An Evolutionary Theory of Innovation and Strategic Platform Openness for Web 2.0 Businesses

We examine in this study technology adoption and diffusion of innovation from an evolutionary perspective that leads to an analysis that is different from extant literature and that adds to our theoretical understanding of platform innovation. Our evolutionary theory of innovation and platform openness refines and extends the currently prevailing simple innovation paradigms and allows the theoretical analysis of innovation as a truly dynamic multi-level phenomenon that affects organizational as well as industry change. We also present a formal Markovian process model that serves as a basis for simulating specific theoretical parameter settings and enables the examination of how organizational innovation strategies affect organizational performance as well as industry trends.The results of our simulation analysis suggest that platform openness plays a key role in innovation diffusion and fixation, especially in a Web 2.0 environment where the innovation is at a selective disadvantage or if the environment fosters an unrelenting radical innovation rate. The analysis also suggests that strategies that aim at decreasing competition in the Web 2.0 industry instead of opening the service platforms will not succeed in increasing innovation diffusion

Identifying and explicating knowledge on method transfer: a sectoral system of innovation approach

Post-print (lokagerð höfundar)With the advances in information technology and its increasing impact on humans and society, there has been an expanding need to spread knowledge from domain to domain. This need is not least in the area of human–computer interaction, which includes a rich culture of carrying out usability evaluations in many different domains and technology platforms. This paper aims to show how transfer of methods takes place, by explicating and formalizing the process. It will contribute to the quest for knowledge on the constituents of the process of transferring methodological knowledge and their relationships. A sectoral system of innovation approach is used to analyse the constituents of a selected sector, crisis management, where training is essential and which is rapidly adopting technology for operations and training. Two case studies are described where heuristics evaluation and user testing were applied on simulation software that allows training for crisis management. The analysis results in a process model, describing the transfer of methodological knowledge within the sectoral system of innovation framework.The research leading to these results has received funding from COST Action IC0904, Twintide, and the European Union Seventh Framework Programme (FP7/2007-2013) under Grant Agreement No. [FP7-242474], CRISIPeer Reviewe

WebAL Comes of Age: A review of the first 21 years of Artificial Life on the Web

We present a survey of the first 21 years of web-based artificial life (WebAL) research and applications, broadly construed to include the many different ways in which artificial life and web technologies might intersect. Our survey covers the period from 1994—when the first WebAL work appeared—up to the present day, together with a brief discussion of relevant precursors. We examine recent projects, from 2010–2015, in greater detail in order to highlight the current state of the art. We follow the survey with a discussion of common themes and methodologies that can be observed in recent work and identify a number of likely directions for future work in this exciting area

Three Essays on Growth and Innovation of Digital Platforms

Digital platforms are complex digital technology arrangements that enable the interaction of otherwise unaffiliated organisations. This interaction often generates novel outputs and as a result digital platforms are seen as a powerful driver of digital innovation. Yet exactly how digital platforms generate innovations by facilitating interaction merits further investigation. This dissertation illustrates aspects of how platforms grow and innovate using the case of the open-geo data platform OpenStreetMap. The study draws from both quantitative as well as qualitative analysis techniques applied to highly detailed data capturing the use, design, and operation of the platform over more than ten years. A series of computationally-intensive, mixedmethods studies were conducted to utilise the full scale of available empirical material while maintaining contextual richness relevant to the case. Embedded in recent topics on digital platforms, three empirical studies are presented. Each study focuses on one aspect of growth and innovation on digital platforms. The studies specifically examine; (i) how platform operators can stimulate generativity, that is the generation of novel outputs without direct input by the operator, (ii), how the unique attributes of digital technologies enable the creation of complex ecosystems that allow for highpaced changes in a platform’s architecture even if that increases the structural complexity of a platform, and, (iii) how participants coordinate contributions to a platform’s operation when they cannot rely on stable interfaces. Collectively these studies contribute to the understanding of how platforms generate new digital innovations

Composição de serviços para aplicações biomédicas

Doutoramento em Engenharia InformáticaA exigente inovação na área das aplicações biomédicas tem guiado a evolução das tecnologias de informação nas últimas décadas. Os desafios associados a uma gestão, integração, análise e interpretação eficientes dos dados provenientes das mais modernas tecnologias de hardware e software requerem um esforço concertado. Desde hardware para sequenciação de genes a registos electrónicos de paciente, passando por pesquisa de fármacos, a possibilidade de explorar com precisão os dados destes ambientes é vital para a compreensão da saúde humana. Esta tese engloba a discussão e o desenvolvimento de melhores estratégias informáticas para ultrapassar estes desafios, principalmente no contexto da composição de serviços, incluindo técnicas flexíveis de integração de dados, como warehousing ou federação, e técnicas avançadas de interoperabilidade, como serviços web ou LinkedData. A composição de serviços é apresentada como um ideal genérico, direcionado para a integração de dados e para a interoperabilidade de software. Relativamente a esta última, esta investigação debruçou-se sobre o campo da farmacovigilância, no contexto do projeto Europeu EU-ADR. As contribuições para este projeto, um novo standard de interoperabilidade e um motor de execução de workflows, sustentam a sucesso da EU-ADR Web Platform, uma plataforma para realizar estudos avançados de farmacovigilância. No contexto do projeto Europeu GEN2PHEN, esta investigação visou ultrapassar os desafios associados à integração de dados distribuídos e heterogéneos no campo do varíoma humano. Foi criada uma nova solução, WAVe - Web Analyses of the Variome, que fornece uma coleção rica de dados de variação genética através de uma interface Web inovadora e de uma API avançada. O desenvolvimento destas estratégias evidenciou duas oportunidades claras na área de software biomédico: melhorar o processo de implementação de software através do recurso a técnicas de desenvolvimento rápidas e aperfeiçoar a qualidade e disponibilidade dos dados através da adopção do paradigma de web semântica. A plataforma COEUS atravessa as fronteiras de integração e interoperabilidade, fornecendo metodologias para a aquisição e tradução flexíveis de dados, bem como uma camada de serviços interoperáveis para explorar semanticamente os dados agregados. Combinando as técnicas de desenvolvimento rápidas com a riqueza da perspectiva "Semantic Web in a box", a plataforma COEUS é uma aproximação pioneira, permitindo o desenvolvimento da próxima geração de aplicações biomédicas.The demand for innovation in the biomedical software domain has been an information technologies evolution driver over the last decades. The challenges associated with the effective management, integration, analyses and interpretation of the wealth of life sciences information stemming from modern hardware and software technologies require concerted efforts. From gene sequencing hardware to pharmacology research up to patient electronic health records, the ability to accurately explore data from these environments is vital to further improve our understanding of human health. This thesis encloses the discussion on building better informatics strategies to address these challenges, primarily in the context of service composition, including warehousing and federation strategies for resource integration, as well as web services or LinkedData for software interoperability. Service composition is introduced as a general principle, geared towards data integration and software interoperability. Concerning the latter, this research covers the service composition requirements within the pharmacovigilance field, namely on the European EU-ADR project. The contributions to this area, the definition of a new interoperability standard and the creation of a new workflow-wrapping engine, are behind the successful construction of the EUADR Web Platform, a workspace for delivering advanced pharmacovigilance studies. In the context of the European GEN2PHEN project, this research tackles the challenges associated with the integration of heterogeneous and distributed data in the human variome field. For this matter, a new lightweight solution was created: WAVe, Web Analysis of the Variome, provides a rich collection of genetic variation data through an innovative portal and an advanced API. The development of the strategies underlying these products highlighted clear opportunities in the biomedical software field: enhancing the software implementation process with rapid application development approaches and improving the quality and availability of data with the adoption of the Semantic Web paradigm. COEUS crosses the boundaries of integration and interoperability as it provides a framework for the flexible acquisition and translation of data into a semantic knowledge base, as well as a comprehensive set of interoperability services, from REST to LinkedData, to fully exploit gathered data semantically. By combining the lightness of rapid application development strategies with the richness of its "Semantic Web in a box" approach, COEUS is a pioneering framework to enhance the development of the next generation of biomedical applications
