This invention discloses an intelligent emergency call method and system, applicable to any user group in an emergency situation, including the elderly, women living alone, and patients with chronic diseases. It can run on various smart terminals such as smartphones, smartwatches, and smart bracelets. After a user triggers the call with one click, the system uses a multi-round cyclic dialing strategy to dial multiple emergency contacts sequentially, with subsequent rounds only dialing those who did not answer. Accurate answer determination is achieved by obtaining the actual call duration (zero indicates no answer). Simultaneously, it automatically integrates the GPS reverse geocoding address with the user's health record into a structured emergency call notification message and sends it. The entire process includes voice guidance, and all interactive nodes employ a countdown default continuation mechanism to ensure the process is not interrupted due to user inability to operate. This invention solves the three major defects of existing technologies: slow response, frequent misjudgments, and incomplete information. The entire process is triggered with one click and executed automatically.

The embodiment of the invention provides a multilingual address generation method, an address generation model training method, an address-based risk control method, an order address auditing method, electronic equipment, a storage medium and a computer program product. The method comprises the following steps: calling a preset agent based on a preset cue word, and triggering the preset agent to generate longitude and latitude data in batches; taking the latitude and longitude data and a target language as input parameters, calling a preset reverse geocoding service, and obtaining a coding result, the coding result comprising an address of the latitude and longitude data corresponding to the target language; and filtering the addresses based on the addresses and / or the confidence coefficients of the addresses to obtain a set of the addresses of the target language. The multilingual address generation method effectively improves the quality of the generated multilingual address.

This invention relates to the field of supply chain demand forecasting technology. Specifically, it relates to a supply chain demand forecasting method and system based on multi-source heterogeneous data fusion. The aim is to address the problem in community group-buying scenarios where sudden surges in localized orders easily generate noise, leading to distortion after the fusion of these surges with multi-source data, affecting the accuracy of demand forecasting and hindering automatic replenishment decisions in the supply chain. The method involves real-time collection of community group-buying order locations and sales volumes, using reverse geocoding to unify the format; after identifying surges in orders, density clustering is used to calculate the coverage radius and classify the data, matching noise intensity coefficients and hysteresis correction amounts, and combining a negative exponential function to generate a dynamic attenuation coefficient, thus doubly correcting surges in sales volume; the corrected data is then fused with e-commerce transaction and store inventory data, standardized, and input into a recurrent neural network model to output regional demand forecasts for the next seven days, triggering automatic replenishment decisions and improving forecast accuracy and supply chain responsiveness.
