Effects Of Information And Machine Learning Algorithms On Word Sense Disambiguation With Small Datasets, Gondy Leroy, Thomas C. Rindflesch

CGU Faculty Publications and Research

Current approaches to word sense disambiguation use (and often combine) various machine learning techniques. Most refer to characteristics of the ambiguity and its surrounding words and are based on thousands of examples. Unfortunately, developing large training sets is burdensome, and in response to this challenge, we investigate the use of symbolic knowledge for small datasets. A naïve Bayes classifier was trained for 15 words with 100 examples for each. Unified Medical Language System (UMLS) semantic types assigned to concepts found in the sentence and relationships between these semantic types form the knowledge base. The most frequent sense of a word …

A Semiotics View Of Modeling Method Complexity – The Case Of Uml, Keng Siau, Y. Tian

Research Collection School Of Computing and Information Systems

Unified Modeling Language (UML) is the standard modeling language for object oriented system development. Despite its status as a standard, UML’s formal specification is fuzzy and its theoretical foundation is weak. Semiotics, the study of signs, provides us good theoretical foundation for UML research as UML graphical notations are some kinds of signs. In this research, we use semiotics to study the graphical notations in UML. We hypothesized that using iconic signs as UML graphical notations leads to more accurate representation and arouses fewer connotations than using symbolic signs. Since symbolic signs involve more learning efforts, we assume that expert …

Interactive Preferences And Decision-Theoretic Planning, Derek Williams, Kyle Bailey, Alex Dekhtyar, Judy Goldsmith, Beth Goldstein, Raphael Finkel, Joan Mazur

Computer Science and Software Engineering

We introduce a suite of interlinked software tools for eliciting preferences, doing decision-theoretic planning, and displaying the plans. The software allows a user to walk through possible trajectories, adjust preferences, and compare potential trajectories. This paper focuses on the elicitation process, the plan display, and interactions between the two.

Technology transfer is an important component of an economic development effort in communities, states, and nations. Understanding the process used to transfer technology is needed to promote policies that develop an effective infrastructure to encourage technology transfer. This paper uses qualitative and quantitative methodologies to examine managerial perceptions of the effects of government policies on the technology transfer process. The impacts of tax policies, environmental regulations, health and safety regulations, labor regulations, international trade regulations, and the differences in regulations between countries are studied. Items used to …

Xtagger: A New Approach To Authoring Document-Centric Xml, Ionut E. Iacob, Alex Dekhtyar

Computer Science and Software Engineering

The process of authoring document-centric XML documents in humanities disciplines is very different from the approach espoused by the standard XML editing software with the data-centric view of XML. Where data-centric XML is generated by first describing a tree structure of the encoding and then providing the content for the leaf elements, document-centric encodings start with content which is then marked up. In the paper we describe our approach to authoring document-centric XML documents and the tool, xTagger, originally developed for this purpose within the Electronic Boethius project, otherwise enhanced within the ARCHway project, an interdisciplinary project devoted to development …

A Framework For Processing Complex Document-Centric Xml With Overlapping Structures, Ionut E. Iacob, Alex Dekhtyar

Computer Science and Software Engineering

Management of multihierarchical XML encodings has attracted attention of a number of researchers both in databases [8] and in humanities[10]. Encoding documents using multiple hierarchies can yield overlapping markup. Previously proposed solutions to management of document-centric XML with overlapping markup rely on the XML expertise of humans and their ability to maintain correct schemas for complex markup languages.

We demonstrate a unified solution for management of complex, multihierarchical document-centric XML. Our framework includes software for storing, parsing, in-memory access, editing and querying, multihierarchical XML documents with conflicting structures.

On Assigning Place Names To Geography Related Web Pages, Wenbo Zong, Dan Wu, Aixin Sun, Ee Peng Lim, Dion Hoe-Lian Goh

Research Collection School Of Computing and Information Systems

In this paper, we attempt to give spatial semantics to web pages by assigning them place names. The entire assignment task is divided into three sub-problems, namely place name extraction, place name disambiguation and place name assignment. We propose our approaches to address these sub-problems. In particular, we have modified GATE, a well-known named entity extraction software, to perform place name extraction using a US Census gazetteer. A rule-based place name disambiguation method and a place name assignment method capable of assigning place names to web page segments have also been proposed. We have evaluated our proposed disambiguation and assignment …

Sharing The Big Apple : A Survey Study Of People, Place And Locatability, Samer Nadim Karam

Theses

Over the past half century social trends and new technologies have weakened local social ties and thus, the fabric of civil society itself. Mobile location-aware community systems offer one path to redress these problems by enhancing community cohesion and the formation of social capital by helping people to meet each other and coordinate their actions. However, little is known about the general population's desire and attitude towards these systems.

The design space described by the People-to-People-to-Geographical-Places Framework (P3-Framework), was used to guide a survey study of the impact of 'place' on people's social information needs and their willingness to share …

Semantic Parsing Of Java I/O In Novice Programs For An Online Grading System, William Madden

Theses, Dissertations and Culminating Projects

Beginning programming students have access to sophisticated development tools that enable them to write syntactically correct code in a straightforward manner. However, code that compiles and runs can still execute poorly, or with unintended results. We present a tool, based on an open-source parser-generation product written in Java, that performs semantic analysis of novice Java code. Specifically, the present investigation concerns the semantics of Java output methods, particularly when they are enclosed within iterative structures in the language. The effort will be to guard against threats that such methods pose to system integrity and performance, intercepting them prior to runtime. …

Event-Driven Document Selection For Terrorism, Zhen Sun, Ee Peng Lim, Kuiyu Chang, Teng-Kwee Ong, Rohan Kumar Gunaratna

Research Collection School Of Computing and Information Systems

In this paper, we examine the task of extracting information about terrorism related events hidden in a large document collection. The task assumes that a terrorism related event can be described by a set of entity and relation instances. To reduce the amount of time and efforts in extracting these event related instances, one should ideally perform the task on the relevant documents only. We have therefore proposed some document selection strategies based on information extraction (IE) patterns. Each strategy attempts to select one document at a time such that the gain of event related instance information is maximized. Our …

An Information Extraction Approach To Reorganizing And Summarizing Specifications, Krishnaprasad Thirunarayan, Aaron Berkovich, Dan Z. Sokol

Kno.e.sis Publications

Materials and Process Specifications are complex semi-structured documents containing numeric data, text, and images. This article describes a coarse-grain extraction technique to automatically reorganize and summarize spec content. Specifically, a strategy for semantic-markup, to capture content within a semantic ontology, relevant to semi-automatic extraction, has been developed and experimented with. The working prototypes were built in the context of Cohesia's existing software infrastructure, and use techniques from Information Extraction, XML technology, etc.

Video Summarization And Scene Detection By Graph Modeling, Chong-Wah Ngo, Yu-Fei Ma, Hong-Jiang Zhang

Research Collection School Of Computing and Information Systems

In this paper, we propose a unified approach for video summarization based on the analysis of video structures and video highlights. Two major components in our approach are scene modeling and highlight detection. Scene modeling is achieved by normalized cut algorithm and temporal graph analysis, while highlight detection is accomplished by motion attention modeling. In our proposed approach, a video is represented as a complete undirected graph and the normalized cut algorithm is carried out to globally and optimally partition the graph into video clusters. The resulting clusters form a directed temporal graph and a shortest path algorithm is proposed …

Negotiation Of Software Requirements In An Asynchronous Collaborative Environment, Catherine Lowry Campbell

Dissertations

The effect of task structure and negotiation sequence on collaborative software requirements negotiation is investigated. This work began with an extensive literature review that focused on current research in collaborative software engineering and, in particular, on the negotiation of software requirements and the requisite collaboration for the development of such requirements. A formal detailed experiment was then conducted to evaluate the effects of negotiation sequence and task structure in an asynchronous group meeting environment. The experiment tested the impact of these structures on groups negotiating the requirements for an emergency response information system. The results reported here show that these …

Pattern Discovery In Structural Databases With Applications To Bioinformatics, Sen Zhang

Dissertations

Frequent structure mining (FSM) aims to discover and extract patterns frequently occurring in structural data such as trees and graphs. FSM finds many applications in bioinformatics, XML processing, Web log analysis, and so on. In this thesis, two new FSM techniques are proposed for finding patterns in unordered labeled trees. Such trees can be used to model evolutionary histories of different species, among others.

The first FSM technique finds cousin pairs in the trees. A cousin pair is a pair of nodes sharing the same parent, the same grandparent, or the same great-grandparent, etc. Given a tree T, our …

Meteor-S Wsdi: A Scalable P2p Infrastructure Of Registries For Semantic Publication And Discovery Of Web Services, Kunal Verma, Kaarthik Sivashanmugam, Amit P. Sheth, Abhijit Patil, Swapna Oundhakar, John Miller

Kno.e.sis Publications

Web services are the new paradigm for distributed computing. They have much to offer towards interoperability of applications and integration of large scale distributed systems. To make Web services accessible to users, service providers use Web service registries to publish them. Current infrastructure of registries requires replication of all Web service publications in all Universal Business Registries. Large growth in number of Web services as well as the growth in the number of registries would make this replication impractical. In addition, the current Web service discovery mechanism is inefficient, as it does not support discovery based on the capabilities of …

The Ims New Researchers' Survival Guide, Naomi Altman, David Banks, Janis Hardwick, Kathryn Roeder, Peter Craigmile, Johanna S. Hardin, Mayetri Gupta

Pomona Faculty Publications and Research

Statistics is a wonderfully diverse profession and graduate students making career choices have many options — especially in light of the dearth of students moving into the statistical sciences today. The three main career paths at the PhD level are in academics, industry/business and government. Each of these job types offers its own mix of intellectual challenges, financial reward, pressure and security. How a new researcher selects (or is selected by) a specific occupation in the statistical sciences sometimes seems more a function of luck than of conscious decision making. This consideration was one of the first concerns addressed by …

Taxaminer: An Experimentation Framework For Automated Taxonomy Bootstrapping, Vipul Kashyap, Cartic Ramakrishnan, Christopher Thomas, Amit P. Sheth

Kno.e.sis Publications

Construction of domain ontologies on the semantic web is a human and resource intensive process, efforts to reduce which are crucial for the Semantic Web to scale. We present a framework for automated taxonomy construction, that involves: (a) generation of a cluster hierarchy from a document corpus using statistical clustering and NLP techniques; (b) extraction of a topic hierarchy from this cluster hierarchy; and (c) assignment of labels to nodes in the topic hierarchy. Metrics for estimating topic hierarchy quality and parameters of an experimentation framework are identified. MEDLINE was the document corpus and MeSH thesaurus was the gold standard.

Interfacing Agents With Natural Language, Jared Allen

Inquiry: The University of Arkansas Undergraduate Research Journal

Technology is leading us to a world where computers are everywhere. A new breed of machines capable of sensing and reacting to stimuli in the real world is under development. Unfortunately, these new, powerful devices can oftentimes be difficult for the average person to understand. It is imperative that an easy to use interface be implemented to usher in this new world. Natural language (speech) would be an ideal solution. However, it has proven implausible on a large scale. A Menu-Based Natural Language Interface (MBNLI) could retain the intuitiveness of speech, while eliminating the obstacles impeding implementation. This research paper …

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 …

Roads Diverging In Yellow Woods: New Paths For Ecological And Environmental Anthropology, Sarah Hitchner

Ecological and Environmental Anthropology (University of Georgia)

Anthropology is at a crossroads; perhaps it always has been. Because it is such a broad discipline, there has always been debate among anthropologists over its role inside and outside of academia. There are often tensions between the paradigms of theory and practice, modernism and postmodernism, constructionism and deconstructionism, scaling up and scaling down, and many other seeming dichotomies that really contain many shades of gray. Anthropology has been called “the most humanistic of the sciences, and the most scientific of the humanities.” We anthropologists should take this phrase as a compliment, and each strive to find our own niche …
