This article addresses the incremental and decremental maintenance of the frequent pattern space. We conduct an in-depth investigation on how the frequent pattern space evolves under both incremental and decremental updates. Based on the evolution analysis, a new data structure, Generator-Enumeration Tree (GE-tree), is developed to facilitate the maintenance of the frequent pattern space. With the concept of GE-tree, we propose two novel algorithms, Pattern Space Maintainer+ (PSM+) and Pattern Space Maintainer− (PSM−), for the incremental and decremental maintenance of frequent patterns. Experimental results demonstrate that the proposed algorithms, on average, outperform the representative state-of-the-art …

Addressing Relationships Among Moral Judgment Development, Narcissism, And Electronic Media And Communication Devices, Meghan M. Saculla
Masters Theses & Specialist Projects
Recently, Thoma and Bebeau (2008) reported moral judgment developmental trends among various samples of undergraduates and graduates where increases in Personal Interests reasoning and decreases in Postconventional reasoning were observed. In an attempt to explain such trends, they cited recent trends in increased narcissism among college students (Twenge, Konrath, Foster, Campbell, & Bushman, 2008) and also noted that certain types of technological devices (i.e. social networking websites, cell phones, etc.) may have adverse effects social decision-making and self-presentation. The current study, therefore, addresses the relationships among moral judgment development, narcissism, and electronic media and communication devices (EMCD's). Analyses support that …

Ubiquitäres Computing – Vision Einer Von Informationstechnologie Durchdrungenen Welt, Michael Friedewald
Michael Friedewald
Das Ubiquitäre Computing hat seine Wurzeln in den wegweisenden Arbeiten von Mark Weiser, der bis zu seinem Tod 1999 als leitender Wissenschaftler am Xerox-Forschungszentrum im Silicon Valley tätig war. Er propagierte schon 1991 in einem visionären Artikel im »Scientific American« den allgegenwärtigen Com- puter, der unsichtbar und unaufdringlich den Menschen bei seinen Tätigkeiten unterstützt und ihn von lästigen Routineaufgaben weitestgehend befreit. Der Computer als sichtbares Gerät sollte nach Weisers Auffassung verschwinden, dessen informationsverarbeitende Funktionalität aber überall verfügbar sein. Heute scheinen wir auf dem Weg dahin schon weit vorangekommen zu sein.

This project stems from two intersecting strands. The statement, "I can always find out," neatly summarizes the intersection. Not surprisingly, it has two distinct but simultaneous meanings. The first, in which "always" means "every time," considers the ways in which the ability to find knowledge has become synonymous with expertise and examines the elements that have fostered this situation. In this regard, factors such as the range of software and hardware-from Wikipedia and FAQs to cellphones and Ipods-which anticipate or "think" for the user but also require constant updating are both rationale and outcome for their youthful consumers. When combined …

Computer Science and Engineering Faculty Publications
The seminar centered around problems which arise in the context of machine learning in dynamic environments. Particular emphasis was put on a couple of specific questions in this context: how to represent and abstract knowledge appropriately to shape the problem of learning in a partially unknown and complex environment and how to combine statistical inference and abstract symbolic representations; how to infer from few data and how to deal with non i.i.d. data, model revision and life-long learning; how to come up with efficient strategies to control realistic environments for which exploration is costly, the dimensionality is high and data …

Trypanosoma cruzi is a protozoan parasite that causes Chagas disease or American trypanosomiasis, which is the leading cause of death in Latin America. The primary objective of this study is to create an ontology-driven information infrastructure to support parasite researchers in identifying gene knockout, vaccination, or drug targets for T. cruzi. This involves querying across multiple datasets from diverse sources, such as proteome, pathway, internal lab data, etc. that are often represented in heterogeneous formats. To address this, a multi-ontology parasite knowledge repository (PKR) is being created with an intuitive graphical query interface called Cuebee. The PKR is underpinned by …

Trust is an amorphous concept that is becoming Increasingly important in many domains, such as P2P networks, E-commerce, social networks, and sensor networks. While we all have an intuitive notion of trust, the literature is scattered with a wide assortment of differing definitions and descriptions; often these descriptions are highly dependent on a single domain or application of interest. In addition, they often discuss orthogonal aspects of trust while continuing to use the general term “trust”. In order to make sense of the situation, we have developed an ontology of trust that integrates and relates its various aspects into a …

The ability to rise from a chair is an important parameter to assess the balance deficits of a person. In particular, this can be an indication of risk for falling in elderly persons. Our goal is automated assessment of fall risk using video data. Towards this goal, we present a simple yet effective method of detecting transition, i.e. sit-to-stand and stand-to-sit, from image frames using fuzzy clustering methods on image moments. The technique described in this paper is shown to be robust even in the presence of noise and has been tested on several data sequences using different subjects yielding …

A Heuristic Algorithm For Trust-Oriented Service Provider Selection In Complex Social Networks, Guanfeng Liu, Yan Wang, Mehmet A. Orgun, Ee Peng Lim
Research Collection School Of Computing and Information Systems
In a service-oriented online social network consisting of service providers and consumers, a service consumer can search trustworthy service providers via the social network. This requires the evaluation of the trustworthiness of a service provider along a certain social trust path from the service consumer to the service provider. However, there are usually many social trust paths between participants in social networks. Thus, a challenging problem is which social trust path is the optimal one that can yield the most trustworthy evaluation result. In this paper, we first present a novel complex social network structure and a new concept, Quality …

The LOD cloud has a potential for applicability in many AI-related tasks, such as open domain question answering, knowledge discovery, and the Semantic Web. An important prerequisite before the LOD cloud can enable these goals is allowing its users (and applications) to effectively pose queries to and retrieve answers from it. However, this prerequisite is still an open problem for the LOD cloud and has restricted it to 'merely more data.' To transform the LOD cloud from 'merely more data' to 'semantically linked data' there are plenty of open issues which should be addressed. We believe this transformation of the …

As advances in communication technologies (CT) continue to shape modern life, it is critical study abroad professionals and faculty leaders contemplate the ways in which such technologies impact study abroad. This essay provides an argument for the value and utility of such contemplation through an in-depth examination of a short-term, faculty-led study abroad program and the three faculty who lead it. The authors provide reflective summaries of their own experiences with CT and study abroad and discuss the ways in which changes in CT resulted in changes to their own study abroad program including the integration of CT into academic …

Legal And Ethical Implications Of Corporate Social Networks, Gundars Kaupins, Susan Park
Management Faculty Publications and Presentations
Corporate social networking sites provide employees and employers with considerable opportunity to share information and become friends. Unfortunately, American laws do not directly address social networking site usage. The National Labor Relations Act, civil rights laws, and various common law doctrines such as employment at-will and defamation provide the pattern for future social networking laws. Ethical considerations such as productivity, security, goodwill, privacy, accuracy, and discipline fairness also affect future laws. Corporate policies on corporate social networking should balance the employer‘s and employee‘s interests. Existing laws and ethical issues associated with social networking should impact social networking policies related to …

Diffusion Models For Peer-To-Peer (P2p) Media Distribution: On The Impact Of Decentralized, Constrained Supply, Kartik Hosanagar, Peng Han, Yong Tan
Operations, Information and Decisions Papers
In Peer-to-Peer (P2P) media distribution, users obtain content from other users who already have it. This form of decentralized product distribution demonstrates several unique features. Only a small fraction of users in the network are queried when a potential adopter seeks a file and many of these users may even free-ride i.e. not distribute the content to others. As a result, generated demand may not always be fulfilled immediately. We present mixing models for product diffusion in P2P networks that capture decentralized product distribution by current adopters, incomplete demand fulfillment and other unique aspects of P2P product diffusion. The models …
