| 摘要: |
| 应用话题检测技术中的聚类思想,分析了动态多文档文摘时间特性.利用时间信息的阈值变化得到不同的多文档聚类结果,进而生成基于动态网页信息数据流的多文档文摘.针对不同阈值的多文档文摘比较,了解时间信息在动态的多文档文摘中的重要性.实验证明在TDT的话题检测技术中,可通过调整α值的方法来平衡TDT的输出结果,进而生成质量更好的动态多文档文摘。 |

| Abstract: |
| In this paper time characteristics of dynamic multi-documents summarization has been analyzed by the clustering idea in topic detection technology.From the change of time information threshold value,differ-ent multi-document clustering and multi-documents summarization for the dynamic Web information data stream can be generated.By compared with different threshold values,the importance of time information in a dynamic multi-document summarization is understanded.Experimental result means that you can counterpoise the output of TDT by adjusting α value and generate better quality dynamic multi-document summarization. |
| Key words: topic detection temporal properties dynamic threshold multi-document summarization |
