Modelling Scholarly Debate: Conceptual Foundations for Knowledge Domain Analysis Technology

Knowledge Domain Analysis (KDA) research investigates computational support for users who desire to understand and/or participate in the scholarly inquiry of a given academic knowledge domain. KDA technology supports this task by allowing users to identify important features of the knowledge domain such as the predominant research topics, the experts in the domain, and the most influential researchers. This thesis develops the conceptual foundations to integrate two identifiable strands of KDA research: Library and Information Science (LIS), which commits to a citation-based Bibliometrics paradigm, and Knowledge Engineering (KE), which adopts an ontology-based Conceptual Modelling paradigm. A key limitation of work to date is its inability to provide machine-readable models of the debate in academic knowledge domains. This thesis argues that KDA tools should support users in understanding the features of scholarly debate as a prerequisite for engaging with their chosen domain. To this end, the thesis proposes a Scholarly Debate Ontology which specifies the formal vocabulary for constructing representations of debate in academic knowledge domains. The thesis also proposes an analytical approach that is used to automatically detect clusters of viewpoints as particularly important features of scholarly debate. This approach combines aspects of both the Conceptual Modelling and Bibliometrics paradigms. That is, the method combines an ontological focus on semantics and a graph-theoretical focus on structure in order to identify and reveal new insights about viewpoint-clusters in a given knowledge domain. This combined ontological and graph-theoretical approach is demonstrated and evaluated by modelling and analysing debates in two domains. The thesis reflects on the strengths and limitations of this approach, and considers the directions which this work opens up for future research into KDA technology

Coalition based approach for shop floor agility – a multiagent approach

Dissertation submitted for a PhD degree in Electrical Engineering, speciality of Robotics and Integrated Manufacturing from the Universidade Nova de Lisboa, Faculdade de Ciências e TecnologiaThis thesis addresses the problem of shop floor agility. In order to cope with the disturbances and uncertainties that characterise the current business scenarios faced by manufacturing companies, the capability of their shop floors needs to be improved quickly, such that these shop floors may be adapted, changed or become easily modifiable (shop floor reengineering). One of the critical elements in any shop floor reengineering process is the way the control/supervision architecture is changed or modified to accommodate for the new processes and equipment. This thesis, therefore, proposes an architecture to support the fast adaptation or changes in the control/supervision architecture. This architecture postulates that manufacturing systems are no more than compositions of modularised manufacturing components whose interactions when aggregated are governed by contractual mechanisms that favour configuration over reprogramming. A multiagent based reference architecture called Coalition Based Approach for Shop floor Agility – CoBASA, was created to support fast adaptation and changes of shop floor control architectures with minimal effort. The coalitions are composed of agentified manufacturing components (modules), whose relationships within the coalitions are governed by contracts that are configured whenever a coalition is established. Creating and changing a coalition do not involve programming effort because it only requires changes to the contract that regulates it

Embedding Predications

Written communication is rarely a sequence of simple assertions. More often, in addition to simple assertions, authors express subjectivity, such as beliefs, speculations, opinions, intentions, and desires. Furthermore, they link statements of various kinds to form a coherent discourse that reflects their pragmatic intent. In computational semantics, extraction of simple assertions (propositional meaning) has attracted the greatest attention, while research that focuses on extra-propositional aspects of meaning has remained sparse overall and has been largely limited to narrowly defined categories, such as hedging or sentiment analysis, treated in isolation. In this thesis, we contribute to the understanding of extra-propositional meaning in natural language understanding, by providing a comprehensive account of the semantic phenomena that occur beyond simple assertions and examining how a coherent discourse is formed from lower level semantic elements. Our approach is linguistically based, and we propose a general, unified treatment of the semantic phenomena involved, within a computationally viable framework. We identify semantic embedding as the core notion involved in expressing extra-propositional meaning. The embedding framework is based on the structural distinction between embedding and atomic predications, the former corresponding to extra-propositional aspects of meaning. It incorporates the notions of predication source, modality scale, and scope. We develop an embedding categorization scheme and a dictionary based on it, which provide the necessary means to interpret extra-propositional meaning with a compositional semantic interpretation methodology. Our syntax-driven methodology exploits syntactic dependencies to construct a semantic embedding graph of a document. Traversing the graph in a bottom-up manner guided by compositional operations, we construct predications corresponding to extra-propositional semantic content, which form the basis for addressing practical tasks. We focus on text from two distinct domains: news articles from the Wall Street Journal, and scientific articles focusing on molecular biology. Adopting a task-based evaluation strategy, we consider the easy adaptability of the core framework to practical tasks that involve some extra-propositional aspect as a measure of its success. The computational tasks we consider include hedge/uncertainty detection, scope resolution, negation detection, biological event extraction, and attribution resolution. Our competitive results in these tasks demonstrate the viability of our proposal

Resistance and Production in the Ruins of Pedagogy and Student Writing

This thesis is an examination of the (im)possibility of the critical in pedagogy and student writing. More specifically, using Foucault’s concept of governance, and his genealogical problematization of power/knowledge which animates and constrains the present, it interrogates normative understandings of ‘the critical’ as a criterion against which practice and language are evaluated in the academy. A poststructuralist, materialist approach to understanding academic work and its subjects is developed and employed in exploring the ‘ruins’ of pedagogy and student writing, where the metaphor of ‘ruins’ refers to ‘the crumbling edifice of Enlightenment values’ (Maclure 2011:997). Foucault’s methods and sensitivities, and Derrida’s understanding of the ‘event’ of writing, are conjointly put to work to problematise the operations of power in the governance, administration and legitimation of hegemonic understandings of ‘the critical’ in higher education. Deploying as analytical notions and tools Foucault’s understanding of power as multiple forces of resistance and consent, or as an immanence in our doings which operates in minute, micro-physical heterogeneous ways, this thesis scrutinizes the ways the present of critical pedagogical practice, and undergraduate student writing in the field of intercultural communication, is produced and conditioned from within. The ineluctable oscillation between resistance and consent in such presents puts into question the post- possibility of ‘the critical’, here understood as ‘the right to difference, variation and metamorphosis’ (Derrida 2006:87) within the ‘matrix of calculabilities’ in the university (Ball & Olmedo 2012:103). This question is put into context in relation to the wider field of pedagogical and student writing practices. Using close reading of student assessment texts, contingent ‘micro-practices of resistance’ are considered for ways they fleetingly keep openness in play, and proposed as one tentative way forward for a post-critical praxis of literacy pedagogy and writing

Poiesis in/between the Transferential Matrix: Insight, Imagination and the Relational Interpretation

The most important question for the Psychoanalytic Process Research is presumably what Mitchell calls the problem of “bootstrapping” the transferential matrix: how do the members of the dyad manage to disengage from being ‘heard’ according to old or unsuitable affective categories? On the grounds of a bi-phasic Conceptual and in-depth Analysis of the Psychoanalytic Complexity literature, I construct a minimal model of the psychoanalytic process as a theoretical context for conducting Process Research. According to the ‘story’ that I have read in the literature four main themes describe the process: a) the gradual emergence of a ‘phenomenological’ language that facilitates the flow of experience, b) the coupling, synchronicity and coordination of analyst and analysand, in ‘phase’ and ‘anti-phase’ at several levels, c) the shifting of the mental states and the thin and delicate slicing and sampling of experience that actualizes the emergence of mental objects and finally, d) Scaling that involves all those ‘mental’ processes that correct for the excesses or the deficiencies that are made evident during the shifting of mental states. Experience is generated as we ‘couple and shift’, and generative tensions appear as we ‘scale’ through this coupling and shifting process. Enactments, role-responsive transferences and countertransferences, testing of the transference and alliance or communication ruptures appear as coupled oscillating patterns that have both a repetitive and a developmental dynamic. Regarding the question of how we should study ‘Coupling, Shifting and Scaling’ I propose the adoption of an Enactivist epistemological framework which perceives the mind not as the workings of a representational machine but as a living process and the expression of an embodied living organism which in a “precarious” state of “needful freedom” (Jonas, in Thompson, 2007) strives to make sense of its environment. On the grounds of this framework I defend the view that we should study Scaling as an expression of the ‘radical dialogicality’ of the human mind that underlies the ‘structuring of experience’. I examine this ‘radical dialogicality’ at the level of inter-hemispheric differences, psychopathology and the enactive structuring of experience and the horizon of affective affordances in the clinical process. Finally, on the grounds of this conceptual analysis and its application to a case-study, I try to defend the view that, adopting relevant “dialogical” and micro-analytic methodological tools, we can achieve an appropriate level of ‘resolution’ so as to study “bootstrapping” at the moment-to-moment shifts in the experiential states or the shifts in attitudes that appear at bifurcation points in the system’s evolution. Through Scaling, the clinical dyad strives for a “maximum grip” of those experiential dimensions that carry the potential to expand the shared reality as a generative field and engage those surfaces of experience that bridge lost connections and separations, by fractalizing the dimensionality of the generative space. A detailed examination of the Scaling processes may bring us closer to a better understanding of the problem of “bootstrapping”

The value of home narratives in shaping identities and making sense of experiences in a host culture

Since the late 1990s Finland had experienced an influx of foreign students and workforce from African countries. The demographic scene of so far homogenous and predominantly white Finland had changed. Finland became a lot more diversified culturally than it was when I first arrived in 1990. With this diversification, the cultural scene of predominantly white Finland created not only opportunities, but also challenges. Finns as well as foreigners experienced multiculturalism first- hand, both within organisations and in everyday life. The foreigners from African countries brought with them their cultures, but also had to adapt to the demands of their new host culture in Finland. In addition, Deloitte Global Human Capital Trends report of 2019 calls for the need to reinvent business concepts with the focus on organisations shifting their focus and the need to develop social enterprise, encompassing such matters as diversity leadership, diversified work force, flexibility, teamwork, and mobility both within organisations and geographical locations. These developments called for developing strategies that tap the skilled intellectual and cultural capital they wished to attract and create multicultural working environments that retain the talent. In view of the above-mentioned demographic changes in Finland, as well as the global demographic trends, my qualitative, exploratory research investigates 1) How do black educated professionals, from selected African countries, experience their life and work in a foreign host culture in Finland? 2) To what extent do their native cultures inform their understanding of their experiences of the host culture? 3) How do their experiences influence their cultural identities? The study adopted Interpretative Phenomenological Analysis (IPA) and incorporated elements of Narrative Analysis (NA) as its methodological underpinning. By using IPA, through the voices of ten participants (five females and five males) the study attempted to understand the experiences of educated professionals of African origin in the Finnish host culture. By providing the insights into the experiences of the participants, the study provides a basis for new hybrid epistemologies through reconceptualisation of the Western working cultures and discourses that render some people worthier than others. It also questions the prevailing western ontological perception of the ‘other’. The data was collected through semi-structured life-story interviews. The data was analysed first by identifying themes of the interviews. This was followed by an analysis using elements of interpretative poetics to gain access to deeper levels by identifying story threads, forms of address, and the positioning of the narrator. The findings of the study showed that the sensemaking in the foreign host culture of the participants was informed by the values and the influence of their role models of their respective home cultures. Females drew from strong native female identity archetypes rooted in their home cultures, which resulted in a reinforcement of their strong sense of black woman identity in the host culture. Males drew from an identity of an educated man who excels and achieves his goals, informed by the values of fairness and justice, which resulted in the development of a compromised sense of identity in the host culture, especially in the work environment. The study contributes to Jack et al.’s (2011) and Frenkel and Shenhav’s (2006) discussion on postcolonial interrogative space as well as postcolonial identity by proposing such concepts as duality of being, belonging ambivalence, validation ambiguity, free colonial woman. It also expands the contextual landscape of the previous studies (see Chapter 2) by providing insights into the cultural context of Finland, a country relatively new to cultural diversity. The study makes a contribution to the conceptualisation of the positive identity validation within the Social Identity Theory. Contrary to SIT’s claim, that through negotiations of the tensions people might experience difficulties with self-categorisation, thus leading to diminished self- esteem, the findings of the study suggest the opposite to take place. Drawing on Strong Black Woman schema, the findings show evidence of self-categorisations as sources of positive validation, enhanced self-esteem, and reaffirmation of sense of self, what I coined as positive identity validation. In addition, the study contends SIT’s premise, that people’s self-esteem is enhanced by self- categorisation within social groups to which they belong. It proposes that self-categorisation can create an accentuation of the perceived differences between people’s selves (black) and the other (white) in-group members. Therefore, contrary to SIT, people’s group belonging does not produce enhancement to their self- esteem, nor does it strengthen their self-efficacy. Methodologically, the study widens the application of Interpretive Phenomenological Analysis, primarily used in psychology. By combining IPA with elements of interpretive poetics (Narrative Analysis) it shows how researchers from other fields, not only practitioners of psychology, can apply IPA in their studies. The study also disrupts the epistemic colonisation and cultural imperialism, which, according to Jack et al. (2011) is at the heart of MOS. By combining the cultural background of the researcher (not purely western, sharing socio-historical commonalities with the participants) the study offers an account which does not fall strictly into western classifications. It provides a qualitative, interpretive investigation which provides insights into the cultural values of the participants, and it draws from sources published not exclusively within the US or western contexts. Within Weick’s (1995) framework of sensemaking, my study contests the claim that individuals change and adopt various identities according to the demands of situations. It introduces interrelatedness of the sense of self, performance and representation of the identity as influenced by power, which makes changes of identities limited in the case of individuals with black skin. The study is ideographic, thus giving attention to individual cases. It focuses on the value of individuals who form the basis of each culture and organisation. The knowledge of the cultural values that drive peoples’ behaviour creates a platform where successful and conflict-free communication can develop. In Finland, where the demographic structure has become more culturally diverse, the issues of cultural inclusion and participation are of great importance. Finally, the study also provides a deeper understanding of the meaning and value of diversified cultural identities. This knowledge creates a platform for understanding and acknowledging the value of cultural diversity. This acknowledgment itself helps reformulate the ‘other’ and ‘subaltern’ in Western discourse. It creates a discourse through which the analytical dualisms of tradition/modernity and development/underdevelopment will be rendered obsolete and substituted by a new hybrid epistemology (Frenkel and Shenhav, 2006). It suggests ways in which concepts such as lower level of material consumption, strong kinship ties, and social commitment (Zein-Elabdin, 2009) will be viewed as serviceable ethics. This will help reconceptualise working cultures of Western organisations, as well as understand non-Western ways

The Work of Communication

The Work of Communication: Relational Perspectives on Working and Organizing in Contemporary Capitalism revolves around a two-part question: "What have work and organization become under contemporary capitalism—and how should organization studies approach them?" Changes in the texture of capitalism, heralded by social and organizational theorists alike, increasingly focus attention on communication as both vital to the conduct of work and as imperative to organizational performance. Yet most accounts of communication in organization studies fail to understand an alternate sense of the "work of communication" in the constitution of organizations, work practices, and economies. This book responds to that lack by portraying communicative practices—as opposed to individuals, interests, technologies, structures, organizations, or institutions—as the focal units of analysis in studies of the social and organizational problems occasioned by contemporary capitalism. Rather than suggesting that there exists a canonically "correct" route communicative analyses must follow, The Work of Communication: Relational Perspectives on Working and Organizing in Contemporary Capitalism explores the value of transcending longstanding divides between symbolic and material factors in studies of working and organizing. The recognition of dramatic shifts in technological, economic, and political forces, along with deep interconnections among the myriad of factors shaping working and organizing, sows doubts about whether organization studies is up to the vital task of addressing the social problems capitalism now creates. Kuhn, Ashcraft, and Cooren argue that novel insights into those social problems are possible if we tell different stories about working and organizing. To aid authors of those stories, they develop a set of conceptual resources that they capture under the mantle of communicative relationality. These resources allow analysts to profit from burgeoning interest in notions such as sociomateriality, posthumanism, performativity, and affect. It goes on to illustrate the benefits that investigations of work and organization can realize from communicative relationality by presenting case studies that analyze (a) the becoming of an idea, from its inception to solidification, (b) the emergence of what is taken to be the "the product" in high-tech startup entrepreneurship, and (c) the branding of work (in this case, academic writing and commercial aviation) through affective economies. Taken together, the book portrays "the work of communication" as simultaneously about how work in the "new economy" revolves around communicative practice and about how communication serves as a mode of explanation with the potential to cultivate novel stories about working and organizing. Aimed at academics, researchers, and policy makers, this book’s goal is to make tangible the contributions of communication for thinking about contemporary social and organizational problems

MULTI-MODAL TASK INSTRUCTIONS TO ROBOTS BY NAIVE USERS

This thesis presents a theoretical framework for the design of user-programmable robots. The objective of the work is to investigate multi-modal unconstrained natural instructions given to robots in order to design a learning robot. A corpus-centred approach is used to design an agent that can reason, learn and interact with a human in a natural unconstrained way. The corpus-centred design approach is formalised and developed in detail. It requires the developer to record a human during interaction and analyse the recordings to find instruction primitives. These are then implemented into a robot. The focus of this work has been on how to combine speech and gesture using rules extracted from the analysis of a corpus. A multi-modal integration algorithm is presented, that can use timing and semantics to group, match and unify gesture and language. The algorithm always achieves correct pairings on a corpus and initiates questions to the user in ambiguous cases or missing information. The domain of card games has been investigated, because of its variety of games which are rich in rules and contain sequences. A further focus of the work is on the translation of rule-based instructions. Most multi-modal interfaces to date have only considered sequential instructions. The combination of frame-based reasoning, a knowledge base organised as an ontology and a problem solver engine is used to store these rules. The understanding of rule instructions, which contain conditional and imaginary situations require an agent with complex reasoning capabilities. A test system of the agent implementation is also described. Tests to confirm the implementation by playing back the corpus are presented. Furthermore, deployment test results with the implemented agent and human subjects are presented and discussed. The tests showed that the rate of errors that are due to the sentences not being defined in the grammar does not decrease by an acceptable rate when new grammar is introduced. This was particularly the case for complex verbal rule instructions which have a large variety of being expressed
