The popularity of ontologies for representing the semantics behind many real-world domains has created a growing pool of ontologies on various topics. While different ontologists, experts, and organizations create the vast majority of ontologies, often for internal use of for use in a narrow context, their domains frequently overlap in a wider context, specifically for complementary domains. To assist in the reuse of ontologies, this thesis proposes a bottom-up technique for creating concept anchors that are used for ontology matching. Anchors are ontology concepts that have been matched to concepts in an eternal ontology. The matching process is based on inductively derived decision trees rules for an ontology that are compared with rules derived for external ontologies. The matching algorithm is intended to match taxomonies, ontologies which define subsumption relations between concepts, with an associated database used to derive the decision trees. This thesis also introduces several algorithm evolution measures, and presents a set of use cases that demonstrate the strengths and weaknesses of the matching process.

Simplex Virus

Background Infection with the herpes simplex virus (HSV) is common but not well understood. Furthermore, there remains a social stigma surrounding HSV that can have psychosocial implications for those infected. Despite many patients infected with HSV experiencing mild-to-severe physical symptoms, only one subeffective treatment is available. A registry collecting real-world data reported by individuals potentially infected with HSV could help patients to better understand and manage their condition. Objective This study aimed to report on the development of a registry to collect real-world data reported by people who might be infected with HSV. Methods A case study design was selected as it provides a systematic and in-depth approach to investigating the planning phase of the registry. The case study followed seven stages: plan, design, prepare, collect, analyze, create, and share. We carried out semistructured interviews with experts, which were thematically analyzed and used to build use cases for the proposed registry. These use cases will be used to generate detailed models of how a real-world evidence registry might be perceived and used by different users. Results The following key themes were identified in the interviews: (1) stigma and anonymity, (2) selection bias, (3) understanding treatment and outcome gaps, (4) lifestyle factors, (5) individualized versus population-level data, and (6) severe complications of HSV. We developed use cases for different types of users of the registry, including individuals with HSV, members of the public, researchers, and clinicians. Conclusions This case study revealed key considerations and insights for the development of an appropriate registry to collect real-world data reported by people who might be infected with HSV. Further development and testing of the registry with different users is required. The registry must also be evaluated for the feasibility and effectiveness of collecting data to support symptom management. This registry has the potential to contribute to the development of vaccines and treatments and provide insights into the impact of HSV on other conditions.

The Web

Whilst access to the internet is becoming increasingly ubiquitous in highly populated, urban areas, for much of the planet web connectively is still largely absent. This is mainly due to geographic remoteness, but bad connectivity or governmental controls might also prevent web users from accessing desired resources. The authors have previously outlined a general approach to cope with such situations, which they termed “Web in your Pocket” (WiPo). WiPo assumes that the user has a smart device to which appropriate data, ideally in curated form, can be pre-loaded so that it remains accessible offline. In this chapter, the authors present the potential usability of WiPo by considering three important use-cases (tourism, health, and search and rescue) demonstrating the vast potential of WiPo. The chapter concludes by considering the practical issues that need to be overcome before it might be implemented in real-world situations.

This chapter describes example use cases for ubiquitous computing technology in a corporate environment that have been evaluated as prototypes under realistic conditions. The main example reduces risk in the handling of hazardous substances by detecting potentially dangerous storage situations and raising alarms if certain rules are violated. We specify the requirements, implementation decisions, and lessons learned from evaluation. It is shown that ubiquitous computing in a shop floor, warehouse, or retail environment can drastically improve real-world business processes, making them safer and more efficient.

This paper introduces the concept of Virtual Documents and its prototypical realization in our TNTBase system, a versioned XML database. Virtual Documents integrate XQuery-based computational facilities into documents like JSP/PHP do for relational queries. We view the integration of computation in documents as an enabling technology and evaluate it on a handful of real-world use cases.

By providing interoperability and shared meaning across actors and domains, lightweight domain ontologies are a cornerstone technology of the Semantic Web. This chapter investigates evidence sources for ontology learning and describes a generic and extensible approach to ontology learning that combines such evidence sources to extract domain concepts, identify relations between the ontology’s concepts, and detect relation labels automatically. An implementation illustrates the presented ontology learning and relation labeling framework and serves as the basis for discussing possible pitfalls in ontology learning. Afterwards, three use cases demonstrate the usefulness of the presented framework and its application to real-world problems.
