摘要： Determining sensitive information and preventing the unauthorized or unintended dissemination of such information are disclosed. Terms are determined from documents associated with users in a network. Distributions among users and relative frequencies with which the terms are used are determined. Link strengths between users are calculated. Based on the distribution of the terms, the relative frequencies of use among the user profiles and link strengths between users conducting information transactions that include the terms, a sensitivity level for each term can be determined. To determine whether a particular information transaction with particular terms may be conducted between two users in the network, a combination of link strength between the users and sensitivity level of the terms with respect to the users or users' profiles are considered. If the information transaction includes terms that are unknown to one of the users, then a warning or alarm can be raised.

摘要： The power of analytical modeling is added to existing methods for specifying policies. Generally speaking, humans use their knowledge and experience to draft policies at a relatively high level. These policies then incorporate analytical models which provide the intelligence on how to most effectively apply the high-level policy to a particular situation. When a policy is invoked, the analytical model provides up-to-date intelligence at a level of completeness and refinement not possible with previous techniques. As a result, fewer policies need to be drafted, and those few need to be updated less frequently than in previous schemes. Rather than updating the policy itself, the analytical model is automatically updated whenever new data are fed into it. As the analytical model incorporates new observational data, it grows more powerful and thus automatically increases the effectiveness of the high-level policy.

摘要翻译：披露敏感信息的确定和防止未经授权或意外传播此类信息。术语由与网络中的用户相关联的文档确定。确定用户之间的分布和使用这些术语的相对频率。计算用户之间的链接强度。根据术语的分配，可以确定用户简档之间的相对使用频率和进行包括术语的信息交易的用户之间的链接强度，每个术语的灵敏度级别。为了确定是否可以在网络中的两个用户之间进行具体特定术语的特定信息交易，考虑用户之间的链路强度和相对于用户或用户简档的术语的灵敏度级别的组合。如果信息交易包含一个用户未知的条款，则可以提出警告或警报。

摘要翻译：分析建模的力量被添加到用于指定策略的现有方法中。一般来说，人类利用自己的知识和经验，在较高层次上制定政策。然后，这些政策纳入了分析模型，提供了如何最有效地将高级别政策应用于特定情况的情报。当调用策略时，分析模型将提供最新的智能水平，使之与以前的技术无法完成和完善。因此，需要起草较少的政策，少数需要比以前的计划更频繁地更新。而不是更新策略本身，分析模型会在每次新数据被输入时自动更新。由于分析模型结合了新的观测数据，其增长更强大，从而自动提高高层次政策的有效性。
