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...
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...
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...
This paper describes the design and implementation of scientific knowledge output management based on institutional repository in Chinese Academy of Sciences. The aim, general function of institutional repository, plan, policy and sustainable supporting mechanism of scientific knowledge output management, the development of federated institutional repositories network based on OAI-harvester and the...
Grid_GIS is an SOA (service-oriented architecture) based grid GIS system for data and function sharing in multiple application domains. The Grid_GIS adopts a Super P2P (peer-to-peer) architecture to realize the distributed storage, query processing and dynamic integration of data and functions resources. The domain ontology knowledge and reasoning rules are used to support the semantics-based intelligent...
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....
Service-oriented computing (SOC) is the computing paradigm that utilizes services as fundamental elements for developing applications. The modeling and analysis of services-oriented software requirements is one of important study contents in SOC. Owing to frequent changes of individual or collective requirements, continuous evolution of system function and structure, the study object of services-oriented...
Tools are very important for aircraft engine design and making, the trend is implementing knowledge management. On the basis of the analyzing tools design in nowadays, aimed at problems in them, present a model of design knowledge based on the ontology, its knowledge management routine and technology system. Presented framework to support this system.
Service-oriented computing (SOC) is a kind of computing paradigm that utilizes services as fundamental elements for developing applications. In study domain of SOC, modeling and analysis of services-oriented software requirements is an important research direction. Because of frequent changes of individual or collective requirements and continuous evolution of system function & structure, the...
The development and maintenance of domain knowledge based system need a lot of manual operations, and with the increasing amount of contents in the system, it is more and more difficult to find the relevant information. The keyword based search usually can not return the accurate result. To solve these problems, this paper proposes a semantic knowledge system with ontology engineering approach. It...
Spatial information retrieval which is mainly catalog service based on metadata is the foundation of spatial information sharing. Today's information retrieval methods in catalog service are typically limited to keyword searches or matches of sub-strings, which do not meet user's retrieval demand. This paper presents a semantic similarity degree algorithm, in which geo-ontology is compared from concept...
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 keyword matching, which can not fully take advantage of the information context and potential knowledge. All of these methods are particularly inefficient as to geospatial information which is more...
Networked software (NS) is a service-oriented software application that is accessed via human-network interaction equipments. Owing to the characteristics(such as uncertainty, incompleteness, and evolution) of NS requirements, the requirements engineering face challenges in requirements elicitation. This paper proposes a requirements elicitation approach for networked software that builds a bridge...
Ontology is adopted as a standard for knowledge representation on the semantic Web, and resource description framework (RDF) is used to add structure and meaning to Web applications. In order to incorporate fuzzy systems into the Semantic Web, this paper utilizes fuzzy ontology to represent formally the fuzzy linguistic variables, considering the semantic relationships between fuzzy concepts. Then...
