SEMANTIC DATA CLOUDING OVER THE WEBS
Very often, for business or personal needs, users require to retrieve, in a very fast way,
all the available relevant information about a focused target entity, in order to take
decisions, organize business work, plan future actions. To answer this kind of \u201centity\u201d-
driven user needs, a huge multiplicity of web resources is actually available, coming
from the Social Web and related user-centered services (e.g., news publishing, social
networks, microblogging systems), from the Semantic Web and related ontologies and
knowledge repositories, and from the conventional Web of Documents. The Ph.D.
thesis is devoted to define the notion of in-cloud and a semantic clouding approach for
the construction of in-clouds that works over the Social Web, the Semantic Web, and
the Web of Documents. in-clouds are built for a target entity of interest to organize all
relevant web resources, modeled as web data items, into a graph, on the basis of their
level of prominence and reciprocal closeness. Prominence captures the importance of
a web resource within the in-cloud, by distinguishing, also in a visual way \u201ca la tagcloud\u201d, how much relevant web resources are with respect to the target entity. The
level of closeness between web resources is evaluated using matching and clustering
techniques, with the goal of determining how similar web resources are to each other
and with respect to the target entity
Geographic Information Systems and Science
Geographic information science (GISc) has established itself as a collaborative information-processing scheme that is increasing in popularity. Yet, this interdisciplinary and/or transdisciplinary system is still somewhat misunderstood. This book talks about some of the GISc domains encompassing students, researchers, and common users. Chapters focus on important aspects of GISc, keeping in mind the processing capability of GIS along with the mathematics and formulae involved in getting each solution. The book has one introductory and eight main chapters divided into five sections. The first section is more general and focuses on what GISc is and its relation to GIS and Geography, the second is about location analytics and modeling, the third on remote sensing data analysis, the fourth on big data and augmented reality, and, finally, the fifth looks over volunteered geographic information.info:eu-repo/semantics/publishedVersio
Trend Mining
In terms of Information Retrieval (IR), a trend is defined as a topic area
that is growing in interest and utility over time. An example of a trend would
thus be the general topic financial crisis that started to appear on the
market in late 2007 and early 2008, or the Arab Spring that started to appear
on the news in 2011. Several approaches based on methods from text mining and
machine learning can be successfully applied to the problem of mining trends
in text collections. Among others, the most popular are probabilistic topic
models and diverse clustering methods. The weakness of the existing research
in automatic trend detection in texts lies in: 1\. inconsistency in the
definition of a trend 2\. lack of a general scientific approach for trend
mining 3\. lack of the integration of explicit knowledge and therefore the
difficulty in the interpretation of algorithm's results. The scientific
contribution of this research is contained in the suggestion to deal with the
trend detection from the perspective of trend mining that is being defined
here. As a solution for the problem of difficulty in the interpretation of the
results from the common trend detection techniques, this research proposes the
trend template that is a knowledge-based trend mining approach. Based on this
trend template, two directions of implementation are introduced: trend
ontology and trend-indication (the trend weighting method). The trend ontology
works as an a-priori model and enables the discovery of a trend structure in
the web documents corpus. Tests with this method on a test corpus show that
mining trends with an a-priori model while integrating explicit knowledge
leads to a better quality of results considering their interpretability. The
trend-indication approach is based on time-incorporating weighting methods for
selection of trend features from web documents. It enables the reduction of
features that are considered in the process of trend mining, and therefore
reduces the data so that only time-relevant information is considered for
further analysis. This method's results on our web document corpus show that
time-based weighting functions alone can help in discovering trend-relevant
features. Both the trend ontology and the trend-indication approaches are
implemented in the tremit tool (TREnd MIning Tool), a test tool developed for
this thesis, and are tested on a test corpus. The test corpus consists of
35,635 business news and 4,696 DAX (Deutscher Aktienindex - German stock
market) reports from German web sites in a late 2007 and early 2008. The
results are compared with the standard method results of a LDA-based topic
model and the k-means clustering algorithm on the same test corpus. Discussion
of the results is contained in the experimental part of the thesis.Ein Trend im Kontext des Information Retrievals (IR) ist ein Themengebiet, das
ĂŒber einen Zeitraum an Nutzwert und Interesse gewinnt, wie z. B. das
allgemeine Thema Finanzkrise im Zeitraum 2008-2012 oder Arabischer FrĂŒhling im
Zeitraum 2010-2011. Es gibt Verfahren, verankert in Bereichen des Data
Minings, Text Minings und des Maschinellen Lernens, die zur Lösung des
Problems der Trenderkennung in Texten herangezogen werden. Zu den oft
verwendeten gehören die probabilistischen Topic Models sowie verschiedene
Clusteringverfahren. Die Schwachstellen der existierenden Forschung ĂŒber
automatische Trenderkennung in Texten liegen in: 1\. inkonsistenten
Definitionen des Trends 2\. fehlendem wissenschaftlichen Ansatz des Trend
Mining 3\. fehlendem Bezug zum expliziten Wissen und damit schlechter
Interpretierbarkeit der Ergebnisse Der wissenschaftliche Beitrag dieser Arbeit
besteht in dem Vorschlag, die Forschung zur automatischen Trenderkennung aus
der Sicht des Trend Mining zu betrachten, dessen Definition in dieser Arbeit
vorgeschlagen wird. Als Lösung fĂŒr das Problem der schlechten
Interpretierbarkeit der Ergebnisse von gÀngigen Trenderkennungsalgorithmen
wird trend template vorgeschlagen, das ein wissensbasierter Ansatz fĂŒr trend
mining ist. Ausgehend von diesem trend template werden zwei
Implementierungsrichtungen gezeigt: die Trendontologie und das Trend-
Indication-Verfahren. Die Trendontologie funktioniert nach dem Prinzip eines A
-priori-Modells und ermöglicht die Entdeckung einer Trendstruktur in dem
Webdokumentenkorpus. Tests mit diesem Verfahren auf dem Testkorpus zeigen,
dass Trenderkennung mit einem A-priori-Modell unter Einbezug von explizitem
Wissen, zu qualitativ besseren Ergebnissen, vor allem in Hinsicht auf die
Interpretierbarkeit, fĂŒhrt. Das Trend-Indication-Verfahren baut auf den
zeitbasierten Gewichtungsfunktionen auf und konzentriert sich auf die
Selektion der Trend Features aus den Webdokumenten. Mithilfe dieses Verfahrens
wird die Dimension der zu untersuchenden Daten im Hinblick auf die
Trenderkennung sinnvoll reduziert und somit nur die zeitrelevante Information
aus den Texten fĂŒr weitere Analysen bereitgestellt. Die Tests mit diesem
Verfahren zeigen, dass zeitrelevante Trendbegriffe alleine durch geeignete
Gewichtungsfunktionen gut aufgedeckt werden. Beide Methoden werden in dem
tremit (TREnd MIning Tool), das fĂŒr diese Arbeit entwickelte Testtool,
implementiert und auf dem Testkorpus getestet. Der Testkorpus besteht aus
35.635 Wirtschaftsnachrichten und 4.696 DAX-Berichten des deutschsprachigen
Webs aus dem Zeitraum September 2007 bis April 2008. Die Ergebnisse werden mit
den Ergebnissen der gÀngigen Verfahren - LDA-basiertem Topic Model und k-means
Clustering - auf dem gleichen gleichen Korpus verglichen und im
Experimentierteil der Arbeit diskutiert und evaluiert
Understanding Addiction
The addiction literature is fraught with conceptual confusions, stalled debates, and an unfortunate lack of clear and careful attempts to delineate the phenomenon of addiction in a way that might lead to consensus. My dissertation has two overarching aims, one metaphysical and one practical.
The first aim is to defend an account of addiction as the systematic disposition to fail to control oneâs desires to engage in certain types of behaviors. I defend the inclusion of desires and impaired control in the definition, and I flesh out the notion of systematicity central to my dispositionalist framework. I engage the so-called âdisease vs. choiceâ debate, criticizing its presupposition that we are dealing here with a dichotomy and arguing that the movement towards a middle ground is the right track to take. I explain how the dispositionalist account can capture this middle ground and how it serves to expand upon existing views, in particular by filling in the metaphysical details.
The second aim is to show how the account I defend can help to unify the extant views and disciplinary perspectives in the literature. Both the dispositionalist aspect of my framework and the methodology adopted (applied ontology and systematic metaphysics) can move the literature towards both substantive and methodological unification. This will help to clear up conceptual confusions, resolve (or sometimes dissolve) apparently intractable disputes, situate different research perspectives with respect to each other, facilitate interdisciplinary dialogue, and help to frame important questions about addiction. Finally, I offer the beginnings of an ontology of addiction, which will provide a terminologically well-structured guide to the addiction literature in a way that will facilitate more effective and efficient communication and data management across disciplines
The electronic patient record: a linguistic ethnographic study in general practice
PhDElectronic Patient Records (EPRs) are in widespread use in UK general
practice. Although often taken-for-granted by clinicians, managers,
administrators and patients, there is limited understanding of how EPRs shape
care processes and healthcare interactions in this setting. The EPR is
ubiquitous in practice, but its social impact remains under-researched.
In this thesis I present a novel approach to examining the role of the EPR,
which draws on ethnography and discourse analysis. My work is based on eight
months of ethnographic observation in clinical and administrative areas of two
general practices. This included observation of clinical consultations, with videorecording
of the interpersonal interaction and contemporaneous screen capture
of the EPR. This opens up the âEPR-in-useâ to detailed scrutiny. In my analysis,
which draws particularly on the theoretical work of Goffman and Bakhtin, I pay
close attention to the detail of local action and interaction, whilst maintaining
sensitivity to the wider context of the general practice organisation. This makes
an original contribution to the emerging field of linguistic ethnography.
My analysis shows that the EPR contributes to shaping and regimenting
interactions and care practices in profound ways, both within the consultation
and more widely in general practice organisations. It creates new opportunities,
but also creates new demands and tensions. In particular, it sharpens the
tension between different ways of framing the patient â the patient as âindividualâ
and the patient as âone of a populationâ â the latter a more institutional version
of the patient. This creates what I have called a âdilemma of attentionâ for
clinicians engaged in patient care. I show ways in which the EPR contributes to
the bureaucratisation of care, the construction and circulation of authority within
and beyond the consultation, and the production of new notions of patienthood
and professional habitus in contemporary general practice
Lost in technology: Towards a critique of repugnant rights
Modern law is founded on an idea of justice that is made felt through rights and entitlements legal subjects enjoy. As such, for law and its idea of justice, rights are inherently good and therefore abundant. On encounter with injustice, it has become commonplace to inquire what laws and rights have been flouted, as if injustice would disappear in encounter with rights that encode justice. But what if no number of laws and rights â even with faultless execution â is up for the task of upholding what we deem just? In this dissertation, I look at the heart of this question, and find the lawâs answer not simply wanting but repugnant.
The research is animated by interaction of three topoi: personhood, technology, and international law. The first part concerns how these concepts are perceived in law and by those working with laws. As part of the unearthing of the conceptual ground rules, a trilemma between effectiveness, responsiveness, and coherence familiar from regulatory research and international law rears its head. I show how setting the priority on effective and responsive solutions has amounted to derogation of justice and diminishment of lawâs foundational entity, a natural person. I explore whether these outcomes could be avoided within liberal international law and answer my own question on the negative. I title this systematic outcome a theory of repugnant rights.
The latter part of the dissertation concerns technology, its regulation, and tendency to produce repugnant outcomes in international law. I focus on bio- and information technologies and their legal coding as tools to dismantle legal protection provided by our quality of being human. I will show how intricate legal norms break and remake us in ways that blur the boundaries between persons and things. Once something falls beyond or below the category of a person, its legal status can be warped, twisted, and turned â all while remaining at armâs length from the person it was once legally part of. Technological intervention to such things allows for effective circumvention of legal shelter provided by human rights, as I show through example of regulation of surrogacy and data storage.
To come to terms with the repugnancy, I seek shelter from anger as a transitory category that would enable us to move across the present impasse with rights. I suggest that at the very least international lawyers ought to be angry at quotidian horrors international law upholds. And through such anger overcome the misery and repugnancy of international law.---
Moderni oikeus pohjaa ajatukseen oikeudenmukaisuudesta, joka ilmenee oikeussubjektien nauttimien ja kĂ€yttĂ€mien oikeuksien vĂ€lityksellĂ€. NĂ€in ymmĂ€rrettynĂ€ oikeuden ja sen omaaman oikeudenmukaisuuden kĂ€sityksen kannalta oikeudet ovat itseisarvoisesti hyviĂ€, mikĂ€ selittÀÀ niiden suuren mÀÀrĂ€n. Kun kohtaamme epĂ€oikeudenmukaisuutta tapaamme kysyĂ€, mitĂ€ lakeja ja oikeuksia on loukattu, ikÀÀn kuin epĂ€oikeudenmukaisuus kaikkoaisi sen kohdatessa oikeuden sisĂ€ltĂ€mĂ€n oikeudenmukaisuuden idean. Mutta entĂ€ jos mikÀÀn mÀÀrĂ€ lakeja ja oikeuksia â edes tĂ€ydellisesti tĂ€ytĂ€ntöönpantuna â ei riitĂ€ puolustamaan oikeudenmukaisena pitĂ€mÀÀmme? VĂ€itöskirjassani kurkistan tĂ€mĂ€n kysymyksen ytimeen ja löydĂ€n vastauksen, joka ei ole ainoastaan riittĂ€mĂ€tön vaan myös vastenmielinen.
VÀitöksessÀni operoin oikeushenkilön, teknologian ja kansainvÀlisen oikeuden rajapinnoilla. VÀitökseni ensimmÀinen osa koskee sitÀ, kuinka oikeuden ja lakien parissa työskentelevÀt mieltÀvÀt nÀmÀ kÀsitteet. NÀiden kÀsitteiden tarkastelun yhteydessÀ havaitsen sÀÀntelytutkimuksesta ja kansainvÀlisestÀ oikeudesta tutun tehokkuuden, responsiivisuuden ja johdonmukaisuuden vÀlisen trilemman. Osoitan, miten tehokkaiden ja responsiivisten ratkaisujen asettaminen etusijalle on merkinnyt lipeÀmistÀ oikeudenmukaisuudesta ja samalla oikeuden keskeisen subjektin, luonnollisen henkilön, merkityksen pienentymistÀ. Tutkin, voitaisiinko tÀmÀ trilemma vÀlttÀÀ liberaalin kansainvÀlisen oikeuden puitteissa, ja vastaan omaan kysymykseeni kielteisesti. NimeÀn tÀmÀn tuloksen vastenmielisten oikeuksien teoriaksi.
VÀitöskirjan jÀlkimmÀinen osa kÀsittelee teknologiaa, sen sÀÀtelyÀ ja sen taipumusta tuottaa vastenmielisiÀ lopputuloksia kansainvÀlisessÀ oikeudessa. Tarkastelen lÀhemmin bio- ja informaatioteknologioita ja niiden oikeudellista sÀÀntelyÀ, sekÀ sitÀ millaisia vÀlineitÀ ne tarjoavat ihmisyyden tarjoaman oikeudellisen suojan purkamiseen. Osoitan kuinka monimutkaiset oikeudelliset normit rikkovat ja muokkaavat meitÀ tavoilla, jotka hÀmÀrtÀvÀt ihmisten ja asioiden vÀlisiÀ rajoja. Kun jokin ei ole enÀÀ henkilö, sen oikeudellista asemaa voidaan vÀÀristÀÀ, vÀÀntÀÀ ja kÀÀntÀÀ. Teknologinen puuttuminen tÀllaisiin esineisiin ja asioihin mahdollistaa ihmisoikeuksien tarjoaman laillisen suojan tehokkaan kiertÀmisen, kuten osoitan sijaissynnytyksen ja datan tallennuksen sÀÀntelyn kautta.
Vastauksena oikeuden vastenmielisyydelle haen suojaa vihasta. Viha tarjoaa sellaisen tilapÀisen kategorian, jonka avulla voimme vÀlttÀÀ havaitsemani oikeuksien umpikujan. Katson, ettÀ kansainvÀlisen oikeuden harjoittajien olisi vÀhintÀÀnkin oltava vihaisia kohdatessaan kansainvÀlisen oikeuden synnyttÀmiÀ ja mahdollistamia jokapÀivÀisiÀ kauhuja. Turvautumalla vihaan, jonka voimme myöhemmin asettaa sivuun, voisimme selÀttÀÀ kansainvÀlisen oikeuden surkeuden ja sen vastenmielisyyden

Biometrics
Biometrics uses methods for unique recognition of humans based upon one or more intrinsic physical or behavioral traits. In computer science, particularly, biometrics is used as a form of identity access management and access control. It is also used to identify individuals in groups that are under surveillance. The book consists of 13 chapters, each focusing on a certain aspect of the problem. The book chapters are divided into three sections: physical biometrics, behavioral biometrics and medical biometrics. The key objective of the book is to provide comprehensive reference and text on human authentication and people identity verification from both physiological, behavioural and other points of view. It aims to publish new insights into current innovations in computer systems and technology for biometrics development and its applications. The book was reviewed by the editor Dr. Jucheng Yang, and many of the guest editors, such as Dr. Girija Chetty, Dr. Norman Poh, Dr. Loris Nanni, Dr. Jianjiang Feng, Dr. Dongsun Park, Dr. Sook Yoon and so on, who also made a significant contribution to the book
