● Ground: SPARQL endpoints
● Patients: RDF-hungry people
● Symptoms: paralysis (can’t write!), syntax errors,
schema mismatch, empty results
➔ FRUSTRATION and HUNGER !
● Diagnostic: SPARQL queries are toxic to humans
●
Treatment: use SparklisSparklis to avoid direct contact
composition: natural language, full guidance, expressive

Semantic mining of respiratory health knowledge from
scientific literature and clinical guidelines
Sergio Consoli, Xiao Ming Zhou, Wei-Shun Bao, Declan P. Kelly, Vincent Lou
Philips Research: [name.surname]@philips.com
• Application of NLP, data mining, and advanced text analytics into advanced AI systems for semantically mining
information from scientific literature and clinical guidelines to extract new knowledge on the respiratory health domain
• Curated repository of selected medical documents into knowledge-base in respiratory health
• Goal  feeding and controlling connected respiratory health devices according the gathered knowledge and providing
intuitive visualization interfaces for user understanding
Scope 1: data bootstrap via scientific literatures to extract knowledge
Scope 2: provide relevant
feedback and insights from data
Challenges
• Repository of biomedical scientific literature
– Large volume & Accessibility
• Data Processing and Interpretation
– Performance VS Speed
• Knowledgebase
– Data-linking of concepts and relationships to ensure both syntactic and semantic interoperability
• Information Querying and Retrieval
– ML & prediction models for deriving rules and facts, and providing feedbacks/insights/recommendations

Prototype:Open Data Mashups for Data Journalism (ODMOJO):
PRESS: A Publication REpository Semantic System
• PRESS is an open-source publication system that exploits semantic
technologies, in order to cover the needs of both individuals and
organizations
• Fast data entry, user-based repository
• Advanced query capabilities
• Integration with other systems
• Commercial: designed mainly for experts, not extensible
• Existing open-source: difficulty in expressing complex queries, rely on rigid relational schemas

Vision and market gap
• Motivation
– Comments are becoming an integral part
of the Web, and not only the Social Web
– Yet, comment management is largely ad-
hoc and inefficient
• Grand vision: interconnect, search,
store, retrieve, evaluate comments that
exist on the Web
Methinks
Methinks Application
• Advantages for consumers/end-users
– Become well-informed in just a glance
– Quickly identify non-standard information that can be
found only in comments
– Browse based on arguments, not on words
• Advantages for analysts (admins)
– A cheap way to integrate fancy, comment-related
functionality in one’s web site
– A measurable way to extract conclusions (analytics) in
online discussions

Introduction
DALICC stands for Data Licenses Clearance Center. The
project‘s aim is to develop a software framework that
significantly reduces the costs of license clearance in the
creation of derivative (data) works.
DALICC follows a deontic approach to express machine-
readable permissions, prohibitions and duties defined in a
license. DALICC utilizes the ODRL 2.0 ontology in
combination with CCRel. Additionally DALICC utilizes an
extended set of properties that are necessary to capture the
full semantic spectrum of legal expressions defined in a
license text.
By doing so DALICC allows to represent property rights
policies in a legally valid and machine-processable way.

(BMVIT) under the program "ICT of the Future" between November 2016 - October 2018. More information

DALICC Vocabulary – REL Extension
The DALICC vocabulary extensions evolved from an in depth
analysis of 15 standard licenses (including CC, APACHE, BSD,
GPL MIT) under the supervision of legal experts. The following
expressions need to be added to cover the full semantic
spectrum of copyright statements:
PROPERTIES AFFECTING THE ASSET PROPERTIES AFFECTING THE LICENCE
dalicc:charge dalicc:addStatement
dalicc:sublicense dalicc:attributionNotice
dalicc:promote dalicc:attachOffer
dalicc:publish dalicc:chargeOffer
dalicc:irrevocable
dalicc:modificationNotice
dalicc:noWarrantyNotice
dalicc:patentFree
dalicc:patentNotice
dalicc:perpetual
dalicc:royaltyFree
dalicc:worldwide
The examples illustrate the RDF/Turle syntax of BSD 3.0, CC-BY
and APACHE using the DALICC properties (bold).

Future Work
The DALICC Framework will consist of four components:
• License Composer: Lets you create customized licenses
• License Library: Lets you choose from a set of standard licenses
• License Annotator: Provides you with a machine-readable and human-readable version of
your license
• License Negotiator: Checks compatibility, detects conflicts and supports conflict resolution

    Introduction DALICC stands forData Licenses Clearance Center. The project‘s aim is to develop a software framework that significantly reduces the costs of license clearance in the creation of derivative (data) works. DALICC follows a deontic approach to express machine- readable permissions, prohibitions and duties defined in a license. DALICC utilizes the ODRL 2.0 ontology in combination with CCRel. Additionally DALICC utilizes an extended set of properties that are necessary to capture the full semantic spectrum of legal expressions defined in a license text. By doing so DALICC allows to represent property rights policies in a legally valid and machine-processable way. Partners: • UAS St. Pölten (Lead) – Tassilo Pellegrini, Andrea Schönhofer, Peter Judmaier, Stefanie Größbacher • Vienna University of Economics & Business – Simon Steyskal, Sabrina Kirrane, Axel Polleres • University of Innsbruck – Oleksandra Panasiuk, Anna Fensel • Höhne, In der Maur & Partner Rechtsanwälte OG – Markus Dörfler • Semantic Web Company GmbH – Thomas Thurner, Victor Mireles-Chavez, Kurt Moser Contact: www.dalicc.net Acknowledgment: DALICC is funded by the Austrian Federal Ministry of Transport, Innovation and Technology (BMVIT) under the program "ICT of the Future" between November 2016 - October 2018. More information https://iktderzukunft.at/en/ DALICC Vocabulary – REL Extension The DALICC vocabulary extensions evolved from an in depth analysis of 15 standard licenses (including CC, APACHE, BSD, GPL MIT) under the supervision of legal experts. The following expressions need to be added to cover the full semantic spectrum of copyright statements: PROPERTIES AFFECTING THE ASSET PROPERTIES AFFECTING THE LICENCE dalicc:charge dalicc:addStatement dalicc:sublicense dalicc:attributionNotice dalicc:promote dalicc:attachOffer dalicc:publish dalicc:chargeOffer dalicc:irrevocable dalicc:modificationNotice dalicc:noWarrantyNotice dalicc:patentFree dalicc:patentNotice dalicc:perpetual dalicc:royaltyFree dalicc:worldwide The examples illustrate the RDF/Turle syntax of BSD 3.0, CC-BY and APACHE using the DALICC properties (bold).
