In: Information processing and management. 54(2018) no.6, S.1077-1100.
Abstract: Information Retrieval (IR) develops complex systems, constituted of several components, which aim at returning and optimally ranking the most relevant documents in response to user queries. In this context, experimental evaluation plays a central role, since it allows for measuring IR systems effectiveness, increasing the understanding of their functioning, and better directing the efforts for improving them. Current evaluation methodologies are limited by two major factors: (i) IR systems are evaluated as "black boxes", since it is not possible to decompose the contributions of the different components, e.g., stop lists, stemmers, and IR models; (ii) given that it is not possible to predict the effectiveness of an IR system, both academia and industry need to explore huge numbers of systems, originated by large combinatorial compositions of their components, to understand how they perform and how these components interact together. We propose a Combinatorial visuaL Analytics system for Information Retrieval Evaluation (CLAIRE) which allows for exploring and making sense of the performances of a large amount of IR systems, in order to quickly and intuitively grasp which system configurations are preferred, what are the contributions of the different components and how these components interact together. The CLAIRE system is then validated against use cases based on several test collections using a wide set of systems, generated by a combinatorial composition of several off-the-shelf components, representing the most common denominator almost always present in English IR systems. In particular, we validate the findings enabled by CLAIRE with respect to consolidated deep statistical analyses and we show that the CLAIRE system allows the generation of new insights, which were not detectable with traditional approaches.

2Santucci, G.: ¬The information society and the challenge for Europe.
In: Managing information. 2(1995) nos.1/2, S.20,22-24.
Abstract: The digital revolution and the convergence of information and communications technologies are triggering structural changes that affect both the economy and society and present Europe with a minor challenge. Describes the milestones in the outline of a European vision of the information society and draws attention to the Information Society Project Office, an instrument created by the European Commission (EC) to respond to the needs of member states. Argues that the key to success involves the deployment of technology based applications for the information society. Identifies 10 priority applications, outlines the EC contribution which will include initiative building and partnership building, and discusses key activities for promoting the applications
4Santucci, G.: Information highways worldwide : challenges and strategies.
In: FID news bulletin. 44(1994) no.10, S.237-247.
Abstract: Information highways which have now become the first legendary step towards the information society highlight 3 key facts against the backdrop of globalization and economic and social crisis: the technoindustrial system has entered a new age, that of information and communication; the transition to this new era brings in its wake major industrial and also economic and social challenges; and the successful accomplishment of this transition requires a fresh equilibrium between the private and public sectors. Discusses these key facts focusing on where and how the USA, Japan and Europe stand in the public sector/private sector debate
