    • A method, computer-usable medium, and a computer system for searching for webpages are disclosed. Embodiments of the present invention provide a convenient and efficient mechanism for filtering results from a keyword search using semantic keys and semantic sub-keys, thereby enabling an increased number of irrelevant results to be filtered from a keyword search. The search query may be parsed to determine the focus of the query, where the focus may be used determine at least one semantic key for the search query. Each semantic key may be associated with at least one semantic sub-key, where the semantic keys and/or the semantic sub-keys may be used to filter the results of the keyword search. As such, broader keyword searches may be performed to include a larger number of relevant results, where the filtering mechanisms of the present invention may then filter an increased number of irrelevant results.
    • 公开了一种用于搜索网页的方法,计算机可用介质和计算机系统。 本发明的实施例提供了一种用于使用语义密钥和语义子密钥过滤关键字搜索的结果的便利和有效的机制,从而使得能够从关键字搜索中过滤不必要的结果的数量增加。 可以解析搜索查询以确定查询的焦点,其中可以使用焦点来确定用于搜索查询的至少一个语义密钥。 每个语义密钥可以与至少一个语义子密钥相关联,其中语义密钥和/或语义子密钥可以用于过滤关键字搜索的结果。 因此,可以执行更广泛的关键字搜索以包括更多数量的相关结果,其中本发明的过滤机制可以过滤不必要的结果的增加数量。

    • A computer-implemented method, computer-readable medium and system for scoring a text are disclosed. Themes within one or more texts may be determined and used to score each text, where an overall score for each text may indicate a respective importance and/or value of each text. The score for each text may be determined based upon a number of themes, type of themes, frequency of theme elements associated with the themes, distribution of theme elements associated with the themes, location of themes in the text, some combination thereof, etc. In this manner, the importance or value of one or more texts may be determined more accurately using information within each text with reduced reliance upon external information. Additionally, more relevant search results can be returned to a user by using internal information to perform ranking operations and/or filtering operations associated with a search.
    • 公开了一种用于评分文本的计算机实现的方法,计算机可读介质和系统。 可以确定一个或多个文本内的主题并用于对每个文本进行评分,其中每个文本的总分可以指示每个文本的相应重要性和/或值。 每个文本的分数可以基于主题数量,主题类型,与主题相关联的主题元素的频率,与主题相关联的主题元素的分布,文本中的主题的位置,其某种组合等来确定。 以这种方式,可以使用每个文本内的信息更准确地确定一个或多个文本的重要性或价值,同时减少对外部信息的依赖。 此外,通过使用内部信息来执行与搜索相关联的排序操作和/或过滤操作,可以向用户返回更相关的搜索结果。

    • A comparator circuit for providing hysteresis comprises first and second differentially coupled transistors. The first of the differentially coupled transistors provides drain current to first and second load transistors. The second of the differentially coupled transistors provides drain current to third and fourth load transistors. In one example embodiment, the drain of the first of the differentially coupled transistors also drives the gate of the first and third load transistors, while the drain of the second of the differentially coupled transistors drives the gate of the second and fourth transistors.
    • 用于提供滞后的比较器电路包括第一和第二差分耦合晶体管。 第一个差分耦合晶体管为第一和第二负载晶体管提供漏极电流。 差分耦合晶体管中的第二个为第三和第四负载晶体管提供漏极电流。 在一个示例实施例中,第一差分耦合晶体管的漏极也驱动第一和第三负载晶体管的栅极,而第二个差分耦合晶体管的漏极驱动第二和第四晶体管的栅极。

    • In a current switch, a bias generation circuit electrically connected to a high voltage power supply generates a bias current. The bias current is mirrored by a current mirror containing a first plurality of transistors to a first one of a second plurality of transistors. The first one of the second plurality of transistors amplifies the mirrored bias current and transmits the amplified bias current to a second one of the second plurality of transistors. The second one of the second plurality of transistors sinks the amplified bias current into a node shared by an internal reference voltage, thereby putting the node in a first logic state. A third one of the second plurality of transistors receives the amplified bias current from the second one of the second plurality of transistors and sinks the amplified bias current into a node shared by a gate of a high voltage p-type transistor, thereby putting the node in the first logic state. Putting both nodes in the first logic state turns off the high voltage transistor.
