A Study On The Formalized Description Of The Event Semantics In E-commerce Domain

E-commerce is a significant commercial pattern in the mobile Internet era and the intelligentialization of E-commerce has been an inexorable direction of the development of its technology and application. The realization of its intelligentialization involves various theories and techniques among which intellective semantic computing ranks one of the most tricking and crucial questions.Being a new theory introduced into the processing of natural language processing, event semantics has shed some light on discourse semantic analysis. The understanding of events and the elements in event structures lays the foundation for semantic analysis, while the concrete application of event semantic analysis is the embodiment of the value of natural language processing. Nowadays, the domestic and international studies of semantic analysis and its applications are still under exploration. Based on event semantics, this dissertation constructs a template bank for the formalized description of the core events in E-commerce by defining the template of event description, which aims at providing the theoretical foundation and resource for the realization of the intellective semantic computation in E-commerce.The dissertation consists of six chapters and the main ideas for each chapter are as below:Chapter 1:Introduction. This chapter briefly introduces the research background, objects, contents and its significance. By analyzing the overall development of E-commerce and its future trends, the significance of semantic computation for the intelligentialization of E-commerce is illustrated.Chapter 2:An Overview of Event Semantics Research. This chapter sorts out both domestic and overseas research situation of event semantics and discusses the limitation of the research findings for semantic computation. Furthermore, it also expounds the research methods and application value of field event semantics in processing natural language.Chapter 3:Event Elements and Event Structure Description. From the perspective of semantic attributes, this chapter thoroughly analyzes the connotation and denotation of events in order to make definition and classification of them as well as elaborates the feature of each event category. According to the changes of state and the involved participants, as well as the meaning in specific context, events are divided into two structure patterns (simple event and complex event), four semantic types (time-oriented event, space-oriented event, time-space dual-relevant event and time-space free event) and two aspect patterns (processing event and resultative event). By analyzing the semantic structures, six basic elements are extracted, namely event body, participant, time, space, number and situation. Based on the six primary elements,25 sub-elements are further defined. These elements as a whole lay the basis of the general event description templates.Chapter 4:The Construction of the Event Ontology in E-commerce Domain. Referring to the common approach of ontology construction, this chapter discusses the methods and procedures to construct event ontology in E-commerce with emphasis on the conception construct of the core events.1066 event concepts are extracted from the specialized dictionaries, online resources, and the corpus of real business transactions. These concepts are further classified and stratified according to the transaction process and the technologies in E-commerce, and thus to construct the concept system of essential events in E-commerce. The system consists of three levels, the first level includes 5 categories of events, information flow events, logistics events, capital flow events, synthetic events and general events; the second level includes 25 subcategories and the third level covers 453 synsets, i.e. conceptual nodes.Chapter 5:Semantic Description of the Core Events in E-commerce. In this chapter, some of the core events in E-commerce selected from the basic concepts list, the scope and semantic elements of each event category are analyzed. By using the universal six-tuple template, core concepts in E-commerce are made a detailed formalized description and thus the event template bank in E-commerce is constructed.Chapter 6:Conclusion and Outlook. The achievements and limitations of this research are concluded, and the outlook for further research is also remarked.
