Aplicación de las wikis semánticas como herramienta de gestión del conocimiento operativo en un departamento de TICs

En este proyecto se ha tratado de estudiar la viabilidad de las wikis semánticas para el registro informal (pero consultable) de información operativa de un departamento de una empresa.

Uso de wikis semánticas

En el presente PFC vamos a estudiar a fondo las wikis semánticas, para tratar de plasmar primeramente el estado del arte de éstas, su aprovechamiento y uso real, más allá de su concepción teórica o prototípica. Posteriormente utilizaremos una de ellas para realizar un ejercicio práctico, cargando una ontología nueva desarrollada para ésta y probando la potencia de las consultas sobre ésta.

Herramientas de wikis semánticos

Este trabajo pretende hacer un análisis sobre la web semántica, centrándose en los wikis semánticos, definiendo qué son, cómo trabajan, estableciendo las situaciones en las que son necesarios..., y concluyendo con un estado del arte de las herramientas que se nos ofrecen y analizando una de ellas.

WOW: wiki aided organization draWing

As the world evolves, organizations are becoming more and more complex, and the need to understand that complexity is increasing as well. With this demand, arises organizational engineering, which is a subject that emerged with the purpose to make organizations easier to understand, by putting in practice the concept of organizational self-awareness, which means that that the collaborators who are part of an organization, need to understand it and know what their role in it is. The DEMO methodology (Design Engineering Methodology for Organizations), came up with the purpose of representing these organizations’ self-awareness, through the definition and creation of consistent and coherent diagrams. Semantic wikis have features that can help in enterprise modelling. UEAOM (Universal Enterprise Adaptive Organization Model) is a model that allows the specification and dynamic evolution of languages, meta-models, models, and their representations as diagrams and tables. In this project, it was implemented a system based on UEAOM, and Semantic Media Wiki which allows a graphical creation and edition of diagrams. UEAOM can be divided into the meta-modeling level where a language is defined, and the modelling level where instances of classes of that language are created. The system we developed focuses on the modeling level, but will takes as a basis the project that focuses on meta-modeling. The DEMO language was used as an example for the implementation and tests of a graphical editor, based in web technologies and SVG, integrated with SemanticMediaWiki to allow an intuitive, coherent and consistent navigation and editing of organization diagrams.

Wikis semàntiques : Què són? Com són? Com treballen? Quan calen?

En aquest treball s'analitza el funcionament de Semantic MediaWiki, que es basa en MediaWiki, una wiki tradicional mundialment coneguda per ser la base amb què es va desenvolupar Wikipedia. Abans s'identifiquen les principals tecnologies de la web semàntica i es defineix el propòsit de les wikis semàntiques.

Uso de wikis semánticas

En este trabajo se ha realizado una tarea de investigación con la finalidad de construir una ontología para cargarla en una wiki semántica y así analizar su funcionamiento.

Uso de wikis semánticas

Este es el producto obtenido del proyecto final de carrera sobre el uso de wikis semánticas en el que se describen lo que son ontologías, sus lenguajes, las wikis semánticas y un caso práctico.

The Use of Latent Semantic Indexing to Mitigate OCR Effects of Related Document Images

Due to both the widespread and multipurpose use of document images and the current availability of a high number of document images repositories, robust information retrieval mechanisms and systems have been increasingly demanded. This paper presents an approach to support the automatic generation of relationships among document images by exploiting Latent Semantic Indexing (LSI) and Optical Character Recognition (OCR). We developed the LinkDI (Linking of Document Images) service, which extracts and indexes document images content, computes its latent semantics, and defines relationships among images as hyperlinks. LinkDI was experimented with document images repositories, and its performance was evaluated by comparing the quality of the relationships created among textual documents as well as among their respective document images. Considering those same document images, we ran further experiments in order to compare the performance of LinkDI when it exploits or not the LSI technique. Experimental results showed that LSI can mitigate the effects of usual OCR misrecognition, which reinforces the feasibility of LinkDI relating OCR output with high degradation.

A Procedure for Semantic Querying in the Adaptive Formalism

This paper contains a new proposal for the definition of the fundamental operation of query under the Adaptive Formalism, one capable of locating functional nuclei from descriptions of their semantics. To demonstrate the method`s applicability, an implementation of the query procedure constrained to a specific class of devices is shown, and its asymptotic computational complexity is discussed.

Semantic molecules

This paper explains and explores the concept of "semantic molecules" in the NSM methodology of semantic analysis. A semantic molecule is a complex lexical meaning which functions as an intermediate unit in the structure of other, more complex concepts. The paper undertakes an overview of different kinds of semantic molecule, showing how they enter into more complex meanings and how they themselves can be explicated. It shows that four levels of "nesting" of molecules within molecules are attested, and it argues that while some molecules such as 'hands' and 'make', may well be language-universal, many others are language-specific.
