2results about How to "Improve search quality" patented technology

The application discloses a multimodal code search method based on fine-grained attention alignment, constructs a new mechanism to learn the rich semantics of source code and natural language queries from two modalities of text and structure, uses a multimodal feature network to construct a code search model, adopts different construction methods for different modal features, and fully expresses different features of corresponding codes and texts; meanwhile, a fine-grained alignment mechanism is adopted in the model training process, and the same modal features are aligned respectively, thereby facilitating the matching of code entities and text entities; after the construction of all features is completed, a cosine similarity function is used to calculate the similarity between a given query and code samples in all code libraries, so that the code samples are ranked according to the similarity. The application gets rid of the insufficiency of code representation and feature extraction in the existing code search field, can more completely utilize the information contained in different modal features for code representation and matching, and has higher recognition accuracy and better convergence performance.

The application discloses a search quality real-time evaluation method and device, equipment and a storage medium, and relates to the technical field of Internet, and comprises the following steps: a sample pool construction module is used for online search based on each preset search vocabulary and corresponding prediction category and entity recognition result to determine a corresponding number of positive and negative samples to obtain a target commodity sample pool; a vocabulary routing module is used for judging whether a target search vocabulary currently input by a user belongs to a preset search vocabulary, and if yes, the target search vocabulary is routed to the target commodity sample pool to perform a search operation; a data uploading module is used for storing detailed data of each search stage into a preset persistent database based on a preset burying point when the search operation is performed; and a quality evaluation module is used for determining a quality evaluation result based on the detailed data and each preset quality index formula. The application determines the search quality by evaluating the detailed data of each search stage when the preset search vocabulary is input, and effectively guarantees the real-time performance of the evaluation.
