A Modular Approach To Document Indexing And Semantic Search, Dhanya Ravishankar, Krishnaprasad Thirunarayan, Trivikram Immaneni

Kno.e.sis Publications

This paper develops a modular approach to improving effectiveness of searching documents for information by reusing and integrating mature software components such as Lucene APIs, WORDNET, LSA techniques, and domain-specific controlled vocabulary. To evaluate the practical benefits, the prototype was used to query MEDLINE database, and to locate domain-specific controlled vocabulary terms in Materials and Process Specifications. Its extensibility has been demonstrated by incorporating a spell-checker for the input query, and by structuring the retrieved output into hierarchical collections for quicker assimilation. It is also being used to experimentally explore the relationship between LSA and document clustering using 20-mini-newsgroups and …

Faster Owl Using Split Programs, Denny Vrandecic, Pascal Hitzler

Computer Science and Engineering Faculty Publications

Knowledge representation and reasoning on the Semantic Web is done by means of ontologies. While the quest for suitable ontology languages is still ongoing, OWL [5] has been established as a core standard. It comes in three flavours, as OWL Full, OWL DL and OWL Lite, where OWL Full contains OWL DL, which in turn contains OWL Lite. The latter two coincide semantically with certain description logics and can thus be considered fragments of first-order predicate logic.

Change And Connections: Passion And Organizational Change, Lynn Baird

E-JASL: Electronic Journal of Academic and Special Librarianship (1999-2009, Volumes 1-10)

First paragraph:

Librarians are change agents, working in an environment that requires us to be both leading and chasing change. We lead change when we create programs to meet our institutional needs based upon our knowledge of our students and faculty, available resources, and our awareness of the potential for what might be. We chase change when institutional priorities shift suddenly, in response to external forces such as funding or politics, or as a result of leadership transitions. Change can be invigorating for us as it keeps the creative juices flowing. Conversely, it can be exhausting when we feel as …

Cross-Disciplinary Prospecting: Educational Technology Offers Up Gold For Library And Information Science Curricula, Michael J. Miller

E-JASL: Electronic Journal of Academic and Special Librarianship (1999-2009, Volumes 1-10)

Abstract

This article provides an overview of the current trends in information and communication technology affecting library services and recommends how, because of these trends, library and information science (LIS) curricula should turn an inquisitive, interdisciplinary eye toward the field of educational technology. Gaps in current LIS professional training and practice are cited, curriculum standards in LIS and educational technology programs are described and compared, and examples are presented to demonstrate how educational technology pedagogy and practice help to successfully augment library skills, service, and practice.

Differences In Indexing Term Vocabularies And Agreement With Subject Specialists, John M. Weiner

E-JASL: Electronic Journal of Academic and Special Librarianship (1999-2009, Volumes 1-10)

Abstract

Index terms are an important component in considering a scientific topic. In a real sense, the indexing terms represent the vocabulary and language of the topic. Study of these critical terms has employed human and machine techniques. Computerized indexing systems can accurately and completely recognize terms, but the different strategies for organizing and evaluating the concepts (i.e., informative terms) and related issues may not be effective in accomplishing the desired descriptive actions. This paper explored the results of two computer supported approaches in indexing scientific documents against a background of simple random generation of informative terms in varying sized …

Papa's Got A Brand New (Virtual) Bag: Real-Time Chat And Reference Discourse, Darren Chase

E-JASL: Electronic Journal of Academic and Special Librarianship (1999-2009, Volumes 1-10)

Abstract

Many librarians agree that virtual reference has expanded the range of library reference services. Along with an expansion of reference service, virtual reference (especially real-time chat) has influenced reference discourse. Style characteristics of chat include its telegraphic brevity, its conversational and informal tone, and its tendency towards interview and exchange. A bedrock feature of traditional reference service is the reference interview-as this and other aspects of reference exchange are conversational, chat is exceptionally resonant within the continuum of reference services. The virtual reference librarian operates in a medium both familiar and leading-edge (a bridge between the traditional and the …

The result of this primary study paves the way of implementing campus portals in the Iranian higher education communities which will be paced by the …

Teaching Information Literacy To The Advanced Writing Class In Three Sessions, Colleen Kennedy

E-JASL: Electronic Journal of Academic and Special Librarianship (1999-2009, Volumes 1-10)

Introduction

As is the case at many universities, Northern Kentucky University’s Advanced Writing class is often thought of as the “Research Paper class.” Frequently, a research paper on a variety of topics is the capstone of the course and many of the other course assignments lead up to it. Students are usually brought to Steely Library for one class during the semester to be taught all the information competencies deemed necessary in one session. The classes are from 50 minutes to 75 minutes long.

The pilot program described here was a first attempt at an informal trial to determine whether …

Information And Communication Technologies And The Effects Of Globalization: Twenty-First Century “Digital Slavery” For Developing Countries—Myth Or Reality?, L. A. Ogunsola

E-JASL: Electronic Journal of Academic and Special Librarianship (1999-2009, Volumes 1-10)

Abstract

The main goal of this paper is to examine the ICT (Information and Communication Technology) revolution and the concept of globalization as they effect developing countries. Globalization as one of the reasons for possible widening of the gap between the poor and the rich nations was examined and the emerging concept of “digital slavery” was carefully evaluated. The wide gap in availability and use of ICTs across the world and the influences ICTs exert on globalization at the expense of developing countries were carefully examined and suggestions and necessary policies were offered for developing countries to leap-frog the industrialization …

On Embedding Machine-Processable Semantics Into Documents, Krishnaprasad Thirunarayan

Kno.e.sis Publications

Most Web and legacy paper-based documents are available in human comprehensible text form, not readily accessible to or understood by computer programs. Here, we investigate an approach to amalgamate XML technology with programming languages for representational purposes that can enhance traceability, thereby facilitating semiautomatic extraction and update. Specifically, we propose a modular technique to embed machine-processable semantics into a text document with tabular data via annotations, resulting sometimes in ill-formed XML fragments, and evaluate this technique vis a vis document querying, manipulation, and integration. The ultimate aim is to be able to author and extract human-readable and machine-comprehensible parts of …

Morphisms In Context, Markus Krotzsch, Guo-Qiang Zhang, Pascal Hitzler

Computer Science and Engineering Faculty Publications

Morphisms constitute a general tool for modelling complex relationships between mathematical objects in a disciplined fashion. In Formal Concept Analysis (FCA), morphisms can be used for the study of structural properties of knowledge represented in formal contexts, with applications to data transformation and merging. In this paper we present a comprehensive treatment of some of the most important morphisms in FCA and their relationships, including dual bonds, scale measures, infomorphisms, and their respective relations to Galois connections. We summarize our results in a concept lattice that cumulates the relationships among the considered morphisms. The purpose of this work is to …

A Semantic Template Based Designer For Semantic Web Processes, Ranjit Mulye, John A. Miller, Kunal Verma, Karthik Gomadam, Amit P. Sheth

Kno.e.sis Publications

The growing popularity of service oriented computing based on Web services standards is creating a need for paradigms to represent and design business processes. Significant work has been done in the representation aspects with regards to WSBPEL. However, design and modeling of business processes is still an open issue. In this paper, we present a novel designer for business processes, which allows for intuitive modeling of Web processes, as well as using a template based approach for semi-automatically integrating partners either at design time or at deployment time. This work has been done as part of the METEOR-S project, which …

Social Network Discovery By Mining Spatio-Temporal Events, Hady Lauw, Ee Peng Lim, Hwee Hwa Pang, Teck-Tim Tan

Research Collection School Of Computing and Information Systems

Knowing patterns of relationship in a social network is very useful for law enforcement agencies to investigate collaborations among criminals, for businesses to exploit relationships to sell products, or for individuals who wish to network with others. After all, it is not just what you know, but also whom you know, that matters. However, finding out who is related to whom on a large scale is a complex problem. Asking every single individual would be impractical, given the huge number of individuals and the changing dynamics of relationships. Recent advancement in technology has allowed more data about activities of individuals …

Web Service Semantics - Wsdl-S, Rama Akkiraju, Joel Farrell, John A. Miller, Meenakshi Nagarajan, Amit P. Sheth, Kunal Verma

Kno.e.sis Publications

Web services have primarily been designed for providing inter-operability between business applications. Current technologies assume a large amount of human interaction, for integrating two applications. This is primarily due to the fact that business process integration requires understanding of data and functions of the involved entities. Semantic Web technologies, powered by description logic based languages like OWL[1], aim to add greater meaning to Web content, by annotating the data with ontologies. Ontologies provide a mechanism of providing shared conceptualizations of domains. This allows agents to get an understanding of users’ Web content and greatly reduces human interaction for meaningful Web …

Ga-Facilitated Classifier Optimization With Varying Similarity Measures, Michael R. Peterson, Travis E. Doom, Michael L. Raymer

Kno.e.sis Publications

Genetic algorithms are powerful tools for k-nearest neighbors classification. Traditional knn classifiers employ Euclidian distance to assess neighbor similarity, though other measures may also be used. GAs can search for optimal linear weights of features to improve knn performance using both Euclidian distance and cosine similarity. GAs also optimize additive feature offsets in search of an optimal point of reference for assessing angular similarity using the cosine measure. This poster explores weight and offset optimization for knn with varying similarity measures, including Euclidian distance (weights only), cosine similarity, and Pearson correlation. The use of offset optimization …

Description Logic Programs: A Practical Choice For The Modelling Of Ontologies, Rudi Studer, York Sure, Pascal Hitzler

Computer Science and Engineering Faculty Publications

Knowledge representation using ontologies constitutes the heart of semantic technologies. Despite successful standardization efforts by the W3C, however, there are still numerous different ontology representation languages being used, and interoperability between them is in general not given. The problem is aggrevated by the fact that current standards lay foundations only and are well-known to be insufficient for the modelling of finer details. Thus, a plethora of extensions of the basic languages is being proposed, rendering the picture of ontology representation languages to be chaotic, to say the least. While semantic technologies start to become applicable and are being applied in …

Play And Technology:A Study Of Icts In Play Activities Of Irish Children (4-8 And 8-12), Brian O'Neill, Noirin Hayes, Stella Downey

Conference Papers

Defined in the Ireland’s national play policy as ‘freely chosen, personally directed, intrinsically motivated behaviour that actively engages the child’ (NCO, 2004, p.10), play now more often than not is a technologically-mediated activity. This paper focuses on the role of technology in play and explores the impact of technological change on children’s play activities. Drawing on our study commissioned by Ireland’s National Children’s Office, we present a detailed exploration of the play activities of Irish children, identifying the range of technologies accessed by children and how they are used in their daily play patterns. The project provided children with an …

Integrating Semantic Web Services For Mobile Access, Anupriya Ankolekar, Pascal Hitzler, Holger Lewen, Daniel Oberle, Rudi Studer

Computer Science and Engineering Faculty Publications

We present our work in integrating Semantic Web services for access via mobile devices. We have developed a system, the WebServiceAccessComponent, that transforms a user request for a service on a mobile device, to a Web service request and then selects a matching service from the existing Web services of the Deutsche Telekom, which provide navigational and weather information. In this poster, we present the requirements and design of the WebServiceAccessComponent.

Semantic Management Of Web Services Using The Core Ontology Of Services, Daniel Oberle, Steffen Lamparter, Andreas Eberhart, Stephan Grimm, Sudhir Agarwal, Rudi Studer, Pascal Hitzler

Kno.e.sis Publications

Different Web Service standards like WSDL, WS-Security, WS-Policy etc., henceforth referred to as WS*, factorize Web Service management tasks into different aspects, such as input/output, workflow, or security. The advantages of WS* are multiple and have already achieved industrial impact. WS* descriptions are exchangeable and developers may use different implementations for the same Web Service description. The disadvantages of WS*, however, are also apparent: even though the different standards are complementary, they must overlap and one may produce models composed of different WS* descriptions, which are inconsistent with each other, but the reasons for the inconsistencies are not easily determined. …

An Ontological Approach To The Document Access Problem Of Insider Threat, Boanerges Aleman-Meza, Phillip Burns, Matthew Eavenson, Devanand Palanswami, Amit P. Sheth

Kno.e.sis Publications

Verification of legitimate access of documents, which is one aspect of the umbrella of problems in the Insider Threat category, is a challenging problem. This paper describes the research and prototyping of a system that takes an ontological approach, and is primarily targeted for use by theintelligence community. Our approach utilizes the notion of semantic associations and their discovery among a collection of heterogeneous documents. We highlight our contributions in (graphically) capturing the scope of the investigation assignment of an intelligence analyst by referring to classes and relationships of an ontology; in computing a measure of the relevance …

Semantic Web Services For N-Glycosylation Process, Satya S. Sahoo, Amit P. Sheth, William S. York, John A. Miller

Kno.e.sis Publications

Glycomics is one of the many research efforts currently underway in the biosciences domain, which is characterized by high throughput data generated at multiple experimental stages. For example, analysis of N-glycosylation encompasses stages from cell-culture to peptide identification and quantification. Research groups across the world use diverse cell cultures, separation and spectroscopic techniques, and data identification, correlation and integration methodologies. Thus, data generated at different phases of the process by multiple groups are both structurally and functionally heterogeneous.
