“…An ontology consists of a collection of concepts and relationships for conceptualizing a domain, in our case contracts. The ontology we adopt has been proposed in [9] for the Symboleo contract specification language and is shown in Figure 1. The ontology is based on the Core Legal Ontology UFO-L [10] and was developed in consultation with legal experts incorporating Hohfeld's theory of legal positions [11] but without some of its shortcomings to address contract specific elements.…”

The aim of the research is to semi-automate the process of generating formal specifications from legal contracts in natural language text form. Towards this end, the paper presents a tool, named ContrattoA, that semi-automatically conducts semantic annotation of legal contract text using an ontology for legal contracts. ContrattoA was developed through two iterations where lexical patterns were defined for legal concepts and their effectiveness was evaluated with experiments. The first iteration was based on a handful of sample contracts and resulted in defining lexical patterns for recognizing concepts in the ontology; these were evaluated with an empirical study where one group of subjects was asked to annotate legal text manually, while a second group edited the annotations generated by ContrattoA. The second iteration focused on the lexical patterns for the core contract concepts of obligation and power where results of the first iteration were mixed. On the basis of an extended set of sample contracts, new lexical patterns were derived and those were shown to substantially improve the performance of ContrattoA, nearing in quality the performance of experts. The experiments suggest that good quality annotations can be generated for a broad range of contracts with minor refinements to the lexical patterns.

“…In the early 2000s, the European-Canadian Tropos project network [26] investigated formal methods and supporting tools for how to map an i* model to operational MAS specifications, ranging from classical system dynamics simulations to contract nets, as discussed in Section 2.1, to declarative workflow languages such as ConGolog [45]. Specific research addressed the management of trust and distrust among agents [45] and, later, also multi-criteria decision support for choosing among competing ways to satisfy tasks while preserving legal regulations such as security, privacy, financial, or sustainability goals [58,59].…”

Digital twins are emerging as a prime analysis, prediction, and control concepts for enabling the Industrie 4.0 vision of cyber-physical production systems (CPPSs). Today’s growing complexity and volatility cannot be handled by monolithic digital twins but require a fundamentally decentralized paradigm of cooperating digital twins. Moreover, societal trends such as worldwide urbanization and growing emphasis on sustainability highlight competing goals that must be reflected not just in cooperating but also competing digital twins, often even interacting in “coopetition”. This paper argues for multi-agent systems (MASs) to address this challenge, using the example of embedding industrial digital twins into an urban planning context. We provide a technical discussion of suitable MAS frameworks and interaction protocols; data architecture options for efficient data supply from heterogeneous sensor streams and sovereignty in data sharing; and strategic analysis for scoping a digital twin systems design among domain experts and decision makers. To illustrate the way still in front of research and practice, the paper reviews some success stories of MASs in Industrie/Logistics 4.0 settings and sketches a comprehensive vision for digital twin-based holistic urban planning.
