- From Sensors Data to Urban Traffic Flow Analysis
[Relazione in Atti di Convegno]
Po, Laura; Rollo, Federica; Bachechi, Chiara; Corni, Alberto
abstract
By 2050, almost 70% of the population will live in cities. As the population grows, travel demand increases and this might affect air quality in urban areas. Traffic is among the main sources of pollution within cities. Therefore, monitoring urban traffic means not only identifying congestion and managing accidents but also preventing the impact on air pollution. Urban traffic modeling and analysis is part of the advanced traffic intelligent management technologies that has become a crucial sector for smart cities. Its main purpose is to predict congestion states of a specific urban transport network and propose improvements in the traffic network that might result into a decrease of the travel times, air pollution and fuel consumption. This paper describes the implementation of an urban traffic flow model in the city of Modena based on real traffic sensor data. This is part of a wide European project that aims at studying the correlation among traffic and air pollution, therefore at combining traffic and air pollution simulations for testing various urban scenarios and raising citizen awareness about air quality where necessary.

- MOMIS Goes Multimedia: WINDSURF and the Case of Top-K Queries
[Relazione in Atti di Convegno]
Bartolini, Iaria; Beneventano, Domenico; Bergamaschi, Sonia; Ciaccia, Paolo; Corni, Alberto; Orsini, Mirko; Patella, Marco; Santese, MARCO MARIA
abstract
In a scenario with “traditional” and “multimedia” data sources, this position paper discusses the following question: “How can a multimedia local source (e.g., Windsurf) supporting ranking queries be integrated into a mediator system without such capabilities (e.g., MOMIS)?” More precisely, “How to support ranking queries coming from a multimedia local source within a mediator system with a “traditional” query processor based on an SQL-engine?” We first describe a na¨ıve approach for the execution of range and Top-K global queries where the MOMIS query processing method remains substantially unchanged, but, in the case of Top-K queries, it does not guarantee to obtain K results. We then discuss two alternative modalities for allowing MOMIS to return the Top-K best results of a global query.

- The Open Source release of the MOMIS Data Integration System
[Relazione in Atti di Convegno]
Bergamaschi, Sonia; Beneventano, Domenico; Corni, Alberto; Entela, Kazazi; Orsini, Mirko; Po, Laura; Sorrentino, Serena
abstract
MOMIS (Mediator EnvirOnment for Multiple InformationSources) is an Open Source Data Integration system able to aggregate data coming from heterogeneous data sources (structured and semistructured) in a semi-automatic way. DataRiver3 is a Spin-Off of the University of Modena and Reggio Emilia that has re-engineered the MOMIS system, and released its Open Source version both for commercial and academic use. The MOMIS system has been extended with a set of features to minimize the integration process costs, exploiting the semantics of the data sources and optimizing each integration phase.The Open Source MOMIS system have been successfully applied in several industrial sectors: Medical, Agro-food, Tourism, Textile, Mechanical, Logistics. This paper describes the features of the Open Source MOMIS system and how it is able to address real data integration challenges.

- Uncertainty in data integration systems: automatic generation of probabilistic relationships
[Relazione in Atti di Convegno]
Bergamaschi, Sonia; Po, Laura; Sorrentino, Serena; Corni, Alberto
abstract
This paper proposes a method for the automatic discovery of probabilistic relationships in the environment of data integration systems. Dynamic data integration systems extend the architecture of current data integration systems by modeling uncertainty at their core. Our method is based on probabilistic word sense disambiguation (PWSD), which allows to automatically lexically annotate (i.e. to perform annotation w.r.t. a thesaurus/lexical resource) the schemata of a given set of data sources to be integrated. From the annotated schemata and the relathionships defined in the thesaurus, we derived the probabilistic lexical relationships among schema elements. Lexical relationships are collected in the Probabilistic Common Thesaurus (PCT), as well as structural relationships.

- ALA: Dealing with Uncertainty in Lexical Annotation
[Software]
Bergamaschi, Sonia; Po, Laura; Sorrentino, Serena; Corni, Alberto
abstract
We present ALA, a tool for the automatic lexical annotation (i.e. annotation w.r.t. a thesaurus/lexical resource) of structured and semi-structured data sources and the discovery of probabilistic lexical relationships in a data integration environment. ALA performs automatic lexical annotation through the use of probabilistic annotations, i.e. an annotation is associated to a probability value. By performing probabilistic lexical annotation, we discover probabilistic inter-sources lexical relationships among schema elements. ALA extends the lexical annotation module of the MOMIS data integration system. However, it may be applied in general in the context of schema mapping discovery, ontology merging and data integration system and it is particularly suitable for performing “on-the-fly” data integration or probabilistic ontology matching.

- SI-Designer: a tool for intelligent integration of information
[Relazione in Atti di Convegno]
Beneventano, Domenico; Bergamaschi, Sonia; I., Benetti; Corni, Alberto; Guerra, Francesco; G., Malvezzi
abstract
SI-Designer (Source Integrator Designer) is a designer supporttool for semi- automatic integration of heterogeneoussources schemata (relational, object and semi structuredsources); it has been implemented within the MOMIS projectand it carries out integration following a semantic approachwhich uses intelligent Description Logics-based techniques,clustering techniques and an extended ODMG-ODL language,ODL-I3, to represent schemata, extracted, integratedinformation. Starting from the sources’ ODL-I3 descriptions(local schemata) SI-Designer supports the designer inthe creation of an integrated view of all the sources (globalschema) which is expressed in the same ODL-I3 language.We propose SI-Designer as a tool to build virtual catalogsin the E-Commerce environment.

- Information integration - the MOMIS project demostration
[Relazione in Atti di Convegno]
Beneventano, Domenico; Bergamaschi, Sonia; S., Castano; Corni, Alberto; G., Guidetti; M., Malvezzi; M., Melchiori; Vincini, Maurizio
abstract
The goal of this demonstration is to present the main features of a Mediator component, Global Schema Builder of an I3 system, called MOMIS (Mediator envirOnment for Multiple Information Sources). MOMIS has been conceived to provide an integrated access to heterogeneous information stored in traditional databases (e.g., relational, object- oriented) or file systems, as well as in semistructured sources. The demonstration is based on the integration of two simple sources of different kind, structured and semi-structured.

- SI-DESIGNER: un tool di ausilio all'integrazione intelligente di sorgenti di informazione
[Relazione in Atti di Convegno]
Beneventano, Domenico; Bergamaschi, Sonia; Corni, Alberto; R., Guidetti; G., Malvezzi
abstract
SI-Designer (Source Integrator Designer) e' un tool di supporto al progettista per l'integrazione semi-automatica di schemi di sorgenti eterogenee (relazionali, oggetti e semistrutturate). Realizzato nell'ambito del progetto MOMIS, SI-Designer esegue l'integrazione seguendo un approccio semantico che fa uso di tecniche intelligenti basate sulla Description Logics OLCD, di tecniche di clustering e di un linguaggio object-oriented per rappresentare le informazioni estratte ed integrate, ODLII3, derivato dallo standard ODMG. Partendo dalle descrizioni delle sorgenti in ODLII3 (gli schemi locali) SI-Designer assiste il progettista nella creazione di una vista integrata di tutte le sorgenti (schema globale) anch'essa espressa in linguaggio ODLII3.
