The paper entitled 'Social Network Analysis, Community Detection Algorithms, and Neighbourhood Identification in Pompeii' [1] presents a significant contribution to the field of archaeological network research, particularly in the challenging task of identifying urban neighborhoods within the context of Pompeii. This study focuses on the relational dynamics within urban neighborhoods and examines their indistinct boundaries through advanced analytical methods. The methodology employed provides a comprehensive analysis of community detection, including the Louvain and Leiden algorithms, and introduces a novel Convex Hull of Admissible Modularity Partitions (CHAMP) algorithm. The incorporation of a network approach into this domain is both innovative and timely.

The potential impact of this research is substantial, offering new perspectives and analytical tools. This opens new avenues for understanding social structures in ancient urban settings, which can be applied to other archaeological contexts beyond Pompeii. Moreover, the manuscript is not only methodologically solid but also well-written and structured, making complex concepts accessible to a broad audience.

In conclusion, this study represents a valuable contribution to the field of archaeology, particularly for archaeological network research. Their results not only enhance our knowledge of Pompeii but also provide a robust framework for future studies in similar historical contexts. Therefore, this publication advances our understanding of social dynamics in historical urban environments. The rigorous analysis, combined with the innovative application of network algorithms, makes this study a noteworthy addition to the existing body of network science literature. It is recommended for a wide range of scholars interested in the intersection of archaeology, history, and network science.

The construction of 3D realities is deeply embedded in archaeological practices. From sites to artifacts, archaeology has dedicated itself to creating digital copies for the most varied purposes. The paper “Visual encoding of a 3D virtual reconstruction's 3 scientific justification: feedback from a proof-of-concept research” (Jean-Yves et al 2024) represents an advance, in the sense that it does not just deal with a three-dimensional theory for archaeological practice, but rather offers proposals regarding the epistemic component, how it is possible to represent knowledge through the workflow of 3D virtual reconstructions themselves. The authors aim to unite three main axes - knowledge modeling, visual encoding and 3D content reuse - (Jean-Yves et al 2024: 2), which, for all intents and purposes, form the basis of this article. With regard to the first aspect, this work questions how it is possible to transmit the knowledge we want to a 3D model and how we can optimize this epistemic component. A methodology based on plausibility criteria is offered, which, for the archaeological field, offers relevant space for reflection. Given our inability to fully understand the object or site that is the subject of the 3D representation, whether in space or time, building a method based on probabilistic categories is probably one of the most realistic approaches to the realities of the past.

Thus, establishing a plausibility criterion allows the user to question the knowledge that is transmitted through the representation, and can corroborate or refute it in future situations. This is because the role of reusing these models is of great interest to the authors, a perfectly justifiable sentiment, as it encourages a critical view of scientific practices. Visual encoding is, in terms of its conjunction with knowledge practices, a key element. The notion of simplicity under Maeda's (2006) design principles not only represents a way of thinking that favors operability, but also a user-friendly design in the prototype that the authors have created. This is also visible when it comes to the reuse of parts of the models, in a chronological logic: adapting the models based on architectural elements that can be removed or molded is a testament to intelligent design, whereby instead of redoing models in their entirety, they are partially used for other purposes.

All these factors come together in the final prototype, a web application that combines relational databases (RDBMS) with a data mapper (MassiveJS), using the PHP programming language.  The example used is the Marmoutier Abbey hostelry, a centuries-old building which, according to the sources presented, has evolved architecturally over several centuries ((Jean-Yves et al 2024: 8). These states of the building are represented visually through architectural elements based on their existence, location, shape and size, always in terms of what is presented as being plausible. This allows not only the creation of a matrix in which various categories are related to various architectural elements, but also a visual aid, through a chromatic spectrum, of the plausibility that the authors are aiming for. 

In short, this is an article that seeks to rethink the degree of knowledge we can obtain through 3D visualizations and that does not take models as static, but rather realities that must be explored, recycled and reinterpreted in the light of different data, users and future research. For this reason, it is a work of great relevance to theoretical advances in 3D modeling adapted to archaeology.

The production of texts in archaeology is vast and multiple in nature, and the archaeologist often misses the true extent of its scope. Machine learning and deep learning have a top place to play in these analyses (Bellat et al 2025), with text extraction methods being therefore a useful tool for reducing complexity and, more specifically, for uncovering elements that may be lost in the midst of so much literary production. This is what Van den Dikkenberg and Brandsen set out to do in the specific case of Vlaardingen Culture (3400-2500 BCE). By using NER (Named Entity Recognition) with BERT (Bidirectional Encoder Representations from Transformers) they were able to recover data related to the location of sites, the relevance of the data and, just as importantly, potential errors and failures in interpretation (Van den Dikkenberg and Brandsen 2025). The contextual aspect is emphasized here by the authors, and is one of the main reasons why BERT is used, which is logically a wake-up call for the future: it is not enough to classify or represent data, it is essential to understand what surrounds it, its contexts and its particularities (Brandsen et al 2022). 

For this, refinement is always advocated, as these models need constant attention in terms of both training data and parameters. This constant search means that this article is not simply an analysis, but that it can be a relevant contribution both to the culture in question and to the way in which we approach and extract relevant information about the grey literature that archaeology produces. Thus, Van den Dikkenberg and Brandsen present us with an article that is eminently practical but which considers the theoretical implications of this automation of the search for the contexts of archaeological data, which reinforces its relevance and, consequently, its recommendation.

The pioneering work of Leroi-Gourhan introduced archaeologists to the concept of the chaîne opératoire[1], whereby, like his supervisor Mauss[2], Leroi-Gourhan proposed direct links between bodily actions and aspects of cultural identity. The chaîne opératoire offers a powerful conceptual tool with which to reconstruct and describe the technological practices undertaken by craftspeople, linking material objects to the cultural context in which crafts are learnt. Although initially applied to lithics, the concept today is well known in ceramic studies, as well as, other material crafts, in order to identify aspects of tradition and identity through ideas linked to technological style[3,4] and communities of practice[5].

Utilizing this approach, Denis et al.[6] use the chaîne opératoire to look at both lithics and ceramics together from a diachronic viewpoint, to examine technical systems present over the transition between Linearbandkeramic (LBK) and post LBK Blicquy/Villeneuve-Saint German (BQY/VSG) timeframes. This much needed comparative and diachronic perspective, focuses on material from the sites of Vaux-et-Borset and Verlaine in Belgium, and has enabled the authors to consider the impact of changing social dynamics on these two crafts simultaneously.

The authors examine the ceramic and lithic assemblages from a macroscopic and morphological perspective in order to identify techniques of production. The data gathered testifies to the dominance of one production technique for each craft within the LBK. There is particularly striking homogeneity noted for the lithics that suggests the transmission of a single tradition over the Hesbaye area, whilst the ceramics display greater regional diversity. The picture alters somewhat for the BQY/VSG material where it seems there is an increase in the diversity of production techniques, with both the introduction of new techniques, as well as a degree of hybridization of earlier techniques to form new BQY/VSG chaînes opératoires that have LBK roots. The BQY/VSG diversity noted for the lithics is especially interesting, with the introduction of techniques that attest to increased expertise which the authors attest to the migration of an external group.

The results of this work have allowed Denis et al. to discuss multiple influences on the technical systems they identify. Rather than trying to fit the data within a single model, the authors demonstrate the need for nuance, considering the social changes associated with Neolithic migration and interactions, as multifaced and dynamic. As such, they are able to show not only the influence of contact with other groups, but that the apparent migration of external groups does not simply lead to the replacement of the crafting heritage already established at the sites they have examined.

In concluding the authors acknowledge, that as scholars push the existing state of knowledge (in this respect analysis of raw materials would make an especially important contribution), the picture presented in the paper may alter. Future work will hopefully fill in current gaps, particularly in terms of how far the trends identified extend, and the extent to which the lithic and ceramic pictures diversify on a broader geographical scale. It is certain that based on such results, future work should adopt the comparative approach presented by the authors, who have demonstrated its explanatory potential for understanding the technical and cultural groups we all study.

This article by L. Doyon et al. [1] represents an important step to the recognition of bone expedient tools within archaeological faunal assemblages, and therefore deserves publication.

In this work, the authors compare bone flakes and splinters experimentally obtained by percussion (hammerstone and anvil technique) with fossil ones coming from the Palaeolithic site of Lingjing in China. Their aim is to find some particularities to help distinguish the fossil bone fragments which were intentionally shaped, from others that result notably from marrow extraction. The presence of numerous (>6) contiguous flake scars and of a continuous size gradient between the lithics and the bone blanks used, appear to be two valuable criteria for identifying 56 bone elements of Lingjing as expedient bone tools. The latter are present alongside other bone tools used as retouchers [2].

Another important point underlined by this study is the co-occurrence of impact and flake scars among the experimentally broken specimens (~90%), while this association is seldom observed on archaeological ones. Thus, according to the authors, a low percentage of that co-occurrence could be also considered as a good indicator of the presence of intentionally shaped bone blanks.

About the function of these expedient bone tools, the authors hypothesize that they were used for in situ butchering activities. However, future experimental investigations on this question of the function of these tools are expected, including an experimental use wear program.

Finally, highlighting the presence of such a bone industry is of importance for a better understanding of the adaptive capacities and cultural practices of the past hominins. This work therefore invites all taphonomists to pay more attention to flake removal scars on bone elements, keeping in mind the possible existence of that type of bone tools. In fact, being able to distinguish between bone fragments due to marrow recovery and bone tools is still a persistent and important issue for all of us, but one that deserves great caution.
