Review on inferential situation models

This paper reviews the theories and studies in the field of inferential situation models. The Construction-Integration （CI） model, the Structure Building Framework （SBF） and 3 empirical studies are introduced. The paper concludes that future studies, from a quantitative approach, should make some improvements in test materials, language proficiency manipulation and language background.

Sign and indexicality:a case study of enhancing alignment of situation models in SCWT

The story continuationwriting task(SCWT)is anewly emerging proficiency test of National Matriculation English Test(NMET)in three provinces in China.Nevertheless,little is known with respect to how test-takers enhance their alignment of situation models in SCWT.This paper reports on a case study of the development of situational alignment of one L2(second language)learner in a senior high school in Jiangsu Province,China,drawing on qualitative data collected via individual faceto-face interviews,and supplemented by face-to-face conversations and email exchanges,over a period of one year.This study investigates how the test-taker enhances her alignment of situation models,and what factors contribute to her development of situational alignment under the framework of a new semiotic research finding,a pan-indexicality model.This paper concludes that test-takers possess the capacity of developing their alignment of situation models,and that a pan-indexicality model,affording opportunities for test-takers to accurately decode the meaning of a linguistic sign at the overall sense level,plays a decisive role in identifying and integrating key dimensions of situation models and eventually enhancing test-takers’situational alignment.This study suggests that a pan-indexicality model can be employed by test-takers to understand the meaning of a linguistic sign at the overall sense level,and test-takers’encyclopedic knowledge,contextual information,and personal emotions regarding a linguistic sign should be highlighted in classroom instruction to help test-takers construct aligned situation models in SCWT.

An Emergency Scenario Reconstruction System Based on ESMM Event Situation Model

In order to keep decision-makers better informed with emergencies, it is useful to retrieve the user-oriented disaster relevant event information in an aggregated results list through meta-search engine. However, emergent event is dynamic which makes it difficult to use fixed search word or word combinations. This paper proposes an event situation monitoring model（ESMM） event detection model, which realizes heuristic query word vector dynamic expanding by adopting emergency fuzzy scenario reasoning ontology cluster. Disaster event facet information automatic searching is discussed as an example in this paper. The experimental results show that the proposed method can increase accuracy and extra clues not supplied by commercial search engines, which can be used as a supplement information source for government and individuals.

On-Demand Service in Cloud Computing

Cloud computing provides a new paradigm for hardware and software infrastructure design as well as planning and usage of information systems. It offers flexible, efficient, inexpensive, and quality services. This paper proposes an on-demand service system using the cloud computing architecture and analyzes important issues such as organization, management, and monitoring of distributed service resources; context-aware on-demand service modeling, on-demand automated service composition in large-scale networks, and service system analysis based on complex system theory. Continuous Operating Reference Station （CORS） of a geo-spatial information system is taken as an example, and its architecture is analyzed from the perspective of cloud computing. Some fundamental questions are raised about its service.

Design and Practice of Digital Value-Added in Jiaosi Hot Spring Tourism Industry

With an aim to promote the digital value-added design of local tourism, the study adopted Skilbeck＇s situational model to examine the promotion of local tourism through a digital value-added approach and integrated the design of APP： Tour Guide for Jiaoxi Hot Spring into the Study of Technology and Applications of Mobile Services and Augmented Reality for Cultural and Creative Industry and Tourism in Yilan. Through the development and demonstration of design, students are allowed to build and enhance their capacity for integration in addition to fulfilling university social responsibility （USR）. The study found that students used different methods in each phase to continuously absorb knowledge and discover problems and then propose creative solutions based on facts. By creating a mental map, students pondered promoting local tourism via digital value-added design and came up with a strategy of hot spring ＋ primary industry （agriculture ＋ aquaculture） tours, which integrated local gourmet, hot springs, religion, and the hot spring museum. Three routes are designed, namely Route 1： Hot Spring Park ＋ Aquaculture, Route 2： Tangweigou Hot Spring Park, and Route 3： Jiaoxi Old Street to make up the gap in the unilateral marketing of Jiaoxi Hot Spring. The study will further promote location-based services of the APP to fulfill the technology and applications of mobile services and augmented reality for local tourism.

Scientific Research Complex ＂BeOn-1＂ Performance Indicator of the Operators in Extreme Conditions

Complexity of the systems in everyday life of modern man continuously increases, as the monitoring and the management are concentrated on and depended on the reactions of one operator or a group of operators. Sometimes because of human errors in extreme situations, it increases the potential risk for life of large groups of people and of the operators. This requires continuous improvement of the systems for psycho-physiological assessment by developing the new efficient methods involving known and new indicators of psycho-physiological state of the individual. The complex BeOn-1 is a new computer-based experimental and applied system for examination of situational vigilance and behavior of aviation specialists-pilots, navigators, operators of unmanned aerial vehicles in a complex operating environment with extreme impact factors. In the up-to-date systems for evaluating the operators, the test results are compared and analyzed together with a number of physiological parameters that are used as indicators of psycho-physiological status of the investigated subjects. In the ＂BeOn-1＂ they are indicators about the efficiency of individual stress coping strategy. BeOn-I allows us to study the individual skills of perception and the ability to act under extreme conditions of the operational environment and is a comfortable working methodology for daily needs in the selection, periodic monitoring of the operational staff and support to flight safety.
