  • Patent number: 11874882
    Abstract: A system for extracting key phrase candidates from a corpus of documents, including a processor, a memory, and a program executing on the processor. The system is configured to run a key phrase model to extract one or more key phrase candidates from each document in the corpus and convert each extracted key phrase candidate into a feature vector. The key phrase model also filters the feature vectors to remove duplicates using a classifier that was trained on a set of key phrase pairs with manual labels indicating whether two key phrases are duplicates of each other, to produce remaining key phrase candidates. The system uses the remaining key phrase candidates in a computer-implemented application.

  • Patent number: 11829374
    Abstract: Document embedding vectors for each document of a corpus may be generated by combining embedding vectors for document subparts, thereby yielding a final embedding vector for the document. A machine learning model is trained using a query corpus and the document corpus, where the model generates a ranking score for a given (query, document) pair. During training, rankings scores are generated using the model, such that the training dataset is further refined using the generated ranking scores. For example, top documents and a negative document may be determined for a given query and subsequently used as training data. Multiple negative documents may therefore be determined for a given query. A negative document for a given query may be determined from the negative documents using noise-contrastive estimation. Such determined negative documents may be evaluated using a loss function during model training, thereby yielding a more robust model for search processing.

  • Patent number: 11796310
    Abstract: The present disclosure discloses a fiber Bragg grating displacement sensor with positive and negative bidirectional measurement and free from vibration, which falls within the technical fields of fiber sensing and measurement monitoring, and aims to solve the problem that the measuring range of the existing fiber Bragg grating displacement sensor is positive, and the free end of the cantilever beam will generate vibration deformation, resulting in inaccurate displacement measurement. The sensor of the present disclosure has a positive and negative two-way displacement measurement range through the arrangement of a bidirectional measuring mechanism. In the measurement process, the cantilever beam of the vibration-avoiding mechanism is in an initial state of zero deformation, resulting in upper and lower bending deformation, so as to avoid the fatigue and failure problems caused by the cantilever beam and the fiber Bragg grating due to constant force.

  • Patent number: 11657223
    Abstract: A system for extracting a key phrase from a document includes a neural key phrase extraction model (“BLING-KPE”) having a first layer to extract a word sequence from the document, a second layer to represent each word in the word sequence by ELMo embedding, position embedding, and visual features, and a third layer to concatenate the ELMo embedding, the position embedding, and the visual features to produce hybrid word embeddings. A convolutional transformer models the hybrid word embeddings to n-gram embeddings, and a feedforward layer converts the n-gram embeddings into a probability distribution over a set of n-grams and calculates a key phrase score of each n-gram. The neural key phrase extraction model is trained on annotated data based on a labeled loss function to compute cross entropy loss of the key phrase score of each n-gram as compared with a label from the annotated dataset.
