Semantic Annotation And Search For Resources In The Next Generation Web With Sa-Rest, Ajith H. Ranabahu, Amit P. Sheth, Maryam Panahiazar, Sanjaya Wijeratne

Kno.e.sis Publications

SA-REST, the W3C member submission, can be used for supporting a wide variety of Plain Old Semantic HTML (POSH) annotation capabilities on any type of Web resource. Kino framework and tools provide support of capabilities to realize SA-RESTs promised value. These tools include (a) a browser-plugin to support annotation of a Web resource (including services) with respect to an ontology, domain model or vocabulary, (b) an annotation aware indexing engine and (c) faceted search and selection of the Web resources. At one end of the spectrum, we present Kino^E (aka Kino for Enterprise) which uses NCBO formal ontologies and …

A Domain Specific Language For Enterprise Grade Cloud-Mobile Hybrid Applications, Ajith H. Ranabahu, E. Michael Maximilien, Amit P. Sheth, Krishnaprasad Thirunarayan

Kno.e.sis Publications

Cloud computing has changed the technology landscape by offering flexible and economical computing resources to the masses. However, vendor lock-in makes the migration of applications and data across clouds an expensive proposition. The lock-in is especially serious when considering the new technology trend of combining cloud with mobile devices.

In this paper, we present a domain specific language (DSL) that is purposely created for generating hybrid applications spanning across mobile devices as well as computing clouds. We propose a model-driven development process that makes use of a DSL to provide sufficient programming abstractions over both cloud and mobile features. We …

Personalized Filtering Of The Twitter Stream, Pavan Kapanipathi, Fabrizio Orlandi, Amit P. Sheth, Alexandre Passant

Kno.e.sis Publications

With the rapid growth in users on social networks, there is a corresponding increase in user-generated content, in turn resulting in information overload. On Twitter, for example, users tend to receive uninterested information due to their non-overlapping interests from the people whom they follow. In this paper we present a Semantic Web approach to filter public tweets matching interests from personalized user profiles. Our approach includes automatic generation of multi-domain and personalized user profiles, filtering Twitter stream based on the generated profiles and delivering them in real-time. Given that users interests and personalization needs change with time, we also discuss …

Do Libraries Still Need Book Vendors And Subscription Agents?, Stephen Bosch, Christopher Sugnet, J. Cory Tucker, Lauren Corbett

Library Faculty Research

Digital content blurs the lines of traditional library acquisition workflows and organization. For example: link resolvers and the loading of order confirmation record files may be handled by systems staff in one organization and by technical services staff in another. Lines are being crossed between acquisitions and interlibrary loan functions, notably with electronic versions of theses and dissertations. Regardless of this blurring of lines, library staff use vendors still in acquiring content for the library collection. The reasons for using vendors have stood for decades, but are changes in the information industry having an impact? In the current environment, what …

The Myth Of Progress In Science: Dialectics, Distortion And Lysenkoism In The Soviet Union, Mark A. Ferguson Jr.

The Hilltop Review

The scientific controversy surrounding Lysenkoism is both unparalleled and well known amongst historians and philosophers of science (Joravsky 1970, McMullin 1987, Pollock 2009, Wolfe 2010). Yet, while this may be true for scholars and students a generation ago, I argue that the controversy of Lysenkoism is not widely known today. Particularly in political science, this historical period and phenomenon in the Soviet Union remains irrelevant or at least, inconsequential to the scientific study of politics.

Kino: A Generic Document Management System For Biologists Using Sa-Rest And Faceted Search, Ajith Harshana Ranabahu, Priti Parikh, Maryam Panahiazar, Amit P. Sheth

Kno.e.sis Publications

Document management has become an important consideration for the scientific community over the last decade. Human knowledge is central to many scientific domains, thus it is not possible to completely automate the document management process. Managing scientific documents require a semi-automatic approach to overcome issues of large volume, yet support the human participation in the process. In this paper we present Kino, a set of tools that streamline the document management process in life science domains. Kino is integrated with National Center for Biomedical Ontology (NCBO), providing scientists access to quality domain models. Annotated documents are indexed using a faceted …

Graduate Students’ Teaching Experiences Improve Their Methodological Research Skills, David F. Feldon, James Peugh, Briana E. Timmerman, Michelle A. Maher, Melissa Hurst, Denise Strickland, Joanna A. Gilmore, Cindy Stiegelmeyer

Instructional Technology and Learning Sciences Faculty Publications

Science, technology, engineering, and mathematics (STEM) graduate students are often encouraged to maximize their engagement with supervised research and minimize teaching obligations. However, the process of teaching students engaged in inquiry provides practice in the application of important research skills. Using a performance rubric, we compared the quality of methodological skills demonstrated in written research proposals for two groups of early career graduate students (those with both teaching and research responsibilities and those with only research responsibilities) at the beginning and end of an academic year. After statistically controlling for preexisting differences between groups, students who both taught and conducted …

Best Instructional Practices For Distance Education: A Meta-Analysis, Robin Michael Roberts

UNLV Theses, Dissertations, Professional Papers, and Capstones

Recent meta-analyses on the efficacy of distance education have concluded that no significant difference exists between face-to-face and distance education. At the same time, these meta-analyses noted that considerable heterogeneity existed between the individual studies used in the meta-analyses. Investigation of moderators responsible for that heterogeneity suggested that four things other than media delivery were primarily responsible for the majority of variation between study outcomes: methodological quality, instructor involvement, type of interaction, instructional methods and time-on-task. A comparative meta-analysis was performed to further investigate these moderators. Methodological quality, maturational differences in students and any undetermined media effects were controlled for …

Citizen Sensing: Opportunities And Challenges In Mining Social Signals And Perceptions, Amit P. Sheth

Kno.e.sis Publications

Millions of persons have become 'citizens' of an Internet- or Web-enabled social community. Web 2.0 fostered the open environment and applications for tagging, blogging, wikis, and social networking sites that have made information consumption, production, and sharing so incredibly easy. An interconnected network of people who actively observe, report, collect, analyze, and disseminate information via text, audio, or video messages, increasingly through pervasively connected mobile devices, has led to what we term citizen sensing. In this talk, we review recent progress in supporting collective intelligence through intelligent processing of citizen sensing. Key issues we cover in this talk are: - …

Measuring The Perceived Attributes Of Innovation: A Study Of Capacitive Switch Technology In Industrially Designed User Interface Controls, Aaron B. Stachewicz

Master's Theses and Doctoral Dissertations

The purpose of this research was to test the applicability of Rogers’ theory of innovation diffusion as it relates to measuring the perceived attributes of innovations of capacitive switch technology in user interface controls. This study used a Likert scale to collect data on the following perceived attributes of innovation including relative advantage, compatibility, trialability, demonstrability, visibility, ease of use, image, voluntariness, perceived risk, and perceived resources as outlined by Rogers (1995), Moore and Benbasat (1991), and Dupagne and Driscoll (2005). Results indicated whether a consumer is willing to accept capacitive switch innovation in industrially designed user interface controls.

Local Closed World Semantics: Keep It Simple, Stupid!, Adila Krishnadhi, Kunal Sengupta, Pascal Hitzler

Computer Science and Engineering Faculty Publications

A combination of open and closed-world reasoning (usually called local closed world reasoning) is a desirable capability of knowledge representation formalisms for Semantic Web applications. However, none of the proposals made to date for extending description logics with local closed world capabilities has had any significant impact on applications. We believe that one of the key reasons for this is that current proposals fail to provide approaches which are intuitively accessible for application developers at the same time are applicable, as extensions, to expressive description logics as SROIQ, which underlies the Web Ontology Language OWL.

In this paper, we propose …

Web Wisdom: An Essay On How Web 2.0 And Semantic Web Can Foster A Global Knowledge Society, Christopher Thomas, Amit P. Sheth

Kno.e.sis Publications

Admittedly this is a presumptuous title that should never be used when reporting on individual research advances. Wisdom is just not a scientific concept. In this case, though, we are reporting on recent developments on the web that lead us to believe that the web is on the way to providing a platform for not only information acquisition and business transactions but also for large scale knowledge development and decision support. It is likely that by now every web user has participated in some sort of social function or knowledge accumulating function on the web, many times without even being …

Automatic Domain Model Creation Using Pattern-Based Fact Extraction, Christopher Thomas, Pankaj Mehra, Wenbo Wang, Amit P. Sheth, Gerhard Weikum, Victor Chan

Kno.e.sis Publications

This paper describes a minimally guided approach to automatic domain model creation. The first step is to carve an area of interest out of the Wikipedia hierarchy based on a simple query or other starting point. The second step is to connect the concepts in this domain hierarchy with named relationships. A starting point is provided by Linked Open Data, such as DBPedia. Based on these community-generated facts we train a pattern-based fact-extraction algorithm to augment a domain hierarchy with previously unknown relationship occurrences. Pattern vectors are learned that represent occurrences of relationships between concepts. The process described can be …

Local Closed-World Reasoning With Description Logics Under The Well-Founded Semantics, Matthias Knorr, Jose Julio Alferes, Pascal Hitzler

Computer Science and Engineering Faculty Publications

An important question for the upcoming Semantic Web is how to best combine open world ontology languages, such as the OWL-based ones, with closed world rule-based languages. One of the most mature proposals for this combination is known as hybrid MKNF knowledge bases (Motik and Rosati, 2010 [52]), and it is based on an adaptation of the Stable Model Semantics to knowledge bases consisting of ontology axioms and rules. In this paper we propose a well-founded semantics for nondisjunctive hybrid MKNF knowledge bases that promises to provide better efficiency of reasoning, and that is compatible with both the OWL-based …

Management And Support Of Shared Integrated Library Systems, Jason Vaughan, Kristen Costello

Library Faculty Research

The University of Nevada, Las Vegas (UNLV) University Libraries has hosted and managed a shared integrated library system (ILS) since 1989. The system and the number of partner libraries sharing the system has grown significantly over the past two decades. Spurred by the level of involvement and support contributed by the host institution, the authors administered a comprehensive survey to current Innovative Interfaces libraries. Research findings are combined with a description of UNLV’s local practices to provide substantial insights into shared funding, support, and management activities associated with shared systems.

Comparing Components Of Flexography Printing For The Application Of Oxygen Barrier Inks On Films, Kasey Renee Reed

Graphic Communication

The purpose of this study is to appraise typical components used in flexographic printing to provide more knowledge on the use of printing with functional inks on filmic substrates when printing packaged products inline. An oxygen barrier coating was applied using different plate-screening technologies and anilox rolls. Comparing two plate-screening technologies and three different anilox rolls using oxygen permeability tests helped to conclude the optimum plate and anilox roll solution that best apply the ink for proper functionality of the coating, with minimal ink application as to reduce waste.

Further knowledge of printing oxygen barrier coatings inline will yield results …

Groundwater Research In Middle Earth, Thomas Lapoint

My senior project focused on studying saltwater intrusion in a coastal town of New Zealand. I feel lucky that I was able to travel to such a distant place, conduct research that was insightful and interesting, and immerse myself in an international culture all in the name of my education. As a Liberal Arts and Engineering Studies student, I aim to analyze not only the cultural differences and similarities that the foreign environment offers to me but also the detailed, technical, engineering aspect of my research. I believe that my education should be approached with a well rounded perspective that …

Creating An Environmental Placed Based Education At Norris Elementary, Ben Kittrell

Department of Environmental Studies: Undergraduate Student Theses

This study is focused on creating a place based education program. Place based education programs provide many benefits at the personal level with the students (PBEEC). The study was completed at Norris Elementary School where the students have access to the “Norris Forest” which is a planted forest with a walk way through the trees. Some of the trees are labeled for the students to identify and others are not. A graph of the unlabelled trees has been included for the students or the teachers to use.

This project incorporates activities that will engage the students in order to teach …

21rst Century Educational Farmstead, Trevis Carmichael

Department of Environmental Studies: Undergraduate Student Theses

When Europeans began settling in the United States, farmsteads were built across the Great Plains. Out of necessity, these had to function in a self-sufficient manner; meaning the people had to produce their own food, use local materials, and be energy efficient for their transportation. Parents had to teach their children how to do all of the practical work it took to maintain their lives. This was the foundation that America was built upon. Having completed the first decade of the 21st century, the time seems right for a mental re-settlement that follows some of those same principles. Teaching our …

What's Happening In Semantic Web ... And What Fca Could Have To Do With It, Pascal Hitzler

Computer Science and Engineering Faculty Publications

The Semantic Web is gaining momentum. Driven by over 10 years of focused project funding in the US and the EU, Semantic Web Technologies are now entering application areas in industry, academia, government, and the open Web.

The Semantic Web is based on the idea of describing the meaning - or semantics - of data on the Web using metadata - data that describes other data - in the form of ontologies, which are represented using logic-based knowledge representation languages. Central to the transfer of Semantic Web into practice is the Linked Open Data effort, which has already resulted in …

Trust Networks: Interpersonal, Social, And Sensor, Krishnaprasad Thirunarayan, Pramod Anantharam

Kno.e.sis Publications

Trust relationships occur naturally in many diverse contexts such as ecommerce, interpersonal interactions, social networks, sensor web, etc. As agents providing content and services become increasingly removed from the agents that consume them, the issue of robust trust inference and update become critical. Unfortunately, there is neither a universal notion of trust that is applicable to all domains nor a clear explication of its semantics or computation in many situations. In this beginner's level tutorial, we motivate the trust problem, explain the relevant concepts, summarize research in modeling trust and gleaning trustworthiness, and discuss challenges confronting us in this process.

Cyberbullying In Schools: A Research Study On School Policies And Procedures, Brian Wiseman

UNLV Theses, Dissertations, Professional Papers, and Capstones

A mixed-methods research design first using quantitative then qualitative data was used in order to explore what cyberbullying policies are being employed by principals in the state of Nevada. Electronic surveys were given to all 118 middle school principals in Nevada. Middle school was chosen because it is the age where cyberbullying behaviors are most prevalent. Out of the 118 surveys that were deployed, 66 principals responded. A series of independent t-tests and a chi-squared analysis was conducted using the survey data. The survey concluded by asking principals if they were willing to participate in a one-on-one interview regarding the …

The Practical Pev: Removing Barriers To Plug-In Electric Vehicle Charging And Ownership, Stephen Parry

Pomona Senior Theses

The paradigm of personal transportation is changing. Electric vehicles are here. The arrival of the Tesla Roadster, Nissan Leaf, and Chevy Volt has changed the way in which we have to think about the energy that fuels our transportation needs. As PEVs find their way into garages this year and especially in the coming years, the neighborhood, city, state, and regional electric infrastructure will take on a new importance for many people as their interactions with it become significantly more complex and intimate as a result of regular electric vehicle charging.
