1: Data silosThe data formats of different platforms are not uniform, and a standardized data warehouse (such as Hadoop HDFS) needs to be established.

Challenge 2: Real-time requirementsStream processing frameworks (such as Apache Kafka) can achieve second-level response and are suitable for public opinion monitoring.

4. Future Outlook

With the popularization of AI technology, big data analysis will become more intelligent. For example, combine GPT-4 to automatically generate hotspot reports, or mine topic correlations through graph database (Neo4j).

Through structured data and multi-dimensional analysis, "big data" is no longer a problem, but the core engine driving business growth.
