Transform Based And Search Aware Text Compression Schemes And Compressed Domain Text Retrieval, Nan Zhang

Electronic Theses and Dissertations

In recent times, we have witnessed an unprecedented growth of textual information via the Internet, digital libraries and archival text in many applications. While a good fraction of this information is of transient interest, useful information of archival value will continue to accumulate. We need ways to manage, organize and transport this data from one point to the other on data communications links with limited bandwidth. We must also have means to speedily find the information we need from this huge mass of data. Sometimes, a single site may also contain large collections of data such as a library database, …

From Semantic Search & Integration To Analytics, Amit P. Sheth

Kno.e.sis Publications

Semantics is seen as the key ingredient in the next phase of the Web infrastructure as well as the next generation of enterprise content management. Ontology is the centerpiece of the most prevalent semantic technologies and provides the basis of representing, acquiring, and utilizing knowledge. With the availability of several commercial products and many research tools, specifications and increasing adoption of Semantic Web standards such as RDF for metadata and OWL for ontology representation, ontology-driven techniques and systems have already enabled a new generation of industry strength semantic applications. In particular, Semagix's Freedom has powered applications in leading verticals such …

Terminator Or Super Mario: Human/Computer Hybrids, Actual And Virtual, Noreen L. Herzfeld

Theology Faculty Publications

Is a human/computer hybrid feasible: If so, in what ways would such hybridization affect our concept of what it means to be human? There are two forms of such hybridization, the actual and the virtual. Actual hybridization involves the implantation of mechanical devices in the human body. In actual hybridization the computer comes to us and to our body to enhance our functioning in our world. In virtual hybridization we go to the computer, projecting our minds into the world of cyberspace and being formed there. Perhaps the most common form of virtual hybridization is the immersion our children experience …

Support For High Performance Real-Time Collaboration Within The Naradabrokering Substrate, Shrideep Pallickara, Hasan Bulut, Pete Burnap, Geoffrey C. Fox, Ahmet Uyar, David Walker

Electrical Engineering and Computer Science - All Scholarship

The requirements for collaborative services, especially pertaining to order and delivery, are quite different compared to traditional distributed applications. The NaradaBrokering messaging substrate enables scalable, fault-tolerant, distributed interactions between entities, and is based on the publish/subscribe paradigm. The substrate also incorporates support for Grid and Web Service. More recently, we have incorporated services within the substrate which enable us to facilitate richer collaborative interactions. In this paper, we outline our rationale for incorporating these services and how these services interact with each other. We have conducted experiments related to profiling these services, and also on the performance and scaling of …

This paper provides a glimpse into the risk management methods, methodologies and techniques available to those who are responsible for software development projects by conducting a non-experimental content analysis. The findings reveal that risk management has not received sufficient attention and does not appear to be widely accepted within the software engineering …

Optimal Scheduling In A Queue With Differentiated Impatient Users, Amy Csizmar Dalal, Scott Jordan

Computer Science Faculty Work

We consider a M/M/1 queue in which the average reward for servicing a job is an exponentially decaying function of the job’s sojourn time. The maximum reward and mean service times of a job are i.i.d. and chosen from arbitrary distributions. The scheduler is assumed to know the maximum reward, service rate, and age of each job. We prove that the scheduling policy that maximizes average reward serves the customer with the highest product of potential reward and service rate.

Epics: A Service Learning Program At Butler University, Jonathan P. Sorenson, Panos K. Linos

Scholarship and Professional Work - LAS

In this paper we present our experiences teaching EPICS (Engineering Projects In Community Service) at Butler University, a small, private university, from within the Department of Computer Science and Software Engineering. The EPICS program began at Purdue University in 1995. The idea behind EPICS is to have undergraduate students earn college credit for working on long-term, multi-semester projects to benefit charity and non-profit organizations. The projects are student-driven, under faculty supervision. There are many good reasons for having an EPICS program in an undergraduate computer science major. It is excellent for leveraging knowledge from other areas of computer science such …

Enhancing Message Privacy In Wired Equivalent Privacy., Darshan Purandare

Electronic Theses and Dissertations

The 802.11 standard defines the Wired Equivalent Privacy (WEP) and encapsulation of data frames. It is intended to provide data privacy to the level of a wired network. WEP suffered threat of attacks from hackers owing to certain security shortcomings in the WEP protocol. Lately, many new protocols like WiFi Protected Access (WPA), WPA2, Robust Secure Network (RSN) and 802.11i have come into being, yet their implementation is fairly limited. Despite its shortcomings one cannot undermine the importance of WEP as it still remains the most widely used system and we chose to address certain security issues and propose some …

Access Games: A Game Theoretic Framework For Fair Bandwidth Sharing In Distributed Systems, Sudipta Rakshit

Electronic Theses and Dissertations

In this dissertation, the central objective is to achieve fairness in bandwidth sharing amongst selfish users in a distributed system. Because of the inherent contention-based nature of the distributed medium access and the selfishness of the users, the distributed medium access is modeled as a non-cooperative game; designated as the Access Game. A p-CSMA type medium access scenario is proposed for all the users. Therefore, in the Access Game, each user has two actions to choose from: "transmit" and "wait". The outcome of the Access Game and payoffs to each user depends on the actions taken by all the users. …

Ground Water Monitoring Using Smart Sensors, Srikanth Anumalla, Byrav Ramamurthy, David Gosselin

School of Computing: Conference and Workshop Papers

Groundwater resources are the principal source of drinking water for about 50 percent of the United States population. Groundwater resources in Nebraska are under increasing stress as there is a rapid growth in their usage. Water managers need more timely and accurate data to assess ground-water conditions to manage adverse situations such as drought and loss of pumpage in agriculture and domestic water supply. Currently groundwater researchers use stand-alone data logging equipment which is labor intensive and the method is not easily scalable if the number of logging locations increases. Commercially available real-time data monitoring solutions are either prohibitively costly …

The "Best K" For Entropy-Based Categorical Data Clustering, Keke Chen, Ling Liu

Kno.e.sis Publications

With the growing demand on cluster analysis for categorical data, a handful of categorical clustering algorithms have been developed. Surprisingly, to our knowledge, none has satisfactorily addressed the important problem for categorical clustering – how can we determine the best K number of clusters for a categorical dataset? Since categorical data does not have the inherent distance function as the similarity measure, traditional cluster validation techniques based on the geometry shape and density distribution cannot be applied to answer this question. In this paper, we investigate the entropy property of the categorical data and propose a BkPlot method for determining …

Building A Declarative Workflow Engine, Patrick Rushe

Theses

In the last two decades, technology has become available that not only allows certain activities of a business process to be automated, but also allows a business process itself to be automatically managed. A Workflow Management System assigns the work, passes it on, and tracks its progress. This technology is called Workflow. Workflow is the automation and formal management of a business process.

Many commercial and open-source Workflow Management Systems are available. However, the cost and technical difficulty in implementing either can be excessively high. The primary contribution of this work is to prove that building a workflow engine is …

A Generative Programming Approach To Interactive Information Retrieval: Insights And Experiences, Saverio Perugini, Naren Ramakrishnan

Computer Science Faculty Publications

We describe the application of generative programming to a problem in interactive information retrieval. The particular interactive information retrieval problem we study is the support for "out-of-turn interaction" with a website – how a user can communicate input to a website when the site is not soliciting such information on the current page, but will do so on a subsequent page. Our solution approach makes generous use of program transformations (partial evaluation, currying, and slicing) to delay the site’s current solicitation for input until after the user’s out-of-turn input is processed. We illustrate how studying out-of-turn interaction through a generative …

Establishing An Online Community Of Practice For Instructors Of English As A Foreign Language, Christopher M. Johnson

CCAC Theses and Dissertations

Communities of practice are entities that emerge for the purposes of learning and advancement of knowledge in a particular area. They emerge under all circumstances, even adverse situations. Because they can spawn great innovation and knowledge advancement, organizations need to cultivate and establish environments that allow them to develop. Currently, communities of practice have moved into the online world, in which their members use computer mediated communication to collaborate with each other.

In January, 2002, a virtual community was formed to enable teachers of English as a Foreign Language to collaborate on learning and applying various computing technologies in language …

A Uniform Approach To Logic Programming Semantics, Pascal Hitzler, Matthias Wendt

Computer Science and Engineering Faculty Publications

Part of the theory of programming and nonymonotonic reasoning concerns the study of fixed-point semantics for these paradigms. Several different semantics have been proposed during the last two decades, and some have been more successful and acknowledged than others. The rationales behind those various semantics have been manifold, depending on one's point of view, which may be that of a programmer or inspired by commonsense reasoning, and consequently the constructions which lead to these semantics are technically very diverse, and the exact relationships between them have not yet been fully understood. In this paper, we present a conceptually new method, …

Glyde - An Expressive Xml Standard For The Representation Of Glycan, Satya S. Sahoo, Christopher Thomas, Amit P. Sheth, Cory Andrew Henson, William S. York

Kno.e.sis Publications

The amount of glycomics data being generated is rapidly increasing as a result of improvements in analytical and computational methods. Correlation and analysis of this large, distributed data set requires an extensible and flexible representational standard that is also ‘understood’ by a wide range of software applications. An XML-based data representation standard that faithfully captures essential structural details of a glycan moiety along with additional information (such as data provenance) to aid the interpretation and usage of glycan data, will facilitate the exchange of glycomics data across the scientific community. To meet this need, we introduce GLYcan Data Exchange (GLYDE) …

Discovering Informative Subgraphs In Rdf Graphs, William H. Milnor, Cartic Ramakrishnan, Matthew Perry, Amit P. Sheth, John A. Miller, Krzysztof Kochut

Kno.e.sis Publications

Discovering patterns in graphs has long been an area of interest. In most contemporary approaches to such pattern discovery either quantitative anomalies or frequency of substructure is used to measure the interestingness of a pattern. In this paper we address the issue of discovering informative sub-graphs within RDF graphs. We motivate our work with an example related to Semantic Search. A user might pose a question of the form: ' What are the most relevant ways in which entity X is related to entity Y?' the response to which is a subgraph connecting X to Y. Relevance of the …

Towards More Comprehensive Information Retrieval Systems: Entity Extraction Using Xslt, Chris A. Mcmanigal

UNF Graduate Theses and Dissertations

One problem that exists in today's document management arena is the issue of retrieving information from electronic documents such as images, Microsoft Office documents, and e-mail. Specific data entities must be extracted from these documents so that the data can be searched and queried. This study presents a unique approach to extracting these entities: using Extensible Stylesheet Language Transformations (XSLT) to match patterns in text. Because XSLT is processed at run time, new XSLT templates can be created and used without having to recompile and redeploy the application. The specific implementation addressed in this project extracts entities from an image …

Risk Management In Crm Security Management, Mahdi Seify

Research outputs pre 2011

In an increasing competitive world, marketing survival can be depended simply on timely new information on customers and market trend. One of the most important strategies in CRM (Customer Relationship Management) is to capture enough information from customers and using this information carefully [Ryals , Tinsley]. Of course security of this information is very important in CRM data management [Bryan]. Data management is a method for scheduling and controlling data saving, recovering and processing. This activity has been done continually or periodically[Bryan]. Security level of this information depends on the security policy of the organization. CRM security policy is the …

Benchmarking E-Business Security: A Model And Framework, Graeme Pye, Matthew J. Warren

Research outputs pre 2011

The dynamic nature of threats and vulnerabilities within the E-business environment can impede online functionality, compromise organisational or customer information, contravene security implementations and thereby undermine online customer confidence. To negate these problems, E-business security has to become proactive, by reviewing and continuously improving security to strengthen E-business security measures and policies. This can be achieved through benchmarking the security measures and policies utilised within the E-business, against recognised information technology (IT) and information security (IS) security standards.

Architecture For Self-Estimation Of Security Level In Ad Hoc Network Nodes, Reijo Savola

Research outputs pre 2011

Inherent freedom due to a lack of central authority of self-organised mobile ad hoc networks introduces challenges to security and trust management. In these kinds of scenarios, the nodes themselves are naturally responsible for their own security – or they could trust certain known nodes, called “micro-operators”. We propose an architecture for security management in self-organising mobile ad hoc networks that is based on the nodes’ own responsibility and node-level security monitoring. The aim is to predict, as well as to monitor the security level concentrating on the principal effects contributing to it.
