Switzerland is one of the most desirable European destinations for Chinese tourists; therefore, a better understanding of Chinese tourists is essential for successful business practices. In China, the largest and leading social media platform—Sina Weibo, a hybrid of Twitter and Facebook—has more than 600 million users. Weibo’s great market penetration suggests that tourism operators and markets need to understand how to build effective and sustainable communications on Chinese social media platforms. In order to offer a better decision support platform to tourism destination managers as well as Chinese tourists, we proposed a framework using linked data on Sina Weibo. Linked Data is a term referring to using the Internet to connect related data. We will show how it can be used and how ontology can be designed to include the users’ context (e.g., GPS locations). Our framework will provide a good theoretical foundation for further understand Chinese tourists’ expectation, experiences, behaviors and new trends in Switzerland.
Switzerland, as one of the most desirable European destinations for Chinese tourists, is strongly positioned as a steep and consistent quantitative growth market. At the end of 2013, there were a total of nearly 1 million overnight stays in Switzerland for Chinese travelers. China ranked 6th in terms of total overnight volume, 5th in turnover and 3rd in daily expenditure (330 CHF) [
With the rising popularity of traveling websites (e.g., TripAdvisor) and social networking sites (e.g., YouTube, Facebook) that contain information submitted by tourists, the ways that travelers search for and evaluate travel information are changing [
In China, the largest and leading social media platform―Sina Weibo, a hybrid of Twitter and Facebook― now has over 600 million users and is currently regularly used by more than 140 million users. Weibo’s great market penetration suggests tourism operators and markets need to understand how to build effective and sustainable communications on Chinese social media platforms. By analyzing Chinese consumers’ Weibo activities, it is possible to learn about their characteristics, interests, preferences and concerns, as well as their expectations and experiences in Switzerland.
However, the tourism decision making is difficult, both for tourists as well as tourism destination managers, due to the complexity of the large number of information within this industry. As for Chinese consumers abroad, the issues to be addressed relate to food, accommodation, transportation, language, shopping, entertainment, weather, etc. For tourism destination managers, the massive nature and complexity of data also make it difficult to make decisions. Furthermore, Chinese people have changed significantly of their ways and consumption behaviors recently, leading to the dynamic changes of tourism data. Using traditional ways to collect data from group tourists and industry statistics to estimate the volume of demand might be problematic because it takes long time and may not capture the individual trips. Therefore, it is necessary to identify up-to-date changes, and make timely management decisions to better attract Chinese tourists and provide better services.
Linked Data is a term referring to using the Internet to connect related data. This term is often used to describe a recommended best practice for exposing, sharing, and connecting data, information, and knowledge on the Semantic Web using URIs and RDF. It is an important factor for improving the quality of natural language processing (NLP), such as user’s interpretation from social media platforms. Many NLP tasks can greatly benefit from making use of this wealth of knowledge available on the Web in a structured form such as Linked Data. For tourism destination mangers, they want information presented in a format that effectively assists them in making decisions. We believe that semantic technology based linked data can help to identify Chinese tourists’ behavior and their consumption trends, which in turn help managers to better manage the tourism destination.
Nevertheless, although several researchers have addressed the perceptions of Chinese tourists about certain destinations to check their intention to visit, we argue that these studies are somehow subjective because the participants in these studies do not know or have never been to the destination. However, there are far fewer studies which have empirically examined real Chinese tourists’ attitudes and experiences (e.g., on social media platforms). Even fewer have analyzed the positioning of Switzerland as a destination for Chinese tourists. Research on linked data with behavior analysis in this field is also notably lacking.
The goal of this research is to study decision support system by adopting a linked data approach. We intend to build this framework on a Chinese social media platform with a large-scale analysis with linked data and explore Chinese tourists’ attitude and behavior towards Switzerland. We selected Sina Weibo, which has played an important role as a powerful media channel to extend personal networks and informal information sources, as our use case to describe this framework. Future research should use real data to validate it.
The study mainly draws upon the literature relative to user generated content and, in particular, the influence on tourism of such content from social media. In the next section, we will first present the development and analysis of the Chinese tourism market in Switzerland and then discuss the related work of user generated content and tourism.
Tourism has been considered as one of the most important economic activities in the world, both for developing and developed countries. People all over the globe are more willing to spend on traveling. As a consequence, the tourism industry has accumulated extravagant economic contributions. According to the World Tourism Organization (WTO) in 2013, about 9% of the world’s Gross Domestic Product (GDP) is generated by the tourism sector. International tourist arrivals worldwide reached a record 1087 million, and these are expected to grow to 1.8 billion by 2030. China leaped to first place in the ranking by international tourism expenditure in 2012. In 2013, it consolidated its position as the number one tourism source market in the world, spending US$129 billion on international tourism.
Compared with other counties, Switzerland is strongly positioned as a steep and consistent quantitative growth market. In 2013, the overnight stay of mainland Chinese tourists in Switzerland reached 994,456; an increase of 19% as compared to the year 2012. It is expected that there will be a high market potential for Chinese tourists in Switzerland in the following years due to a very high GDP growth and the high share of young and first-time visitors. Taking advantage of increasingly fewer restrictions on travel visas, as well as an appreciating currency, Chinese consumers will continue to accumulate economic contributions for Switzerland. In 2012, Chinese visitors spent a total of 3 billion francs on luxury goods and souvenirs in Switzerland.
While many Chinese tourists still travel in Switzerland in organized groups due to the linguistic barriers, this trend is changing. Individual trips are expected to increase in the next few years, particularly among experienced tourists. The reason is probably because long-distance Chinese tourists who belong to a middle-high social class not only have greater purchasing power, but they are also better educated and have better knowledge of other languages, as reported by the [
The main reasons for Chinese tourists to visit Switzerland are the following [
In a travel context, consumers often spread word of mouth (WOM) due to the fact that traveling is associated with a product―experience. Research has indicated that, due to the lack of commercial self-interest associated with WOM recommendations, consumers tend to trust and be more influenced by this type of information than by more commercial sources such as travel agents or accommodation operators ([
As in the online environment, recommendation sources can come from other unknown consumers, and there is far more information available than from traditional WOM. Today, many websites allow users to add their own content. Such content is known as User Generated Content (UGC). Individuals can learn more about tourist destinations, conduct detailed trip planning and seek out the best price or value through the Internet via UGC [
However, the quality of the information and the expertise from these sources sometimes varies tremendously. UGC has become one of the most influential information sources for traveling decision making. [
The flourishing promise of UGC is now being hyper-realized with social media. In China, the most prevailing social media platform is Sina Weibo. Launched on August 28, 2009, Sina Weibo is growing at an astonishing rate. By the end of 2013, its registered users had reached 600 million with 143.8 million active monthly users. More than 5000 companies and 2700 media organizations in China use Sina Weibo. The current volume of weibos (microblogging messages on Sina Weibo, like tweets in Twitter), is over 2.8 billion per month. By providing an unprecedented and simple way of communicating, Sina Weibo allows people to publicly express themselves in real time, interact with others, as well as be heard publicly and be exposed to the rich ideas, cultures and experiences of the broader world. Traditional media uses Weibo as a distribution channel for their headline news. Government agencies and officials use Weibo as an official communication channel for disseminating timely information and gauging public opinion to improve public services. Companies use Weibo as a key marketing tool to seize market opportunities and boost their presence, thus maximizing their business values in China.
Sina Weibo users tend to be young―the vast majority is under the age of 32―and better educated, wealthier than the general population. Many use Weibo to keep up with current events. The demographic characteristics are similar to the majority of individual tourists to Switzerland who want to decide by themselves about the place and directions. Therefore understanding Chinese tourists’ expectations and experiences with regard to Swiss tourist products will provide interesting insight.
Research on characteristics of user behavior on the Sina Weibo is available. For example, [
This paper is part of linked data based tourism decision support system research program. The main objective of the current stage is to propose a framework towards a tourism decision making support system platform. Such framework is expected to identify Chinese tourists’ expectations and their real experiences in Switzerland, and therefore understand their consumption patterns to support tourist manager’s decision and to provide better services to Chinese tourists.
In this section, we propose a framework of linked data based tourism decision support system.
As of the preliminary stage, the dataset can be collected via the Sina Weibo Open API, which has been open since July, 2010. Sina Weibo represents the convergence of user text commentaries with photos, video, and mu-
sic in a simple and user-friendly way, allowing users to create, distribute, discover, share and communicate Chinese language content. Developers or websites can create creative applications to access the information on Weibo through the Open API platform. Two types of datasets can be considered here: user profiles and micro blogs (weibos). The profiles contain the user’s demographic information, such as login name, real name, location, gender, date of birth, education and profession, as well as other information such as uses preference and network, including preferred tags (e.g., travel, movies, food, etc.), the number of micro blogs, and the list of followers and followings. For the purpose of our research, our attention would focus on the content related to Switzerland, including their text messaging and location information. However, using the subject “Switzerland and travel” as the only keyword to search the Weibo database will not capture enough important information, because in many cases the user’s micro blog only contains information related to Switzerland, such as the name of a city in Switzerland, but does not explicitly mention the word “Switzerland” or “travel” in the text message. Therefore, to increase the validity of this research, it is necessary to build a multiple language Switzerland based ontology as the first step before collecting data from Weibo. The design of this ontology will focus on its class and property for the administrative units and the most evidence units of Switzerland, such as the points of interest, famous buildings, and the most visited places, in which the triple data are linked to other data from existing ontologies, for instance, Geonames, DBPedia, Word Net, and data.admin.ch. Moreover, user location information could also help to provide additional information on Swiss related data. By building this ontology, other domains such as luxury products, food, education, job opportunities, economic and commercial authorities may also possibly be included in future research.
To match the business needs of this research, it is necessary to build an ontology-based system that includes two languages-Chinese and English, representing over 99% of micro blogs. The objective is to create the knowledge from unstructured sources, such as user’s text. Therefore, two main methods are applied to achieve the objective: text mining and multilingual natural language knowledge extraction. Text mining is a domain of natural language processing (NLP), a computer science field where machines extract knowledge from text written in natural language. In most NLP tasks, machine learning tools have been successfully used for years. The downsides of this approach are the amount of human work to annotate existing corpus to train the system, and the limitation of the system that becomes efficient only for the domain it has been trained for. Recently, knowledge based techniques have yielded comparatively good results, and even better results in some cases, as demonstrated by [
Information retrieval and ontology-based classification techniques are used to calculate frequency of certain text, attempting to identify the most relevant elements of a corpus to satisfy the information retrieval. An ontology represents knowledge as a hierarchy of concepts within a domain, using a shared vocabulary to denote the types, properties and interrelationships of those concepts [
In this step, Fayyad et al. [
・ Anomaly detection: the identification of unusual data records, that might be interesting or data errors that require further investigation. In this task, we identify the collected Weibo dataset which is not in conformity with an expected pattern.
・ Association rule learning: searches for relationships between variables. We define association rule learning for discovering interesting relations between user variables in Weibo databases.
・ Clustering: is the common descriptive task to identify a finite set of categories or clusters to describe the data. This task is used to combine the objects in the same group, similar to the data retrieval method that we introduced in the previous section.
・ Classification: is the task of generalizing a known structure to apply to new data. In this step, we identify and map the user’s natural language in Weibo’s interpretation as a data item into one of several predefined
classes with the linked data.
・ Regression: is learning a function that maps a data item to a real-valued prediction variable. This task is used to predict Chinese consumer behavior in Switzerland, such as purchasing power, desired service, interesting place products, etc.
・ Summarization: providing a more compact representation of the dataset, including visualization and report generation for the final exploratory data analysis in this study.
This is an important step to delivering visualized and understandable data to the DSS and services. For example, Chinese tourists’ preferred destinations and accommodations can be displayed on a map with the frequencies and consumption information. Firms or service providers can also use business model canvas as a visual chart and useful tool to describe and design new or develop existing business models to illustrate potential trade-offs before make any tourist related decisions.
Based on new data form analysis, the final step is to build the user interface to communicate with the tourist destination managers and service providers. All data that has been collected, classified, analyzed and visualized from the massive and complex data in Sina Weibo in previous steps should be easily interacted with users. The final tourism decision support system will help the tourism destination managers set up the concept of tourism process, and provide them with important basis in forecasting tourism situations and guiding Chinese tourists in a reasonable and reliable manner. Users can set his/her preferences of the category and format of the data. For example, a restaurant manager, who wants to introduce new menu items to attract more Chinese tourists, would probably be interested in Chinese tourists’ preferences in terms of food taste and price category. He can select the relevant data in his city and display the data in a distributed pie chart.
In order to study in more depth and provide additional evidence for our results, we also include the validation stages in our framework. The validation stage mainly consists of individual interviews and focus group interviews. More specifically, individual interviews with key person such as tourist agency managers and potential partners can help to understand Chinese consumers’ behavior and trend, and focus group interviews with Chinese consumers can be conducted to explore their motivations and expectation (for consumers who have not visited Switzerland), and experiences (for consumers who have visited Switzerland).
Individual interviews. To capture Chinese consumers’ behavior and trend, a survey procedure that focus on the depth and richness of interview data should be designed to encourage free expressions of interviewees’ thoughts and feelings. The main target groups of the individual interviews are managers in tourist agencies and potential partners in tourism or related industries,
Focus group interviews. Since Chinese consumers’ motivations and expectation (for consumers who have not visited Switzerland), and experiences (for consumers who have visited Switzerland) of visiting Switzerland have not been studied extensively, to elicit an in-depth understanding of the issues and provide a solid base for further relevant instrument construction, a focus group method is thought to be appropriate as it can offer researchers opportunities to garner substantive information about participants’ thoughts and feelings on the topic of interest in a relatively short period of time [
This paper proposed a framework towards a tourism decision making support system platform by adopting linked data approach. It described a use case of the usage of tourism data from Sina Weibo on Chinese tourists in Switzerland, and thus provided evidence on how semantic web technology-based linked data can be used to manage tourism data to support decision making.
This study filled an important gap in the literature on Chinese consumer behavior in Switzerland based on social media platforms. To date, little is known about the tourism-related UGC from the Chinese social media platform Sina Weibo. This research work would serve a first step toward a better understanding in this regards.
Future research should follow the proposed framework by employing real tourism data in Sina Weibo. With a large amount of text messages in Sina Weibo and intensive analyses, the results will allow a comprehensive view of how Chinese tourists perceive Switzerland and their preferences regarding products and services. Such understanding includes identifying Chinese tourists’ favorite visiting place, determining factors that influence travel decisions, measuring satisfactions of tourism activities performance and recognizing new opportunities.
