  • A Framework for Ontology-Based Library Data Generation, Access and Exploitation
    Universidad Politécnica de Madrid Departamento de Inteligencia Artificial DOCTORADO EN INTELIGENCIA ARTIFICIAL A framework for ontology-based library data generation, access and exploitation Doctoral Dissertation of: Daniel Vila-Suero Advisors: Prof. Asunción Gómez-Pérez Dr. Jorge Gracia 2 i To Adelina, Gustavo, Pablo and Amélie Madrid, July 2016 ii Abstract Historically, libraries have been responsible for storing, preserving, cata- loguing and making available to the public large collections of information re- sources. In order to classify and organize these collections, the library commu- nity has developed several standards for the production, storage and communica- tion of data describing different aspects of library knowledge assets. However, as we will argue in this thesis, most of the current practices and standards available are limited in their ability to integrate library data within the largest information network ever created: the World Wide Web (WWW). This thesis aims at providing theoretical foundations and technical solutions to tackle some of the challenges in bridging the gap between these two areas: library science and technologies, and the Web of Data. The investigation of these aspects has been tackled with a combination of theoretical, technological and empirical approaches. Moreover, the research presented in this thesis has been largely applied and deployed to sustain a large online data service of the National Library of Spain: datos.bne.es. Specifically, this thesis proposes and eval- uates several constructs, languages, models and methods with the objective of transforming and publishing library catalogue data using semantic technologies and ontologies. In this thesis, we introduce marimba-framework, an ontology- based library data framework, that encompasses these constructs, languages, mod- els and methods.

  • Collecting Activity Data Using the Open Mhealth Platform an Exploratory Study on Integrating Objective Data with Sport Monitoring Systems
    Collecting activity data using the Open mHealth platform An exploratory study on integrating objective data with sport monitoring systems Daniel Gynnild-Johnsen , Lars-Erik Holte Master’s Thesis Spring 2017 Collecting activity data using the Open mHealth platform Daniel Gynnild-Johnsen Lars-Erik Holte May 2, 2017 Abstract Football players works together as a unit to perform on an elite competi- tive level, and the most minor abnormalities can determine the outcome of a match. Success can often be the result of healthy, uninjured and rejuve- nated players working together as a collective. Even though it is impossible to control all outcomes and scenarios, the risk of failure might be mini- mized by monitoring players closely on an individual level. If we monitor players over a longer period of time we might discover patterns or abnor- malities in their training. This information can be used to avoid multiple scenarios related to fatigue, injuries and overtraining. In this thesis we present a proof of concept for expanding an existing self- reporting monitoring system called pmSys, and look at how football teams and players can utilize modern technology like phones and wearable de- vices to capture objective data. This system will collect and store the data, which can be processed into useful visualised feedback, and help a team to evaluate their players. This way the coaches can make mitigating mea- sures to improve certain aspect that might be lacking on a player or team level. By eliminating the use of pen and paper, pmSys introduces a simpler way of reporting the players’ health status.

  • Schema Profiling of Document-Oriented Databases$,$$
    Schema Profiling of Document-Oriented DatabasesI,II Enrico Gallinucci, Matteo Golfarelli, Stefano Rizzi∗ DISI { University of Bologna, Viale Risorgimento 2, 40136 Bologna, Italy CINI, Via Salaria 113, 00198 Roma, Italy Abstract In document-oriented databases, schema is a soft concept and the documents in a collection can be stored using different local schemata. This gives designers and implementers augmented flexibility; however, it requires an extra effort to understand the rules that drove the use of alternative schemata when sets of doc- uments with different |and possibly conflicting— schemata are to be analyzed or integrated. In this paper we propose a technique, called schema profiling, to explain the schema variants within a collection in document-oriented databases by capturing the hidden rules explaining the use of these variants. We express these rules in the form of a decision tree (schema profile). Consistently with the requirements we elicited from real users, we aim at creating explicative, precise, and concise schema profiles. The algorithm we adopt to this end is inspired by the well-known C4.5 classification algorithm and builds on two original features: the coupling of value-based and schema-based conditions within schema profiles, and the introduction of a novel measure of entropy to assess the quality of a schema profile. A set of experimental tests made on both synthetic and real datasets demonstrates the effectiveness and efficiency of our approach. Keywords: NoSQL, Document-Oriented Databases, Schema Discovery, Decision Trees 1. Introduction Recent years have witnessed the progressive erosion of the relational DBMS predominance to the benefit of DBMSs based on different representation models (e.g., document-oriented and graph-based).

  • Designing Data Marts for Data Warehouses
    Designing Data Marts for Data Warehouses ANGELA BONIFATI Politecnico di Milano FABIANO CATTANEO Cefriel STEFANO CERI Politecnico di Milano ALFONSO FUGGETTA Politecnico di Milano and Cefriel and STEFANO PARABOSCHI Politecnico di Milano Data warehouses are databases devoted to analytical processing. They are used to support decision-making activities in most modern business settings, when complex data sets have to be studied and analyzed. The technology for analytical processing assumes that data are presented in the form of simple data marts, consisting of a well-identified collection of facts and data analysis dimensions (star schema). Despite the wide diffusion of data warehouse technology and concepts, we still miss methods that help and guide the designer in identifying and extracting such data marts out of an enterprisewide information system, covering the upstream, requirement-driven stages of the design process. Many existing methods and tools support the activities related to the efficient implementation of data marts on top of specialized technology (such as the ROLAP or MOLAP data servers). This paper presents a method to support the identification and design of data marts. The method is based on three basic steps. A first top-down step makes it possible to elicit and consolidate user requirements and expectations. This is accomplished by exploiting a goal-oriented process based on the Goal/Question/Metric paradigm developed at the University of Maryland. Ideal data marts are derived from user requirements. The second bottom-up step extracts candidate data marts The editorial processing for this paper was managed by Axel van Lamsweerde. Authors’ addresses: A.

  • Educare: a Decision Support System for Anticipating Behaviors Among Educational Actors
    educare: a decision support system for anticipating behaviors among educational actors Cláudia Antunes Instituto Superior Técnico, Av Rovisco Pais, 1049-001 Lisboa, Portugal [email protected] Abstract. Decision support systems play a core role in data management, due to its ability to provide the tools needed to help in the decision making process. Education is just another application field, where those systems may contribute to assist in its improvement. The educare project aims to design a decision support system, specifically created for enabling the discovery of hidden information about students and teachers performance. Keywords: Decision support systems, Educational data mining, Multi- dimensional model for education 1 Introduction The educational process produces amounts of data, which can and should be used to understand its actors’ behaviors and to identify failure and success causes. Despite data is collected for years, even in digital storages, education poses a set of particular challenges in respect to data analysis and information discovery. Educational Data Mining (EDM) [1] is an emerging discipline with the goal of applying DM (DM) techniques to data that come from educational settings, like computer-based tutoring systems or the traditional teaching process. In either cases, data hide students’ usual behaviors, process definitions and coordination, teaching strategies and so on. In all these cases, data are framed in a particular and well- defined context, which can and should be used to better understand the data. The reason for creating a dedicated discipline results from the identification of a set of peculiarities that characterize educational data, in particular: the temporality of records, the impact of previous events (data) on the results that occur in the future, and the impact of the context on behaviors.
