The Design And Implementation Of Intelligent Old-age Care Service System Based On Multi-tenant Structure

With the number of elder increasing sharply,burden of labor force population is getting heavier.The problem of taking care of elder people has become one of the most serious problems of people's livelihood.Under this background,using Internet technology to light the pressure of middle-aged crowd and achieving the goal of intel igent old-age care has become a major subject to be study.The goal of research in this paper is to develop a system based on cloud computing to intelligentialize old-age care system.The major part of this paper can be divided into three parts.The first part of this passage is about the characteristics of multi-tenant structure in software,including self-help enrollment,personalized setting,data isolation and data safety protection.The second part of this paper introduces the whole procedure of software design which includes requirement analysis,outline design and detailed design.Then this paper designs some case to test the system both in function and performance.The third part of this passage is mainly about algorithm of recommendation system.The whole process of recommendation are divided into two steps.One step is to recommend service,the other step is to recommend server.This passage introduce a two-stage neighbor choosing algorithm based on item to promote the accuracy of choosing neighbor and using Logistic regression based on server gene to predict the score of server who may be chosen by aiming user.The experiment uses the dataset in our database to test the performance of the algorithm.The result shows that the promoted algorithm is better than the traditional item-based collaborative filtering algorithm.Tested in the real situation,this system can provide an excel ent service for the elderly,and provide a solution to solve the same problem.
