Natural Language Processing Agents and Document Clustering in Knowledge Management

2008

While HTML provides the Web with a standard format for information presentation, XML has been made a standard for information structuring on the Web. The mission of the Semantic Web now is to provide meaning to the Web. Apart from building on the existing Web technologies, we need other tools from other areas of science to do that. This chapter shows how natural language processing methods and technologies, together with ontologies and a neural algorithm, can be used to help in the task of adding meaning to the Web, thus making the Web a better platform for knowledge management in general.

La formación profesional en la construcción de trayectorias laborales. Estudio sobre sectores productivos en Argentina

2021

El artículo se ubica en el campo problemático entre educación y trabajo buscando caracterizar de manera específica la formación profesional —FP—. Para ello interesa analizar el lugar que ocupa este tipo de formación en las trayectorias laborales de los trabajadores. El texto parte de un estudio cualitativo —101 entrevistas entre directivos, profesores y alumnos— realizado en cuatro familias profesionales con alta demanda de formación en Argentina: electricidad, construcción, agroindustria y mecánica automotor. Se propone una mirada que permita recuperar el lugar que la FP ha tenido en diversas fases de los modelos de desarrollo económico colocando el énfasis sobre la formación profesional d…

Identifying motives underlying wine purchase decisions: Results from an exploratory free listing task with Burgundy wine consumers

2014

Abstract To better understand consumer decision making processes while purchasing wine it is important to identify which attributes consumers actually rely on and how they perceive and weight them in order to reach a final decision. The aims of the present work were to identify motives underlying wine purchase decisions and to identify consumer segments with different drivers of wine purchase. One hundred and twenty seven Burgundy wine consumers were asked to complete a free listing task. Relevance of each category of elicited terms was estimated by Smith's and Cognitive saliency indices. Hierarchical cluster analysis was performed on individual Smith's saliency indices. In the free listing…

Internet Disclosure by Nonprofit Organizations: Empirical Evidence of Nongovernmental Organizations for Development in Spain

2009

This article examines the relevance of technology, and particularly the Internet, for the improvement of accountability and transparency in nonprofit organizations. The novelty of our work regarding the previous empirical evidence resides in the fact that we have taken into account the means through which these organizations diffuse voluntary information. In this article, we have proposed a model of information disclosure for the Web sites of Spanish nongovernmental organizations for development (NGODs) that can serve as a guide for improving their informative transparency and their accountability. The empirical evidence obtained reveals that Spanish NGOD Web sites are primarily ornamental…

The Hints from the Crowd Project

2013

Can the crowd be a source of information? Is it possible to receive useful hints from comments, blogs and product reviews? In the era of Web 2.0, people are allowed to give their opinion about everything such as movies, hotels, etc.. These reviews are social knowledge, that can be exploited to suggest possibly interesting items to other people. The goal of the Hints From the Crowd HFC project is to build a NoSQL database system for large collections of product reviews; the database is queried by expressing a natural language sentence; the result is a list of products ranked based on the relevance of reviews w.r.t. the natural language sentence. The best ranked products in the result list ca…

Reports and other PDF Documents

2014

Stata users often need to combine text, tables, and figures. The author's command, lpdf, generates reports and other PDF documents. lpdf compiles text stored in global macros, tables stored as dataset tables or LATEX table input files, and figures stored as Stata graphs or PDF figure files. LATEX must be installed, but familiarity with LATEX is not necessary. lpdf performs every step through Stata and with Stata syntax. It generates documents in report or article style and portrait or landscape orientation. The default author name, document title, and date can be modified. Further format options include the font and margin sizes. For each table and figure, the width and layout can be adapt…

Towards Introducing User Preferences in OLAP Reporting Tool

2012

This paper presents an OLAP reporting tool and an approach for determining and processing user OLAP preferences, which are useful for generating recommendations on potentially interesting reports. We discuss the metadata layers of the reporting tool including our proposed OLAP preferences metamodel, which supports various scenarios of formulating preferences of two different types: schema-specific and report-specific. The process of semantic metadata usage at the stage of formulating user preferences is also considered. The methods for processing schema-specific and report-specific OLAP preferences are outlined.

Context-aware summary generation for Web pages

2009

General purpose search engines provide users with lists of retrieved documents in response to their queries. The common structure of list elements includes the title of a document, its URL, and small snippet from the text. Snippets are evidence of occurrences of query's keywords in the document. The length of each snippet is just a couple of lines. They cannot play a role of summaries of retrieved documents: In many cases, they are not indicative and users cannot judge on the relevancy of documents. In our approach we use ontology as context description and that ontology will be used to describe user's main interest with respect to wanted summary and help to select weighting of key words an…

Interpreting Heterogeneous Geospatial Data Using Semantic Web Technologies

2016

International audience; The paper presents work on implementation of semantic technologies within a geospatial environment to provide a common base for further semantic interpretation. The work adds on the current works in similar areas where priorities are more on spatial data integration. We assert that having a common unified semantic view on heterogeneous datasets provides a dimension that allows us to extend beyond conventional concepts of searchability, reusability, composability and interoperability of digital geospatial data. It provides contextual understanding on geodata that will enhance effective interpretations through possible reasoning capabilities. We highlight this through …
