As the number of Web APIs is rapidly increasing, it is an urgent issue to discover qualified Web APIs and provide value-added services by orchestrating them. However, most of the interface descriptions of Web APIs are informal, and the Web API SLA contracts, which are a key to quality of services orchestration, require manual operations at the consumers. Meanwhile, applying the blockchain, the distributed...
In recent years, the potential benefits of reusing and analyzing the massive quantities of data have been discussed among various stakeholders from diverse domains. In order to take advantage of results of data analyses, instead of forcing to open or share data, it is important to activate a Market of Data, where users select data which they want, negotiate with data owners, and get data at reasonable...
We have developed a large semi-synthetic, semantically rich dataset, modeled after the medical record of a large medical institution. Using the highly diverse data.gov data repository and a multivariate data augmentation strategy, we can generate arbitrarily large semi-synthetic datasets which can be used to test new algorithms and computational platforms. The construction process and basic data characterization...
As the reasoning aspects and the knowledge based processing capabilities of RDF (Resource Description Framework) have been widely adopted in W3C Recommendation, the ontology layer and query languages of the Semantic Web stack achieve a certain level of maturity. There exists an increasing need for high performance, read-only semantic analysis for the massive RDF data. In this demo we will present...
Indexing is one of the important technique used to make searching and retrieval process more accurate and faster. In this paper, the indexing features of triple stores are investigated to see the pattern of semantic indexing that will improve the current information retrieval indexing. To do the evaluation, we choose the best triple stores, Allegro Graph. AllegroGraph require more than one triple...
The problem of processing XML streaming data fits a large class of new applications and has been a hot spot recently. The XML streams on the World Wide Web are usually autonomous, distributed and heterogeneity. All existing methods, however, do not support processing a collection of XML streams from heterogeneity data sources. In this paper, we address the heterogeneity issues in the context of XML...
