Ontologies play an increasingly important role in emergency domain. They have become essential components of emergency response system. Development of emergency ontology is a laborious and difficult task because of the increasingly scale and complexity of the ontology. This paper proposes the concept of Event Ontology Pattern (EOP) and the development method of EOP, which is to capture formally reoccurring...
Knowledge representation is a strategy which represents the human knowledge as the data structure and the system control structure that can be processed by computer. As a knowledge representation method, domain ontology can represent the specific knowledge of a specific area. In the design of skill knowledge base, it will involve a lot of corresponding events to skills, and the knowledge contained...
Due to the disadvantage of the word segmentation tool in the aspect of the accuracy of word segmentation and speech tagging, it has harmful effects to the further research work. So this paper proposes a method based on the results of word segmentation to utilize language rules, which has been defined and described in Event Ontology, to verify and correct them. Experimental results show that compared...
Aiming at the software engineering practice of undergraduate, this paper proposes a software development practice platform. This platform effectively combines teaching management with software development process management, and realizes a complete lifecycle management of software engineering practice. As well, based on event ontology, this platform constructs a knowledge base of teaching resources...
Exchange of event information among multiple interconnected power system operators has become imperative for integrated and secure operation of the system. Considerable literature is reported on the standardization of power system data, while limited work has been done on the standardization of events. In this paper, we define a high level event ontology for power systems comprising seven concepts,...
For the difference between the traditional ontology and event ontology, this paper proposes a new event ontology storage mode and implements an event ontology system to manage the event ontology. The experiments show that the proposed mode has a higher query efficiency and lower data redundancy comparing to the XML storage mode. In addition, the new storage mode can preserve integrate semantic information...
Along with the rapid popularity of the Internet, crime information on the web is becoming increasingly rampant, and the majority of them are in the form of text. Because a lot of crime information in documents is described through events, event-based semantic technology can be used to study the patterns and trends of web-oriented crimes. In our research project on cyber crime mining, we construct...
In reservoir engineering domain experts deal with many tasks and operations, ranging from reservoir simulation to well maintenance scheduling, with the goal of maximizing oil production. These operations involve different applications, and generate a large number of events at the time of their execution. Understanding these events and the relationships among them can aid the domain experts in decision...
In this article, we are presenting a series of ontology-driven mechanisms for system diagnosis. Mainly, we introduce an event ontology and concepts related to semantic tag clouds and show how to manage the activities to build an ontology-based diagnosis. We formalize these concepts in order to derive diagnosis actions and to validate the successful actions. We also propose an augmented action model...
Event as the unit of human knowledge, has attracted more and more attention and high regards from the academia. Events-based knowledge extraction and representation extend concept-based knowledge process techniques largely. In order to represent event-based knowledge, this paper extends existing web ontology language, OWL, by introducing some new constructors and axioms related to event features....
In recent years, more and more experts find that events have more semantic means than any other features, such as, characters, terms and concepts. This paper described a method which used event features to classify Chinese Web pages talking about personality in SVM classifier. Firstly, we explained how to represent Chinese documents by event features. Secondly, we constructed event ontology about...
A sensor networked environment is capable of observing real-world phenomena as sensor readings, however, there are difficulties in understanding real-world dasiaeventspsila such as activities of daily life occurring in the environment. We propose an incremental model for constructing real-world knowledge to allow us to understand real-world events. The central plank of the proposed model is the labeling...
