Morphisms In Context, Markus Krotzsch, Guo-Qiang Zhang, Pascal Hitzler Jul 2005

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 Modular Approach To Document Indexing And Semantic Search, Dhanya Ravishankar, Krishnaprasad Thirunarayan, Trivikram Immaneni Jul 2005

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 …

Computational Optical Biopsy, Yi Li, Ming Jiang, Ge Wang Jun 2005

Computational Optical Biopsy, Yi Li, Ming Jiang, Ge Wang

Mathematics and Statistics Faculty Publications

Optical molecular imaging is based on fluorescence or bioluminescence, and hindered by photon scattering in the tissue, especially in patient studies. Here we propose a computational optical biopsy (COB) approach to localize and quantify a light source deep inside a subject. In contrast to existing optical biopsy techniques, our scheme is to collect optical signals directly from a region of interest along one or multiple biopsy paths in a subject, and then compute features of an underlying light source distribution. In this paper, we formulate this inverse problem in the framework of diffusion approximation, demonstrate the solution uniqueness properties in …

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 Jun 2005

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 Jun 2005

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 …

Towards A Systematic Account Of Different Semantics For Logic Programs, Pascal Hitzler Jun 2005

Towards A Systematic Account Of Different Semantics For Logic Programs, Pascal Hitzler

Computer Science and Engineering Faculty Publications

A new methodology has been proposed which allows one to derive uniform characterizations of different declarative semantics for logic programs with negation. One result from this work is that the well-founded semantics can formally be understood as a stratified version of the Fitting (or Kripke–Kleene) semantics. The constructions leading to this result, however, show a certain asymmetry which is not readily understood. We study this situation here with the result that we obtain a coherent picture of relations between different semantics for normal logic programs.

Role Of Near-Surface States In Ohmic-Schottky Conversion Of Au Contacts To Zno, H. L. Mosbacker, Y. M. Strzhemechny, B. D. White, P. E. Smith, David C. Look, D. C. Reynolds, C. W. Litton, L. J. Brillson Jun 2005

Role Of Near-Surface States In Ohmic-Schottky Conversion Of Au Contacts To Zno, H. L. Mosbacker, Y. M. Strzhemechny, B. D. White, P. E. Smith, David C. Look, D. C. Reynolds, C. W. Litton, L. J. Brillson

Physics Faculty Publications

A conversion from ohmic to rectifying behavior is observed for Au contacts on atomically ordered polar ZnO surfaces following remote, room-temperature oxygen plasma treatment. This transition is accompanied by reduction of the “green” deep level cathodoluminescence emission, suppression of the hydrogen donor-bound exciton photoluminescence and a ∼ 0.75 eV increase in n-type band bending observed via x-ray photoemission. These results demonstrate that the contact type conversion involves more than one mechanism, specifically, removal of the adsorbate-induced accumulation layer plus lowered tunneling due to reduction of near-surface donor density and defect-assisted hopping transport.

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 Jun 2005

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. …
