Periodic Reporting for period 1 - ArchBiMod (Agent-Based Modelling to assess the quality and bias of the archaeological record)
Période du rapport: 2021-09-01 au 2023-08-31
This can transfer to society in several ways. First, it constitutes a meta-scientific project which not archaeology, but every discipline where biases and problems on the data are important, can benefit from. This virtually includes several research disciplines studying the past (e.g. Paleontology) but also current disciplines where the recovery of data is an additional challenge. Additionally, and by properly assessing how these data are affecting our current knowledge of the past, the project has been able to refine certain theoretical aspects affecting the life and interactions of the last-hunter gatherers and the first farmers of the Western Mediterranean, while also extending its methods and inferential background to other global areas (e. g. Scandinavia or Japan).
The overall objectives of the project were, first, determining the most relevant biases affecting archaeological research. The project has been successful in this regard by developing large amount of computational simulation, and the consequences of the different biases considered, modelling from the moment in which the record is produced to how this is lost and how archaeologists condition our potential hypothesis building through their different methodological approaches. Second, the project was interested in understanding how tactical simulation could help us in this regard. The extensive deployment of this technique has allowed the project not only to obtain a better informed knowledge of how different parameters interact and condition our theoretical framework, but it has also given place to some enhanced methodological solutions that can be exported to different scientific fields.
Finally, the project has been able to reassess and challenge (as will be shown in upcoming publications) some currently standing theories, regarding the spread of farming, that were relying on under-assessed data. By focusing on the process that define the archaeological data and the methods that we used to extract the most information out of it, the project has been able to bring further archaeological hypothesis building as well as developed bespoke methodologies that can be exported and used in different research problems.
The project has achieved satisfactory results. It has been successful in raising a strong awareness on how biases in archaeological data condition our current hypothesis building framework, and it has done so through the participation on several international conferences and publications (see below). In this regard, the project has made use of some of the most advanced statistical techniques (e. g. simulation, Bayesian computation) as well as introducing techniques not yet spread within the archaeological main methodological toolkit (e. g. t-SNE). Additionally, in the publications in their final stages of preparation, the project will introduce developments spread within the ecological modelling framework, but not within archaeology (e. g. dynamic models) as well as publish bespoke solutions aimed to be future research tools for the wider archaeological community (e. g. modelling of record loss and disturbance on archaeological sites through interactive ShinyApp websites). All this provides a good quality of the results, positioning the project at the vanguard of archaeological methodological development, while contributing to raising awareness of archaeological data deficiencies.
All these has been translated in the attendance to several scientific conferences in different places such as Kiel, Amsterdam, Budapest or Belfast and 8 dedicated publications (plus two currently under review), all of which are mentioned in the technical report. Finally, the final results should include at least three more publications, which capture in detail the advancements produced by the project, all of which are on their final stages, and should be sent out for review between the next days and the end of the present year.
With the work already done, the project has brought methodological reception, and also creative ways to face the challenges posed by the archaeological record through reproducible and quantitative methodologies. Additionally, with the culmination of the final publications, still under production, and which should be sent for review shortly the project will finally close its circle and present how this new focus on the record itself can ultimately lead us to a further insight into potential past processes.
