The website was developed for floor layers (FL) working in very small businesses, in a perspective of knowledge management and transfer. Its content aims to reflect what is important to say or to know from the FLs perspectives. Thus, the content was developed with the FLs while the editing involved essentially website professionals. The aim of the paper is to point out challenges and difficulties met. In the first part of the results section, we first focus on the website's content development: FLs demands, particular development challenges and communication usages. The second section exposes the difficulties met in the transfer process with website professionals.

The emergence and success of web platforms nurtured a trend within social studies: "Hyperlink is dead!". Capturing their users into mobile applications and specialised web interface to propose them a specific user experience (and business model), the platforms indeed created new information silos in the open World Wide Web space. The simplified availability of user behavioural data through these platforms APIs reinforced this idea in academic communities by providing scholars with an easy way to collect rich user centric data for their research. After discussing the methodological aspects of the web divide between platforms and classical websites, we will argue that although it becomes more and more invisible, the hyperlink, modern incarnation of intertextual links between documents, is still a central and structural element of the web. Hyperlinks remain an invaluable resource to turn the web into a research field in spite of the complexity to collect, manipulate and curate them. We will illustrate those methodological challenges by describing the choices we made in designing Hyphe, a tool dedicated to the creation of web corpora tailored for mining hypertexts.

In this paper we present a data visualization platform designed to support the Natural Language Processing (NLP) scholar to study and analyze different corpora collected with the purpose to understand the hate speech phenomenon in social media. The project started with the creation of a corpus which collects tweets addressed to specific groups of ethnic minorities considered very controversial in the Italian public debate. Each tweet has been manually tagged with a series of attributes in order to capture the different features used to characterize the hate speech phenomenon. This corpus is mainly built to be used for training an automatic classifier and helping us in its testing and validation, before being it adopted to detect tweets targeted as hate speech on larger scale datasets. As opposed as many other traditional machine learning tasks, to build a good classifier achieving high scores in terms of accuracy is very challenging in such scenario, because of the intrinsic ambiguity of the language, the lack of a proper and explicable context in social media, and the attitude of on line users of being sarcastic and ironical. Therefore, in order to properly validate an effective feature selection process, correlations between selected attributes must be studied and analyzed. This motivated us to build an interactive platform to explore data in our corpora across the dimensions that have been used to characterize collected tweets. In our paper, after a brief introduction of the hate speech dataset, we will show how the dashboard can fit into the NLP pipeline, and how its architecture can be structured. Finally, we will present some of the challenges we have faced to visualize data with spatial, temporal and numerical attributes.

Ces dernières années, apparaissent sur le marché des drogues, de nouvelles substances psychoactives qui constituent un véritable problème de santé publique car, en absence de connaissances, il n'existe aucun moyen de les contrôler. Les organisations de santé publique portent aujourd'hui une attention particulière à l'exploitation des données du Big data, notamment du web social, afin de mieux orienter les politiques décisionnelles. Elles recherchent notamment des méthodes, des stratégies mais aussi des outils pour les « faire parler ». Notre article présente une recherche menée sur Twitter qui a pour objectif de faire « parler » les données extraites de ce réseau social et déterminer quels sont les acteurs qui communiquent autour de la problématique des nouvelles drogues et leurs messages. Notre étude révèle ainsi que ce réseau social permet aux associations, scientifiques et autres organismes de relayer un certain nombre d'informations sur les nouvelles drogues, notamment des messages de prévention, des études scientifiques ou encore des informations législatives. En revanche, ce lieu, aujourd'hui trop "ouvert", n'incite pas les usagers de drogues à y communiquer, préfèrant des lieux plus "fermés" comme les forums de discussions PsychoACTIF®ou Psychonaut®ou encore le Darknet, sur lesquels nous menons actuellement d'autres travaux pour déterminer quels sont les effets sanitaires et sociaux de ces nouvelles drogues et comment adapter les messages de prévention.

The caching of frequently requested web resources is an integral part of the web ever since. Cacheability is the main pillar for the web's scalability and an important mechanism for optimizing resource consumption and performance. Caches exist in many variations and locations on the path between web client and server with the browser cache being ubiquitous to date. Web developers need to have a profound understanding of the concepts and policies of web caching even when exploiting these advantages is not relevant. Neglecting web caching may otherwise result in more serve consequences than the simple loss of scalability and efficiency. Recent misuse of web caching systems shows to affect the application's behavior as well as privacy and security. In this paper we introduce a tool-based approach to disburden web developers while keeping them informed about caching influences. Our first contribution is a structured test suite containing 397 web caching test cases. In order to make this collection easily adoptable we introduce an automated testing tool for executing the test cases against web browsers. Based on the developed testing tool we conduct a systematic analysis on the behavior of web browser caches and their compliance with relevant caching standards. Our findings on desktop and mobile versions of Chrome, Firefox, Safari and Edge show many diversities as well as discrepancies. Appropriate tooling supports web developers in uncovering such adversities. As our baseline of test cases is specified using a specification language that enables extensibility, developers as well as administrators and researchers can systematically add and empirically explore caching properties of interest even in non-browser scenarios.

While the use of tools is not new for the sciences, the, traditionally, qualitative research methods driven humanities were using tools scarcely. The increasing use of computer-aided methods within the humanities has been summarized as 'computational turn' [36], digital humanities [4, 7], eResearch [25] and/or eHumanities [41]. In the Humanities, scholars are in the unique position to actively question the relatively new role and influence of tools on research. Such reflection, however, need not be limited to the Humanities, but holds value for both scholars and scientists. Digital tools and data have changed the production of knowledge [22, 26, 34]. Although there has been attention to biases in digital tools, discussions have been scattered not only across monographs, articles and book chapters lacking a proper label, but also tend to remain in their respective academic bubbles. Different methods have emerged, each embedded in their own fields. In this paper we reflect on the novel practices of digital methods and data analysis in the humanities and discuss the epistemic impact of knowledge technology, more generally. Consequently, this paper argues for the development of a rigorous inquiry into the tools used for research to be an essential element of the overall research process. We dub this enquiry 'tool criticism'. Tool criticism paves the way to move from digital methods [32, 33] to 'digital methodology'.

Concerning DH, interdisciplinarity carries notions as frontiers, overlapping parts of scientific fields, boundaries in historical perspectives. How should one define interdisciplinary means of working in DH? What kind of interdisciplinarity is DH about? And what disciplinary foundations should apply to it? We will first propose an overview of various definitions from the francophone DH field before presenting the Actor Network Theory. We will then introduce the digital tools and methodology developed to study the DH network in a general way. Each student conducted a micro-study with a different corpus. They are briefly exposed and their results follow. Lastly we synthetize some elements to discuss based on these studies and we draw a few perspectives to pursue this research.

In this article we describe our general approach to Web Studies. We consider the Web as a complex system and environment that might be seized from diverse entry points such as: its visuality, its technicality, and its practicality. We observe some current trends regarding the study of the Web as an object of inquiry. Our survey takes into account different perspectives and examples as they are represented in the recent edition of the International Conference on Web Studies (WS.2 2018).

This paper studies the uses of social media from a crossplatform perspective. It firstly defines the concept of crossplatform references and the different forms they can take. A set of methodological challenges that may hinder the analysis of such references is then described, alongside with some possible solutions and tools. Promising research avenues are finally presented as a potential research agenda.
