    jung2007bInternational audienceQuery transformation is a serious hurdle on semantic peer-to-peer environment. The problem is that the transformed queries might lose some information from the original one, as continuously traveling p2p networks. We mainly consider two factors; i) number of transformations and// ii) quality of ontology alignment. In this paper, we propose semantic centrality (SC) measurement meaning the power of semantic bridging on semantic p2p environment. Thereby, we want to build semantically cohesive user subgroups, and find out the best peers for query transformation, i.e., minimizing information loss. We have shown an example for retrieving image resources annotated on p2p environment by using query transformation based on SC

    The applicability of computational and dynamical systems models to organisms is scrutinized, using examples from developmental biology and cognition. Developmental morphogenesis is dependent on the inherent material properties of developing tissues, a non-computational modality, but cell differentiation, which utilizes chromatin-based revisable memory banks and program-like function-calling, via the developmental gene co-expression system unique to metazoans, has a quasi-computational basis. Multi-attractor dynamical models are argued to be misapplied to global properties of development, and it is suggested that along with computationalism, dynamicism is similarly unsuitable to accounting for cognitive phenomena. Proposals are made for treating brains and other nervous tissues as novel forms of excitable matter with inherent properties which enable the intensification of cell-based basal cognition capabilities present throughout the tree of life

    An Application of Adaptive Network Urbanism A Study Case from Border Area in Indonesia

    Today’s architect and urban designer neglected the networked world\u27s vast flows developed by other innovators. An urban space may consist of several network system series. Urban network capacity to evolve within multiple choices concerning connections or adaptive shall be considered ultimately in the planning direction. As an adaptive principle, the network should be able to modify its own structure, and it should be adapted to various changes and changing needs and desire of its users. Adaptive network urbanism considers as a planning approach, which focuses on the dynamic system that can be evolving dynamically. The application of adaptive planning can be developed through anticipation and adaptation by preparing “plans” that may respond to the needs. This study applies the adaptive approach at the border area by proposing new networks on the existing infrastructure network to watch the “dynamical interplay” among areas, especially among Paloh district as a border area and Sambas district as the capital city. This study is specifically tried to identify the new links or expansion configuration by repeatedly proposing new links and re-calculations until it finds or gives alternatives for the best connection or “a prepared plan”. There are five types of “adaptive" approaches to be considered in developing the strategic areas from the research findings. These approaches are (1) network transforms or new link, (2)network extension, (3) addition (new) node, (4) other supporting networksas a supplement network, and (5) inter-country connection to improverelationship and cooperation

    Social and Symbolic Boundaries in the Upper Egyptian Town of Pathyris (2nd to Early 1st Cent. BCE)

    This paper asks and tests questions about ancient group boundaries against empirical data through a case study of the small-scale community of Pathyris in southern Egypt (186-88 BCE). By means of studying 382 documentary texts associated with 16 family archives from a distinct network perspective, the author jumps between scales, perspectives and methods to demonstrate the relevance of Social Network Analysis for boundary-work on ancient communities, yet with a critical eye. In doing so, she analyses a socio-economic network representing the community as well as male and female subnetworks in it, before exploring the intersection between these groups. A general lack of clear divisions observed between studied attributes like sex and legal ethnic status leads her to conclude that neither seem to have represented strict social boundaries that dictated with whom the inhabitants interacted. Este artigo questiona e testa a delimitação de grupos na Antiguidade a partir de dados empĂ­ricos da pequena comunidade de Pathyris, ao sul do Egito (186-88 a.C.). Por meio do estudo de 382 textos associados a 16 arquivos familiares e a partir de uma perspectiva distinta da noção de rede, a autora salta entre escalas, perspectivas e mĂ©todos para demonstrar a relevĂąncia da AnĂĄlise de Redes para o estudo de fronteiras em comunidades antigas, mas com um olhar crĂ­tico. Ao fazer isso, ela analisa uma rede socioeconĂŽmica que representa a comunidade, bem como as suas sub-redes masculinas e femininas antes de explorar a interseção entre esses grupos. A ausĂȘncia de divisĂ”es claras observadas entre atributos estudados como sexo, etnia e status legal a leva a concluir que nenhum destes aspectos parece ter representado limites sociais estritos que ditavam as interaçÔes dos habitantes.Peer reviewe

    dissertationA broad range of applications capture dynamic data at an unprecedented scale. Independent of the application area, finding intuitive ways to understand the dynamic aspects of these increasingly large data sets remains an interesting and, to some extent, unsolved research problem. Generically, dynamic data sets can be described by some, often hierarchical, notion of feature of interest that exists at each moment in time, and those features evolve across time. Consequently, exploring the evolution of these features is considered to be one natural way of studying these data sets. Usually, this process entails the ability to: 1) define and extract features from each time step in the data set; 2) find their correspondences over time; and 3) analyze their evolution across time. However, due to the large data sizes, visualizing the evolution of features in a comprehensible manner and performing interactive changes are challenging. Furthermore, feature evolution details are often unmanageably large and complex, making it difficult to identify the temporal trends in the underlying data. Additionally, many existing approaches develop these components in a specialized and standalone manner, thus failing to address the general task of understanding feature evolution across time. This dissertation demonstrates that interactive exploration of feature evolution can be achieved in a non-domain-specific manner so that it can be applied across a wide variety of application domains. In particular, a novel generic visualization and analysis environment that couples a multiresolution unified spatiotemporal representation of features with progressive layout and visualization strategies for studying the feature evolution across time is introduced. This flexible framework enables on-the-fly changes to feature definitions, their correspondences, and other arbitrary attributes while providing an interactive view of the resulting feature evolution details. Furthermore, to reduce the visual complexity within the feature evolution details, several subselection-based and localized, per-feature parameter value-based strategies are also enabled. The utility and generality of this framework is demonstrated by using several large-scale dynamic data sets

    Interactive sonification exploring emergent behavior applying models for biological information and listening

    Sonification is an open-ended design task to construct sound informing a listener of data. Understanding application context is critical for shaping design requirements for data translation into sound. Sonification requires methodology to maintain reproducibility when data sources exhibit non-linear properties of self-organization and emergent behavior. This research formalizes interactive sonification in an extensible model to support reproducibility when data exhibits emergent behavior. In the absence of sonification theory, extensibility demonstrates relevant methods across case studies. The interactive sonification framework foregrounds three factors: reproducible system implementation for generating sonification; interactive mechanisms enhancing a listener's multisensory observations; and reproducible data from models that characterize emergent behavior. Supramodal attention research suggests interactive exploration with auditory feedback can generate context for recognizing irregular patterns and transient dynamics. The sonification framework provides circular causality as a signal pathway for modeling a listener interacting with emergent behavior. The extensible sonification model adopts a data acquisition pathway to formalize functional symmetry across three subsystems: Experimental Data Source, Sound Generation, and Guided Exploration. To differentiate time criticality and dimensionality of emerging dynamics, are applied between subsystems to maintain scale and symmetry of concurrent processes and temporal dynamics. Tuning functions accommodate sonification design strategies that yield order parameter values to render emerging patterns discoverable as well as , to reproduce desired instances for clinical listeners. Case studies are implemented with two computational models, Chua's circuit and Swarm Chemistry social agent simulation, generating data in real-time that exhibits emergent behavior. is introduced as an informal model of a listener's clinical attention to data sonification through multisensory interaction in a context of structured inquiry. Three methods are introduced to assess the proposed sonification framework: Listening Scenario classification, data flow Attunement, and Sonification Design Patterns to classify sound control. Case study implementations are assessed against these methods comparing levels of abstraction between experimental data and sound generation. Outcomes demonstrate the framework performance as a reference model for representing experimental implementations, also for identifying common sonification structures having different experimental implementations, identifying common functions implemented in different subsystems, and comparing impact of affordances across multiple implementations of listening scenarios

    This open access book summarises the latest developments on data management in the EU H2020 ENVRIplus project, which brought together more than 20 environmental and Earth science research infrastructures into a single community. It provides readers with a systematic overview of the common challenges faced by research infrastructures and how a ‘reference model guided’ engineering approach can be used to achieve greater interoperability among such infrastructures in the environmental and earth sciences. The 20 contributions in this book are structured in 5 parts on the design, development, deployment, operation and use of research infrastructures. Part one provides an overview of the state of the art of research infrastructure and relevant e-Infrastructure technologies, part two discusses the reference model guided engineering approach, the third part presents the software and tools developed for common data management challenges, the fourth part demonstrates the software via several use cases, and the last part discusses the sustainability and future directions

    The Alor-Pantar languages: History and typology (Second edition)

    Get PDF
    The Alor-Pantar family constitutes the westernmost outlier group of Papuan (Non-Austronesian) languages. Its twenty or so languages are spoken on the islands of Alor and Pantar, located just north of Timor, in eastern Indonesia. Together with the Papuan languages of Timor, they make up the Timor-Alor-Pantar family. The languages average 5,000 speakers and are under pressure from the local Malay variety as well as the national language, Indonesian. This volume studies the internal and external linguistic history of this interesting group, and showcases some of its unique typological features, such as the preference to index the transitive patient-like argument on the verb but not the agent-like one; the extreme variety in morphological alignment patterns; the use of plural number words; the existence of quinary numeral systems; the elaborate spatial deictic systems involving an elevation component; and the great variation exhibited in their kinship systems. Unlike many other Papuan languages, Alor-Pantar languages do not exhibit clause-chaining, do not have switch reference systems, never suffix subject indexes to verbs, do not mark gender, but do encode clusivity in their pronominal systems. Indeed, apart from a broadly similar head-final syntactic profile, there is little else that the Alor-Pantar languages share with Papuan languages spoken in other regions. While all of them show some traces of contact with Austronesian languages, in general, borrowing from Austronesian has not been intense, and contact with Malay and Indonesian is a relatively recent phenomenon in most of the Alor-Pantar region. This is the second edition of the volume that was originally published in 2014. In this edition, typographical errors have been corrected, small textual improvements have been implemented, broken URL links repaired or removed, and references updated. The overall content of the chapters has not been changed

    Annotation, exploitation and evaluation of parallel corpora

    Get PDF
    Exchange between the translation studies and the computational linguistics communities has traditionally not been very intense. Among other things, this is reflected by the different views on parallel corpora. While computational linguistics does not always strictly pay attention to the translation direction (e.g. when translation rules are extracted from (sub)corpora which actually only consist of translations), translation studies are amongst other things concerned with exactly comparing source and target texts (e.g. to draw conclusions on interference and standardization effects). However, there has recently been more exchange between the two fields – especially when it comes to the annotation of parallel corpora. This special issue brings together the different research perspectives. Its contributions show – from both perspectives – how the communities have come to interact in recent years
