摘要 提供了一种旨在提高IE系统可移植性的事件IE模式的获取方法——IEPAM。使用IEPAM方法进行关于飞行事故事件IE模式获取的试验表明:该法能大大减少模式获取过程中用户的工作量并降低对他们的技能要求,所获取模式的质量也相当不错,从而提高了采用该法所建IE系统的可移植性。 This dissertation provides a pattern automatic acqnisition mechanism called IEPAM. The experiment using IEPAM indicates that this mechanism can largely decrease the labor and the skill requirement to the user during the pattern acquisition process and the patterns acquired through IEPAM are well enough to guide the factual event IE.
