会话系统可以分为两种类型。任务型和非任务型。最近对后者的研究主要集中在如何使用户在不感到无聊或疲劳的情况下继续对话。一些研究提出了多种方法来丰富词语或句子的表达形式。其他人则致力于主题联想。这两种解决方案都试图保持对话的趣味性，以便用户愿意继续与计算机对话。讨论了话题提供的意义，给出了一种自由会话系统中话题提供和控制的方法。具体地说，该系统根据用户的兴趣自动从Web中提取主题，并通过向用户提供虚构的主题来保持会话的继续。此外，系统不断检测用户可能对当前主题失去兴趣的时机，然后将主题更改为从主题网站获得的另一个主题。实验和问卷调查表明，我们的方法是有效的。
Conversation systems can be divided into two types. Task-oriented ones and non-task-oriented ones. Most recent researches on the latter one have focused on how to make the user continue the conversation without getting bored or tired. Some studies propose several ways to enrich the expressive forms of words or sentences. Others make efforts on topic association. Both solutions try to preserve the conversation interesting so that the user would like to continue talking with the computer. In this paper, we talk about the significance of providing topics, and give an approach to provide and control topics for a free conversation system. Specifically, the system extracts topics from the Web according to the user's interest automatically, and keeps the conversation going on by providing the fabricated topics to the user. Also the system constantly detects the timing when the user might have lost interests in the current topic, and then changes the topic to another one obtained from a topic website. Experiments and questionnaires show that our method works well.
