Chatbot Research and Development Using Deep Learning and the Watson API

「The research consisted of 2 projects: joint research with Nagoya University Hospital and research relating to a simple web-system development service. The joint research with Nagoya University Hospital aims to accelerate and improve the accuracy of searching the vast volume of documents used in medical settings by utilizing the company's document-search support service “DigiQuery.”」

「During the consolidated fiscal year, the company pursued research and development of AI-FAQ through its Tokyo Solutions Department. The research and development expenses related to a chatbot for automated responses to inquiries at call centers using AI-FAQ.」

「The company has addressed customers' needs for DX, work-style reform, and business transformation by providing solutions that use its own products, such as the paperless solution DigiPaper and MODEWO, an image-recognition AI development cloud service, as well as services provided by sales partners.」

「To meet demand for business transformation using digital technologies, including customers' DX initiatives, work-style reforms, and efforts to avoid the three Cs caused by the COVID-19 pandemic, the company began offering the paperless solution DigiPaper and MODEWO, an image-recognition AI development cloud service.」

「As technical verification required for the planned system, the company assessed applications using image recognition, paperless solutions, and speech recognition that operate on mobile devices. It will enable image recognition judgments to be used at locations without a network environment and commercialize AI judgments using trained models (object detection and image recognition), as well as AI applications using speech recognition.」

「During the consolidated fiscal year, the company pursued research and development using AI technologies developed by its AI Solutions Department. Through data analysis for image recognition using deep learning technology (Note 1), it acquired knowledge and conducted technical verification in machine learning, mathematical statistics, and data analysis methods. As technical verification required for the planned system, the company conducted research and development through the development of an internal chatbot using the Watson API (Note 2), including optimized information gathering, more efficient chatbot training, tuning, and optimized support, as well as technical verification of chatbot integration using speech recognition. The total research and development expenses incurred by the Group during the consolidated fiscal year were ¥13,735 thousand.」
