Generative AI in Publishing

The Challenge

  • Better support in the search for solutions to legal issues
  • Supplement to the keyword-based search offered so far
  • Generative AI should be used to formulate answers with source references
  • Answers should only be extracted and generated from HJR content

The Solution

  • Organisation of a joint AI workshop to define the project
  • Development of a question-answer system
  • Combination of keyword-based and neural search
  • Docking of the Q&A system to a large language model

The Result

  • Customised solution that accepts complete questions + briefly formulated facts
  • Text-based and neural search algorithms identify relevant text passages from publishing products
  • Language model receives only this specific content, formulates an answer from it and adds corresponding source references

“With rehm eLine Smart Assist we use the current possibilities of generative AI specifically so that our customers can access complex legal matters more easily and quickly. The great advantage is the combination of natural question formulation, no need to sift through extensive hit lists, and a summarising answer as a result. In addition, the claim to legally secure information does not have to be abandoned because the answers are based exclusively on the well-founded, current content of the publisher. Overall, we are very close to the needs of our users and change the way information is found in their favour.“
