[0002] The present application relates to systems and methods for generating multi-document summaries. Background technique

[0003] Multi-document summarization is the process of producing general or topic-focused summaries by reducing the document size while maintaining the main features of the original document. Since one cause of the data overload problem is that many documents share the same or similar topics, automatic multi-document summarization has gained much attention in recent years. The explosion of documentation on the Internet has fueled the need for generalization applications. For example, the generation of informative snippets in WEB search can help users further explore the snippets, and in question / answer systems, it is often necessary to provide the information queried...
