    With the increasing popularity of the Semantic Web, more and more data becomes available in RDF with SPARQL as a query language. Data sets, however, can become too big to be managed and queried on a single server in a scalable way. Existing distributed RDF stores approach this problem using data partitioning, aiming at limiting the communication between servers and exploiting parallelism. This pap... View full abstract»

    Schema mapping is becoming pervasive in information integration through data exchange and data integration. In this paper, we show that current schema mapping generation and verification techniques are not capable of reconciling some semantic heterogeneity because of ambiguities in interpreting different types of relations. To address this problem, we enrich the mapping generation process using co... View full abstract»

    The Web is witnessing an exponential growth of increasingly complex, distributed and heterogeneous documents. This hampers document exchange, as well as their annotation and retrieval. While information retrieval mechanisms concentrate on textual features (corpus analysis), annotation approaches either target specific formats or require that a document follows interoperable standards. This work pr... View full abstract»

  • Automated educated guessing

    Publication Year: 2013, Page(s):19 - 20
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (114 KB) | HTML iconHTML

    We describe the vision of a system that performs “educated guessing” to answer ad hoc information needs in case of missing or undisclosed information. The guessing procedure is based on discovered common patterns, obtained from structured and semi-structured data, guided by the specific information need. View full abstract»

    The Web of Data refers to the universal database constituted by interlinked data sources on the Web. This global system is creating a new way of publishing and consuming data on the Web. A number of assumption that were valid in bounded, controlled, closed worlds of data are now being challenged. In this paper, following the seminal ideas presented in 1994 by Peter Deutsch and later completed by J... View full abstract»

    Modern enterprise applications are a challenge for traditional database systems. In the recent years, enterprise workloads evolved from simple lookups and updates to complex queries integrating both analytical and transactional data. In addition, graph structures and queries today need to be integrated for applications like materials requirements planning, which add some further complexity to the ... View full abstract»

  • A vision for SPARQL multi-query optimization on MapReduce

    Publication Year: 2013, Page(s):25 - 26

    MapReduce has emerged as a key component of large scale data analysis in the cloud. However, it presents challenges for SPARQL query processing because of the absence of traditional join optimization machinery like statistics, indexes and techniques for translation of join-intensive workloads to efficient MapReduce workflows. Further, MapReduce is primarily a batch processing paradigm. Therefore, ... View full abstract»

    Large scale environmental knowledge integration and development of a knowledge recommendation system for the Linked Open Data Cloud using semantic machine learning approach was the main mission of this research. This study considered five different environmental big data sources including SILO, AWAP, ASRIS, MODIS and CosmOz complementary for knowledge integration. Unsupervised clustering technique...

    The benchmarking of databases is an involved topic to which cloud computing adds another level of complexity. For example, benchmarking of multi-tenant on-demand applications requires modeling tenants' dynamic behavior over time. This paper provides two methodologies for simulating realistic tenant behavior in enterprise on-demand scenarios. The methods cover the cases that no or not enough real-w... View full abstract»

    We introduce Ensemble, a runtime framework and associated tools for building query latency models on-the-fly. These dynamic performance models can be used to support complex, highly dimensional resource allocation, and/or what-if performance inquiry in modern database environments, such as data centers and Clouds. Ensemble combines simple, partially specified, lower-dimensionality models to provid... View full abstract»

    Recurring queries or partial queries occur very frequently in production workloads. Reusing results or intermediates presents a highly intuitive opportunity for performance enhancements and has been explored to various degrees. Strategies suggested so far in the literature depend largely on speculative materialization of results in the hopes that they can be reused later on. However, a materializa... View full abstract»
