SCIENTIFIC ACTIVITIES The research of Sara Comai covers the following main topics: 1996-1998: Study of the semantics of execution of the rules of active databases and analysis of the problems of termination and confluence of such kinds of rules. In particular, the first aspect has led to the identification of several semantic dimensions of execution of the rules available in the different commercial systems and existing prototypes and to the determination of a model that describes the semantics of execution of any system of active databases. The second problem has been studied formally by exploiting the results of Datalog rules (with negation both in the body and in the head) through the definition of a model for analyzing the semantic equivalence between a system of active rules and a system based on deductive rules. Thanks to this model sufficient conditions have been identified to ensure the properties of termination and confluence of a set of active rules, characterized by several semantic dimensions. Also algorithms for the assignment of priority to the active rules have been proposed so as to satisfy the sufficient conditions for termination and confluence. 1997-2002: Visual languages for querying and restructuring XML documents. The research concerns the definition of visual modalities for querying XML data sources. The main result is the definition of XML-GL, a query language based on graphs. XML-GL is derived from an earlier search on logical languages based on graphs for querying semistructured data. XML-GL is characterized by a new syntax and semantics, suited to query XML documents. The role of XMLGL is comparable with the role of QBE in the world of relational databases: the purpose of the language is to provide a simplified paradigm for non-expert users. In particular, Sara Comai was responsible for the definition of the operational semantics of XML-GL and the study of complex type of queries. 2000-2009: Methods and tools for the specification, design and automatic generation of complex web applications (extended with Web services, workflow and exceptions).In particular, she has made a significant contribution to the language WebML, a visual notation for the conceptual specification of large Web applications, focusing on the analysis of patterns of composition and navigation of this language in order to determine properties useful for the construction of correct hypertexts. The study of WebML and of its semantics allowed her to actively participate as co-author of the book "Designing DataIntensive Web Applications" published by Morgan Kaufmann in December 2002. The book has been translated in Italian in 2003 by McGraw-Hill under the title "Design of data and applications for the Web." She has also studied several extensions of the WebML language for designing Web applications with advanced integrated workflows and Web services. Part of this research was conducted within the European project IST WebSI, funded by the European Union fifth framework project. Further results in the Web engineering field have been obtained in the study of the issues related to the presentation of Web applications. Examples of problems include: a) the semiautomatic support for the display of the information contained in the pages of a site (automatic display layout of Web pages) or for the display of the results of a search engine, using techniques based on constraint programming, or by means of systems of rules and heuristics; b) The modeling of "rich" Web interfaces based on Rich Internet Applications (or RIAs), a variant of Web-based systems that have the benefits of both desktop applications and Web applications. The research consisted in the revision of the language WebML to model also RIA applications. 2009-2012: Methods and tools for the development of haptic applications, i.e. applications relying on systems that provide force feedbacks to the user (e.g., vibrations, forces of attraction / repulsion, etc..). In particular, these systems have been applied in the education field. She has also proposed a visual language for the specification of haptic effects, which can be automatically translated into the haptic languages used by commercial haptic systems. 2012: Sara Comai collaborates with STMicroelectronics for the introduction of a relational database in an environment for the functional verification based on systems for "coveragedriven constraint-random verification", to store the data exchanged by the system components in order to perform data analysis. Since 2012 she works in the Assistive Technology Group (ATG), a multi-disciplinary working group whose mission is to “Identify, forecast, implement, promote and apply, innovative method and technology from ICT for the development of sustainable solutions for frailty (disabled, elderly, difficulties, …) which guarantees the recovery of functionality, social integration, equal opportunities, health, self determination and quality of life”. Sara is one of the coordinators of the group and contributes to the multisciplinary research with her background on data and user interfaces. Her main current activities are related to: a) the ALMA Project (2013-2016), an AAL Joint Programme, targeted at elderly and persons on a wheelchair in residences and hospitals, and aiming at providing services to support them in their mobility so that they canselect and follow an efficient and safe path to such destinations considering their needs and/or limitations or the status of the environment; b) MEP (Maps for Easy Paths) Project (2014-2016), a Polisocial multidisciplinary project (a program of social responsibility and commitment of Politecnico di Milano) coordinated by Sara Comai, which is developing a set of innovative tools and solutions for the enrichment of geographical maps with information about the accessibility of urban pedestrian for people with mobility problems; c) ADALGISA Project (2013-2015), funded by the Smart City program of Regione Lombardia, providing a set of services in a smart home for detecting users behavior and allowing persons with limited capabilities to easily interact with the system.
