Context Awareness And Active Service Technology For Home Pension Services

With the increasing population of the old in china,aged-care at home becomes a new pension plan.The old man's requirements statement is vague and untimely,it is necessary to automatically obtain the elderly's requirements needs and provide spontaneous services.This thesis is based of Home Pension Services,it researches and analyses the concept of requirements,requirements patterns,services and service patterns in Home Pension Services.An ontology-based Home Pension Services context model has been established,and this thesis reposed the use of context-aware technologies to capture the requirements of the elderly,constructed service plan using service selection method for balanced Qo S and applied verification in the field of Home Pension Services.In the theory Part,firstly,it studies the characteristics of Ho me Pension Services,and proposes an ontology-based Home Pension Services context model.Then this thesis uses context-aware technology to capture the behavior and requirements of the elderly.Specific research methods include based on Rando m Forest and Behavioral Similarity,two-level behavior recognition algorithm for the aged at home,requirements inference algorithm for elderly people based on rules pruning,and requirements reasoning algorithm for elderly people based on reinforcement evidence theory,and through a large number of experiments to verify the correctness and performance of the algorithm.The old man's behavior recognition algorithm proposed in this paper can accurately identify the behavior of the elderly,and the accuracy rate reached 95.59%.And the proposed rules-based pruning and reinforcement evidence reasoning algorithms,on one hand,it can quickly infer the requirements of the elderly,on the other hand,it can solve the Zadeh paradox and can infer the requirements of the elderly in the anti-conventional and abnormal situations of the elderly,and the accuracy rate reached 98.65%.Finally,the technology of active service is used to provide services for the elderly autonomously.Specific research methods include: requirements patterns decomposition and mapping generate service flows,service selection methods for balanced Qo S,and Context UML-based service execution technologies for context-aware service initiative execution templates,and the method proposed in this article can quickly and accurately construct and implement services for the elderly.In application verification part,firstly,the thesis need to analyze and design the context-aware service tools for home care services,it apply the designed algorithm to context-aware service tools,and manage the context,requirements,service and other information.In the field of Home Pension Services,Validate the proposed method and prove the validity and applicability of the method.
