The main focus of Science Demonstrator sessions is to provide feedback to the EOSC community on the first experience of science demonstrators in the practical use of the emerging EOSC ecosystem. Each panel will consist of a representative of a Science Demonstrator that will provide an overview of their experiences in the use of emerging EOSC services. These sessions will help members of the scientific communities understanding the current state of maturity of the EOSC ecosystem and what is obtainable in a field of scientific research. It is also valuable to prospective Service Providers who wish to discover what are the challenges and opportunities that user communities might have to deal with, as a result of the adoption of their services. This session will focus on Social and Earth Sciences.

• Create a text mining tool to identify named entities in
archaeological reports (text files)
• The entities broadly answer to “What-Where-When”
questions according to the domain ontology CIDOC CRM
• Identified entities enrich the document metadata and
enable finding it and linking it to other related datasets
• The result is of paramount importance as most of the
documentation in archaeology and in cultural heritage is
textual

• For the Science Demonstrator, we planned to work on
texts in Italian, as similar work had been done for English
and Dutch (but not in a cloud framework)
• Success rate should reach at least 90%
• Domain vocabularies are paramount for the work, so a
revision of the available ones was also planned
• Linguistic services also needed; they were already available
• GATE (Stanford)
- Word Segmentation
- Part of Speech recognition and tagging (POS)
• OpenNER (CNR-ILC)
- Named Entities Recognition and resolution

• The work was completed and is working very well
• The required services were all made available and working
• The tool is now being tested on further sets of textual
documents
• It is planned to incorporate it in the ARIADNEplus cloud
services, making it multingual

Apart from issues specific to the service (vocabulary
availability, stemmers, etc.) the main issues concerned the
following:
• Cumbersome AAI
• The user interface that needed to adapt to the one already
available to access the cloud. This includes choosing the
data to be processed and getting the results.
Both the above will be addressed in the ARIADNEplus project

739563
Apart from improving the efficiency of the service (which is
already in the plans) to achieve the necessary scalability, the
necessary changes concern:
• Making its use easier in the cloud
• As regards the EOSC ecosystem, it must be (created? and)
adapted to the researchers’ needs rather than to an a-
priori architecture. This requires a substantial effort, which
is perhaps underestimated, and the researchers’
participation in it.

Digital representation with visual media is of paramount
importance for Cultural Heritage (CH) research
Goals of Visual Media Service:
• Easy publication on the web to share with peers and the
public, one-click approach, managing different types of
data (2D hi-res images, RTI, 3D models)
• Availability of customizable visualization tools
• Permanent repository space, search&retrieval features
• All code is open source

• Support for users’ authentication (D4Science, Google)
• Implementation of several extensions (data management,
visualization tools and configurability)
• Integration with VRE (D4Science)
• Evaluation of resources usage and possible bottlenecks
(after user study)  possibly, endorse parallelization and

We are near completion of our SD:
• Users authentication integrated in the VisMediaService
• Several updates and extensions introduced in the
VisMediaService
• User testing started on October:
• Large number of visual files uploaded in the system by users
• Early evaluation of user satisfaction is largely positive
• Users’ appreciation for the new features and for the integration
with the VRE (D4Science)

No major issue to report
Understanding how to include EOSC features/support was quite easy,
thanks to the good documentation and easy contact with the developers
(by the way, some of them staff of our same CNR Institute)
Good support of shepards
Not easy to understand the overall framework of the EOSC project for
newcomers
Remaining issues:
• Evaluate the performances of the system under pressure (large no. of
contemporary users, both at data upload & interactive visualization
time)
• The latter is planned at start-up of the new EC Infra “ARIADNE+”
(providing a very large community of CH users) – early 2019

What are the main things you would change in your science
demonstrator?
● Plan the user test and verification earlier in the time planning
(giving less emphasis to the implementation of new features)
● Also to have sufficient time to evaluate performances needs and
consequent EOSC solutions
What are the main things you would change in the EOSC
ecosystem?
• Provide a structured and complete introduction and training of
newcomers (e.g. SD proponents which are not EOSC partners), to
support a faster start-up and a better understanding of the
project resources and who-is-who. One week course (with written
material)?
• Define a reward program/policy for people providing open data

● A single scientific repository is of limited value
● Real benefits come from ability to exchange data
within a network
● Current technology for exchanging data across
repositories (OAI-PMH) more than 15 years old
○ Scalability
○ Implementations inconsistency
○ Metadata synchronisation only

Enhancing the services of the VERCE portal and integrate the EGI
FedCloud Infrastructure as the main data-intensive computational
service provider for Misfit Analysis Workflows.
These consists in three different phases:
- Assisted discovery & preprocessing of the observed data and
the correspondent synthetic results
- Data pre-staging from the FDSN network to an iRODS instance
with metadata and provenance
- Final comparison adopting different Misfit techniques.
AAI and delegation mechanisms are needed to submit executions
and to connect to remote data-stores (iRODS) from the Cloud

● Not much technological guidance: Choice left to communities, e.g.
Cloud-ready workflow system, key/value store, queueing,
scheduling, interoperability, Storage
● Inherited legacy codebase and components (gUSE, GridFTP, Globus)
● Federated Authentication was still subject to change during Pilot
(RCauth SLC service not yet working)
● No built-in credential delegation e.g. proxy certificate delegation
● Differences in network implementations on FedCloud sites (required
floating IP requests on some sites, not implemented by middleware
at the time)
● Virtual Appliances needed to be upgraded (was done in SD and
committed back upstream to EGI AppDB)

739563
● Give more weight to sustainability when choosing tools and
services
● Prefer simplicity in customization and adaptation, e.g. scripted
solutions / plugin mechanisms
● Adapt to external services instead of self-hosting if in doubt
● EOSC could “feature” software and tools, promoting them to
the communities with enough description about usage and
transparency in its sustainability plans.
● The reproducibility problem should start to be addressed
structurally, scaling from ad-hoc solutions to reusable and
more general services. Computational tools offered by EOSC
should be aware of the existence of these service and use
them.
