Embedded devices based on emerging technologies of the Internet of Things (IoT) are used to provide resources, business models and opportunities to build potential industrial systems improving manufacturing systems with efficient operations. In this context, IoT networks are dynamic environments and changes are also being increasingly frequent, modifying the environment execution. Nevertheless, severe...
The management of provenance information plays a key role in the scientific experimentation domain, since scientists often need to examine and audit the results obtained from experiments. In addition, provenance data are essential to ensure reproducibility and reuse of experiments or artifacts produced by them. In this way, the objective of this work is to present an ontology to support the researchers...
With the giddy growth of the amount of the information data through constant interaction and sharing in daily life, the mobile Internet has shifted from the lack of information to information overload. How to satisfy readers' individual needs from the disorder and mixture data has become an urgent problem to be solved. This paper combines the context information into the recommended process, and constructs...
One of the aspects brought by the use of connected mobile devices in education is the possibility of learning in different environments, using physical environmental factors in its advantage. These factors are part of what we define as “mobile context”, which is comprised by different information dimensions: temporal, physical, and social. This information can be modelled as an ontology and used in...
As elderly care is getting more and more important, monitoring of activity of daily living (ADL) has become an active research topic. Both robotic and pervasive computing domains, through smart homes, are creating opportunities to move forward in ADL field. Multiple techniques were proposed to identify activities, each with their features, advantages and limits. However, it is a very challenging issue...
A search system that allows the users to search and find the most interesting software artifacts based on the current context of the user is highly desirable. This paper sets forth the requirements of contextual search for software engineering. A context for software engineering is defined by four dimensions in. A contextual search system is presented to address the requirements. We conclude that...
With various connectivity and communication protocols, it is conceivable that all raw data from sensor devices can be made available in the Internet. However, this imposes a significant intricacy when dealing with the amount of information and the management of the devices. To alleviate the problem, this paper presents a design and implementation of a prototype IoT gateway framework that exposes high-level...
A context model plays a significant role in developing context-aware architectures and consequently on realizing context-awareness, which is important in today's dynamic computing environments. These architectures monitor and analyse their environments to enable context-aware applications to effortlessly and appropriately respond to users' computing needs. These applications make the use of computing...
This paper makes a contribution to the development of computational archival science by thinking about and linking computational and archival thinking. It suggests that archival thinking and the archival problem space encompasses questions about the nature of consciousness, highlighting how these questions seem to be apparent within the fundamental archival principles of respect des fonds, provenance...
Complex adaptive systems are in the heart of smart city operations. Developing such systems is very challenging. Current user-driven techniques for modeling the system domain are not sufficient for supporting the development of such systems. Additionally, in the majority of cases, existing work focused on user interface adaptation without considering content personalization. In this paper, we propose...
Medical tourism is a domain rich of data that are stored in many hundreds of data sources. Many of these sources should be used during the development of tourism information systems. That is why, it is very important to create a referential model that represents the medical tourism in Tunisia. The e-tourism ontology provides a way to achieve integration and interoperability through the use of shared...
The scale of the social web has integrated users in order to organize shared resources. Users freely associate keywords (tags) to resources. This collection of tags creates a folksonomy. Folksonomy is a collaborative tagging system, which has grown popular with its simplicity of free tagging. However, it rises up a number of issues such as ambiguous and redundant tags. So as to achieve an optimal...
The Cyc project was begun in the mid-80 s by Doug Lenat to become an ontology of “all commonsense knowledge.” This goal was often defined as all the knowledge that one would need in order to understand encyclopedia articles. For this reason the name “Cyc” was derived from “encyclopedia” and is pronounced that way. A corollary is that the Cyc Language (CycL) must be designed to be expressive enough...
In a related work, the author developed an approach to support model-based system engineering (MBSE) which ensures the conformance to a standard metamodel such as UML, SysML, or NAF, with dedicated project ontologies in order to ease the understanding and creation of models. The proposed mix approach brings flexibility and opens perspectives to support MBSE via predefined templates. However, the usage...
In this paper we propose a new approach to complex comfort management based on ontologies, being the main result of undergoing GOLIATH project. The approach comprises an application of Internet-of-Things (IoT) devices, an abstraction layer (SITE), a smart IoT middleware and a Multi-Agent System (MAS). Those elements allow a user to ask the system in a simple and natural way to control one or more...
Data provenance has been an active area of research as a means to standardize how the origin of data, process event history, and what or who was responsible for influencing results is explained. The common trend in capturing provenance is to collect all possible information, and then attempt to extract relevant information from the entire collection, which is not efficient especially at runtime. Unless...
In nascent areas, such as Smart Manufacturing, new collaborative research and development programs (R&D) are frequently formed with the goal to ignite the innovation lifecycle. Yet, clearly formulating common goals and enabling shared understanding of key concepts, which are critical to achieving these goals, often involve long, drawn-out processes. These processes typically involve road-mapping...
The main problem of rule-based information extraction technique is that the extraction rules tend to be specifically designed for specific information or document structure; hence it cannot be directly used in another without some proper modifications. Semi-structured documents like tables present another challenge to information extraction; since there are no standards on how to design it, the structure...
The fundamental objective of an information search system based on interest center and the user profile is to return, from a collection of documents, the elements that are relevant to specific user needs. The selection of only documents interesting a user is done on the basis of interest center, calculated from the information about the user named user profile. The information retrieval systems converge...
The emergence of pervasive computing and user mobility leads to the need for dynamic adaptation of user interaction on the documents which generally are multimedia oriented. The exchange of multimedia documents has a special place. In this paper we propose an approach for modeling context in pervasive computing environments for multimedia documents adaptation. Many researchers work in the area of...
