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

Kno.e.sis Publications

The current WSDL standard operates at the syntactic level and lacks the semantic expressivity needed to represent the requirements and capabilities of Web Services. Semantics can improve software reuse and discovery, significantly facilitate composition of Web services and enable integrating legacy applications as part of business process integration. The Web Service Semantic s technical note defines a mechanism to associate semantic annotations with Web services that are described using Web Service Description Language (WSDL). It is conceptually based on, but a significant refinement in details of, the original WSDL-S proposal [WSDL-S] from the LSDIS laboratory at the University of Georgia. …

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.

Divide-And-Approximate: A Novel Constraint Push Strategy For Iceberg Cube Mining, Ke Wang, Yuelong Jiang, Jeffrey Xu Yu, Guozhu Dong, Jiawei Han

Kno.e.sis Publications

The iceberg cube mining computes all cells v, corresponding to GROUP BY partitions, that satisfy a given constraint on aggregated behaviors of the tuples in a GROUP BY partition. The number of cells often is so large that the result cannot be realistically searched without pushing the constraint into the search. Previous works have pushed antimonotone and monotone constraints. However, many useful constraints are neither antimonotone nor monotone. We consider a general class of aggregate constraints of the form f(v)θ_σ, where f is an arithmetic function of SQL-like aggregates and θ is one of <, ≤, ≥, > . We propose a …

Gamers’ Sensations Of Spatial, Social, And Co-Presence While Playing Online Video Games, Cheryl Campanella Bracken, R. L. Lange, James Denny

Communication Faculty Publications

There is an increasing number of video gamers who are playing games online. Previous research has demonstrated that off line gamers experience sensations of presence “the illusion of non-mediation” (Lombard & Ditton, 1997). The current study, explores through focus groups, the type of presence online gamers report experiencing. The results demonstrate that online gamers report having sensations that can be classified into all three main presence types: spatial (physical), social, and co-presence.

Necklaces Used In The Santería Of Cuba, Lourdes S. Domínguez

BEADS: Journal of the Society of Bead Researchers

This article examines the necklaces used in the Afro-Cuban Rule of Orisha, more commonly known as Santería. This religion, created by African slaves brought to Cuba starting in the 16th century, combines aspects of Yoruba orisha worship and Spanish Catholicism. It allowed African religious beliefs and practices to survive despite the imposition of Catholic doctrine. One of the outcomes of this amalgamation is the practice of associating individual orishas (deities) with certain Catholic saints. Each orisha is represented by specific necklaces that incorporate particular bead forms, colors, and numbers.

Elemental Analyses Of North American Glass Trade Beads, R. G.V. Hancock

BEADS: Journal of the Society of Bead Researchers

Although European-made glass trade beads can be sorted into bead varieties and studied in that manner on the basis of physical attributes, much more information can be obtained about them by means of chemical analysis. Such analyses produce chemical fingerprints that may be compared and grouped. Bead varieties that have matching chemistries were made using the same ingredients that probably came from the same sources, suggesting that they were made in a specific manufacturing center and probably during the same approximate time period. Using this information may help to establish with which European nationals specific indigenous people were dealing and …

A Random Rotation Perturbation Approach To Privacy Preserving Data Classification, Keke Chen, Ling Liu

Kno.e.sis Publications

This paper presents a random rotation perturbation approach for privacy preserving data classification. Concretely, we identify the importance of classification-specific information with respect to the loss of information factor, and present a random rotation perturbation framework for privacy preserving data classification. Our approach has two unique characteristics. First, we identify that many classification models utilize the geometric properties of datasets, which can be preserved by geometric rotation. We prove that the three types of classifiers will deliver the same performance over the rotation perturbed dataset as over the original dataset. Second, we propose a multi-column privacy model to address the …

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 …

Wsdl-S: Adding Semantics To Wsdl, John Miller, Kunal Verma, Preeda Rajasekaran, Amit P. Sheth, Rohit Aggarwal, Kaarthik Sivashanmugam

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 …

Level Mapping Characterizations Of Selector-Generated Models For Logic Programs, Sibylle Schwarz, Pascal Hitzler

Computer Science and Engineering Faculty Publications

Assigning semantics to logic programs via selector generated models (Schwarz 2002/2003) extends several semantics, like the stable, the inflationary, and the stable generated semantics, to programs with arbitrary formulae in rule heads and bodies. We study this approach by means of a unifying framework for characterizing different logic programming semantics using level mappings (Hitzler and Wendt 200x, Hitzler 2003), thereby supporting the claim that this framework is very flexible and applicable to very diversely defined semantics.

Thirteen-Hundred-Year-Old Bead Adornments From Baar, Canton Zug, Switzerland, Katharina Müller

BEADS: Journal of the Society of Bead Researchers

In the year 2000, an Early Medieval (7th-century) cemetery containing more than 200 burials with rich grave goods was discovered in Baar, Canton Zug, Switzerland. Thanks to the painstaking methods used in the excavation and recording of the 2,985 glass, amber, coral, and amethyst beads found with the female burials, it was possible to reconstruct the necklaces and sewn-on appliqués they were part of. Comparisons with mosaic depictions of famous women—such as the Empress Theodora in San Vitale in Ravenna, Italy—suggest that the people of Baar imitated southern Alpine Byzantine bead jewelry fashion.

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.

Ranking Complex Relationships On The Semantic Web, Boanerges Aleman-Meza, Christian Halaschek-Wiener, I. Budak Arpinar, Cartic Ramakrishnan, Amit P. Sheth

Kno.e.sis Publications

Industry and academia are both focusing their attention on information retrieval over semantic metadata extracted from the Web, and it is increasingly possible to analyze such metadata to discover interesting relationships. However, just as document ranking is a critical component in today's search engines, the ranking of complex relationships would be an important component in tomorrow's semantic Web engines. This article presents a flexible ranking approach to identify interesting and relevant relationships in the semantic Web. The authors demonstrate the scheme's effectiveness through an empirical evaluation over a real-world data set.

Variational Bayesian Image Modelling, Li Chen, Feng Jiao, Dale Schuurmans, Shaojun Wang

Kno.e.sis Publications

We present a variational Bayesian framework for performing inference, density estimation and model selection in a special class of graphical models—Hidden Markov Random Fields (HMRFs). HMRFs are particularly well suited to image modelling and in this paper, we apply them to the problem of image segmentation. Unfortunately, HMRFs are notoriously hard to train and use because the exact inference problems they create are intractable. Our main contribution is to introduce an efficient variational approach for performing approximate inference of the Bayesian formulation of HMRFs, which we can then apply to the density estimation and model selection problems that arise when …

Framework For Semantic Web Process Composition, Kaarthik Sivashanmugam, John A. Miller, Amit P. Sheth, Kunal Verma

Kno.e.sis Publications

Web services have the potential to revolutionize e-commerce by enabling businesses to interact with each other on the fly. To date, however, Web processes using Web services have been created mostly at the syntactic level. Current composition standards focus on building processes based on the interface description of the participating services. This rigid approach, with its strong coupling between the process and the interface of the participating services, does not allow businesses to dynamically change partners and services. As shown in this article, Web process composition techniques can be enhanced by using semantic process templates to capture the semantic requirements …

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 …

Late 19th- And Early 20th-Century Manufacture Of Drawn Glass Tubing For Glass Beads, Lester A. Ross

BEADS: Journal of the Society of Bead Researchers

Late 19th- and early 20th-century archaeological sites often contain machine-made drawn glass beads with unique shapes and perforations. Little information exists documenting when these beads were initially manufactured. Through an examination of hundreds of U.S. patents, it appears that the mechanized production of drawn beads could have occurred as early as the late 19th-century, but more likely, they were not mass produced until the end of World War I, after the invention of the Danner process for mechanically drawing glass tubing. Machine-made drawn beads with multiple sides and/or shaped perforations also appear to have been produced by the late-19th century, …

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 …

Inventory Management Improvement Techniques, James Lanman

Masters Theses

An inventory management system that does not ensure inventory record accuracy greatly reduces the ability of a company to control inventory levels and fulfill customer requirements. This study investigated how two principles of inventory management affected three business metrics: on-time delivery, inventory record accuracy, and inventory level management.

Eight manufacturers of aircraft parts and equipment in northeastern lllinois responded to a survey created to analyze the effects of ABC classification of inventory and cycle counting techniques on inventory management. Survey data were collected via teleconference with a representative of each manufacturer.

Half of the manufacturers reported using ABC inventory classification …

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, …
