  • Automation for Call Center
    Feature Word Extraction Engine

    While there is a demand for automation of call center to reduce the number of manned operations, this has been impossible to achieve with push-button automation due to the need for identification.

With these technologies, even people with low IT literacy can make the same inquiries as those made by conventional operators.

  • Chatbot to handle trouble inquiries
    Text Classification Engine

    We have developed a system that uses chatbots to investigate failures based on data collected from CRM and issue management systems that were not being used effectively. Chatbots conduct interviews on behalf of humans to find out the details of failures, and then inquire about the cases, and investigate the failures from a large number of cases. This has made it possible to save on labor for operators and reduce the time it takes to respond to inquiries.
