  • Patent number: 11574554
    Abstract: A goal management system receives input of a qualitative first goal related to a body of a user (step S111), identifies a quantitative second goal related to the body of the user from the first goal thus received (step S112 to step S117), and presents the second goal thus identified (step S118). The first goal is converted into the quantitative goal for at least one of a plurality of feature amounts related to the body, thereby identifying the second goal including at least one goal obtained by such conversion. The first goal is converted into the quantitative goal for each feature amount corresponding to a meaning obtained by linguistic analysis. When there are a plurality of meanings obtained by linguistic analysis of the first goal, the first goal is converted into the quantitative goal for each feature amount on the basis of a range of each feature amount per meaning.

  • Patent number: 11457838
    Abstract: Whether intervention is necessary is assessed due to an occurrence of a divergence of a current value of a predetermined index from a route corresponding to a transition in value of the predetermined index to a target value of the predetermined index for reaching a target relating to a body of a user (steps S141 to S147), and, when intervention is assessed to be necessary, using an intervention result per each of persons intervening relating to a target index stored in a storage unit, a person with a high contribution toward reaching the target from among persons intervening for the user is determined (steps S151 and S152), and processing for prompting the determined person for intervention is executed (step S155). A timing with a high contribution is determined using an intervention result stored in the storage unit that further stores intervention results per each intervention timing relating to a target index.
