摘要： A method and an apparatus for named entity recognition, and a non-transitory computer-readable recording medium are provided. In the method, text elements are traversed according to a text span to obtain candidate entity words. Then, a class to which the candidate entity word belongs is recognized. The recognizing of the class includes generating a prompt template corresponding to the candidate entity word, and concatenating the text to be recognized and the prompt template to obtain a concatenated text; generating vector representations of the text elements in the concatenated text; generating the vector representation of the candidate entity word according to the vector representations of the text elements of each candidate entity word in the concatenated text, and the vector representation of the text element of the mask word; and classifying the vector representation of the candidate entity word to obtain the class of the candidate entity word.

摘要： A method and an apparatus for recognizing an intention, and a non-transitory computer-readable recording medium are provided. The method includes learning vectors of knowledge base elements in corpus samples, and converting the corpus samples into row vectors composed of the vectors of the knowledge base elements in a knowledge base; extracting feature vectors from respective pooling windows in the corpus samples by hierarchical pooling, determining weights positively correlated with similarities between texts within the respective pooling windows and the respective corpus samples, performing weighting on the extracted feature vectors to obtain feature vectors of the respective pooling windows, and obtaining feature vectors of the respective corpus samples composed of the feature vectors of the pooling windows; training a vector-based intention recognition classifier, based on the feature vectors of the corpus samples; and recognizing an intention in querying a corpus, using the trained intention recognition classifier.

摘要： The present disclosure provides a rotary wireless network card with double rotating shafts, which comprises a wireless network card body, an ultra-thin USB interface and a first rotating shaft, wherein at the top of the wireless network card body a opening is provided to accommodate the ultra-thin USB interface as withdrawn; the ultra-thin USB interface extends out of or returns back to the opening by rotating around the first rotating shaft; inside the wireless network card body a rotating shaft support is provided; a second rotating shaft in the opening is rotatably connected to the rotating shaft support; the second rotating shaft is accommodated outside the ultra-thin USB interface and connected to the ultra-thin USB interface; and when the second rotating shaft rotates in the opening, the ultra-thin USB interface and the first rotating shaft rotate in the opening along with the second rotating shaft. By designing a rotary head, the present disclosure frees a USB from the external connection with a cap or other objects that are easily lost or broken, and as the rotary shaft of the ultra-thin USB interface is smaller than common rotary shafts, the whole wireless network card is much shorter and narrower, causing no interference on the use of a neighboring interface.

摘要： A class D power amplifier (PA) is provided. The PA generally comprises a driver, output capacitor, a matching network, and a cancellation circuit. The driver has an input, an output, and a parasitic capacitance, and the input of the driver is configured to receive complementary first and second radio frequency (RF) signals, where there is a free-fly interval between consecutive pulses from the first and second RF signals. The output capacitor and cancellation circuit are each coupled to the output of the driver such that the cancellation circuit provides harmonic restoration at least during the free-fly interval, and the matching network is coupled to the output capacitor.

摘要： A hysteretic buck converter provides improved regulation control, in particular for buck converter standby operation. A comparison circuit compares the output voltage of the buck converter to a waveform that is generated from an indication of the output current of the converter, so that the turn-on time of the converter is advanced as the output current demand increases. The resulting action anticipates a reduction in output voltage due to the increased current, preventing an excursion of the output voltage below the ripple voltage minimum. The turn-off time of the converter is controlled by an upper threshold that limits the ripple voltage maximum. The output current indication may be a measurement of output current, or may be a dynamic value calculated from the input voltage and the output voltage waveform.

摘要： An indicator pin of an input/output controller is used to identifying whether a processor or a bridge is configured in a processor. When a predetermined voltage level of the indicator pin is confirmed, a base input/output system of the computer system renews a coherent/non-coherent HyperTransport link table. Then an initialization procedure is performed in accordance with the renewed coherent/non-coherent HyperTransport link table.

摘要： A computer system includes a bridge module plugged in a processor socket of a motherboard with multiple processors. The bridge module electrically connects two buses which have the same transmission protocol and connect to the socket. Thus, two processors or a processor and a chip set would communicate each other by the bridge module and the two buses without installing any processors or additional buses.
