A deployed strategy engine generates a virtual machine at each co-located server, which thus allows the co-located server to execute complex orders received from the end user. The end user may modify or delete the complex order at each co-located server at any time. Transit time latency issues are drastically reduced under this system and method. |

The first core instructs the second cores, presumed to be capable of immediately executing the decoding process or executing the decoding process next to a decoding process being currently executed, to execute the decoding process. The second cores are configured to be capable of simultaneously executing the decoding process on read images instructed by the first core at different timings. |

Automatic search method for a structural mode signal of a chipless RFID tag
The proposed invention discloses an automatic search method for a structural mode signal of a chipless RFID tag. A reference plane, a target to be tested, a reader antenna and a reader are set in space. The target to be tested is located within the reading range of the reader antenna. The distance difference between the tag and the reference plane, to the antenna, is measured by using the phenomenon of the backscattered signals of the tag and the reference plane interfering in space, to obtain the distance between the tag and the antenna. The time period for extracting the antenna mode of the tag may maximize the use of the antenna mode signal, thereby enhancing the accuracy of reading the tag. |

Automatic post-editing model for neural machine translation
Techniques are disclosed for training and/or utilizing an automatic post-editing model in correcting translation error(s) introduced by a neural machine translation model. The automatic post-editing model can be trained using automatically generated training instances. A training instance is automatically generated by processing text in a first language using a neural machine translation model to generate text in a second language. The text in the second language is processed using a neural machine translation model to generate training text in the first language. A training instance can include the text in the first language as well as the training text in the first language. |

Multi-scale model for semantic matching
A method for applying a trained machine learning model to answer a user query comprises receiving a query text from a user. A previously-trained discriminator is received, the previously-trained discriminator configured to output, for a pair of sentences, a match value indicating a quality of semantic match between the pair of sentences. For each candidate answer text of a plurality of candidate answer texts, the previously-trained discriminator is operated to output a candidate match value for the query text and the candidate answer text based on comparing a first hierarchy of representations of the query text at increasing degrees of semantic compression to a second hierarchy of representations of the candidate answer text at increasing degrees of semantic compression. An answer text is output that is associated with a highest candidate match value among candidate match values. |

Cognitively generating information from videos
In an approach for detecting key messages for a video, a processor builds a role model based on data from one or more data sources, with an identification feature of each role in a video. A processor samples a plurality of frames of the video. A processor identifies a key object presented in the plurality of frames. The key object is a role in the video. A processor recognizes a movement scenario associated with the role. A processor dynamically updates the role model based on the movement scenario. A processor identifies a role name based on the movement scenario. A processor generates a description script associated with the movement scenario for the role. A processor outputs the description script. |

Computer-implemented method and system for providing a review process of a document
A method for providing a review process of a document can include receiving, at a document server, the document to be reviewed from a first client; providing, by the document server, access to the document to be reviewed via a second client to start the review process for a user of the second client. During and/or after the review process, the document server can evaluate the quality of the review process and provide information on the evaluated quality to the first client so that the user of the first client can receive an indication of how the review process has occurred or is occurring and have an indication of the quality of that review that is being performed or was performed. Embodiments of a communication apparatus and system for providing information on a review process of a document can be configured to utilize embodiments of the method. |

Stratification of token types for domain-adaptable question answering systems
A method determines a relevancy of answers to questions based on token relevance in a system capable of answering questions. One or more processors receive a question that is composed of a set of tokens T (T1, T2, . . . , Tn). The processor(s) select tokens T′ (T′1, T′2, . . . , T′m) from the tokens T (T1, T2, . . . , Tn), where each T′j from T′ is a noun, and classify each T′j as a noun type. The processor(s) scan a corpus to identify passages with candidate answers to the question, and analyze the identified passages utilizing noun entries in the passages classified as the noun type. The processor(s) train an artificial intelligence (AI) system to associate a relevancy to the question for the identified passages based on noun types, and then utilize the trained AI system to provide an answer to the question based on an output of the trained AI system. |
