Yet, combining new and existing results is hampered by inconsistent standards in the recording and illustration of archaeological features and artefacts. Attempts at collating data from images in existing publications first involve scouring the substantial body of existing literature, followed by extracting images that require onerous manual preprocessing steps, like re-scaling, re-orienting, and re-formatting. While the sample sizes of such manual analyses are curtailed by these problems, recent developments in AI and big data methods are poised to accelerate and automate large syntheses of existing data. This paper introduces an AI-assisted workflow capable of creating uniform archaeological datasets from heterogeneous published resources. The associated software (AutArch) takes large and unsorted PDF files as input, and uses neural networks to conduct image processing, object detection, and classification. Objects commonly found in archaeological catalogues – like graves, skeletons, ceramics, ornaments, stone tools, and maps – are reliably detected. Accompanying elements of the illustrations, like North arrows and scales, are automatically used for orientation and scaling. Outlines are then extracted with contour detection, allowing whole-outline morphometrics. Detected objects, contours, and other automatically retrieved data can be manually validated and adjusted via AutArch’s graphical user interface. While we test this workflow on third millennium BCE Central European graves and Final Neolithic/Early Bronze Age arrowheads from Northwest Europe, this method can be applied to the vast number of artefacts and archaeological features for which shape, size, and orientation holds technological, functional, cultural, and/or temporal significance. This AI-assisted workflow has the potential to speed-up, automate, and standardise data collection throughout the discipline, allowing more objective interpretations and freeing sample sizes from budget and time constraints.» weiterlesen» einklappen
