Abstract
The alpine skiing event is particularly vulnerable to changes in meteorological conditions as a winter sport held outdoors. The commonly used risk assessment methods cannot be inflexible and cannot be dynamically adjusted to combine multiple risk factors and actual conditions. A knowledge graph can organize data resources in the risk domain as structured knowledge systems. This paper combines a knowledge graph and risk assessment to effectively assess the risk status. First of all, we introduce the relevant literature review of sports event risk assessment, combining the characteristics of alpine skiing events. Then, we summarize the risk types of alpine skiing events and related risk knowledge. Secondly, a model is proposed to introduce an event risk assessment model based on the RippleNet framework combined with the characteristics of large-scale sports events. Moreover, the validity of the model is verified. The results show that the RippleNet-based event risk assessment model can be used to assess the risk of alpine skiing events. In order to effectively deal with the large-scale sports events that occur with a variety of risks, the smooth implementation of large-scale sports events provides a strong guarantee.
Highlights
The alpine skiing event is a winter competitive sport that is extremely challenging because of its high speed and high altitude
The analysis shows that the meteorological conditions required for the alpine skiing events cover precipitation, snowfall, visibility, temperature, relative humidity, wind speed, wind direction, etc
The experimental results show that the RippleNet model improves accuracy compared to the rule-based approach
Summary
The alpine skiing event is a winter competitive sport that is extremely challenging because of its high speed and high altitude. The International Ski Federation (FIS) regularly holds a series of events such as the World Championships, the World Cup, and the Winter. There are inevitably certain risks involved in holding a competition, including personnel safety, facility and equipment risks, logistics risks, and environmental risks [1]. Event organizers must thoroughly assess the possible risks during the competition and take preventive measures. Meteorological risk is one of the most critical risks in alpine skiing events. The impact of meteorological conditions on alpine skiing events can be reflected in two main aspects. The complicated topography and landform in the mountainous areas make the meteorological conditions more changeable
