Web development shows itself in the e-learning environment. Developments in the e-learning environment are expected to provide high motivation, cooperative and more constructive experiences for students. In terms of being able to provide convenience in technological harmonization process which is in need of professionalism, programming skills are also included in today's needs. E-learning environments...
Currently there is a large amount of material for support educational processes in different areas, specifically in the area of programming fundamentals, it is useful to give the students tutorials, videos, solved exercises and source code as support for their learning process. The problem associated with this is that often the given objects don't match with the student's learning style. In this article...
This article contributes to the development of Linked Open Government Data in Romania. Through a number of information retrieval and natural language processing techniques and with the use of a number of Web 2.0 APIs we process the semi structured data offered by data.gov.ro regarding Romanian companies, turning it into semantic data and linking it to other processed data on opendata.cs.pub.ro. Afterwards...
Linked data mining has become one of the key questions in HPC graph mining in recent years. However, the existing RDF database engines are not scalable and are less reliable in heterogeneous clouds. In this paper we describe the design and implementation of Acacia-RDF which is a scalable distributed RDF graph database engine developed with X10 programming language to solve this issue. Acacia-RDF partitions...
We introduce a framework to extract and parse Java source code, serialize it into RDF triples by applying an appropriate ontology and then analyze the resulting structured code information by using standard SPARQL queries. We present our experiments on a sample of 134 Java repositories collected from Github, obtaining 17 Million triples about methods, input and output types, comments, and other source...
Security is one of the main issues in all phases of the software life cycle. Since most software vulnerabilities occur in coding phase, so the secure implementation is very important. Semantic Web ontology expresses the concept of a specific area. According to variety of software systems and manufacturing techniques, the Semantic Web can be effective in production of software systems. Anthology helps...
In Linked Data, owl:sameAs predicate is used for linking different datasets. However, there are reservations about its use and its role in linking data. In linking different datasets, owl:sameAs can lead to violation of the strict identity semantics of this predicate, because it is symmetric and transitive, meaning that anyone can link their data with your dataset, from anywhere. Consequently, the...
As an RDF representation of information extracted from Wikipedia, DBpedia has been serving as an interlinking hub for many other RDF data sets in the Linked Open Data cloud on the Web of Data. Therefore, accessing the DBpedia data set is a common task for various Semantic Web applications. Given the fact that DBpedia is currently accessed through public SPARQL endpoints, which requires the users to...
This paper proposes an extension to the Ontology of the Brazilian Federal Budget, available today as Open Data, in order to integrate to this ontology geolocation concepts that enable decision making in the budgetary field, considering the regional characteristics of the country. The proposed extension involves the transformation of relational data representing locators which are key elements of the...
This paper analyzes the potential of Semantic Web technologies to support innovation in industrial scenarios. The study focuses in particular on RDF stores, the software components dedicated to the storage, representation and retrieval of semantic information. Starting from a literature review, a qualitative analysis is carried out considering a set of these systems. RDF stores are evaluated to find...
Nowadays, semantic web technology depends on interexchange and integration of RDF data for various aspects of each social communication. The searching for possible answer to the related topics across the open data source obviously becomes a massive task. In this research, we study the RDF query with parallel processing on the GPU. In particular, in this paper, we consider the compact data representation...
If the World Wide Web is taken as a mountain of information containing data regarding every aspect of life, then Semantic Web is its extended version, that structures the information and makes it machine process able. Semantic Web has many advantages which have proved it as an innovative approach to structure the data for multipurpose domains. Its characteristics of annotation enable the extraction...
RDB2RDF mapping has been a hot topic in the Semantic Web research community. In order to standardize the mapping mechanism and then facilitate sharing and reuse of the mapping definitions, the W3C RDB2RDF Working Group published a general purpose RDB2RDF mapping language standard, R2RML, in September 2012. Several mapping tools or ongoing projects have been gradually supporting the R2RML standard...
Structurally, the Web resembles a marketplace: Web clients download documents from servers just like customers buy goods from kiosks. Interestingly, the marketplace metaphor for the Web goes further: most Web users are in the role of the customer and the documents downloaded in most cases actually represent commercial offers. This second resemblance leads to a fundamental asymmetry: in general, commercial...
The RDF framework is the underpinning element of Semantic Web stack, its widespread adoption requires efficient tools to store and query RDF data. A number of efficient local RDF stores already exist, while distributed indexing and distributed query processing are only starting to develop, furthermore dynamically growing and fail-safe solutions are not yet available. To remedy this situation, we propose...
Resource Description Framework (RDF) is commonly used for the semantic web query. During this decade, due to big data processing, the large numbers of RDF triples are crawled. The triples usually stored distributed on the clouds storage or the large clusters. To search for the query answer, it is usually difficult to handle the search across platforms. Also, the search takes a long executed time....
A storage service implementation, based on a semantic content repository of Tupelo is designed and developed. The architecture of the implementation makes it possible to accommodate both bitstream and metadata storage. The mapping solution from the digital library entities and their relations to the counterparts with semantic data structure is also provided. A case study on an open source digital...
Design patterns provide experience reusability and increase quality of object oriented designs. Knowing which design patterns are implemented in a software is important in comprehending, maintaining and refactoring its design. However, despite the interest in using design patterns, traditionally, their usage is not explicitly documented. Therefore, a method is required to reveal this information from...
Software developers use various software repositories in order to interact with each other or to solve software related problems. They are required to adopt an identity for each of the software repositories they wanted to use. Quite often developers are also found on different code forges developing open source projects. It is worth mentioning that the information relevant to the developers are distributed...
Reliable and secure management of data collected from remotely deployed sensors is critical to the operational success of any sensor deployment. The Remote Deployment Framework (RDF) is a general purpose framework design based on a service oriented architecture and implemented using Java enterprise technologies. The framework supports the collection and transportation of data from sensors which have...
