RDF* Graph Database as Interlingua for the TextWorld Challenge
2019
This paper briefly describes the top-scoring submission to the First TextWorld Problems: A Reinforcement and Language Learning Challenge. To alleviate the partial observability problem, characteristic to the TextWorld games, we split the Agent into two independent components: Observer and Actor, communicating only via the Interlingua of the RDF* graph database. The RDF* graph database serves as the “world model” memory incrementally updated by the Observer via FrameNet informed Natural Language Understanding techniques and is used by the Actor for the efficient exploration and planning of the game Action sequences. We find that the deep-learning approach works best for the Observer componen…
Enabling Primary and Specialist Care Interoperability Through HL7 CDA Release 2 and the Chronic Care Model: An Italian Case Study
2012
Interoperability is the key to enable clinical information systems for General Practitioners (GP) and Hospital Specialists (HS) in order to exchange and manage the Chronic Care Models (CCM) medical records, Patient Summary (PS), and Electronic Prescription (e-Prescription) documents while accessing the electronic health record. We present a localization experience for PS and e-prescription, based on the Health Level Seven Version 3 Clinical Document Architecture Release 2, developed for Italian healthcare. We describe also an experience on the implementation of CCM for sharing patient clinical data among healthcare providers in the management of diagnostic and therapeutic pathways for chron…
HL7v3 CDA Rel.2 prescription: Localization experience and GP Integration Project
2010
The localization experience for the e-prescription, based on the Health Level Seven Version 3 (HL7v3) Clinical Document Architecture, Release 2 (CDA Rel.2), is presented. As application, we propose a project of General Practitioners Integration with the EHR (Electronic Health Record), implementing the e-prescription, patient summary and other CDA Rel.2 documents. The integration is made possible with HL7v3, the most widely used standard for healthcare information interoperability. The project is in line with the state of the art in the normative referring context for the Italian Healthcare, both at national and regional level (Tuscany Region). Final remarks are drawn, also referring to the …
Knowledge Representation on the Web Revisited: The Case for Prototypes
2016
Recently, RDF and OWL have become the most common knowledge representation languages in use on the Web, propelled by the recommendation of the W3C. In this paper we examine an alternative way to represent knowledge based on Prototypes. This Prototype-based representation has different properties, which we argue to be more suitable for data sharing and reuse on the Web. Prototypes avoid the distinction between classes and instances and provide a means for object-based data sharing and reuse.
Digital signal processing for relaxation data conversion
2005
Abstract The origins, philosophy and basic practical aspects are considered for an approach of digital data transformations for broadband dielectric relaxation spectroscopy and other relaxation experiments carrying out direct and inverse integral transforms with kernels depending on the ratio or product of arguments. The approach is based on the concept that the mentioned data transformations represent a filtering problem on a logarithmic scale allowing one to implement the transforms by digital functional filters with the logarithmic sampling. As an example, digital Kramers–Kronig transformers are considered.
Statistical Modeling of Huffman Tables Coding
2005
An innovative algorithm for automatic generation of Huffman coding tables for semantic classes of digital images is presented. Collecting statistics over a large dataset of corresponding images, we generated Huffman tables for three images classes: landscape, portrait and document. Comparisons between the new tables and the JPEG standard coding tables, using also different quality settings, have shown the effectiveness of the proposed strategy in terms of final bit size (e.g. compression ratio).
Structural characterization of CspZ, a complement regulator factor H and FHL-1 binding protein fromBorrelia burgdorferi
2014
Borrelia burgdorferi is the causative agent of Lyme disease and is found in two different types of hosts in nature - Ixodes ticks and various mammalian organisms. To initiate disease and survive in mammalian host organisms, B. burgdorferi must be able to transfer to a new host, proliferate, attach to different tissue and resist the immune response. To resist the host's immune response, B. burgdorferi produces at least five different outer surface proteins that can bind complement regulator factor H (CFH) and/or factor H-like protein 1 (CFHL-1). The crystal structures of two uniquely folded complement binding proteins, which belong to two distinct gene families and are not found in other bac…
A MIDI sequencer that widens access to the compositional possibilities of novel tunings
2012
We present a new Dynamic Tonality MIDI sequencer, Hex, that aims to make sequencing music in and across a large variety of novel tunings as straightforward as sequencing in twelve-tone equal temperament. It replaces the piano roll used in conventional MIDI sequencers with a two-dimensional lattice roll in order to enable the intuitive visualization and dynamic manipulation of tuning.\ud \ud In conventional piano roll sequencers, a piano keyboard is displayed on the left side of the window, and white and black note lanes extend horizontally to the right, into which a user can draw a sequence of notes. Similarly, in Hex, a button lattice is displayed in its own pane on the left side of the wi…
How Much Are We Willing To Lose in Cyberspace? On the Tail Risk of Scam in the Market for Initial Coin Offerings
2020
From an entrepreneurial perspective, Initial Coin Offering (ICO) has become an alternative way for attaining funding for business projects using the new evolving digital financial market for tokens. Unfortunately, the majority of all ICOs are subject to scam which casts doubt on this new innovative tool for acquiring funding. Using a unique intensively hand-collected data set covering more than 5000 ICOs which have been launched in the August 2014–December 2019 period, we could identify 1014 ICOs exhibiting data on raised funding whereof 576 turned out to be scams projects. The cumulative losses due to scam in the ICO market correspond to $10.12 billion which is 66% of our identified overal…
Data analytics in banks' audit: The case of loan loss provisions in Uruguay
2016
Abstract The purpose of this study is two-fold: firstly, to analyze the benefits of implementing an enterprise resource planning (ERP) system and using eXtensible Business Reporting Language (XBRL) format to report in the banking industry considering the industry's specific risks and complexities. Secondly, to show that both, ERP and XBRL are necessary to successfully use Computer Assisted Audit Techniques (CAATs) while performing audit procedures to verify the compliance of certain crucial regulatory requirements. The study shows the possible consequences of not using CAATs to audit the compliance of loan loss provisions' regulatory requirements in Uruguay.
