Abstract: Disclosed are a Nested Named Entity Recognition method based on part-of-speech awareness, system, device and storage medium therefor. The method uses a BiLSTM model to extract a feature of text word data in order to obtain a text word depth feature, and each text word of text to be recognized is initialized into a corresponding graph node, and a text heterogeneous graph of the text to be recognized is constructed according to a preset part-of-speech path, the text word data of the graph nodes is updated by an attention mechanism, and the features of all graph nodes of the text heterogeneous graph are extracted using the BiLSTM model, and a nested named entity recognition result is obtained after decoding and annotating. The present disclosure can recognize ordinary entities and nested entities accurately and effectively, and enhance the performance and advantages of the nested named entity recognition model.

Abstract: A key-value store and a file system are integrated together to provide improved operations. The key-value store can include a log engine, a hash engine, a sorting engine, and a garbage collection manager. The features of the key-value store can be configured to reduce the number of I/O operations involving the file system, thereby improving read efficiency, reducing write latency, and reducing write amplification issues inherent in the combined key-value store and file system.

Abstract: The present disclosure provides a positioning method, including: obtaining a current local topology map established based on objects in an environment currently observed by a robot, obtaining a full topology map pre-established based on objects in a full environment in a preset area, the current local topology map and the full topology map including nodes representing the objects; matching a node pair to be associated constructed by two nodes in the current local topology map and two nodes in the full topology map; if a degree of association of the node pair to be associated is greater than a threshold, determining that the node pair to be associated is an associated node pair; and determining a pose of the robot according to one of a plurality of search ranches, with a largest number of associated node pairs.

Abstract: A method for speed prediction may include obtaining current vehicle speeds associated with first vehicles that pass through a target road section in a current time interval. The method may also include determining a current road speed associated with the target road section in the current time interval based on the current vehicle speeds. The method may also include determining a predicted speed difference between the current road speed and a future road speed associated with the target road section in a future time interval based on the current road speed and a trained prediction model, which is based on prior speed differences, wherein the current time interval and the future time interval are separated by a first time period. The method may also include estimating the future road speed based on the predicted speed difference and the current road speed.
