A suite of standards known as the Semantic Web is transforming the Internet to a semantic graph rather than a graph of hypertext links. This paper will describe how various ideas and initiatives in artificial intelligence knowledge representation influenced its design. We begin with the seminal work by Alan Turing and Alonzo Church that led to the definition of Turing Machines, enabled digital computing, and provided the mathematical theory of computation which has been one of the determining factors for Artificial Intelligence knowledge representation. We then provide a brief history of artificial intelligence knowledge representation starting with groundbreaking researchers such as Newell and Simon, then to the first "AI boom" driven primarily by rule-based expert systems followed by major initiatives such as Cyc and the DARPA Knowledge Sharing Initiative. We will discuss how innovations from these initiatives affected standards that in turn led to the suite of standards known as the Semantic Web. We conclude with a brief overview of the most important issues currently facing those who wish to see widespread adoption of Semantic Web technology in industry.

This paper proposed design and implementation of trucks tracking system using GPS based on semantic web for vehicle tracking in real time. In-vehicle unit and a tracking server is used. The information is transmitted to tracking server using GSM/GPRS modem on GSM network by using SMS or using direct TCP/IP connection with tracking server through GPRS. The received SMS contain longitude and latitude that are used to locate the vehicle on the Google maps. Tracking server also has GSM/GPRS modem that receives vehicle location information via GSM network and stores this information in database. It has been explored that most of the GPS based tracking systems are user friendly, cost effective, reliable and can be easily validated through different experiments and simulations which means that tracking system will send notifications periodically to the main station about the current position of the vehicle . Moreover those tracking notifications (GPS) will be stored in the database for fut...

Graphical user interfaces design in software development process focuses on maximizing usability and the user's experience, in order to make the interaction for users easy, flexible and efficient. In this paper, we propose an approach for evaluating the usability satisfaction degree of a web-based system. The proposed method has been accomplished in two phases and implemented on an airlines website as a case study. In the first phase, a website usability test is implemented by a number of users, and then the results obtained are translated into charts for a final web-based system evaluation in the second phase. The results achieved were satisfactory, since the places where the weaknesses and gaps in the website are identified and recommended solutions to avoid them are drawn. The authenticity of the results have been confirmed by comparing them with user opinions acquired from a questionnaire, which proves the precision in which the website is rated.

The network based denial of service attacks (DoS) are still the big challenge to the researchers in the field of network security. This paper handles the popular DoS attack called TCP-SYN flood attack, and presents the design and implementation of an Artificial Immune system for Syn flood Detection, abbreviated by AISD, based on the Dendritic Cell Algorithm (DCA). The AISD system is able to detect the generated SYN flood attack and response to its generator in a real-time. Performance and accuracy of the system have been evaluated through five experiments. Results of the experiments showed the precision of intrusion detection process to the ratio of 100%, with a notable response speed, and this is shows the benefit and suitability of using artificial immune systems to the network security problems.

This paper describes the use of adaptation patterns in the task of formulating standards for adaptive educational hypermedia (AEH) systems that is currently under investigation by the EU ADAPT project. Within this project, design dimensions for high granularity patterns have been established. In this paper we focus on detailing lower granularity adaptive patterns based upon learning styles. Several patterns from existing AEH system case studies are identified and classified according to an extended learning style "onion" model. This model forms the basis of a learning style taxonomy, introduced here, whose components determine adaptation patterns for AEH. These patterns are of importance both for authoring, as well as for interfacing between adaptive hypermedia systems. From an authoring point of view, these patterns may be used to establish a fine-grain approach to instructional strategies that can be implemented in AEH systems, as a response to a particular learning style. The implementation of this adaptation pattern taxonomy is discussed, both generally and in detail.

Data integration enables combining data from various data sources in a standard format. Internet of things (IoT) applications use ontology approaches to provide a machine-understandable conceptualization of a domain. We propose a unified ontology schema approach to solve all IoT integration problems at once. The data unification layer maps data from different formats to data patterns based on the unified ontology model. This paper proposes a middleware consisting of an ontology-based approach that collects data from different devices. IoT middleware requires an additional semantic layer for cloud-based IoT platforms to build a schema for data generated from diverse sources. We tested the proposed model on real data consisting of approximately 160,000 readings from various sources in different formats like CSV, JSON, raw data, and XML. The data were collected through the file transfer protocol (FTP) and generated 960,000 resource description framework (RDF) triples. We evaluated the proposed approach by running different queries on different machines on SPARQL protocol and RDF query language (SPARQL) endpoints to check query processing time, validation of integration, and performance of the unified ontology model. The average response time for query execution on generated RDF triples on the three servers were approximately 0.144 seconds, 0.070 seconds, 0.062 seconds, respectively.

Abstract. In this paper we describe the principles of the design and development of an intelligent query interface, done in the context of the SEWASIE (SEmantic Webs and AgentS in Integrated Economies) European 1ST project. The SEWASIE project aims at enabling a uniform access to heterogeneous data sources through an integrated ontology. The query interface is meant to support a user in formulating a precise query-which best captures her/his information needs-even in the case of complete ignorance of the vocabulary of the ...

Clinical physicians and microbiologist are consistently challenged to find way to a cure Methicillin Resistant Staphylococcus aureus (MRSA). When selected drugs are tested on human; unique resistance were shown by this bacterial infection known as Methicillin Resistant Staphylococcus aureus (MRSA). If holistic approach is disregarded fewer options are left for medication to overcome this lethal toxicity. If solo range of drug treatment is applied only, the allied complications and consequences of infections may proliferate beyond critical levels. The research article is centred on primary microbial data collection (from urine and blood) in hospital. The emphasis of experimentation is to scrutinize the highest risk susceptible hospital area including sampled fluid. The precautionary and therapeutic measures are discussed along with alternative means of medication with judicious selection to achieve targeted and optimum outcome.

This article presents a paper-based Tangible User Interface (TUI) that facilitates the production of complex queries on a Cultural Heritage (CH) repository. The system helps to easily make use of the data elements and Boolean logic that describe the collections. This research presents a design methodology divided into two main phases: A User Experience (UX) and User Centred Design (UCD) where potential users’ behaviours are analysed, followed by the development and evaluation of the TUI prototype. The TUI uses off the shelf electronics and a paper-based set of tokens to engage the user with the system, thus facilitating the exploration with CH collections through querying.

The comprehension of linked data, consisting of classes, individuals, attributes, relationships, and other elements, is challenging yet important for effective use of linked data. An approach to improve software program comprehension is through the code city metaphor, in which object-oriented source code is visualized as a habitable city in 3D. We propose the linked-data city metaphor to support comprehension of linked data. Through improved linked data comprehension we in turn aim to support users in browsing linked data and in analyzing the structure of linked data. We discuss how different mappings and visualization of properties in the city metaphor may support users in browsing and structural analysis of linked data. A prototype implementation of linked data city in LD-R, a linked data-aware faceted browser, is presented.

In cases when the information being collected and processed originates by a multi-sensor system, one has to be aware of the impact of the approaches followed in designing the overall system behavior. Typically, there are many steps involved in processing sensory information, from the time a real-world event takes place until the information that describes it and captures its semantics is stored and is available for further exploitation. It this paper we analyze and discuss the options available in the design phase while we underline their respective strengths and weaknesses. The main contribution of the paper lies in the analysis of the factors that affect the behavior and performance of an information system responsible for fusing and integrating sensory information. The main components that constitute such systems are presented in depth, while every choice and the respective effects are discussed in an organized and complete manner.

The provision of the same pedagogical and educational methods to all students is pedagogically ineffective. In contrast, more effectively have proved the pedagogical strategies that adapt to the real individual skills of the students. An important innovation in this direction is the Adaptive Educational Systems (AES) that adjust the teaching content on educational needs and students' skills. Effective utilization of these approaches can be enhanced with Artificial Intelligence (AI) and Semantic Web technologies that can increase data generation, access, flow, integration, and comprehension using the very same open standards that drive the World Wide Web (URIs, HTTP, and HTML). This study proposes a novel Adaptive Educational eLearning System (AEeLS) that has the capacity to gather and analyze data from learning repositories and to adapt these to the educational curriculum according to the student skills and experience. It is an innovative hybrid machine learning system that combines a Semi-Supervised Classification method for ontology matching and a Recommendation Mechanism that uses a sophisticated method from neighborhood-based collaborative and content-based filtering techniques, in order to provide a personalized educational environment for each student.

In this article I describe software that facilitates “question-centric curricula” in which big questions, rather than academic disciplines, are the primary means of organizing educational resources. To find these questions, the software scans course catalogs and extracts all sentences ending in a question mark. To find connections between questions and courses, I present several computational techniques. One leverages the Library of Congress system; another implements so-called semantic technology that uses huge numbers of simple internet searches to ascertain the meaning of texts. The software assembles the results and shows, in one image, how every course at an institution relates to a given question.

Information retrieval technology has been central to the success of the Web. For semantic web documents or annotations to have an impact, they will have to be compatible with Web based indexing and retrieval technology. We discuss some of the underlying problems and issues central to extending information retrieval systems to handle annotations in semantic web languages. We also describe three prototype systems that we have implemented to explore these ideas.
