A Cloud-Native Web Application for Assisted Metadata Generation and Retrieval: THESPIAN-NER

Within the context of the Competence Centre for the Conservation of Cultural Heritage (4CH) project, the design and deployment of a platform-as-a-service cloud infrastructure for the first European competence centre of cultural heritage (CH) has begun, and some web services have been integrated into the platform. The first integrated service is the INFN-CHNet web application for FAIR storage of scientific analysis on CH: THESPIAN-Mask. It is based on CIDOC-CRM-compatible ontology and CRMhs, describing the scientific metadata. To ease the process of metadata generation and data injection, another web service has been developed: THESPIAN-NER. It is a tool based on a deep neural network for named entity recognition (NER), enabling users to upload their Italian-written report files and obtain labelled entities. Those entities are used as keywords either to serve as (semi)automatically custom queries for the database, or to fill (part of) the metadata form as a descriptor for the file to be uploaded. The services have been made freely available in the 4CH PaaS cloud platform

A Framework Design for Information Management in Heritage Science Laboratories

The dataflow in any scientific research laboratory is continuous and considerable even in analytical niches such as heritage science laboratories. This article discusses advantages of using a Laboratory Information Management System (LIMS) for organising and systematising research in an interdisciplinary analytical laboratory. LIMS solutions are proven to be effective in managing laboratories, organising their daily management tasks, improving work conditions and increasing productivity, managing equipment and resources, and managing and safeguarding scientific data. LIMS software is commercially available since the 1990s with over a hundred software packages intended either for general or specific purposes. However, the ones currently available do not fulfil all the requirements for heritage science or are over-the-top, complex, one-fits-all standard solutions. The system here proposed was developed for a heritage science laboratory, considering its unique requirements, having as a case study the HERCULES Lab, from the University of Évora (Portugal). This article documents our approach based on the analysis of the unique requirements for the lab resulting in a proposal of a custom user-centred web-based system. For this, we discuss in detail the workflow, and the required system architecture. We conclude that although it is a small niche market for major manufacturers to dwell on, a custom LIMS is of the utmost importance for the current management of heritage science laboratories across the globe

Populating the Digital Space for Cultural Heritage with Heritage Digital Twins

The present paper concerns the design of the semantic infrastructure of the digital space for cultural heritage as envisaged by the European Commission in its recent documents. Due to the complexity of the cultural heritage data and of their intrinsic interrelationships, it is necessary to introduce a novel ontology, yet compliant with existing standards and interoperable with previous platforms used in this context, such as Europeana. The digital space organization must be tailored to the methods and the theory of cultural heritage, briefly summarized in the introduction. The new ontology is based on the Digital Twin concept, i.e. the digital counterpart of cultural heritage assets incorporating all the digital information pertaining to them. This creates a Knowledge Base on the cultural heritage digital space. The paper outlines the main features of the proposed Heritage Digital Twin ontology and provides some examples of application. Future work will include completing the ontology in all its details and testing it in other real cases and with the various sectors of the cultural heritage community.Comment: Submitted to Data - An Open Access Journal from MDPI. 29 pages, 9 figure
