Types and Annotations for CIDOC CRM Properties

The CIDOC CRM provides an extensive ontology for describing entities and properties appearing in cultural heritage (CH) documentation, history and archeology. CRM provides some means for describing information about properties (property types, attribute assignment, and "long-cuts") and guidelines for extending the vocabulary. However, these means are far from complete, and in some cases there is little guidance how to "implement" them in RDF. In this article we outline the problems, relate them to established RDF patterns and mechanisms, and describe several implementation alternatives

Europeana Creative. EDM Endpoint. Custom Views

The paper discusses the Europeana Creative project which aims to facilitate re-use of cultural heritage metadata and content by the creative industries. The paper focuses on the contribution of Ontotext to the project activities. The Europeana Data Model (EDM) is further discussed as a new proposal for structuring the data that Europeana will ingest, manage and publish. The advantages of using EDM instead of the current ESE metadata set are highlighted. Finally, Ontotext’s EDM Endpoint is presented, based on OWLIM semantic repository and SPARQL query language. A user-friendly RDF view is presented in order to illustrate the possibilities of Forest - an extensible modular user interface framework for creating linked data and semantic web applications

The euBusinessGraph ontology: A lightweight ontology for harmonizing basic company information

Company data, ranging from basic company information such as company name(s) and incorporation date to complex balance sheets and personal data about directors and shareholders, are the foundation that many data value chains depend upon in various sectors (e.g., business information, marketing and sales, etc.). Company data becomes a valuable asset when data is collected and integrated from a variety of sources, both authoritative (e.g., national business registers) and non-authoritative (e.g., company websites). Company data integration is however a difficult task primarily due to the heterogeneity and complexity of company data, and the lack of generally agreed upon semantic descriptions of the concepts in this domain. In this article, we introduce the euBusinessGraph ontology as a lightweight mechanism for harmonising company data for the purpose of aggregating, linking, provisioning and analysing basic company data. The article provides an overview of the related work, ontology scope, ontology development process, explanations of core concepts and relationships, and the implementation of the ontology. Furthermore, we present scenarios where the ontology was used, among others, for publishing company data (business knowledge graph) and for comparing data from various company data providers. The euBusinessGraph ontology serves as an asset not only for enabling various tasks related to company data but also on which various extensions can be built upon.publishedVersio

The health care and life sciences community profile for dataset descriptions

Access to consistent, high-quality metadata is critical to finding, understanding, and reusing scientific data. However, while there are many relevant vocabularies for the annotation of a dataset, none sufficiently captures all the necessary metadata. This prevents uniform indexing and querying of dataset repositories. Towards providing a practical guide for producing a high quality description of biomedical datasets, the W3C Semantic Web for Health Care and the Life Sciences Interest Group (HCLSIG) identified Resource Description Framework (RDF) vocabularies that could be used to specify common metadata elements and their value sets. The resulting guideline covers elements of description, identification, attribution, versioning, provenance, and content summarization. This guideline reuses existing vocabularies, and is intended to meet key functional requirements including indexing, discovery, exchange, query, and retrieval of datasets, thereby enabling the publication of FAIR data. The resulting metadata profile is generic and could be used by other domains with an interest in providing machine readable descriptions of versioned datasets

Evaluation of the efficacy of the Baska Mask

The Baska mask is a new supraglottic airway device (SAD). Its novel features include a non-inflatable cuff consisting of a silicone membrane, and an oesophageal drainage system with sump reservoir, connected to 2 drainage channels. The proposed advantages include superior airway seal, reduced pressure on the surrounding tissues, and improved drainage of regurgitated gastric content. We wished to evaluate the performance and safety profile of this novel device. There were no independent clinical trials or any other clinical data available at the inception of the work on our project. We conducted 3 pilot studies on adult female, male and paediatric patients as well as a randomised controlled trial comparing the Baska mask with a single use classical laryngeal mask airway device. We also performed fibreoptic examinations of the behaviour of the Baska mask cuff in situ in anaesthetised adult patients. The Baska mask demonstrated an airway seal superior to that reported for other SADs and comparable overall insertion success rates of 93 - 97%, yet lower first time success rates of 71- 85% and higher device difficulty scores. The significance of the latter is unclear as the experience with this device is limited and the sizing guidelines may be suboptimal. The device safety profile was reassuring in our studies of adult patients. Further work is required to define the device safety profile in children. The fibreoptic examinations demonstrated that the Baska mask cuff is in extensive contact with the mucosa around the laryngeal inlet. This potentially explains the superior airway seal. We conclude that the Baska mask demonstrated promise as an alternative SAD, and is worth of further clinical evaluation. Additional studies are required to define the optimal device sizing guidelines, and to expand our knowledge of the device performance and safety profile.2020-04-0

Applications of Linear Logic to Computation: An Overview

This paper is an overview of existing applications of Linear Logic (LL) to issues of computation. After a substantial introduction to LL, it discusses the implications of LL to functional programming, logic programming, concurrent and object-oriented programming and some other applications of LL, like semantics of negation in LP, non-monotonic issues in AI planning, etc. Although the overview covers pretty much the state-of-the-art in this area, by necessity many of the works are only mentioned and referenced, but not discussed in any considerable detail. The paper does not presuppose any previous exposition to LL, and is addressed more to computer scientists (probably with a theoretical inclination) than to logicians. The paper contains over 140 references, of which some 80 are about applications of LL. 1 Linear Logic Linear Logic (LL) was introduced in 1987 by Girard [62]. From the very beginning it was recognized as relevant to issues of computation (especially concurrency and stat..

A (Not Very Much) Annotated Bibliography on Integrating Object-Oriented and Logic Programming

s (everything from 1989 to 1992), ACM Guide to Computing Literature (1991 and 1992; this is hardly usable as a reference), online databases COMPENDEX (1987-1992) and INSPEC (1988(?)-1992; this is most comprehensive but I had hardly enough access to it). I have also searched Index to Scientific Reviews and got some titles but haven't included them yet. And of course, I have scanned the reference lists of the articles I have read. I have tried to outline the boundaries of subareas in the OOP+LP area and to figure out what is already done and what is still to be done. However the resulting division is imperfect for a number of reasons: ffl it is highly subjective; ffl sometimes a paper falls equally well under two or more divisions; ffl papers which I have not read and which have undescriptive title inevitably are classified wrongly; ffl I have tried not to split related work by the same author or team: all related articles are put in the section which best fits the most important of ..
