This knowledge is spread throughout individuals that most of time are not aware of each other vocabulary. In this case opportunities can be lost either because the potential around them is underestimated or correlating themes is burdensome. The work presented here is a tool intended to organize the informal vocabulary used by communities of practice in formal domain categories in order to establish a correlation between them and advice the user of the potential skills net he/she belongs to. Ontologies are used to relate domains and user's profile while agents capture user's preferences and provide useful information. The tool updates general information unburdening the user from tasks she/he is unfamiliar to. Experiments demonstrate the potential of this kind of tool envisaging its broader use and application in other domains.

In fact, cutting edge research requires expressive processing and network capacities for handling geographically disperse data from different disciplines, marking the birth of "escience", as in bioinformatics. In this context, this article introduces expert systems and the Semantic Web, whose construction depends on technologies for knowledge representation, such as ontologies. By spelling out a common set of concepts, these can make possible the integration of diverse and heterogeneous sets of data, facilitating the interoperability of information systems. This integration of data is a critical stage of the development of almost all computer systems, whether they are used in research activities, in new ways of organizing collaborative work, in e-science or in government or commercial activities. The article concludes by arguing that the construction of ontologies is a technological alternative for the interoperability of information systems, which may favor a new way of organizing collaborative work for the integrated management of electronic government purchases, particularly in the health sector.

The changes affect a full range of applications as well as the way users interact with computers. In the health domain, clinical research demands a lot of investment, effort and information in order to safely commercialize a new drug. The WebInVivo project aims at providing automated support for clinical research based on Web technologies. It includes mechanisms for sharing and reusing clinical trial information, such as protocols, protocol data, workflows and workflow metadata and for controlling the protocol life cycle, from modeling to execution. In this project, knowledge from the biomedical area permeates three segments of Brazilian society: (a) research and development, (b) health agents, and (c) the population. This knowledge will be made available through social networks for these segments of Brazilian society.

Knowledge about malicious program behavior forms the basis for constructing more secure information systems. In this article, we introduce MBO, a Malicious Behavior Ontology that represents complex behaviors of suspicious executions, and through inference rules calculates their associated threat level for analytical proposals. We evaluate MBO using over two thousand unique known malware and 385 unique known benign software. Results highlight the representativeness of the MBO for expressing typical malicious activities.

W2T 2020-21 includes six full papers and four short papers. They all address relevant issues in the field of information sharing for collaboration, including, big data analytics, knowledge engineering, linked open data, applications of smart Web technologies, and smart care. The papers address a portfolio of hot issues in research and applications of semantics, smart technologies (e.g., IoT, sensors, devices for tele-monitoring, and smart contents management) with crucial topics, such as big data analysis, knowledge representation, smart enterprise management, among the others. This track shows how cooperative technologies based on knowledge representation, intelligent tools, and enhanced Web engineering can enhance collaborative work through smart service design and delivery, so it contributes to radically change the role of the semantic Web and applications.

They all address relevant issues in the field of collaborative web, semantic technologies, ontologies, knowledge engineering, linked data and internet of things applied to themes of high impact on society, such as education, social inclusion and health. These papers propose to explore affordable technologies to promote and valorize rural areas, to develop ontologies for supporting simulation-based training in Medicine, to use semantic technologies in a framework for promoting reuse and interoperability of Electronic Health Records, as well as to use these technologies to provide recommendations in an Internet of Things device migration scenario.

It includes mechanisms for (a) sharing and reusing clinical trial assets, such as protocols, protocol data, workflows and workflow metadata and (b) controlling the protocol life cycle, from modelling to execution. In this project, collaboration in the biomedical area will permeate three segments of Brazilian society: (a) research and development, (b) health agents and (c) population at risk. The knowledge gained from this study will be complied and published through social networks directed to these segments of Brazilian society. Keywords-service-oriented computing; workflow management; social networks; web services; semantics; quality of service; e-health I.

Its purpose is to aid the process of community building, specially in the early phase of peer search and recognition in a distributed engineering environment, where multidisciplinary teams must be established. In this kind of problem information about possible candidates to make up the teams must be gathered from all available channels, including the electronic ones. Due to privacy issues, web based data mining systems are not efficient for the purpose of constructing candidate’s profiles, even if they can offer some help; therefore a distributed solution that permits each candidate’s workplace to be explored was developed. As a means of aggregating collected knowledge for sharing, a conceptual model, relating candidate’s profiles and their knowledge domain was developed in the form of an ontology. This strategy allows the system to be specialised in terms of t...

In this paper, we propose a healing architecture able to handle web service faults in a selfhealing way, discussing infrastructural faults and web service and Web application faults. The self-healing architecture manages repair actions, such as substitution of a faulty service or duplication of overloaded services. Implemented prototypes involving QoS in coordinated web services are illustrated and discussed. 1 1
