Digital divide is one of the challenges that open government must face in mid- and low-income countries. In these contexts, inhabitants are left out of the benefits of information and communication technology (ICT), such as online government services. The present scenario that has emerged from the COVID-19 pandemic offers opportunities and challeng...

A finales del siglo XX y principios del XXI, la introducción de las tecnologías de información y comunicación (TIC) en el sector gubernamental ha producido una serie de cambios al interior de las administraciones públicas a nivel internacional. Las TIC han permitido transformar la manera tradicional en que se venían generando los servicios públicos...

This article addresses a problem in the electronic government discipline with special interest in Mexico: the need for a concentrated and updated information source about municipal e-government websites. One reason for this is the lack of a complete and updated database containing the electronic addresses (web domain names) of the municipal governm...

Resumen. Para hallar patrones significativos en grandes volúmenes de datos se ha usado inicialmente la estadística y, más recientemente, el aprendizaje automático, un área de la inteligencia artificial. La conjunción de estas disciplinas con la teoría y práctica de las bases de datos ha dado origen a la minería de datos, conocida también como descu...

La salud electrónica (e-salud o e-health) hace referencia a la aplicación de las tecnologías de información y comunicación (TIC) en el campo de la salud: desde la provisión de sistemas epidemiológicos hasta la prestación de servicios médicos en sus distintos niveles y especialidades, integrada por diversas aplicaciones, tales como las citas médicas...

Esta presentacion explica que son los datos abiertos de Mexico, como se usan y para que sirven.

Los datos abiertos gubernamentales disponibles actualmente (DENUE y SCIAN) ofrecen la oportunidad de crear un nuevo indice para describir y representar un fenomeno relevante en Mexico: perfiles de actividades economicas de los municipios.

Existe una necesidad de metodos y herramientas automaticas para encontrar, analizar y caracterizar los websites oficiales vigentes de gobierno electronico de los municipios de Mexico. Tomando como objeto de estudio al conjunto de todos estos websites, se necesita colectar y analizar: sus nombres de dominio, estatus operacional (funcionan o no), sec...

Se presenta una metodologia para modelar actos de dialogo en lenguaje hablado, con posibilidades de ser implementada en software para manejar la comunicacion humano-computadora o humano-robot.

This paper proposes to create a new paradigm on services for information search on the web, involving new protocols and standards. For more than one decade, the current paradigm has consisted in services that have been provided by a small number of private companies on an advertising business scheme, mainly. This concentration involves a number of...

This paper presents empirical results of an analysis on the role of prosody in the recognition of dialogue acts and utterance mood in a practical dialogue corpus in Mexican Spanish. The work is configured as a series of machine-learning experimental conditions in which models are created by using intonational and other data as predictors and dialog...

The present research analyzes the need for an area for management of information and communication technologies in the local government of a disadvantaged municipality in México. Also, the feasibility of its implementation is addressed and a pilot testing is proposed considering the social and economic constraints. Specifically, the characteristics...

This article proposes a methodology to model dialogue acts (DA) from part-of-speech (POS) annotations in practical dialogues in Mexican Spanish. An example using empirical data is presented to illustrate this methodology. DA and POS annotations were obtained from DIME, a spoken dialogue corpus in which speakers perform tasks in a virtual environmen...

In this paper a theory of dialogue structure of tas k oriented conversations and its associated tagging scheme are presented. The theory introduces two linguistic str uctures supporting the dialogue that, following tra ditional terminology, we call the obligations and common ground. The theory is illustrated with the detailed an alysis of a transac...

In this paper the automatic recognition of dialogue acts is evaluated on an empirical basis. Data from a dialogue corpus with spontaneous speech are used. In each dialogue two speakers collaborate to design a kitchen using a C.A.D. software tool; one of them plays the System's role and the other plays the User's role. Dialogue acts are annotated wi...

In this paper a methodology and preliminary results of a machine learning experiment for correlating intonation patterns and speaker information with dialogue acts are presented. The goal of this work is to assess the extent to which prosodic and speaker data can help to identify obligation dialogue acts within a specific practical-dialogues audio...

We describe an annotation scheme aimed at capturing continuous understanding be- havior in a multimodal dialogue corpus in- volving referential description tasks. By using multilayer annotation at the word level as opposed to sentence level, we can better understand the role of continuous understanding in dialogue. To this end, we annotate referrin...

In this paper a theory of dialogue acts analysis in problem-solving tasks-oriented conversations is presented. The theory postulates that in practical dialogues every transaction has a component in the obligations and the common ground planes of expression, and contributions made by dialogue acts making a “charge” in the transaction should be “bala...

In this paper, the influence of intonation to recognize dialogue acts from speech is assessed. Assessment is based on an empirical approach: manu- ally tagged data from a spoken-dialogue and video corpus are used in a CART- style machine learning algorithm to produce a predictive model. Our approach involves two general stages: the tagging task, an...

In this paper a theory of dialogue structure for task oriented conversations, and its associated tagging scheme is presented. The theory introduces two linguistic structures supporting the dialogue which are called the obligations and common ground. The analysis of a transaction of a corpus in task oriented conversations is also presented. The empi...

In this paper a methodology and prelimi-nary results of a machine learning ex-periment for correlating intonation patterns with dialogue acts are presented. The goal of this work is to assess the ex-tent to which prosodic information can help to identify dialogue act types.
