A Spatial Decision Support System for Tourism Land Use Planning
Get PDFOne of the most complex challenges the tourism industry faces is keeping up to date with information technology developments caused by the globalisation of information and advances in technology. The development of robust decision support systems for tourism land use planning is a way to address this challenge.This paper demonstrates how a spatial decision support system (SDSS), called the Land Use Decision sUpport System (LUDUS), can contribute in allocating complex forms of tourism. The system combines an artificial intelligence technique, called ontologies, with Geographic Information Systems and object-oriented programming to support decision-making in spatial planning. The system consists of two subsystems: the Insert Data Subsystem and the Graphic Imaging and Decision Support Subsystem. The core of the system is an ontology that is aligned to a standard of the Open Geospatial Consortium, called Geosparql.The case study of this paper is the Mastichochoria area of Chios Island, Greece. Therefore, the structure of the ontology was modelled according to the provisions of Greek legislation. The results produced confirmed the correct coding and application of the system’s criteria. The validity, accuracy and reliability of the results were also confirmed.The adopted approach facilitates the identification of alternative options for allocating, among other land use types, complex forms of tourism development in suburban areas, by examining the provisions of the legal framework as well as their geology and terrain
Spatial planning and information technology: an ontology-based approach
No full textProceedings of the IV World Planning Schools Congress, July 3-8th, 2016 : Global crisis, planning and challenges to spatial justice in the north and in the southOver the last three decades, the development of computer-based technologies has open unprecedented opportunities for knowledge building, design, evaluation and decision-making support in spatial planning. Spatial data technologies (e.g., geographic information systems, geographic positioning system) increased the availability of spatial information. Modern spatial planning approaches require integration, interpretation and representation of knowledge (Zhu et al., 1998). These needs can be addressed by computer-based systems, which are becoming an important tool for the decisionmaking process in spatial planning. Amongst the most popular research area of computer-based systems are the Spatial Decision Support Systems (SDSS). These systems aim to facilitate both experts and stakeholders throughout decision-making processes (Zhu et al., 1998) by taking into consideration varying parameters (e.g., institutional, urban, social, economical). However, traditional SDSS fall short of dealing with spatial problems that may be either semi-structured or may contain parameters that are difficult to be modeled due to uncertainties (Jankowski & Nyerges, 2001; Sikder, 2009).publishedVersio
Development of a spatial decision support system for land-use suitability assessment: The case of complex tourism accommodation in Greece
No full textLand-use suitability assessment necessitates the analysis of multiple parameters as well as the compliance with the legal framework, the priorities, and the beliefs of all stakeholders involved in forming and implementing spatial policies. The approach followed in this paper is based on combining Ontologies, GIS and Object-oriented programming, to develop a SDSS capable of supporting decision-making in land-use planning. The applicability of the system is demonstrated using the case-study of a Greek island. The proposed approach promotes the integration of modern technologies into the processes of spatial planning and enhances the strong trend towards using the benefits of knowledge-management in decision-making

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Monitoring the Response of connected moored floating modules
No full textIn the present paper a recently installed Sensor Network for Monitoring the Response (SNMR) of a Floating Structure (FS) is presented. SNMR is deployed on a pontoon-type FS operating as a floating breakwater, located 300m from the coast in the port of Neos Marmaras in Greece. The developed SNMR consists of: (i) sensors for real time measurement of FS's critical response quantities related with the structural integrity and safety of the FS as well as of environmental parameters and (ii) data acquisition and data transfer and storage system. Characteristic examples of time series of the measure quantities obtained during the operation of the SNMR are presented and preliminary assessed.
