  • Patent number: 12450244
    Abstract: Methods and systems for log message aggregation include determining a first similarity distance score for a first incoming message by comparing the first incoming message to one or more stored templates. It is determined that the first incoming message imperfectly matches a matched template of the one or more stored templates, based on the first similarity distance score. A token in the imperfectly matched template is replaced with a wildcard, to reduce the first similarity distance score.

  • Patent number: 12444062
    Abstract: A computer-implemented method for visual question generation includes training an alignment module to analyze an image, an answer hint, and a visual hint with respect to the image. A k-nearest neighbors (KNN) graph is constructed by performing an aligned embedding for each region of the image. A node embedding component is generated by using a graph embedding component of the KNN graph. A visual question is generated by sequence decoding each image and graph of the image.

  • Patent number: 11966389
    Abstract: A method (and structure and computer product) of machine translation for processing input questions includes receiving, in a processor on a computer, an input question presented in a natural language. The input question is preprocessed to find one or more condition values for possible Structured Query Language (SQL) queries. One or more possible SQL queries are enumerated based on the one or more found condition values and a paraphrasing model is used to rank the enumerated SQL queries. The highest ranked SQL query is executed against a relational database to search for a response to the input question.
