摘要:
Data from a click log may be used to generate training data for a search engine. User click behavior and user post-click behavior may be used to assess the relevance of a page to a query. Labels for training data may be generated based on data from the click log. The labels may pertain to the relevance of a page to a query. For example, user post-click behavior that may be examined includes the amount of time that a user remains on a target page when a user clicks one of the search results.

Disclosed are a system and a method for detecting a multi-view human face. The system comprises an input device configured to input image data; a hybrid classifier including a non-human-face rejection classifier configured to roughly detect non-human-face image data and plural angle tag classifiers configured to add an angle tag into the image data having a human face; and plural cascade angle classifiers. Each of the plural cascade angle classifiers corresponds to a human face angle. One of the plural cascade angle classifiers receives the image data with the angle tag output from the corresponding angle tag classifier, and further detects whether the received image data with the angle tag includes the human face.

The present invention relates to a method of changing between a plurality N of distinct services, e.g. television channels, receivable on a receiving unit, such as a mobile phone/cellular phone, a personal digital assistant (PDA), a handheld television unit, or similar devices. The receiving unit is adapted to receive the plurality of services in a time slicing mode with services being arranged in a certain time slice sequence. The receiving unit is capable of receiving a first service (S1). When “zapping” from the first service to a second service, the second service (S4) being chosen is the currently next service in time within the time slice sequence so as to minimize the time (t2) between service changes. Thereby, a fast method of changing between services is provided in a simplified manner, the speed of change reaching the theoretical maximum when using time slicing.

The present disclosure relates to a device comprising a mono-crystalline substrate, the mono-crystalline substrate having at least one recessed region which exposes predetermined crystallographic planes of the mono-crystalline substrate, the at least one recessed region further having a recess width and comprising a filling material and an embedded nanochannel, wherein the width, the shape, and the depth of the embedded nanochannel is determined by the recess width of the at least one recessed region and by the growth rate of the growth front of the filling material in a direction perpendicular to the exposed predetermined crystallographic planes. The present disclosure is also related to a method for manufacturing a nanochannel device.

The invention provides the use of silicon particles as redox catalyst, an electrochemical device and method thereof. As electrocatalyst, the silicon particles catalyze a redox reaction such as oxidization of the redox reactant such as renewable fuels e.g. methanol, ethanol and glucose. The device such as a fuel cell comprises a redox reactant and a catalytic composition comprising silicon nanoparticles. The silicon particles catalyze the redox reaction on an electrode such as anode in the device. In preferred embodiments, the electrocatalysis is dramatically improved under low illuminance such as in darkness. The invention can be widely used in applications related to for example a fuel cell, a sensor, an electrochemical reactor, and a memory.

The automatic search intent mining technique described herein pertains to a technique for mining search intent from a group of queries. The automatic search intent mining technique described herein automatically mines search intents from a group of queries. The technique leverages knowledge of query log data in order to determine search intent. The automatic search intent mining technique, in one embodiment, utilizes three kinds of information sources: Web page content, Web page structure and search engine query log data to mine intents for a group of queries. In one embodiment of the technique, the three data sources are used separately to mine candidate search intents for each of the three sources. The candidate search intents extracted from each of the three sources are then integrated to form the final search intents.

A high CRI white light emitting device comprises: a blue solid state light emitter (LED) operable to generate blue light; a phosphor material operable to absorb a portion of the blue light and to emit green/yellow light and a red solid state light emitter (LED) operable to generate red light. The emission product of the device comprises the combined light generated by the blue and red LEDs and green/yellow light generated by the phosphor material and appears white in color. The device further comprises a drive circuit operable to compensate for variation in the ratio (relative contribution) of red to blue light in the emission product such as to ensure that said variation is less than 20% over an operating temperature range of at least 25° C. The drive circuit can reduce variation in the CRI and CCT of the device's emission product over the operating temperature range.

A computer-readable storage medium having stored thereon computer-executable instructions which, when executed by a computer, cause the computer to implement an opinion search engine. The instructions to implement an opinion search engine cause the computer to collect opinion data about one or more objects from the Internet, extract metadata about the opinion data from the opinion data, remove duplicate metadata from the metadata to generate a resulting metadata, categorize the resulting metadata for similar objects according to one or more taxonomies from one or more websites on the Internet and rank the similar objects based on the categorized metadata.
