摘要:

刑事调查主要依靠收集语音对话数据,以确定说话人并建立或丰富现有的犯罪网络。然后应用社会网络分析工具来识别网络中最核心的人物和不同的社区。我们介绍了两个候选数据集的犯罪会话数据,犯罪现场调查(CSI),电视节目,和ROXANNE模拟数据。我们还介绍了在刑事调查的背景下,对话的准确性的度量。通过基于先前交互的频率对候选说话人进行重新排序,我们在CSI数据上将说话人辨识基线提高了1.2%的绝对值(1.3%的相对值),并且将会话准确率提高了2.6%的绝对值(3.4%的相对值),并且在ROXANNE模拟数据上分别提高了1.1%的绝对值(1.2%的相对值)和2%的绝对值(2.5%的相对值)。

英文摘要:

Criminal investigations mostly rely on the collection of speech conversational data in order to identify speakers and build or enrich an existing criminal network. Social network analysis tools are then applied to identify the most central characters and the different communities within the network. We introduce two candidate datasets for criminal conversational data, Crime Scene Investigation (CSI), a television show, and the ROXANNE simulated data. We also introduce the metric of conversation accuracy in the context of criminal investigations. By re-ranking candidate speakers based on the frequency of previous interactions, we improve the speaker identification baseline by 1.2% absolute (1.3% relative), and the conversation accuracy by 2.6% absolute (3.4% relative) on CSI data, and by 1.1% absolute (1.2% relative), and 2% absolute (2.5% relative) respectively on the ROXANNE simulated data.
