A method for real-time assessment of natural disaster losses based on social media data, specifically comprising the following steps: step 1, using natural disasters as keywords to obtain social media text data; step 2, extracting text data, and processing the data to complete the text Word segmentation and emotional calibration of data; step 3, establish natural disaster-related thesaurus and anti-thesaurus; step 4, clean text data based on natural disaster-related thesaurus and anti-thesaurus thesaurus and social media data geographic information; step 5. Set the analysis period, obtain the historical disaster data of natural disasters in the analysis period, establish a multiple linear regression model, and perform iterative calculations until the significance level of the model coefficient is less than the set threshold.

The invention provides a knowledge graph Chinese question answer retrieval method based on a dynamic programming algorithm. The method aims at modeling the original question answering process comprising three substeps into the same process in a unified mode, the entity recognition process and the question answer retrieval process are modeled with a same model by integrating thoughts of a state machine in form language, the entity recognition process is modeled into the process of transferring the state of the system from the original state 0 to the state 1, and the question answer retrieval process is modeled into the process of transferring the state from the state 1 to the state 2. The precise and the scope of an answer are guaranteed, and the overall question answering process can be subjected to unified modeling macroscopically. In addition, the target entity transferring process in the question answering process is modeled into the state transferring process in the state machine,a transfer entity is modeled to be in an intermediate state, and a final answer is modeled to be in a termination state. On the basis, the transfer process of all the states achieves decision supporting as a whole through the dynamic programming algorithm, and meanwhile the operation efficiency of the system is guaranteed.

The invention discloses an air conditioner control system and a multi-tube-nest air conditioner. The air conditioner control system comprises an outdoor unit assembly and two or more groups of indoor units. Each group of indoor units communicate with the outdoor unit assembly through a refrigerant pipeline. Confluence pipeline sections of the refrigerant pipelines where the corresponding indoor units are located are provided with throttle valves which are connected in parallel. Check valves are arranged between the refrigerant pipelines where the indoor units are located and the adjacent throttle valve pipelines, and the check valves are used for controlling the corresponding indoor units to be connected with the system to work or not. Intersecting pipeline sections of the refrigerant pipelines of the indoor units are connected with the throttle valves which are connected in parallel. Because the pipelines are connected into the multiple throttle valves in parallel, the controllable adjustment range of flow control amounts to the sum of the control sections of all the throttle valves connected in parallel, and the air conditioner control system can be fully adapted to the work demand that multiple indoor units are connected in parallel; when the number of the working indoor units connected into the system is small, a part of the throttle valves connected in parallel can be directly closed, and only one independent throttle valve is used for connection control; and therefore, the range of the refrigerant flow adjusting area controlled by the throttle valves and the control accuracy are guaranteed.

This refrigerator is provided with: an outer shell body having a storage chamber the front surface of which is open; shelf rails being provided in respective inner wall surfaces of the storage chamber and each extending in a front-and-rear direction; and a front shelf and a rear shelf which are separated from each other in the front-and-rear direction so as to be disposed at the opening side and the deep side of the storage chamber and which are supported on the shelf rails. Claw parts that engage with the shelf rails are provided to respective side edges of the front shelf. In the rear shelf, notches are formed at positions corresponding to the claw parts of the front shelf when the front shelf removed from the shelf rails is stacked on the upper surface of the rear shelf.
