1. Natural Language Semantic Analysis Technique Using Large-scale Language Models
Use of natural language processing is growing in both the public and business realms, with advances in the technology being achieved using language models that model knowledge of human language by training neural networks on large quantities of text.
Given input text, language models can achieve high processing performance for tasks such as machine translation and automatic summarization. Hitachi, meanwhile, is seeking to achieve accurate understanding of written text through the development of core techniques that use language models. Examples include the development of techniques for converting business procedures into semantic representations that could be used by a machine or for summarizing the minutes of verbal meetings.
These core techniques that make use of language models are being developed through participation in international workshops that operate on a competition format, where they have performed well. In the future, Hitachi will deploy these new techniques in business to deliver improvements in people’s quality of life (QoL) through digital transformation (DX).
Note that the computational resources of the AI Bridging Cloud Infrastructure (ABCI) provided by the National Institute of Advanced Industrial Science and Technology (AIST) was used.
