“…By excluding individuals with previous experience, the outperformance of the test group becomes even more evident beneficial, compared to their colleagues using a traditional search engine. This finding is similar to (García-González et al 2017), in which the test group could benefit from a similar scaffolding support provided in the Sakai LMS. The choice of excluding subjects with prior knowledge is valid, as the experiment was explicitly aimed at subjects without prior knowledge.…”

The ever-growing amount of learning material poses a challenge to both learners and teachers. In order to perform a learning task, students often need to search for additional information. Inquiry might be hampered if they do not know what exactly to search for, especially if they lack prior knowledge in a domain. Furthermore, they might need to recall meta-information, e.g., the implicit links between learning resources or the location of an explanation within a document. In addition, their performance in a learning task might suffer from the constant need for further information. As the authoring of learning material is a time-intensive task, reusability of resources in different contexts should be enabled. In this paper, we present the ALMA-Yactul ecosystem, a holistic approach for student-centered integration of learning material. Based on semantic annotations, learners are provided with scaffolding support for retrieving material related to their current study task. This integration of resources is showcased in a variety of applications and domains, such as a plugin for an IDE or an enhanced sketchnoting app. Moreover, we show how Yactul, a gamified student response platform, can benefit from semantic annotations and integration of learning material. Additionally, teachers are provided with semi-automatic annotation support in the popular Office 365 suite to foster the reusability of their content. Apart from presenting the results of its usage in university classes, we also show how high school students without prior knowledge benefitted from this scaffolding support. A significantly better performance in resolving programming-related tasks could be observed compared to a traditional search process. Finally, the ecosystem is evaluated against a state-of-the-art technology integration model.

“…Recent Developments in e-learning interoperability standards, learning design and other research on the pedagogy of semantic e-learning have presented an inclination of Semantic Web technologies to encourage learning services focused on the learning content aware services and personalized [10][11][12]. Technologies based on ontologies and intelligent agents should support the processing of semantic information on the Semantic Web [13].…”

E-learning is a very dynamic field, constantly growing, which refers to an educa-tional content or learning experiences provided or made by means of digital tech-nologies. The development of this area has a direct impact on the quality of edu-cation and cost reduction. E-learning is now dominated by learning management systems such as Moo-dle, to improve the interoperability of these systems; the use of data / resources is a major requirement, this need to push the e-Learning community to seek new approaches to improve this interoperability of systems. On the other hand, se-mantic Web technologies offers standards like RDF allows to describe Web re-sources with their metadata. We propose in this work an approach based on Se-mantic Web technology to improve the interoperability of e-Learning systems like Moodle.

“…Herminio García-González, José Emilio Labra Gayo and MPuerto Paule-Ruiz [5] have described a new educational tool that relies on semantic Web technologies to teach text content.A research review related to the belief in the virtual world and semantic Web based on social network analysis has been reviewed in [6]. Largescale data has been analyzed within a virtual world by exploring the flow of trust in different layers of social networks with the help of Semantic Webtechnologies.The problem of knowledge base has been studies using semantic integration with crowd intelligence [7].The authors have proposed a hybrid framework for KB semantic integration considering the semantic heterogeneity of KB class structures.In [8], a method has been proposed by matching the semantic service based on word embedding thatimproves the efficiency of the service discovery.Two types of semantic services such as event-recognition and event-handling services are specified about the events and the words are matched through the evaluation of equality which is organized with word embedding.The framework has been proposed for effective search of suitable services by including information from social media [9].…”

In today's modern era, the Semantic Web is progressing at a tremendous speed. The Semantic Web services have opened new possibilities through which any one can avail various services. But if these technologies are not properly protected, then their use can put users in danger. Many people have to face difficulty in assessing the security hazards allied with Semantic Web services. Many Web services such as e-commerce stores various types of data on their database servers. These database servers are distributed across the globe. The e-commerce may use the unalike assortments of database for storing different information. Web services such as e-commerce have to handle assorted types of data. Unalike Web services like e-commerce have to handle assorted types of data. A single database program will not be suitable for storing and processing mixed types of data as it will increase the processing overhead and ultimately reduce the performance of the web service. So there is need arises to define an apposite subclass of databases for each document type.This paper insinuates a set of databases for each type of documents stored on an e-commerce platform. An exertion has been made to define a proper set of database programs for a web service such as e-commerce that adequately manages the requirements of a particular type of data. The tryouts have been steered for an e-commerce Web service for weighing the efficacy of the proposed approach. The results shows that if wellstructured database has been used for a Web service such as ecommerce then response can be very quick and chances of packet loss will also be very low. If network attacks such as DoS and man-in-the-middle attack exist within the request, the performance of the Web service severely affected. A network attack may lead to the more chances of packet loss. The paper also delineates the impact of network attacks on web service performance
