Theories of Informetrics and Scholarly Communication

Scientometrics have become an essential element in the practice and evaluation of science and research, including both the evaluation of individuals and national assessment exercises. Yet, researchers and practitioners in this field have lacked clear theories to guide their work. As early as 1981, then doctoral student Blaise Cronin published "The need for a theory of citing" —a call to arms for the fledgling scientometric community to produce foundational theories upon which the work of the field could be based. More than three decades later, the time has come to reach out the field again and ask how they have responded to this call. This book compiles the foundational theories that guide informetrics and scholarly communication research. It is a much needed compilation by leading scholars in the field that gathers together the theories that guide our understanding of authorship, citing, and impact

The Translocal Event and the Polyrhythmic Diagram

This thesis identifies and analyses the key creative protocols in translocal performance practice, and ends with suggestions for new forms of transversal live and mediated performance practice, informed by theory. It argues that ontologies of emergence in dynamic systems nourish contemporary practice in the digital arts. Feedback in self-organised, recursive systems and organisms elicit change, and change transforms. The arguments trace concepts from chaos and complexity theory to virtual multiplicity, relationality, intuition and individuation (in the work of Bergson, Deleuze, Guattari, Simondon, Massumi, and other process theorists). It then examines the intersection of methodologies in philosophy, science and art and the radical contingencies implicit in the technicity of real-time, collaborative composition. Simultaneous forces or tendencies such as perception/memory, content/ expression and instinct/intellect produce composites (experience, meaning, and intuition- respectively) that affect the sensation of interplay. The translocal event is itself a diagram - an interstice between the forces of the local and the global, between the tendencies of the individual and the collective. The translocal is a point of reference for exploring the distribution of affect, parameters of control and emergent aesthetics. Translocal interplay, enabled by digital technologies and network protocols, is ontogenetic and autopoietic; diagrammatic and synaesthetic; intuitive and transductive. KeyWorx is a software application developed for realtime, distributed, multimodal media processing. As a technological tool created by artists, KeyWorx supports this intuitive type of creative experience: a real-time, translocal “jamming” that transduces the lived experience of a “biogram,” a synaesthetic hinge-dimension. The emerging aesthetics are processual – intuitive, diagrammatic and transversal

Video Games for Earthly Survival: Gaming in the Post-Anthropocene

In this paper I evaluate the sixth mass extinction on planet Earth, and its implications for the medium of the video game. The Anthropocene, a term popularized by the end of the 20th century to refer to the geological impact of human beings on planet Earth, assumes temporal development, a ‘before’ and ‘after’ the appearance of humankind. The ‘after’ period, the Post-Anthropocene, is repeatedly claimed by scientists to be approaching within the next few decades, as over-consumption is destroying vital resources of the planet. Allegedly, the sixth mass extinction in the history of our planet is already unfolding, and might determine the disappearance of life from Earth and, as far as we know, from the Universe and beyond. Video games responding to the arrival of the future is not just imagined in fictional settings (e.g. The Legenda of Zelda: Majora’s Mask, Nintendo, 2000; Horizon: Zero Dawn, Guerrilla Games, 2017), but within game design. In the last decade an increasing number of video games requiring limited human intervention has been released. Incremental/ idle games such as Cookie Clicker (Julien Thiennot, 2013) and AdVenture Capitalist (Hyper Hippo Productions, 2014) require an initial input from the player to start, and then keep playing themselves in the background operations of a laptop or smartphone. Virtual environments can be entirely designed by algorithms, as experimented by Hello Games for No Man’s Sky (2016). Artificial Intelligence is also used to play games. Screeps, a massive-multiplayer online game, requires players to program an AI that will play the game in their place, and which will “live within the game even while you are offline” (Screeps Team, 2014). Ghost cars in racing games replace the human actor with a representation of their performance. The same concept is further explored by the Drivatar of the Forza Motorsport series (Microsoft Studios, 2005-2017), which simulates the driving style of the player and competes online against other AI-controlled cars. These are only some of the examples that suggest that human beings are becoming peripheral in the act of playing games. In short, it is probably becoming ‘easier to imagine the end of the world than the end of gaming’. While studies on games with no players, and on the non-human side of gaming, have been proposed in the past, my presentation takes a non-normative and non-systemic approach to the study of games for the Post-Anthropocene. I am concerned with the creative potential of the paradoxes, spoofs, and contradictions opened by games that take Man/Anthropos as being no longer at the centre of ‘interaction’, ‘fun’, and many other mythological aspects of digital gaming. Nonhuman gaming questions the historical, political, ecological and even geological situatedness of our knowledge on games and gamers, interaction and passivity, life and death

The Paranoiac-Critical Method of Reflectance Transformation Imaging

A performative talk examining Reflectance Transformation Imaging (RTI), an open source computational photographic process that is transforming methodologies in archaeology and heritage conservation for its ability to interactively re-light artefacts within a virtual hemisphere of illumination and extrude a digital topography that is hyper-legible in space-time, from its contemporary application in facial recognition via Bertrand Tavernier's 1980 science fiction film La Mort en Direct and a return of the death mask through digital extrusion, ultimately locating a progenitor of the heightened objectivity promised by RTI paradoxically in Surrealist photography and the fugitive facialities of Salvador Dali's Paranoiac-Critical Method. As emerging imaging technologies such as RTI are seen to open novel ways of extracting latent data from historical artefacts, reassembling objects of study in a new (virtual) light, collateral opportunities provided by these technologies to re-enter archival still and moving image recordings inadvertently recalibrate their spatio-temporal ground and destabilise their indexical reading through an excessive production of new traces and signs. If methodologies can be seen to play a significant role in constructing their objects of study, then emerging computational imaging operations such as RTI have their own subjectivities to disclose: In performing a media archaeology of this digital process, the talk proposes that we not only narrate the subjects of our study but the very tools of investigation themselves

In the current information age, massive amounts of data are gathered, at a rate prohibiting their effective structuring, analysis, and conversion into useful knowledge. This information overload is manifested both in large numbers of data objects recorded in data sets, and large numbers of attributes, also known as high dimensionality. This dis-sertation deals with problems originating from high dimensionality of data representation, referred to as the “curse of dimensionality,” in the context of machine learning, data mining, and information retrieval. The described research follows two angles: studying the behavior of (dis)similarity metrics with increasing dimensionality, and exploring feature-selection methods, primarily with regard to document representation schemes for text classification. The main results of the dissertation, relevant to the first research angle, include theoretical insights into the concentration behavior of cosine similarity, and a detailed analysis of the phenomenon of hubness, which refers to the tendency of some points in a data set to become hubs by being in-cluded in unexpectedly many k-nearest neighbor lists of other points. The mechanisms behind the phenomenon are studied in detail, both from a theoretical and empirical perspective, linking hubness with the (intrinsic) dimensionality of data, describing its interaction with the cluster structure of data and the information provided by class la-bels, and demonstrating the interplay of the phenomenon and well known algorithms for classification, semi-supervised learning, clustering, and outlier detection, with special consideration being given to time-series classification and information retrieval. Results pertaining to the second research angle include quantification of the interaction between various transformations of high-dimensional document representations, and feature selection, in the context of text classification.U tekućem „informatičkom dobu“, masivne količine podataka se sakupljaju brzinom koja ne dozvoljava njihovo efektivno strukturiranje, analizu, i pretvaranje u korisno znanje. Ovo zasićenje informacijama se manifestuje kako kroz veliki broj objekata uključenih u skupove podataka, tako i kroz veliki broj atributa, takođe poznat kao velika dimenzionalnost. Disertacija se bavi problemima koji proizilaze iz velike dimenzionalnosti reprezentacije podataka, često nazivanim „prokletstvom dimenzionalnosti“, u kontekstu mašinskog učenja, data mining-a i information retrieval-a. Opisana istraživanja prate dva pravca: izučavanje ponašanja metrika (ne)sličnosti u odnosu na rastuću dimenzionalnost, i proučavanje metoda odabira atributa, prvenstveno u interakciji sa tehnikama reprezentacije dokumenata za klasifikaciju teksta. Centralni rezultati disertacije, relevantni za prvi pravac istraživanja, uključuju teorijske uvide u fenomen koncentracije kosinusne mere sličnosti, i detaljnu analizu fenomena habovitosti koji se odnosi na tendenciju nekih tačaka u skupu podataka da postanu habovi tako što bivaju uvrštene u neočekivano mnogo lista k najbližih suseda ostalih tačaka. Mehanizmi koji pokreću fenomen detaljno su proučeni, kako iz teorijske tako i iz empirijske perspektive. Habovitost je povezana sa (latentnom) dimenzionalnošću podataka, opisana je njena interakcija sa strukturom klastera u podacima i informacijama koje pružaju oznake klasa, i demonstriran je njen efekat na poznate algoritme za klasifikaciju, semi-supervizirano učenje, klastering i detekciju outlier-a, sa posebnim osvrtom na klasifikaciju vremenskih serija i information retrieval. Rezultati koji se odnose na drugi pravac istraživanja uključuju kvantifikaciju interakcije između različitih transformacija višedimenzionalnih reprezentacija dokumenata i odabira atributa, u kontekstu klasifikacije teksta
