摘要： A method is presented for error correction of tabular data in document conversion. The method includes identifying errors from tabular data transformation by employing an error/invalidation checking module and correcting the identified errors from the tabular data transformation by employing an error correction module. The error correction module includes identifying a main structure pattern from common row structures, concatenating separate keywords according to natural language processing models employing training data obtained from a plurality of candidate tabular data, adjusting cells in the tabular data based on a domain-specific knowledge database including the training data in combination with linguistic and semantic knowledge, merging partial tabular data pieces, and generating an adjusted table as output on a display of a computing device.

摘要： Techniques are provided for automated privacy scoring of user information. In one example, a system comprises a memory that stores computer executable components, and a processor that executes computer executable components stored in the memory. The computer executable components can comprise a privacy scoring component that employs a privacy identification model to generate a privacy score for a user and a product in the particular context based on information associated with the user and the product in the particular context. The computer executable components can also comprise a privacy enforcement component that implements one or more privacy features on the information based on the privacy score.

摘要： A computer-implemented method is provided for allocating a set of shared dockless bikes. The method includes providing a notification to a user of an availability prediction of a shared dockless bike, from among the set of shared dockless bikes, based on a trajectory of the shared dockless bike with respect to a current location of the user, and adding the user to a request queue associated with the current location of the user, responsive to the user agreeing to wait a specified time period for access to the shared dockless bike. The method further includes maintaining an available bikes queue for newly available shared dockless bikes, from among the shared dockless bikes, responsive to the newly available ones of the shared dockless bikes becoming available. The method also includes notifying users of the newly available shared dockless bikes in a priority order determined from the request queue.

摘要： A computer implemented method identifies guidelines through use of a neural network by a remote guideline server. A client computer transmits instructions to the remote guideline server to retrieve and evaluate multiple candidate guidelines. The remote guideline server utilizes a neural network to identify a string of terms found in each of the multiple candidate guidelines that match one or more strings of terms from a model guideline; to identify a semantic concept of each of the multiple candidate guidelines that matches one or more semantic concepts from the model guideline; and to identify a structural pattern of each of the multiple candidate guidelines that matches one or more structural patterns of the model guideline. The candidate guidelines that match the model guideline are then sent from the remote guideline server to the client computer.

摘要： Systems and methods for estimating battery-powered driving distance for a vehicle, including training a relative model for a battery using input historical battery temperature data and historical battery-external factors, and predicting a future battery temperature based on the relative model and one or more of current or future battery-external factors. A battery power capacity is determined using the predicted future battery temperature and input manufacturer specifications for the battery, and a remaining battery powered driving distance is calculated based on input vehicle power consumption data and the determined battery power capacity.

摘要： A method, a device and a computer program product for managing a shared vehicle are proposed. In the method, first information about a user is obtained. The first information indicates a speed of at least one shared vehicle used by the user. A target vehicle is determined from the at least one shared vehicle based on the first information. Second information about the target vehicle is determined. The second information indicates respective speeds of the target vehicle moving at a plurality of time intervals. An abnormal state of the target vehicle is detected based on the second information. The abnormal state indicates that a malfunction occurs in the target vehicle.

摘要： In an approach for automatically extracting product baseline information from a request for proposal document, a processor receives the document. A processor detects a table in the document. A processor identifies a table header on the table. The table header is associated with a name and an associated volume of the product. A processor extracts context based on the table header from the table. The context includes the name and the associated volume of the product. A processor maps the extracted context with the name of the product in the table to an associated name of the product based on a pre-defined product ontology.
