Process mining is an established approach for analyzing and modeling complex business processes. In this paper we showcase ProMetheuS, a flexible and scalable suite for process mining natively designed for industrial applications. Moving from the experience of the ProM framework, the state-of-art process mining tool, ProMetheuS introduces three innovative designing elements. Firstly, ProMetheuS defines the concept of flow of mining, which is aimed at supporting the design of complex mining applications, where various mining tasks can be combined and automatically orchestrated at run-time. Secondly, ProMetheuS exports a rich set of facilities to help developers in building interactive applications providing on-the-fly feedback during analysis. Finally, behind the scenes, a powerful stream-based log-handling subsystem ensures scalability in data-intensive applications.

A Knowledge Discovery (KD) process is a complex inter-disciplinary task, where different types of techniques coexist and cooperate for the purpose of extracting useful knowledge from large amounts of data. So, it is desirable having a unifying environment, built on a formal basis, where to design and perform the overall process. In this paper we propose a general framework which formalizes a KD process as an algebraic expression, that is, as a composition of operators representing elementary operations on two worlds: the data and the model worlds. Then, we describe a KD platform, named Rialto, based on such a framework. In particular, we provide the design principles of the underlying architecture, highlight the basic features, and provide a number of experimental results aimed at assessing the effectiveness of the design choices. © 2016 Elsevier Ltd.

This paper extends state-of-the-art design methodologies for classical information systems by introducing an innovative methodology for designing service-oriented information systems. Service-oriented information systems can be viewed as information systems adhering to the novel service-oriented paradigm, to which a plethora of novel technologies, such as Web Services, Grid Services and Cloud Computing, currently marry. On the other hand, actual state-of-the-art literature encloses few papers that focus the attention on this yet-interesting research challenge. With the aim of fulfilling this gap, in this paper we provide a process-driven methodology for modeling service-oriented complex information systems, and we prove its effectiveness and reliability on a comprehensive case study represented by a real-life research project.

Logistics companies have faced in recent years the challenges imposed by globalization. The thinning of the margins and the enormous costs have forced companies to review and modify their product offerings and services and their business processes. One of the most feasible and reasonable way for improving port competitiveness of logistics companies is to make better use of available resources through the adoption of information technology. This paper presents the results of some research activities of a research project called PROMIS (logistic PROcess Management and Intelligence). The PROMIS research project has been started by the R&D.LOG (Research and Development Logistics) Consortium, that operates in the area of Gioia Tauro terminal container, and that is characterized by public-private partnerships for ICT transfer and diffusion. In particular, the paper proposes an agent-based model of the entities involved in berthing, shipping, yard planning and straddle carriers routing processes and describes its implementation as a multi-agent system using constraint programming (OPL) to find re-planning problem solutions. © Springer-Verlag Berlin 2010.

In this paper we present a successful application of logic programming for e-tourism: the iTravel system. The system exploits two technologies that are based on the state-of-the-art computational logic system DLV: (i) a system for ontology representation and reasoning, called OntoDLV; and, (ii) HiLεX a semantic information-extraction tool. The core of iTravel is an ontology which models the domain of tourism offers. The ontology is automatically populated by extracting the information contained in the tourism leaflets produced by tour operators. A set of specifically devised logic programs is used to reason on the information contained in the ontology for selecting the holiday packages that best fit the customer needs. An intuitive web-based user interface eases the task of interacting with the system for both the customers and the operators of a travel agency.

Theory and Practice of Logic Programming | Year: 2012

The seaport of Gioia Tauro is the largest transshipment terminal of the Mediterranean coast. A crucial management task for the companies operating in the seaport is team-building: the problem of properly allocating the available personnel for serving the incoming ships. Teams have to be carefully arranged in order to meet several constraints, such as allocation of employees with appropriate skills, fair distribution of the working load, and turnover of the heavy/dangerous roles. This makes team-building a hard and expensive task requiring several hours of manual preparation per day. In this paper we present a system based on Answer Set Programming for the automatic generation of the teams of employees in the seaport of Gioia Tauro. The system is currently exploited in the Gioia Tauro seaport by ICO BLG, a company specialized in automobile logistics. © Cambridge University Press 2011.

We have developed a system based on Answer Set Programming (ASP) for the automatic generation of the teams of employees in the seaport of Gioia Tauro. The problem here is to generate a correct allocation of the available personnel of the international seaport of Gioia Tauro in such a way that the right processing of the shoring cargo boats is guaranteed. To this end several constraints have to be satisfied. Depending on the size and the load of cargo boats, an appropriate number of employees of different skills is required. The selection of the employees and the role they play in the team (each employee might cover several roles according with his/her skills) are subject to many conditions (e.g., fair distribution of the working load, tournament of the heavy/dangerous roles, etc.). The system can build new teams, complete the allocation automatically when some key employees are fixed manually, and check the correctness of manually generated team, providing proper explainations if no correct team can be generated. In this application, the domain is modeled by exploiting ASP and implemented by using the ASP system DLV. A set of suitably defined logic programs is exploited for finding the desired allocation. The pure declarative nature of the language allowed us for refining and tuning both problem specifications and encodings together while interacting with the stakeholders of the seaport. It is worth noting that the possibility of modifying (by editing text files) in a few minutes a complex reasoning task (e.g. by adding new constraints), and testing it "on-site" together with the customer was a great advantage of our approach. The system is currenty exploited by the ICO BLG company at the seaport of Gioia Tauro. © 2010 Springer-Verlag.

Citizens empowerment in managing their own health process leads to increased demand in ICT services. The use of data management and communication techniques to manage information in health systems can provide benefits. Health information systems contain information to ease care access, reduce costs and make health care more efficient. In this context, we focus on the development of a framework to allow citizens in managing and sharing health related data with clinicians and with family doctors. In fact, citizens can play a crucial role in their own health care. Electronic Clinical Records (ECR) contain all information regarding their own clinical related data which can hence be made available for sharing and management. This work presents LiSE (for Libretto Sanitario Elettronico, health personalized booklet), a system implemented for the Smart Health 2.0 Project, as an instrument of citizen/patient empowerment for managing his own care process and for communicating information with family doctors. LiSE is a health information system for clinical data information management, annotated by citizens, overcoming the lack of communication protocols in the other systems currently in use. We report the LiSE structure, we sketch the practical clinical applications and we report user experiences. © 2015 IEEE.
