Item Introduction of non-topological costs in syntactic analyses : the case of Gulbenkian estate(2022) Fernandes, Pedro AfonsoSpace syntax is a set of theories and techniques for analysing urban settlements and buildings. Focused on the study of the configuration of convex spaces, space syntax is based on the concept of topological depth, that is, in the number of steps to go from some space (or axial line) to every other space in a spatial complex. Typically, non-topological costs like stairs, ramps, accentuated slopes or walls are not considered in space syntax analyses, or are incorporated in an insufficient fashion, namely, with the arbitrary introduction of axial lines in order to increase depth. This article proposes an innovative method to deal with these costs that uses logic programming with Prolog language. In this way, it is possible to better understand the relative segregation of the Gulbenkian estate within its urban environment, the city of Odivelas near Lisbon (Portugal), noting that it was the largest public housing estate built within the scope of the resettlement plan for those displaced by the great floods of November 25-26, 1967, established by the Ministry of Public Works and the Calouste Gulbenkian Foundation in the late 1960s.

It is a relevant approach for spatial studies concerned with the scientific understanding of and intervention in public open spaces. It requires a previous convex/line/segment map of the area in question designed with the aid of CAD or GIS. Such preparatory task may be laborious and more difficult for social researchers than for architects or urban planners. A new approach to syntactic analyses is proposed here; it requires only setting the connections between axial lines or convex spaces in a computer program. We performed a settlement (alpha) analysis of the Areeiro neighbourhood in Lisbon by computing connectivity, control, depth, integration, ringiness and other syntactic measures, using Prolog predicates. Prolog is a logic programming language used in Artificial Intelligence and a powerful tool to describe the patterns of urban systems as socially knowable due to its declarative nature. In fact, a Prolog program represents a certain amount of knowledge, in this case, of an urban settlement such Areeiro, which is used to answer queries about the social and economic consequences of the spatial design. This approach revealed the intelligibility but also the weaknesses of Areeiro, a remarkable milestone for Portuguese urbanism from the mid-20th century.

The authors of this chapter represent widely diverse disciplines, including environmental engineering, economics, urban planning and design, landscape architecture and education. The chapter intends to deliver a tailored and timely vision of how, with the help of Citizen Science, the democratisation of science can be promoted and, with this, more collective and sustainable decision making achieved. This chapter is the result of a reflective dialogue between researchers, their projects and experiences tackling spatial and human development from different perspectives. It gathers the conclusions that emerged in the organised debates and the research projects carried out by the researchers, towards creating a broad understanding of the key issues that could help operationalise Citizen Science in future research efforts. Keywords – Citizen science, socio-spatial research, key principles of citizen science, citizen's contribution to science, social sciences.
