Because of the crisis of unexpected events, data sources are complex and diverse. The application of the phrase weight measurement technique and the network user free marking technology in large data technology, transform the multimodal crisis information into a single information source, An integrated model for the extraction of crisis information was established. The integrative course includes...
We describe a new educational tool that relies on Semantic Web technologies to enhance lessons content. We conducted an experiment with 32 students whose results demonstrate better performance when exposed to our tool in comparison with a plain native tool. Consequently, this prototype opens new possibilities in lessons content enhancement.
As the Linked Data paradigm is embraced by a growing number of data providers (and consumers), the count of publicly available, semantically-annotated resources is systematically increasing. Here, elasticity and extensibility of semantics, enmeshed in Linked Data principles, and technologies supporting them, starts to attract application developers. In this context, multitude of developed ontologies...
Program analysis is the process of gathering deeper insights about a source code and analysing them to resolve software problems of arbitrary complexity. The key challenge in program analysis is to keep it fast, precise and straightforward. This research focuses on three key objectives to achieve an efficient program analysis: (i) expressive data representation, (ii) optimised data structure and (iii)...
Data interoperability is a prerequisite to achieve cross-community and cross-application sharing of information and knowledge. Heterogeneous data from multiple sources including semantic and non-semantic data sources (e.g. SNS data, web data, relational data, RDF, XML, CSV, etc.) have an important effect for IoT service provisioning. The data are not in a same type or format always that requires to...
With the development of information technologies, a great amount of semantic data is being generated on the web. Consequently, finding efficient ways of accessing this data becomes more and more important. Question answering is a good compromise between intuitiveness and expressivity, which has attracted the attention of researchers from different communities. In this paper, we propose an intelligent...
The Semantic Data are built from triples, that contain subjects, predicates and objects. On the other hand we can consider the triples as edges. The subject and the object are the nodes and the predicate is the label of the edge. In this view the Semantic Data define a graph. This graph can be very large, because a Semantic Dataset contains millions of triples. To query this dataset we can use the...
Big data technologies are becoming widely used, not only for recording but also for analyzing human generated data. Indeed, the recent development in systems and technologies provided many areas with data processing technologies to extract meaningful information from massive amounts of data. A good example of areas where the generated data is voluminous is eLearning, e.g. Massive Open Online Courses...
Entity alignment is to link “equivalent” entities that denote the same object in the real world, which can be used to help promoting information integration and retrieval. Driven by the knowledge graph initiative, large amount of owl:sameAs links need to be established. Most of the existing entity alignment methods are based on the matching progress of schema pattern, and there are limitations in...
During the lifecycle of automated production systems (aPS) additional functionalities and evolutions are realized. As a consequence, control software of aPS becomes highly complex and hard to maintain, which rises the need for evaluating and improving the quality of the control software. Tools for assessing and analyzing the quality of control software are rare and mostly lack accessible platforms...
Modern warfare is mainly based on the joint operation of multiple armies, but there exists the phenomenon of information chimney in different armed services and it can hardly realize the information sharing in the existed command and control system. In this paper, a new method of battlefield target information sharing based on ontology is proposed. Firstly, the target detection information databases...
Variety of systems were developed based on the Internet of Things (IoT) concept including autonomous systems, which operate without human intervention. Development of such systems requires not only data from devices, but also interaction between these devices. It is necessary that one IoT-system could control other devices behavior. There are several problems related to that task including problem...
Current Web-based Services are highly heterogeneous not only on data but also with regard to service interaction. Despite their heterogeneity, composition of these services is required in order to achieve additional functionality. Semantic descriptions and composition algorithms for heterogeneous services have been recently proposed. However, existing techniques do not take the Publish/Subscribe paradigm...
At present, more and more government departments and organizations choose to open their own data to the outside world. Open data can expand the scope of data sharing and improve the use efficiency of digital resources. However, most of the open data presents massive, decentralized and heterogeneous characteristics that greatly limit the use of open data. Also, semantic interoperability between data...
Scientific research teams have immense valuable knowledge that need to be managed. Organizing scientific contributions of team members constitutes a major challenge for the monitoring of knowledge evolution, team member’s competences discovery, and facilitating information retrieval processes. However, performing manual annotations is often time consuming and labor-intensive task, especially in case...
The Web has become a necessary resource of daily use, the benefits it offers, being a source of knowledge, and collaboration giving rise to new initiatives such as linked data, whose purpose is link the data scattered through the Web through of semantic relationships between them. The propose of this article is show the improving, consumption, and visualization of linked data in the Web, in such a...
Archived collections of documents (like newspaper archives) serve as important information sources for historians, journalists, sociologists and other interested parties. Semantic Layers over such digital archives allow describing and publishing metadata and semantic information about the archived documents in a standard format (RDF), which in turn can be queried through a structured query language...
A Question Answering (QA) system backed by a comprehensive and up-to-date knowledge base would be appropriate for travellers to satisfy their information needs. In this paper, a complete QA system is presented. It has two main phases: question identification (Expected Answer Type (EAT) identification) and searching the knowledge base (KB) to find the answer to the classified question. In QA systems,...
In this paper, we overview some of the Semantic Web-related technologies and describe a cognitive knowledge structure for biographical knowledge representation based on OWL markup language, we call it BKOnto. We all know that information management is becoming an important part of digital world, ranging from the management of personal collections to the construction of diversified, distributed, semantic...
The paper outlines directions for further development of global IoT. In particular, it discusses steps supposed to unlock IoT potential to assist consumers in their day-to-day routines. For these purposes requirements for scalable model of interactions between IoT entities formulated and a particular model satisfying these requirements proposed, alternatives for distribution of intelligence across...
