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...
In the era of big data, massive educational resources are stored on the internet and mobile networks. However, most of these resources are heterogeneous and decentralized, they have different format. The resources are designed for humans to read and not understandable to the machine. Their low level sharing and reuse make them difficult to acquire. How to access the resources the users need quickly...
Event similarity computation in text plays a vital role in the research of event ontology and construction, reduction as well as expansion of event networks. Furthermore, it's the precondition for application of event-based knowledge system. Existing event similarity computation methods are merely suitable for event ontology. In this paper, a new method for event similarity computation in texts is...
Hemiparesis is the most common impairment after stroke, and the initial severity of hemiparesis had been the strongest predictor of neuromotor functional recovery level. However, the intervention response of stroke survivors does not always correlate with their initial level of impairment, which implies the existence of other factors that may significantly affect stroke survivors' recovery process...
In the era of information explosion, information retrieval has become a bottleneck in information sharing and integration. However currently, the existing information retrieval methods are mainly based on keywords matching, which can not fully take advantage of the information context and potential knowledge. Although in the later researches, Geo-ontology has been used to enrich geospatial objects...
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....
