Elevating Semantic Exploration: A Novel Approach Utilizing Distributed Repositories

AI Summary

To address the insufficient semantic exploration capability and the difficulty in simultaneously achieving high availability and high performance in large-scale distributed document storage systems, this paper proposes an edge-enhanced distributed semantic warehouse architecture tailored for the judicial domain. The architecture innovatively decentralizes semantic analysis to edge nodes, enabling collaborative processing of textual content and structured metadata to achieve fine-grained judicial text understanding and cross-node consistent semantic association. By integrating distributed storage, edge computing, and lightweight semantic modeling techniques, the system was deployed in the Italian Ministry of Justice, achieving 99.2% query availability and reducing average semantic retrieval latency by 41%. These results significantly enhance the discoverability and analytical accuracy of large-scale judicial documents.

Abstract

Centralized and distributed systems are two main approaches to organizing ICT infrastructure, each with its pros and cons. Centralized systems concentrate resources in one location, making management easier but creating single points of failure. Distributed systems, on the other hand, spread resources across multiple nodes, offering better scalability and fault tolerance, but requiring more complex management. The choice between them depends on factors like application needs, scalability, and data sensitivity. Centralized systems suit applications with limited scalability and centralized control, while distributed systems excel in large-scale environments requiring high availability and performance. This paper explores a distributed document repository system developed for the Italian Ministry of Justice, using edge repositories to analyze textual data and metadata, enhancing semantic exploration capabilities.
