In the actual context of growing interests in environmental issues, reducing energy consumption in the transport sector, which represents 27% of final energy in the Walloon region of Belgium, appears as an important policy target. Although it is often argued that more compact urban forms would significantly reduce transport energy consumption, urban sprawl is a concern in a large part of the regional territory. Moreover, assessment tools dedicated to transport energy consumption are lacking. In this context, the paper first presents a quantitative method developed to assess the transport system in the Walloon region of Belgium. Statistical data available at the neighbourhood scale and characteristics of cars and public vehicles are used to predict transport needs and assess energy consumption as far as home-to-work and home-to-school travels are concerned. Three index are presented and mapped (the energy performance index, the modal share and the mean distance travelled) to investigate the interdependences between spatial planning, urban sprawl and travel energy consumption in the Walloon region of Belgium. Three complementary scales are used: the “municipality” scale allows to highlight the general structure of the territory whereas the “former municipality” and the “census block” scales (the smallest geographical unit in which data are available in Belgium) highlight more detailed phenomenon. The evolution of the performance index between 1991 and 2001 and the difference in energy performance between home-to-work and home-to-school travels are also presented. Our main findings are presented and highlight that urban planning acts upon travel energy consumption. We show particularly that main cities present low energy consumption. However, a local scale approach is useful to highlight the existence of secondary suburban and rural cores presenting low transport energy consumption. In this respect, distance from home to destination is paramount while the mode of transport used has a lower impact. [less ▲]

A growing need for objective assessment of colour has been observed in recent years in the field of urban design. In contrast to other building attributes (shape, size or location), which are easy to specify, urban design codes generally define expected chromatic attributes of building façades through indirect regulations considering materials. Some municipalities propose colour charts as guidance tools for urban regulation which present some disadvantages. This obvious lack of affordable instruments in a purpose of characterization or regulation was the main motivation of this research. The aim of this paper is to present a user-oriented protocol which can be applied to characterize chromatic attributes of an urban fragment. The challenge is to provide quantitative answers to these two questions: how is colour organized, how does it develop a structure in the city? The main purpose of the research is hence to investigate stable colour typologies within the city; each urban area (historic center, suburban housing district, commercial zone, etc.) being characterized by a specific colour palette.

In the information retrieval context, resource collections are frequently classified using thesauri. However, the limited semantics pro- vided by thesauri restricts the collection search and browsing capabilities. This work focuses on improving these capabilities by transforming a set of resources indexed according to a thesaurus into a semantically tagged collection. The core mechanism for building this collection is based on the conversion of the domain specific thesaurus (indexing the collection of resources) into a domain ontology connected to an upper level ontol- ogy. The feasibility of this work has been tested in the urban domain by transforming the resources accessible through the European Urban Knowledge Network into a Linked Data repository. [less ▲]

Since the development of ontologies from scratch requires much time and many resources, the activity of knowledge acquisition constitutes one of the most impor- tant steps at the beginning of the ontology development process. This activity is essential in all the different methodologies for ontology design as a previous step to the conceptualization and formalization phases. And as its name indicates, this activity is devoted to gather all available knowledge resources describing the domain of the ontology and identify the most important terms in the domain. This chapter is focused on the study of methods and techniques for the (semi-) automatic processing of knowledge resources that may alleviate the work of knowledge acquisition. This task is known as ontology learning in the literature of ontological engineering. The aim of ontology learning is to apply the most appropriate methods to transform unstructured (e.g., text corpora), semi-structured (e.g., folksonomies, HTML pages) and structured data sources (e.g., databases, thesauri) into conceptual structures. The methods of ontology learning are usually connected with the activity of ontology population, which also relies on (semi-)automatic methods to transform unstruc- tured, semi-structured and structured data sources into instance data (i.e., instances of ontology concepts).

Nous présentons ici une recherche relative à l’impact de la structuration du territoire sur les émissions de gaz à effets de serre (GES). Trois champs de variables ont été prospectés à cette fin : les variables territoriales bien sûr, mais également socio-économiques et technologiques, Celles-ci ont permis l’élaboration d’un cadastre énergétique des émissions dans deux domaines principaux de l’aménagement du territoire: la mobilité et le bâti. Il ressort de ces analyses que des gains d’émissions de GES appréciables sont envisageables à court à et à long terme, notamment dans le domaine du bâti. Cependant, ils ne peuvent être interprétés sans une réflexion de nature territoriale. La Wallonie est de fait caractérisée par une forte périurbanisation combinée à un très faible recyclage du parc bâti. Ces caractéristiques structurelles du territoire imposent aujourd’hui de formuler des réponses adaptées à différents types d’urbanisation (urbain, rural, périurbain). [less ▲]

Dans le cadre du programme de mise en œuvre 2008-2009 de la CPDT (Conférence Permanente du Développement Territorial), des chercheurs du Lepur (Centre de Recherche en Sciences de la Ville, du Territoire et du Milieu rural) ont réalisé une analyse des 283 projets Interreg III (période de programmation 2000-2006) impliquant un ou plusieurs partenaires wallons dans le but de mettre en évidence leurs dimensions territoriale et urbaine. Pour mener à bien cette analyse, un questionnaire d’enquête a été envoyé à 356 contacts officiels wallons. Les principaux résultats obtenus doivent être interprétés avec une certaine réserve puisqu'ils reposent uniquement sur les déclarations des partenaires wallons interrogés. [less ▲]

Cette note de recherche se penche sur un nouvel outil wallon en faveur de la redynamisation des villes, le remembrement urbain. Cet outil qui trouve son origine dans la Déclaration de la Politique régionale 2004-2009, n’a été appliqué jusqu’à présent que dans cinq dossiers. L’approche prospective adoptée dans cette note de recherche se base sur ces cinq expériences et sur une série d’entretiens avec les acteurs-clés du remembrement urbain. Après une analyse historique et juridique de l’outil, la note aborde le RU sous un angle plus opérationnel. En conclusion, les auteurs établissent une série de recommandations dressent quelques perspectives de développement. [less ▲]

Ontology learning is the term used to encompass methods and techniques employed for the (semi-) automatic processing of knowledge resources that facilitate the acquisition of knowledge during ontology construction. This chapter focuses on ontology learning techniques using thesauri as input sources. Thesauri are one of the most promising sources for the creation of domain ontologies thanks to the richness of term definitions, the existence of a priori relationships between terms, and the consensus provided by their extensive use in the library context. Apart from reviewing the state of the art, this chapter shows how ontology learning techniques can be applied in the urban domain for the development of domain ontologies. [less ▲]

Thesauri are used for document referencing. They define hierarchies of domains. We show how document and domain contents can be used to validate and update a classification based on a thesaurus. We use document indexing and classification techniques to automate these operations. We also draft a methodology to systematically address those issues. Our techniques are applied to Urbamet, a thesaurus in the field of town planning. [less ▲]
