Research On Chinese Voice Instructionsparser For Home Service Robot

Service robot is a hot research direction of robot technology. And making the home service robot in the complex environment be capable of family decision-making is also a hot spot in the field of the home service robot research. Therefore, in order to make the home service robot accurately and efficiently perform user instructions, and serve for humanity better, take advantage of the particularity of Chinese voice instructions for the home service robot, the dissertation do an in-depth research on Chinese voice instructions of the home service robot approach on natural language understansing and mission planning on the basis of the comprehensive analysis of research status at home and abroad.Firstly, the knowledge of jieba Chinese word segmentation and the answer set programming that are used in this dissertation are summarized. The dissertation also analyze the Jieba Chinese segmentation algorithm, keyword extraction algorithm, and the syntax, semantics and solver of the answer set programming.Secondly, the dissertation puts forward the system framework of the Chinese voice instructions parsing of the home service robot. At the same time, the dissertation pretreats the text information of the Chinese voice instructions of the home service robot. Natural Language Understanding is the key to make the robot accurately understand the task information given by the user. The text information of the instructions are segmented combined with the jieba Chinese word segmentation technology. The keywords are extracted with the help of a keyword extraction method. The sruface and deep information are obtained through analyzing keywords. The verb set format are obtained from transformational rule eventually.Thirdly, the dissertation discuss the mission planning fo the home service robot. Mission planning is the key to make the robot complete the task information more accurate and faster. The task informations do the task planning with the help of the answer set programming. And the dissertation designs a scene analytic strategy for multiple choice question and items to determine question. The actions sequences that the robot can accurate finish the task and cost minimality are finally obtained through the agreement between the mission planning and the action planning.Finally, the dissertation verify the feasibility and effectiveness of the natural language understanding and the missing planning for the Chinese voice instructions of the home service robot through experiment, meanwhile, combining with the experimental results, the accuracy of Chinese voice instructions of the home service robot are analyzed.
