Abstract: A computer-readable recording medium stores therein a program for causing a computer to execute a process including: receiving, from an information processing terminal of a user, a start instruction for a conversation with a chatbot and attribute information of the user, obtained by the terminal; obtaining type information of the terminal; referring to a storage storing therein, for each user attribute, script information defining a process related to the conversation, determining, based on the attribute information, the script information to be used, and using the determined script information to start the conversation by the chatbot via the terminal, in response to the start instruction, when the type information corresponds to a specified information processing terminal; and displaying, by the terminal, information enabling selection of the script information, when the type information does not correspond to the specified information processing terminal, and using selected script information to start the c

Abstract: A storage device includes a first memory having a first access speed, a second memory having a second access speed slower than the first access speed, and a processor coupled to the first memory and the second memory and configured to copy one or a plurality of first data blocks included in a plurality of data blocks stored in the first memory, to the second memory, determine whether a processing amount per unit of time in the first memory reaches a threshold value based on a limit value of the processing amount when the processor receives a read request of a second data block included in the first data blocks, and read the second data block from the first memory when the processing amount does not reach the threshold value, and read the second data block from the second memory when the processing amount reaches the threshold value.

Abstract: Disclosed herein is an optical device, terminal apparatus, and system for wavelength division multiplexing (WDM). The optical device includes a WDM port adapted to WDM, a specific port to which a specific wavelength substantially central of WDM channels is allocated, a plurality of first ports to which longer wavelengths are allocated, a plurality of second ports to which shorter wavelengths are allocated, and first to fourth optical filters. The first optical filter couples the WDM port to the second optical filter by the specific wavelength, and also couples the WDM port to the second optical filter by the other plural wavelengths. The second optical filter couples the first optical filter to the third optical filter by the longer wavelengths, and also couples the first optical filter to the fourth optical filter by the shorter wavelengths. The third optical filter couples the second optical filter to the first ports, and the fourth optical filter couples the second optical filter to the second ports.
