Map-Reduce
Description
The map-reduce chain iterates over a list of documents, generating individual outputs for each and then combining them into a final result. This approach is particularly useful for tasks requiring parallel document processing followed by aggregation.
Advantages:
- Parallel processing: Allows parallel execution on individual documents, improving efficiency and reducing processing time.
- Scalability: Handles large document collections by distributing the processing load.
- Enhanced information extraction: Generates specific information from each document, contributing to a comprehensive final result.
Disadvantages:
- Complexity in output aggregation: Requires careful handling to ensure coherency and meaningful synthesis.
- Potential redundancy: May generate redundant information, necessitating further post-processing.
Use Cases
- Multiple Document Summarization: Summarizes individual research papers, then merges them into a comprehensive summary capturing key information from the entire collection.
