摘要： One embodiment provides a system that detects sensitive passages. During operation, the system receives a document and disassembles the document into a plurality of passages. For a respective passage, the system performs a search through a non-sensitive-passage database to determine whether the passage is a known non-sensitive passage. If so, the system marks the passage as non-sensitive, and if not, the system determines whether the passage triggers a cut-and-paste attack detection. If so, the system forwards the passage to an administrator and allows the administrator to determine whether the passage is non-sensitive and, further, to add the passage to the non-sensitive-passage database responsive to the administrator determining the passage to be non-sensitive.

摘要： One embodiment of the present invention provides a system for automatically authenticating a user. During operation, the system receives a user's request for authentication. The system then extracts information associated with the user from user-specific information stored in an enterprise computer. The extracted user information does not explicitly relate to a password. The system further generates one or more challenges based on the extracted user information, and receives the user's response to the challenges. Subsequently, the system compares the user's response to the extracted user information, and authenticates the user.

摘要： A system is provided to detect email spam. During operation, the system receives an email, extracts a set of keywords from the email body, and constructs a first search query based a keyword extracted from the email body. The system further constructs a second search query based on the keyword in the first query and one additional word which pertains to a known spam word or to the subject of the email. Next, the system receives a first number of hits and a second number of hits in response to the first and second search queries, respectively. The system then determines whether the email is spam based on the first number and the second number. The system can also perform Website filtering using inference detection which is based on search results received in response to search queries formulated with keywords extracted from Websites.

摘要： One embodiment of the present invention provides a system that detects inferences from documents. During operation, the system receives one or more documents and extracts a first set of knowledge relevant to the documents. The system further formulates one or more queries to one or more reference corpora based on the first set of knowledge. The system then extracts a second set of knowledge from results received in response to the queries. Additionally, the system produces a mapping relationship between at least one document and a piece of the second set of knowledge which is not within the first set of knowledge, the mapping relationship indicating an inference from the documents.

摘要： One embodiment of the present invention provides a system that facilitates filtering outbound content via inference detection. During operation, the system identifies content sent to a first address and extracts keywords from the identified content. The system then issues queries based on these keywords and extracts expected-content keywords from the hits returned in response to the queries. The system then searches the outbound content for occurrences of the expected-content keywords and produces a result which allows a user to determine whether the outbound content is proper. In a further embodiment, the system extracts keywords from a piece of outbound content, and issues queries based on these keywords. The system then extracts keywords from the hits, and present at least one keyword to a user, thereby allowing the user to determine whether the outbound content is proper.

摘要： A targeted advertising system performs context-based association mining using a publicly available corpus to identify a product or brand name that, under a given context, is associated with a product or brand being marketed. The system analyzes documents within the publicly available corpus that are associated with the given context, and identifies products or brand names that have a high association to the product or brand being marketed. The system can also analyze the publicly available corpus to determine contextual information which is correlated to two or more products or brand names. This contextual information includes a set of terms that facilitates filtering the publicly available corpus into an optimal set of documents that has a high association to a desired market category or demographic.
摘要翻译： 有针对性的广告系统使用公开可用的语料库来执行基于上下文的关联挖掘，以识别在给定上下文与正在上市的产品或品牌相关联的产品或品牌名称。 系统分析与给定上下文相关联的公开可用语料库中的文档，并且识别与被销售的产品或品牌具有高关联性的产品或品牌名称。 系统还可以分析公开的语料库，以确定与两个或多个产品或品牌名称相关的上下文信息。 该上下文信息包括一组术语，其有助于将公开可用的语料库过滤成与期望的市场类别或人口统计学高度关联的最佳文档集合。

摘要： One embodiment of the present invention provides a system that detects sensitive content in a document. In doing so, the system receives a document, identifies a set of terms in the document that are candidate sensitive terms, and generates a combination of terms based on the identified terms that is associated with a semantic meaning. Next, the system performs searches through a corpus based on the combination of terms and determines hit counts returned for each term in the combination and for the combination. The system then determines whether the combination of terms is sensitive based on the hit count for the combination and the hit counts for the individual terms in the combination, and generates a result that indicates portions of the document which contain sensitive combinations.
