The availability of numerous sources of structured data on the Internet poses the problem of their integration into a unified information space just as the unstructured data and weakly structured data sources are integrated in the framework of the WWW. The main requirement for such an information space is the simplicity of operation for the users that are not trained IT experts. The architecture of a system of semantic integration of distributed and heterogeneous data sources is proposed in the framework of a unified semantic access interface. The semantic nature of this interface lies in the fact that one can interact with such a system in terms of the concepts of the application domain completely ignoring the implementation details of the systems being integrated. The proposed architecture simplifies the users' work, the integration process, and the development of user forms with a rich functionality including a semantic navigation between the forms. A distinctive feature of this architecture is that the system integration and the development of user forms are performed declaratively in the interactive mode without programming. The simplification of the users' work with the system is achieved due to some special properties of the semantically complete model (SCM) and of the semantically complete query language (SCQL), which provide a basis for the system. A prototype of the system under study is briefly described. The prototype is implemented as a type of the client-server technology based on the SCM-SCQL.

Aiming at the heterogeneity of data sources in marine disciplines, this article uses XML technology for integration to achieve a unified representation of marine data. At the same time, it is supported by J2EE technology to propose and implement a multi-layer B/S architecture for marine XML data integration. The system prototype uses the scalable vector graphics (SVG) technology, an emerging XML technology, to realize the interaction of ocean data based on XML and provide support for ocean informatization.

Open environment allows agents to associate and/or dissociate with the environment without affecting the overall functionality of the system. There are several challenges to modeling data integration systems (DIS) in open environment. This is because of the distributed, dynamic, heterogeneous, and loosely coupled nature of open environment. It is also important to note that information systems are intensional in nature. This is because the belief of an agent and the knowledge of an information system are intensional contexts. Open environments are also intensional in nature. This is because, the dynamic nature of open environment imposes no constrains on the set of participating agents or the number information systems plugged into the system. We propose the use of Mediated P2P architecture for the architecture of data integration systems in open environment. The DIS is formulated using Intensional Epistemic Logic (IEL). We also present an interface and query answering semantics that are based on the IEL. The proposed model accounts for the intensional, distributed, dynamic, and loosely-coupled characteristics of open environment.

In digital library federation, a challenge is how to exchange and share information on heterogeneous digital libraries. The mediator-based approach of data integration provide a uniform view by creating the semantic relationship between sources and mediated schema. Since automatic matching produce probabilities, it's necessary to take the probability of mappings into consideration. Further more, for tuples' probabilities arise as an additional ranking dimension, both tuple probabilities and scores be factored in the interpretation of top-k queries in probabilistic databases. In this paper, after proposing a architecture of data integration for DLF, we demonstrate the probabilities for the schema mappings and query answerings. Then, having discussed the opt_U-kRank algorithm, we describe the revised_U-kRank algorithm which may improve the efficiency of execution. Finally, based on the experiment results of two U-kRank algorithms, we discuss the effect of probabilities distribution on executions.

Background: Amines are biogenic amino acid derivatives, which play pleiotropic and very important yet complex roles in animal physiology. For many other relevant biomolecules, biochemical and molecular data are being accumulated, which need to be integrated in order to be effective in the advance of biological knowledge in the field. For this purpose, a multidisciplinary group has started an ontology-based system named the Amine system Project (ASP) for which amine-related information is the validation bench. Results: In this paper, we describe the Ontology-Based Mediator developed in the Amine system Project (http://***) using the infrastructure of Semantic Directories, and how this system has been used to solve a case related to amine metabolism-related protein structures. Conclusions: This infrastructure is used to publish and manage not only ontologies and their relationships, but also metadata relating to the resources committed with the ontologies. The system developed is available at http://***/WebMediator.

Background: Saccharomyces cerevisiae is recognized as a model system representing a simple eukaryote whose genome can be easily manipulated. Information solicited by scientists on its biological entities (Proteins, Genes, RNAs...) is scattered within several data sources like SGD, Yeastract, CYGD-MIPS, BioGrid, PhosphoGrid, etc. Because of the heterogeneity of these sources, querying them separately and then manually combining the returned results is a complex and time-consuming task for biologists most of whom are not bioinformatics expert. It also reduces and limits the use that can be made on the available data. Results: To provide transparent and simultaneous access to yeast sources, we have developed YeastMed: an XML and mediator-based system. In this paper, we present our approach in developing this system which takes advantage of SB-KOM to perform the query transformation needed and a set of data Services to reach the integrated data sources. The system is composed of a set of modules that depend heavily on XML and Semantic Web technologies. User queries are expressed in terms of a domain ontology through a simple form-based web interface. Conclusions: YeastMed is the first mediation-based system specific for integrating yeast data sources. It was conceived mainly to help biologists to find simultaneously relevant data from multiple data sources. It has a biologist-friendly interface easy to use. The system is available at http://***/yeastmed/.

Online Ordering of Overlapping data Sources

PROCEEDINGS OF THE VLDB ENDOWMENT 2013年第3期7卷 133-144页

data integration systems offer a uniform interface for querying a large number of autonomous and heterogeneous data sources. Ideally, answers are returned as sources are queried and the answer list is updated as more answers arrive. Choosing a good ordering in which the sources are queried is critical for increasing the rate at which answers are returned. However, this problem is challenging since we often do not have complete or precise statistics of the sources, such as their coverage and overlap. It is further exacerbated in the Big data era, which is witnessing two trends in Deep-Web data: first, obtaining a full coverage of data in a particular domain often requires extracting data from thousands of sources;second, there is often a big variation in overlap between different data sources. In this paper we present OASIS, an Online query Answering system for overlappIng Sources. OASIS has three key components for source ordering. First, the Overlap Estimation component estimates overlaps between sources according to available statistics under the Maximum Entropy principle. Second, the Source Ordering component orders the sources according to the new contribution they are expected to provide, and adjusts the ordering based on statistics collected during query answering. Third, the Statistics Enrichment component selects critical missing statistics to enrich at runtime. Experimental results on both real and synthetic data show high efficiency and scalability of our algorithm.
