The purpose of this study was to compare the cruise tours between China and U.S.A. through the semantic network analysis of big data by collecting online data with SCTM (Smart crawling & Text mining), a data collecting and processing program. The data analysis period was from January $1^{st}$, 2015 to August $15^{th}$, 2017, meanwhile, "cruise tour, china", "cruise tour, usa" were conducted to be as keywords to collet related data and packaged Netdraw along with UCINET 6.0 were utilized for data analysis. Currently, Chinese cruisers concern on the cruising destinations while American cruisers pay more attention on the onboard experience and cruising expenditure. After performing CONCOR (convergence of iterated correlation) analysis, for Chinese cruise tour, there were three clusters created with domestic destinations, international destinations and hospitality tourism. As for American cruise tour, four groups have been segmented with cruise expenditure, onboard experience, cruise brand and destinations. Since the cruise tourism of America was greatly developed, this study also was supposed to provide significant and social network-oriented suggestions for Chinese cruise tourism.

The cruise industry in the Mediterranean region increased from 2000-2018, being the second most important region after the Caribbean. The purpose of this study was to analyze the networks and hub ports of the Mediterranean. This paper used the SNA (Social Network Analysis) methodology, which includes Hub and Authority Combined Centrality (HACC) that has been used to analyze cruise port centrality, as well as degree centrality such as In-Degree, Out-Degree, and Betweenness. This empirical study suggests that the top three ports of the Mediterranean ports' network in terms of hub index are Barcelona, Civitavecchia, and Palma de Mallorca. The academic implications are the suggestion for data integration based on real itineraries and numbers of POC (Port of Calls), as well as the selection of the hubs of the targeted areas. The practical implications are suggested such as a clear requirement for cruise industry, as a way to widen the scope for the Mediterranean region and a valuable reference for cruise ship companies to select the best fit home ports.

본 연구에서는 제주도, 상하이, 요코하마 크루즈 항만을 비교하여 제주도가 가지는 강점과 약점을 알아보는 것이다. 이를 위해 Cruise Network 분석 프로그램을 통하여 8개요인(공항, 선석, 비용, 거리, 시내접근성, 쇼핑시설, 소스마켓(배후시장), 관광)비교를 통하여 평가하였다. 세 개의 크루즈 항구를 비교하여 평가한 결과 제주도는 민군복합항을 완공하여 크루즈 2개선석(접안능력)을 확보하는 것만으로도 상하이 크루즈 항만보다 우위에 있을 수 있고, 신공항이 완성되면 요코하마 크루즈 항만보다 우위를 점할 수 있어 향후 동북아시아 최고의 크루즈 항만의 조건을 갖출 수 있을 것이라는 결과를 얻을 수 있었다. Cruise Network 분석 프로그램을 통하여 얻은 결과는 행정 정책이 뒷받침이 되어야 한다는 과제를 안고 있다. 이 연구가 크루즈 항만의 특성 및 배후지 평가를 위항 8개의 요인만을 가지고 각각의 지역을 평가하여 결과를 도출한 점은 평가 대상지지역의 다양하고 복잡한 여건을 충분히 종합하지 못한 한계를 가진다. 그리고 향후에는 크루즈 항만에 대한 평가요인을 세분화 하여 평가할 필요성이 있다. 또한 향후 연구에서는 크루즈 산업의 경제적인 효과와 융 복합 산업으로서의 관련 산업에 대한 연관성을 연구해 볼 필요성이 있을 것이다.

세계적으로 해양산업은 크루즈산업에 많은 관심과 연구가 대폭적으로 이루어지고 있고 우리나라도 미래의 잠재력 있는 국가동력산업의 하나로 인식하고는 있으나 크루즈산업의 연구동향 분석 연구는 국내외에 활발히 이루어지고 있지 않다. 따라서 우선 세계 크루즈산업을 연구하고 이해하기 위해서는 최근에 다양한 산업에 대한 연구동향을 분석한 방법을 활용하여 크루즈산업에도 적용할 필요가 있다. 본 논문의 목적은 외국 유명저널에 발표된 크루즈산업과 관련된 학술논문에서 제시하고 있는 키워드와 논문을 매개로 한 키워드 네트워크를 구축하여 복잡계의 네트워크 분석에서 사용하는 연결 중심성과 매개 중심성 분석방법으로 시대별로 나누어 시각화하여 살펴봄으로써 세계 크루즈산업의 연구동향을 심층적으로 관찰하여 논의하는 것이다. 본 연구에서 제시된 키워드 빈도는 Zipf의 법칙을 따르고 노드의 연결정도는 멱함수 분포를 보여주고 있어 언어네트워크에서 분석하는 키워드 네트워크와 동일함을 관찰한다. 연구방법론으로는 키워드 네트워크 분석을 위하여 사회연결망 프로그램인 넷마이너 4.0을 사용하여 여러 가지 중심성 측정방법 중 키워드 상위 20개의 빈도순위를 비교하여 빈도순위와 가장 가까운 중심성 측정방법을 선택하여 크루즈산업의 연구동향을 분석한다. 특히 크루즈산업의 연구동향이 연도 기간별로 어떠한 변화를 가져왔는지를 살펴보기 위해 2000년 이전과 2000년 이후로 크게 대별하여 나누고 2000년 이후에는 5년 주기로 각 기간별 공통적으로 나타나는 연결 중심성이 높은 최상위의 키워드인 cruise와 tourism 노드를 중심으로 매개 중심성이 높은 것들의 키워드 네트워크를 시각화하여 논의한다. 연구결과에서 흥미롭게도 2010-2014의 기간에 새로운 노드로 China가 등장하여 최상위의 키워드들을 연결하고 있는 것은 최근 급성장하고 있는 중국의 크루즈산업의 발전 양상을 보여준다. 그러므로 본 연구에서 사용하는 키워드 네트워크 분석은 각 연도 기간별 네트워크의 다른 종류의 숫자와 크고 작은 중심축 군집 네트워크의 숫자의 증감뿐 아니라 중심축 군집 네트워크의 중심에 있는 키워드 간의 연결 분석을 용이하게 해주어 기간별 연구동향을 파악하는데 유용한 방법임을 확인할 수 있었다.

This study is to analyze the structure of the networks of tourism marketing on Twitter, identifying the most prominent users, the flow of information about tourism marketing, and the interaction between the users posting tweets. This study employs NodeXL pro as a visualization software package for social network analysis. The number of vertices or nodes is 171, and the number of the unique edges or links is 128, but there are 101 edges with duplicates, so the total links are 229, which means that there are fewer Twitter accounts in the social network on tourism marketing, but they have a few close relationships by sharing information. The research can map the social network of communicators of tourism marketing using Twitter data. The network has a complicated pattern, including one independent network and some connected networks. Some mediators connect each network and can control the information flow of tourism marketing. More communicators are getting the information than the ones providing it, which means that there is likely to be the dependence of information among communicators that can cause an obstacle and distortion of the information flow system, especially in the independent network.

The purpose of this study was to visualize the semantic network with big data related to food exhibition at convention center. For this, this study collected data containing 'coex food exhibition/bexco food exhibition' keywords from web pages and news on Google during one year from January 1 to December 31, 2016. Data were collected by using TEXTOM, a data collecting and processing program. From those data, degree centrality, closeness centrality, betweenness centrality and eigenvector centrality were analyzed by utilizing packaged NetDraw along with UCINET 6. The result showed that the web visibility of hospitality and destinations was high. In addition, the web visibility was also high for convention center programs, such as festival, exhibition, k-pop and event; hospitality related words, such as tourists, service, hotel, cruise, cuisine, travel. Convergence of iterated correlations showed 4 clustered named "Coex", "Bexco", "Nations" and "Hospitality". It is expected that this diagnosis on food exhibition at convention center according to changes in domestic environment by using these web information will be a foundation of baseline data useful for establishing convention marketing strategies.
