    • A positron emission tomography method and a device with application adaptability. The method includes: 1. scanning a tested object initially for obtaining initial activity information of the tested object; 2. programming and adjusting a detector module based on the result of the initial scan so as to obtain a new system structure, and rapidly calibrating the new system structure; 3. performing a scan with the new system structure for obtaining activity information of the tested object; 4. analyzing the activity information of the tested object obtained at step 3. If quality of the activity information can satisfy requirements of the application, the scan is finished; otherwise programming and adjusting the detector module is repeated, rapid calibration is performed, and the activity information of the tested object is obtained again with the new system structure until the activity information satisfies requirements of the application. The device includes a detector module (1), a detector control module (2), an image reconstruction module (3) and a detector programming module (4).
    • 正电子发射断层摄影方法和具有应用适应性的装置。 该方法包括:1.最初扫描被测对象以获得被测对象的初始活动信息; 2.基于初始扫描的结果对检测器模块进行编程和调整,以获得新的系统结构,并快速校准新的系统结构; 3.使用新的系统结构执行扫描以获得被测对象的活动信息; 4.分析在步骤3中获得的测试对象的活动信息。如果活动信息的质量满足应用要求,则扫描结束; 否则重复编程和调整检测器模块,执行快速校准,并且用新的系统结构再次获得测试对象的活动信息,直到活动信息满足应用要求。 该装置包括检测器模块(1),检测器控制模块(2),图像重建模块(3)和检测器编程模块(4)。

    • One or more techniques and/or systems are disclosed for creating an expanded or improved lexicon for use in search-based semantic tagging. A set of first documents can be identified using a set of first lexicon elements as queries, and one or more first document patterns can be extracted from the set of first documents. The document patterns can be used to find one or more second documents in a query log that comprise the document patterns, which are associated with query terms used to return the second documents. The query terms for the second documents can be extracted and used to expand the lexicon. Elements within the lexicon may be weighted based upon relevance to different query domains, for example.
    • 公开了一种或多种技术和/或系统,用于创建用于基于搜索的语义标签中的扩展或改进的词典。 可以使用一组第一词典元素作为查询来识别一组第一文档,并且可以从该组第一文档中提取一个或多个第一文档图案。 文档模式可用于在查询日志中找到构成文档模式的一个或多个第二文档,这些文档模式与用于返回第二个文档的查询术语相关联。 可以提取和使用第二个文档的查询条款来扩展词典。 例如,词法中的元素可以基于与不同查询域的相关性来加权。
