  • System and Method for Classification of Unstructured Text Data
    Publication number: 20260162453
    Abstract: Certain examples described herein provide a system for classification of unstructured text data relating to a legal query. The system has a session interface to receive session data relating to the legal query, a text interface to receive unstructured text data from a user, a text pre-processor to apply one or more text pre-processing functions to the unstructured text data to output a structured numeric representation of the unstructured text data, at least one machine learning classifier to map the structured numeric representation of the unstructured text data to one or more classes within a defined set of classes, and a classifier optimizer to process the session data to generate configuration data for the at least one machine learning classifier, the configuration data indicating a subset of the defined set of classes that are valid given the session data.
