The CEREALAB database aims to store genotypic and phenotypic data obtained by the CEREALAB project and to integrate them with already existing data sources in order to create a tool for plant breeders and geneticists. The database can help them in unravelling the genetics of economically important phenotypic traits; in identifying and choosing molecular(More)
In many current fuzzy control papers, LMI stability conditions are devised in order to prove stability of Takagi-Sugeno fuzzy systems. Such laws are usually independent of the values of membership functions, and fulfil for multiple shapes of them. Knowledge of the shape of the membership functions may allow lifting some conservativeness. In particular, in(More)
We describe our experience in developing a Hadoop based integration flow to collect and integrate publicly available government datasets related to government spending. The objective is to enable users, U.S. taxpayers in this case, to easily access the data their government discloses on the web in different websites. We also provide users with easy-to-use(More)
In this paper we describe the development of the CEREALAB ontology, an ontology of molecular and phenotypic cereals data, realized by integrating public web databases with the database developed by the research group of the CEREALAB laboratory. Integration is obtained by using the MOMIS system (Mediator envirOnment for Multiple Information Sources), a data(More)
The paper presents the development of a virtual database for the genotypic selection of cereal cultivars starting from phenotypic traits. The database is realized by integrating two existing web databases, Gramene 1 and Graingenes , and a pre-existing data source developed by the Agrarian Faculty of the University of Modena and Reggio Emilia. The(More)
In this article we present CWSD (Combined Word Sense Disambiguation) a method and a software tool for enabling automatic annotation of local structured and semi-structured data sources, with lexical information, in a data integration system. CWSD is based on the exploitation of WordNet Domains, structural knowledge and on the extension of the lexical(More)
Data Lineage is an open research problem. This is particularly true in data integration systems, where information coming from different sources, potentially uncertain or even inconsistent with each other, is integrated. In this context, having the possibility to trace the lineage of certain data can help unraveling possible unexpected or questionable(More)
In this paper modal fuzzy quantities and an arithmetic to operate with them are introduced. Based on the identification of a fuzzy quantity with the set of predicates it accepts and rejects, a modal fuzzy quantity is defined. Modal fuzzy intervals arise as a particular case, with either existential or universal modal intervals as alpha-cuts. Modal interval(More)
