基于问题域的领域模型库度量
在网络化软件中,为了便利地对领域建模所得到的巨量、多粒度、多层次的领域模型进行复用,从而实现按需服务,需要以问题域为单位对领域模型进行组织.为此,以领域问题域的内聚度和耦合度为指标,对问题域的划分合理性进行度量,基于该度...

基于地理信息系统的湖北省主要旅游景区可视化信息发布研究被引量:2
2009年
以Google Earth软件作为基础GIS平台,通过kml标记语言,制作并加载湖北省主要旅游景区的地标,然后对旅游景区最新信息用文字、图片、视频等通过HTML等文件在GE平台上进行发布,该方法可将传统二维的复杂旅游信息系统模式转换为一目了然、立体显示的旅游信息平台,支持影像数据更新和成果网络共享,既便于政府决策管理又方便公众及时掌握信息,有一定的研究价值和广阔的应用前景。

Discovering Protein Complexes from Protein-Protein Interaction Data by Dense Subgraph
2011年
High-throughput techniques,such as the yeast-two-hybrid system,produce mass protein-protein interaction data. The new technique makes it possible to predict protein complexes by com-putation. A novel method,named DSDA,has been put forward to predict protein complexes via dense subgraph because the proteins among a protein complex have a much tighter relation among them than with others. This method chooses a node with its neighbors to form the initial subgraph,and chooses a node which has the tightest relation with the subgraph according to greedy strategy,then the chosen node is added into the initial subgraph until the subgraph density is below the threshold value. The ob-tained subgraph is then removed from the network and the process continues until no subgraph can be detected. Compared with other algorithms,DSDA can predict not only non-overlap protein com-plexes but also overlap protein complexes. The experiment results show that DSDA predict as many protein complexes as possible. And in Y78K network the accuracy of DSDA is as twice times as that of RNSC and MCL.

Trustworthy Assurance of Service Interoperation in Cloud Environment被引量:6
2011年
Cloud computing can be realized by service interoperation and its essence is to provide cloud services through network. The development of effective methods to assure the trustworthiness of service interoperation in cloud environment is a very important problem. The essence of cloud security is trust and trust management. Combining quality of service (QoS) with trust model, this paper constructs a QoS-aware and quantitative trust-model that consists of initial trust value, direct trust value, and recommendatory trust value of service, making the provision, discovery, and aggregation of cloud services trustworthy. Hence, it can assure trustworthiness of service interoperation between users and services or among services in cloud environment. At the same time, based on this model, service discovery method based on QoS-aware and quantitative trust-model (TQoS-WSD) is proposed, which makes a solid trust relationship among service requestor, service provider and service recommender, and users can find trustworthy service whose total evaluation value is higher. Corapared to QoS-based service discovery (QoS-WSD) method, it is proved by the experiment for TQoS-WSD method that more accurate result of service discovery will be achieved by service requestor, while reasonable time cost is increased. Meanwhile, TQoS-WSD method strongly resists the effect of service discovery by untrustworthy QoS values and improves service invocation success-rate and thus assures trustworthiness of services interoperation.

KMP算法在Web服务语义标注中的应用
对Web服务进行语义标注是指基于领域本体对Web服务进行语义描述,使其能够被计算机所理解,因此标注算法的优劣直接会影响到Web服务标注的准确率.目前人工标注方法繁琐,而全自动标注方法又无法保证其准确性,因此研究半自动语义...
