Due to the increasing number of information sources available on the web and their distribution and heterogeneity, ontology alignment became a very important and inevitable problem to resolve in order to ensure semantic interoperability between these sources. Instance-based ontology alignment represents a very promising technique to find semantic correspondences between entities of different ontologies. In practice, two situations may arise: ontologies that share common instances and those share few or do not share common instances. In this paper, the authors describe a new approach to manage the latter case. This approach exploits the reasoning on ontologies in order to create a corpus of common instances. They have used the Biblio and Finance tests of Benchmark series of the OAEI 2012 evaluation campaign to evaluate the performance of their approach. The results obtained show the good performance of the authors' approach compared to ontology alignment systems and improves significantly the instance-based and reasoning-based methods.

Different repositories of ontology are available on the web to share common understandings of the knowledge of different domains with semantic web applications. They store, index, organize, and share ontologies and alignments between them that allow applications to search for and use the appropriate semantics on the fly. The quality of the ontologies and the alignments between them is a great challenge to guarantee the usefulness of ontology repositories. Like ontologies, alignments are subject to changes throughout their life cycle, which can decrease their quality. As a result, alignments must be evolved and maintained in order to keep up with the change in ontology or to meet the demands of applications and users. This chapter reviews and classifies the main ontology alignment change approaches. In addition, the chapter presents a new approach for the alignment change problem. The approach proposes a general framework that consists of a process of change. Various methods, each with a specific purpose, are proposed to automate and support the change process.

In recent years — and especially since the 2016 presidential election — numerous media organizations, newspapers, and policy advocates have made efforts to help Americans become more careful consumers of the information they see online. In K-12 and higher education, the main approach has been to provide students with checklists they can use to assess the credibility of individual websites. However, the checklist approach is outdated. It would be far better to teach young people to follow the lead of professional fact-checkers: When confronted by a new and unfamiliar website, they begin by looking elsewhere on the web, searching for any information that might shed light on who created the site in question and for what purpose.

Next is a presentation of the complete system architecture, followed by a discussion of the details of the various services. Amongst these services, management and simulation of tactical planning, management of data and streaming video, the system also presents a service for the annotation of the interested spatial objects. Annotation deploys the web services (Alonso, Casati, Kuno, & Machiraju, 2004) exported by OpenStreetMap (OpenStreetMap) with the purpose to exploit the on-line information sources continuously updated by the social networks communities.

Through the concept of Cognitive Authority, information relevance and quality have been related to the expertise/skill of those who publish and share information on the Web. This chapter discusses how the concept of cognitive authority can be used in order to improve the information retrieval on folksonomy-based systems. The hypothesis is that a ranking scheme that takes into account the cognitive authority of the information sources provides results of higher relevance and quality to users. To verify this hypothesis, the Folkauthority approach is adopted; a ranking scheme called AuthorityRank is proposed; and an information retrieval system, named AuthoritySearch, is built. A real social network is used to simulate the authority relationship among users, and the AuthorityRank scheme is compared with the tf-idf scheme using the NDCG metric. The results indicate a statistically significant improvement in the quality and relevance of the information obtained through the use of the AuthorityRank scheme.

The ontology alignment process aims at generating a set of correspondences between entities of two ontologies. It is an important task, notably in the semantic web research, because it allows the joint consideration of resources defined in different ontologies. In this article, the authors developed an ontology alignment system called ABCMap+. It uses an optimization method based on artificial bee colonies (ABC) to solve the problem of optimizing the aggregation of three similarity measures of different matchers (syntactic, linguistic and structural) to obtain a single similarity measure. To evaluate the ABCMap+ ontology alignment system, authors considered the OAEI 2012 alignment system evaluation campaign. Experiments have been carried out to get the best ABCMap+'s alignment. Then, a comparative study showed that the ABCMap+ system is better than participants in the OAEI 2012 in terms of Recall and Precision.
