Purpose Soccer-related social media BigData includes complex information related to soccer players and is continuously and instantly generated. Text mining research is actively carried out for this kind of social media contents analysis, but it tends to be analyzed with limited linguistic characteristics such as understanding of language complexity and context, ambiguous terms, rhetoric, and new terms. This can be attributed to the fact that the tools commonly used for text mining use universal terminology dictionaries and packages that exclude the peculiarities of the analysis themes. The purpose of this study is to develop an Ontology model, which are representative tools for defining semantic ambiguity and relationships and systems between terms of text data. Methods In order to achieve the research objectives, we applied the 7-step development method of ‘Ontology Development 101: A Guide to Creating Your First Ontology’, which is useful for ontology development. Each step includes 1) Determine the domain and scope of the ontology 2) Consider reusing existing ontology 3) Enumerate important terms in the ontology 4) Define the classes and the class hierarchy 5) Define the properties of classes-slots 6) Define the facts of the slots 7) Create instances. In particular, the 3rd-step of this study, the glossary stage, is to extract core terms that make up he ontology, but since the goal of this study is to develop the ontology that can be used in social media contents analysis of soccer players, we conducted a social media text analysis related to actual soccer players and selected 484 core terms. Results The ontology which was developed in this research for social media contents analysis of soccer players consisted largely of four parts(General terms, performance results terms, common terms, and Characteristic term) and classified according to the content characteristics of the term. Conclusion Developed ontology in this study is object-oriented that defining classes and objects to define divisions and relationships between terms and also means a social media contents knowledge system of soccer players. In addition, it performs a function as a secondary tool which can be utilized for atypical data analysis.
Purpose The purpose of this study was to compare the differences between the three simple control models of Hayes (2012) and to determine whether there were Moderating Effects depending on the level of self-esteem, willpower and belief that are psychological factors in the relationship between athlete's retirement and Athlete's period. Methods To achieve this objective, a total of 259 retirees were collected from data on retirement and psychological factors. The data processing method presented the reliability and feasibility of the measuring instrument through technical statistics, frequency analysis, confirmation factor analysis, and reliability analysis. In addition, we conducted a hierarchical regression analysis using the PROCESS command statement in IBM 20 to examine the regulatory effects. Results The results of the study are as follows: The first was the significant model of Hayes (2012)'s three simple control models. It is up to the researcher to choose which model to choose, but when selecting the model, the justification of the variables must be established on the basis of theoretical basis, and the reliability of the variables must be put in to produce reliable and reasonable results. The second was to verify that the relationship between the retirement factor(10) and the Athlete's period has an adjustment effect based on self-esteem, willpower and belief. Among the psychological factors, the Moderating Effects was greatest in the influence of belief on the Athletes' period, and the more reasons for retirement, the longer the Athletes' period than the weaker. The combined mental strength of all three psychological factors combined shows that the combined effect of control also significantly increases the player's ability to survive by combining with the retirement factor. In particular, sportsmanship has resulted in a better mix of retirement factors than the sense of Self-esteem and will, resulting in a longer increase in the capacity. Conclusions Therefore, players who long for a player always keep their dreams of becoming a big star in mind, and ask me to always keep the belief in hope that I will enjoy my career for a long time.
