Ontology Model and Semantic Link Network (SLN) are two important semantic data models in Semantic Web. Ontology Model can describe network resource in concept space, while SLN can describe various links and relations between network resources. Combination of Ontology Model and SLN can help to improve the effect of network resource retrieval, but data transfer and exchange between ontological knowledge base and SLN knowledge base are needed. This paper presents semantic relationship tree (SRT) to realize the information transfer from Ontology Model to SLN, and also gives an example of network resource retrieval based on ontology knowledge base and SLN knowledge base.
本体模型(Ontology Model)和语义链路网络(Semantic Link Network, SLN)是语义Web中两个重要的语义数据模型。本体模型可以在概念空间中描述网络资源,而语言网络可以描述网络资源之间的各种联系和关系。本体模型与语言网络的结合有助于提高网络资源检索的效果,但需要本体知识库与语言网络知识库之间的数据传递和交换。本文提出了语义关系树(SRT)来实现本体模型到语言网络的信息传递,并给出了一个基于本体知识库和语言网络知识库的网络资源检索实例。

Labeled datasets are essential for text categorization. They are used to train a classifier, or as a benchmark collection to evaluate categorization algorithms. However, labeling a large-scale document set is extremely expensive because it involves much human labour, and the labeling process itself is subjective rather than objective. Therefore, labels assigned to documents by only one human editor in some existing labeled document sets may be of limited use and may prove problematic for training a classifier or evaluating categorization algorithms. This research explores socially constructed Web directory, the Open Directory Project (ODP), to generate a series of labeled document sets by extracting semantic characteristics from the ODP categories which are annotated by a list of indexed Websites. The generated document sets are used to classify Web search results and the results are encouraging.

Resource Space Model (RSM) is a semantic data model for specifying, organizing, and retrieving resources based on classification of resources. An efficient index mechanism is critical for its implementation. However, traditional index mechanisms are not well suitable to resource spaces because the spaces are discrete and hierarchical. This paper proposes a new multidimensional index structure C*-tree. It employs boxes to represent resources so that the containment of boxes can reflect the hierarchical structure of resources. The metric function defined in the C*-tree is able to gather close resources in the index structure. To avoid overlap between bounding boxes, a new restricted bounding box is further introduced. Moreover, the insertion algorithms based on the data partition approach can fully utilize characteristics of RSM. The C*-tree is scalable and efficient on both the number of dimension and the amount of data for different distributions.

Data gathering is a major function of many applications in wireless sensor networks (WSNs). In this paper, An Effective Data Gathering scheme for heterogeneous energy WSNs (EDGA) is proposed. EDGA achieves a good performance in terms of lifetime by minimizing energy consumption for in-network communications and balancing the energy load. EDGA adopt a simple but efficient method to solve the area coverage problem in a cluster range, namely intra-cluster coverage. Finally, the simulation results demonstrate that the proposed EDGA significantly outperforms LEACH, HEED in terms of network lifetime and the amount of data gathered in the heterogeneous energy network.

The proposal and development of semantic web make ontology, as a new knowledge organization and semantic description method, get attention in various fields. The building of ontology is a basic and important task in semantic web. The construction method and organizational structure of ontology will directly affect the application of ontology. Based on the analysis of hierarchical characters existing in domain knowledge representation and organization and also the process of ontology building, this paper puts forwards a hierarchical construction method of ontology and gives the hierarchical construction principles in different ontology levels, which pays much attention to the hierarchical relationships in every stage of ontology building. And then based on this hierarchical construction method, this paper designs and builds a three-level geographical ontology applied in spatial information service. And also, this paper presents a description mechanism of ontology class metainformation to extend the description capability of OWL, which can help to well represent the difference and relationship between concept and term. The hierarchical identification in class meta-information can help to realize quick retrieving and matching of concepts based on hierarchical relationship.

Recently, the Storage Networking Industry Association (SNIA) has released the first standard for cloud interoperability. With more and more standards for interoperability emerging, it can be expected that a global cloud resource exchange market will form. In such a market, it is challenging to present a dynamic pricing scheme to meet different requirements. To cope with the challenge, in this paper we first present a framework for constructing global cloud resource markets and then propose a knowledge-based continuous double auction (CDA) model that determines the price of cloud resources using a learning algorithm based on historical trading information. Experimental result shows that our model can attain high market efficiency as well as stable trading price.

Semantic Link Network (SLN) consists of semantic nodes, semantic links between semantic nodes, and rules for reasoning. The semantic communities of SLN reflect not only the tightly knit structure but also different aspects of semantics embedded in SLN. Traditional community discovery approaches are not suitable for discovering semantic communities. This paper investigates an approach to discovering dynamic semantic communities by evaluating every semantic node and semantic link according to Semantic Reasoning Closure’s semantic importance, Semantic node’s structure value and Semantic node’s reasoning times.
