Docker containers
Docker offers lightweight virtualization
o Containers can be shared/provisioned on different Linux variations/versions
Identical base system
o NOT Required
All BDI components
o Docker containers

BDI Docker Containers (so far)
Data serving: HDFS, Cassandra,
4store, PostGIS, Strabon, Elastic
Search, Hive, Semagrow
Processing: Spark, Flink, Sansa
Stream ingestion middleware:
Flume, Kafka

BDI Instances – An example
Processing and storage components
o Re-used existing docker containers (where available)
o Dockerized by BDE otherwise
o Ensuring all can be provisioned through Docker Swarm
Other BDI Components:
o Support Layer
o Semantic Layer

Semantic Layer
Semantic Data Lakes
o Minimal ingestion
pre-processing
o Semantic layer
maintains metadata
o Add meaning when
retrieving/processing
Data Lake: scalable unstructured data store
Relationship definitions and metadata
JSON-LD CSVW R2RMLXML2RDF
Ongoing Research for Semantic Big Data & Analytics
Knowledge Graphs

Semantic Layer tools
BDE tooling for Semantic Data Lake:
o Swagger: Semantics of RESTful APIs
o Semantic Analytics Stack (SANSA):
Distributed data processing over large-
scale Knowledge Graphs
o Semagrow: SPARQL over Big Data stores
o Ontario: Querying over Semantic Data
Lakes

Demonstrating the Societal Value through 7 Pilot
‘Real-world’ use-cases
BigDataEurope Pilots

Pilots: Overview
SC1: Health & Pharm.
SC2: Food & Agr.
SC3: Energy
SC4: Transport
SC5: Climate
SC6: Social Sciences
SC7: Security

7 Pilots
◎ BDI Platform Instantiations
o Allow end-users to easily deploy functionality in own system environment
o Modularized Docker approach - easier to replace components
o Reduces effort to keep 3rd party software updated & integrated
◎ 7 Societal Challenge Pilots
o Aligned with 7 European Commision H2020 Societal Challenges
o Real-world use-cases (Data, Objectives, Solutions)
o Some pilots have different data & objectives but a similar solution

SC1: Pharmacology research
14-nov.-16
Life
Sciences
& Health
• Query a large
number of datasets,
some large
• Existing elaborate
ingestion and
homogenization by
OpenPHACTS
• Extensive toolset
developed by OPF
and others
Objective: Large-scale heterogeneous pharma-
research data linking & integration

SC1: Architecture & Components
• Replicate Open PHACTS
functionality on the BDE
infrastructure using OS solutions
• Based on Virtuoso, proprietary
distributed database
• Apply to other domains (e.g.
Agriculture)
• Porting to BDI gives flexibility
and enables new functionalities
• Logging & system health monitoring

SC2: Viticulture resources
Food and
Agriculture
Objective: Automate publication ingestion and
thematic classification
• AgInfra is a major
infrastructure for
agriculture
researchers, serving
cross-linked
bibliography, data,
and processing
services

• BDI deployed as an external
infrastructure for processing
text (viticulture publications)
• Storing and processing text at
a larger scale than AgInfra
can currently manage

SC3: Predictive maintenance
Energy
• Wind turbine monitoring
applies computational
models to sensor data
streams
• Models are weekly re-
parameterized using
week’s data from multiple
turbines
Objective: Real-time turbine monitoring stream
processing and analytics

• Existing in-house non-scalable solution for model
parameterization
• Reliable Fortran software for data analysis
• Efficient, but not scalable to data volume
• Developing a BDI orchestrator
• Re-uses existing software unmodified
• Makes it easy to apply in parallel to many
datasets and manage the outputs

SC4: Traffic conditions estimation
Transport
• Combines:
• Traffic modelling from
historical data
• Current measurements from a
taxi fleet of 1200 vehicles
Objective: Estimation of real-time traffic
conditions in Thessaloniki

• New Flink implementations
of map matching and
traffic prediction algorithms
• BDI provides access to
varied data sources
• PostGIS database with
city map
• ElasticSearch database
of historical data
• Kafka stream of real-
time data

SC5: Climate modelling
Climate
• Preparing modelling experiments
• Slicing, transforming, combining datasets
• Submission and retrieval from modelling
infrastructure
• Discovering and re-using previously
computed derivatives
• Lineage annotation: computer derivatives
from datasets and model parameters
• Finding appropriate past runs avoids
repeating weeks-long modelling runs
Objective: Supporting data-intensive climate research

• BDI offers:
• Hive for managing data
in a way that can be
retrieved and
manipulated, rather
than file blocks
• Cassandra stores
structured and textual
metadata for searching
headers and lineage
• Existing infrastructure; stable, reliable software for parallel computation of models
• BDI is deployed as an external infrastructure for preparing and managing datasets

SC6: Municipality budgets
Social
Sciences
• Ingestion of budget and
budget execution data
• Multiple municipalities in
varied formats and data
models
Objective: Homogenized Budgetary data made
available for analysis and comparison

• BDI deployed as ingestion
and storage infrastructure
for external tools
• Homogenizes variety of
data (JSON, CSV, XML,
etc.)
• Exposes data as SPARQL
endpoint serving
homogenized data
• Existing analytics and visualization tools
• Use SPARQL queries to retrieve only the relevant slices of the overall data

SC7: Change detection & verification
Secure
Societies
• Events are extracted from text
published by news agencies and
on social networking sites
• Events are geo-located and
relevant changes are detected by
comparing current and previous
satellite images
Objective: Detect and Verify Events based on Satellite
Imagery, News and Social Media
