Patent Application for Improved Sentiment Analysis Using Genetic Algorithm

Strategic Insights -

Developers at International Business Machines Corporation, led by inventors John P. Bufe, III and Timothy P. Winkler, have submitted a patent application detailing a novel approach to sentiment analysis using a genetic algorithm. This innovative methodology aims to enhance the performance and acceleration of domain adaptation in sentiment analysis. Sentiment analysis, a crucial aspect of natural language processing, involves determining the attitude or emotional tone of a speaker or writer, usually by classifying text as positive, negative, or neutral. The proposed technique leverages a genetic algorithm to train a sentiment analysis model, allowing for more accurate and efficient analysis of text data.

Key Takeaways:

  • The patent application describes a method for applying a genetic algorithm to compositional semantics sentiment analysis, enabling improved performance and accelerated domain adaptation.
  • Sentiment analysis involves determining the attitude or emotional tone of a speaker or writer, typically by classifying text as positive, negative, or neutral.
  • The proposed technique involves training a sentiment analysis model using a genetic algorithm based on a training corpus of documents with corresponding desired sentiment analysis values for a given domain.
  • The trained model is then applied to input documents to generate a domain-specific sentiment analysis result.
  • The system/apparatus for carrying out this method may comprise one or more processors and a memory, with the memory containing instructions to execute the operations outlined in the method.
  • Figures 1-11 illustrate the operation of the inventive system and technique, including block diagrams, flowcharts, and example parse trees.

Statistics:

  • 12 patents filed in 2013 by the inventors
  • 5 illustrative embodiments described in the patent application
  • 11 figures illustrating the operation of the inventive system and technique
