About me

Short Biography

I received my PhD in information engineering at the University of Modena and Reggio Emilia in 2003. From November 2005 to Jun 2012, I was a researcher on computer science at the Faculty of Economics of the University of Modena and Reggio Emilia, where I taught computer science and enterprise information. Since July 2012 I'm a researcher on computer science at the Department of Engineering "Enzo Ferrari" at the University of Modena and Reggio, where I teach BigData Analysis.

My main research interests include integration of heterogeneous information sources, intelligent software agents, Semantic Web and keyword-base searches. Among his research activities, the main results are: (i) MOMIS, a mediator based system for the integration of data sources. MOMIS has also been exploited in the Semantic Web, as a tool for the creation and the integration of ontologies. (ii) RELEVANT, a set of techniques for the identification of "relevant values" among those contained in the domain of attributes of data sources. (iii) KEYMANTIC/KEYRY/QUEST, three keyword-based search engines over semistructured databases exploiting semantic techniques.

I participated in Italian and European projects:

  1. the Italian PRIN WISDOM (Web Intelligent Search based on DOMain ontologies) project –years 2004-2006, where he worked on the project themes: Creation and update of a Domain Ontology, Emergent Semantics: discovering semantic mappings amongst domain ontologies and he supported the coordination of the activities.
  2. the European SEWASIE project (SEmantic Web and AgentS in Integrated Economies) - years 2002-2005, where, in particular, he worked on WP2 (semantic enrichment and integration) to define semantic enrichment processes for information sources and to develop the virtual data stores which constitute the information nodes accessible by the users; and on WP10 (Project management) where he took charge of the publishing of the final report and the showcase.
  3. the EU Project STASIS Software for Ambient Semantic Interoperable Services (years 2006-2009), which allows SMEs to participate in the e-Economy by offering a coherent set of semantic applications.
  4. the Italian FIRB NEP4B: Networked Peers for Business (years 2006-2009) that developed an infrastructure to enable companies of any nature, size and location to search for partners, exchange data and collaborate. He was involved in WP2 Design of single peer functional architecture, WP3 Prototyping and Validation, WP5 Dissemination and exploitation (Responsible person for UNIMORE) and WP6 Project management (he supported the Coordinator’s tasks).
  5. the local project: Searching for a needle in mountains of data (years 2008-2010), funded by the Fondazione Cassa di Risparmio di Modena, addressing the issue of easily querying a mediator based system.
  6. the COST Action KEYSTONE semantic KEYword-based Search on sTructured data sOurcEs (IC1302), years 2013-2017, where I'm the Chair of the Management Committee.

Research

Interests

Since 2001, when I started to research during my PhD, my activity has mainly dealt with information management, integration of heterogeneous information sources, semantics, ontologies, keyword-based search and the Semantic Web.

The main topics that I have addressed in my research up till now are:

  1. Intelligent Integration of Information and Semantic Web
  2. Software agents and data integration
  3. Keyword search on structured databases

1. Intelligent Integration of Information and Semantic Web
A large amount of structured data is currently available, mainly in relational and RDF formats. In this context, the integration of data from heterogeneous data sources is a major challenge that the research community in databases and artificial intelligence has been addressing. In this area, I participated in the development of MOMIS (Mediator Environment for Multiple Information Sources), a mediator system that aims to provide a uniform interface for accessing and querying heterogeneous information sources.
In this field, my research dealt with the following aspects: 1) Definition of the functional specifications of the MOMIS architecture; 2) Exploitation of a mediator based system in the area of e-commerce; 3) Data integration in the case of data evolution; 4) Exploitation of virtual views built with a data integration system as domain ontologies; 5) Development of techniques for the semi-automatic annotation of sources; 6) Summarization of the domain of an attribute with a subset of its values; 7) Integration of data and multimedia sources; 8) Integration of data and web services.

2. Software agents and data integration
He participated in the development of MIKS (Mediator agent for Integration of Knowledge Sources), which is the implementation of the MOMIS data integration system with the use of agent technology to improve access and querying of semi-structured sources.

3. Keyword search on structured databases
The more the relational data complexity is increasing and the user base is shifting towards the less technically skilled, the more the keyword searching is becoming an attractive alternative to traditional SQL queries, mainly due to its simplicity. Unfortunately, this simplicity comes with the price of inherent ambiguity. Thus, the challenge of answering a keyword query over a relational database is to discover the database structures that contain the keywords and explore how these structures are inter-connected to form an answer. The discovered structures, alongside their inter-connections, are actually representing in relational terms the semantic interpretation of the keyword query. Three approaches have been developed for addressing this issue: KEYMANTIC, KEYRY and QUEST, based on an extension of the Hungarian Algorithm, on a Hidden Markov Model, on different probabilistic frameworks fused with a Dempster-Shafer based approach, respectively.

Main Results

  • RELEVANT - RELEvant VAlues geNeraTor

    Research on data integration has provided languages and systems able to guarantee an integrated intensional representation of a given set of data sources. A significant limitation common to most proposals is that only intensional knowledge is considered, with little or no consideration for extensional knowledge. We developed a technique to enrich the intension of an attribute with a new sort of metadata: the "relevant values", extracted from the attribute values. Relevant values enrich schemata with domain knowledge; moreover they can be exploited by a user in the interactive process of creating/refining a query. The technique, fully implemented in a prototype, is automatic, independent of the attribute domain and it is based on data mining clustering techniques and emerging semantics from data values. It is parametrized with various metrics for similarity measures and is a viable tool for dealing with frequently changing sources, as in the Semantic Web context.

  • Keyword Search over structured databases

Keyword queries offer a convenient alternative to traditional SQL in querying relational databases with large, often unknown, schemas and instances. The challenge in answering such queries is to discover their intended semantics, construct the SQL queries that describe them and used them to retrieve the respective tuples. Existing approaches typically rely on indices built a-priori on the database content. This seriously limits their applicability if a-priori access to the database content is not possible. Examples include the on-line databases accessed through web interface, or the sources in information integration systems that operate behind wrappers with specific query capabilities. Furthermore, existing literature has not studied to its full extend the inter-dependencies across the ways the different keywords are mapped into the database values and schema elements. In this research, we developed techniques and prototypes which are mainly based on metadata.

  • KEYSTONE COST Action (IC1302)

The main objective of the Action is to launch and establish a cooperative network of researchers, practitioners, and application domain specialists working in fields related to semantic data management, the Semantic Web, information retrieval, artificial intelligence, machine learning and natural language processing, that coordinates collaboration among them to enable research activity and technology transfer in the area of keyword-based search over structured data sources. The coordination effort will promote the development of a new revolutionary paradigm that provides users with keyword-based search capabilities for structured data sources as they currently do with documents. Furthermore, it will exploit the structured nature of data sources in defining complex query execution plans by combining partial contributions from different sources.

The main objective of the Action is complemented by the following secondary objectives:

  1. Promote the development of novel techniques for keyword-based search over structured data sources.
  2. Facilitate the transfer of knowledge and technology to the scientific community, practitioners and the enterprises.
  3. Build a critical mass of research activities and outcomes that achieve the sustainability of the research themes beyond the Action
