PolicyCLOUD
Technical Overview
PolicyCloud has received funding from the European Union’s Horizon 2020 research and innovation
programme under grant agreement No 870675.

Objective
PolicyCLOUD: Analytics-as-a -Service facilitating
efficient data-driven public policy management
02/07/2020 Policy Cloud Data Driven Policies against Radicalisation
policycloud.eu 3
Background
Facts
Increasing use of devices and networks leading to the generation of vast quantities of data
Data linking is becoming the norm (e.g. linking new data sources with established data sources)
Current approaches in policy making are not evidence-based
Mature approaches to analyse and understand the “environment”
Goal
Creation of efficient and effective policies through data-driven policy management
Decision support to authorities for policy modelling, implementation and simulation through
identified populations, as well as for policy enforcement and adaptation
02/07/2020 Policy Cloud Data Driven Policies against Radicalisation
policycloud.eu 4
Main challenges (1/5)
A data-driven approach for effective policies management
Across the complete data path, including data modelling,
representation and interoperability, cleaning, heterogeneous
datasets linking, analytics for knowledge extraction
Exploit the collective knowledge out of policy “collections” combined
with the data from several sources (e.g. sensor readings, online
platforms, etc.)
02/07/2020 Policy Cloud Data Driven Policies against Radicalisation
policycloud.eu 5
Main challenges (2/5)
Compilation, assessment and optimization of multi-domain policies
Holistic policy modelling, making and implementation in different sectors (e.g.
environment, migration, goods and services, etc.), through the analysis and
linking of KPIs of different policies that may be interdependent and inter-
correlated (e.g. environment)
Analysis of (unexpected) patterns and policies relationships
Identification of effective KPIs to be re-used
and non-effective ones (including the causes for not
being effective) towards their improvement
02/07/2020 Kick-off meeting Madrid
policycloud.eu 6
Main challenges (3/5)
Data management techniques across the complete data
path
Meta-interpretation layer for the semantic and syntactic capturing of
data properties and their representation
Data cleaning to ensure data quality and coherence including the
adaptive selection of information sources based on evolving volatility
levels (i.e. changing availability or engagement level of information
sources)
02/07/2020 Policy Cloud Data Driven Policies against Radicalisation
policycloud.eu 7
Main challenges (4/5)
Analytics as a service reusable on top of different datasets
Machine and deep learning techniques (e.g. classification, regression,
clustering and frequent pattern mining) to infer new data and knowledge
Opinion mining, sentiment analysis, social dynamics and behavioral data analytics
Technologies that allow analytics tasks to be decoupled from specific
datasets and thus be triggered as services and applies to various cases
and datasets
02/07/2020 Policy Cloud Data Driven Policies against Radicalisation
policycloud.eu 8
Main challenges (5/5)
Unique endpoint to exploit analytics in different cases
Execution of different models / analytical tools on data (e.g. to identify trends, to mine
opinion artefacts, to explore situational and context awareness information, to identify
sensitives, etc.)
Modelled policies (through their KPIs) realized / implemented and monitored against these
KPIs
Adaptive and incremental visualization enabling the policy lifecycle to be visualized in
different ways, while the visualization can be modified on the fly and can enable the
specification of the assets to be visualized (e.g. data sources or meta-processed information)

Seamless Analytical Framework
Baseline Technology firstly introduced and implemented as Proof-
Of-Concept in H2020 BigDataStack
Collaborative work between IBM and LeanXcale
First prototype already delivered! Its functionality is planned to be
extended in PolicyCLOUD
02/07/2020 Policy Cloud Data Driven Policies against Radicalisation

Seamless Analytical Framework
Modern enterprises use
Operational databases for OLTP load
Key-Value for IoT data
Data warehouses for data analytics
Datalakes
etc ...
Need polyglot capabilities
02/07/2020 Kick-off meeting Madrid

Seamless Analytical Framework
Nowadays: Data Federation using Spark
02/07/2020 Policy Cloud Data Driven Policies against Radicalisation
policycloud.eu 13
Seamless Analytical Framework
Nowadays: Data Federation using Spark
BUT:
Can be very resource consuming
Cannot exploit the specific capabilities of each different datastore
02/07/2020 Policy Cloud Data Driven Policies against Radicalisation
policycloud.eu 14
Seamless Analytical Framework – User Story
Data ingestion in operational datastore (LeanXcale)
Old data becomes historical, with no modifications
Data Warehouse to perform analytics on big data volumes
Distribution of datasets is problematic
Data to be retrieved from both stores
To be merged in the application level
Data consistency considerations when moving datasets
02/07/2020 Policy Cloud Data Driven Policies against Radicalisation
policycloud.eu 15
Seamless Analytical Framework – Solution
Seamless Analytical Framework
Federate data coming from two different datastores:
HTAP Relational LXS Datastore
IBM Object store
sharing the SAME dataset
Single (black box) component that
consists of two datastores
exploits unique characteristics of each one
transparently from the user
does not compromise some requirements for the benefits of others

Policy Cloud Data Driven Policies against Radicalisation - Technical Overview

  • 1. policycloud.eu 1 02/07/2020 Pavlos Kranas (LeanXcale S.L) PolicyCLOUD Technical Overview PolicyCloud has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 870675.
  • 2. policycloud.eu 2 Objective PolicyCLOUD: Analytics-as-a -Service facilitating efficient data-driven public policy management 02/07/2020 Policy Cloud Data Driven Policies against Radicalisation
  • 3. policycloud.eu 3 Background Facts Increasing use of devices and networks leading to the generation of vast quantities of data Data linking is becoming the norm (e.g. linking new data sources with established data sources) Current approaches in policy making are not evidence-based Mature approaches to analyse and understand the “environment” Goal Creation of efficient and effective policies through data-driven policy management Decision support to authorities for policy modelling, implementation and simulation through identified populations, as well as for policy enforcement and adaptation 02/07/2020 Policy Cloud Data Driven Policies against Radicalisation
  • 4. policycloud.eu 4 Main challenges (1/5) A data-driven approach for effective policies management Across the complete data path, including data modelling, representation and interoperability, cleaning, heterogeneous datasets linking, analytics for knowledge extraction Exploit the collective knowledge out of policy “collections” combined with the data from several sources (e.g. sensor readings, online platforms, etc.) 02/07/2020 Policy Cloud Data Driven Policies against Radicalisation
  • 5. policycloud.eu 5 Main challenges (2/5) Compilation, assessment and optimization of multi-domain policies Holistic policy modelling, making and implementation in different sectors (e.g. environment, migration, goods and services, etc.), through the analysis and linking of KPIs of different policies that may be interdependent and inter- correlated (e.g. environment) Analysis of (unexpected) patterns and policies relationships Identification of effective KPIs to be re-used and non-effective ones (including the causes for not being effective) towards their improvement 02/07/2020 Kick-off meeting Madrid
  • 6. policycloud.eu 6 Main challenges (3/5) Data management techniques across the complete data path Meta-interpretation layer for the semantic and syntactic capturing of data properties and their representation Data cleaning to ensure data quality and coherence including the adaptive selection of information sources based on evolving volatility levels (i.e. changing availability or engagement level of information sources) 02/07/2020 Policy Cloud Data Driven Policies against Radicalisation
  • 7. policycloud.eu 7 Main challenges (4/5) Analytics as a service reusable on top of different datasets Machine and deep learning techniques (e.g. classification, regression, clustering and frequent pattern mining) to infer new data and knowledge Opinion mining, sentiment analysis, social dynamics and behavioral data analytics Technologies that allow analytics tasks to be decoupled from specific datasets and thus be triggered as services and applies to various cases and datasets 02/07/2020 Policy Cloud Data Driven Policies against Radicalisation
  • 8. policycloud.eu 8 Main challenges (5/5) Unique endpoint to exploit analytics in different cases Execution of different models / analytical tools on data (e.g. to identify trends, to mine opinion artefacts, to explore situational and context awareness information, to identify sensitives, etc.) Modelled policies (through their KPIs) realized / implemented and monitored against these KPIs Adaptive and incremental visualization enabling the policy lifecycle to be visualized in different ways, while the visualization can be modified on the fly and can enable the specification of the assets to be visualized (e.g. data sources or meta-processed information) 02/07/2020 Policy Cloud Data Driven Policies against Radicalisation
  • 9. policycloud.eu 9 Conceptual architecture 02/07/2020 Policy Cloud Data Driven Policies against Radicalisation
  • 10. policycloud.eu 10 Seamless Analytical Framework Baseline Technology firstly introduced and implemented as Proof- Of-Concept in H2020 BigDataStack Collaborative work between IBM and LeanXcale First prototype already delivered! Its functionality is planned to be extended in PolicyCLOUD 02/07/2020 Policy Cloud Data Driven Policies against Radicalisation
  • 11. policycloud.eu 11 Seamless Analytical Framework Modern enterprises use Operational databases for OLTP load Key-Value for IoT data Data warehouses for data analytics Datalakes etc ... Need polyglot capabilities 02/07/2020 Kick-off meeting Madrid
  • 12. policycloud.eu 12 Seamless Analytical Framework Nowadays: Data Federation using Spark 02/07/2020 Policy Cloud Data Driven Policies against Radicalisation
  • 13. policycloud.eu 13 Seamless Analytical Framework Nowadays: Data Federation using Spark BUT: Can be very resource consuming Cannot exploit the specific capabilities of each different datastore 02/07/2020 Policy Cloud Data Driven Policies against Radicalisation
  • 14. policycloud.eu 14 Seamless Analytical Framework – User Story Data ingestion in operational datastore (LeanXcale) Old data becomes historical, with no modifications Data Warehouse to perform analytics on big data volumes Distribution of datasets is problematic Data to be retrieved from both stores To be merged in the application level Data consistency considerations when moving datasets 02/07/2020 Policy Cloud Data Driven Policies against Radicalisation
  • 15. policycloud.eu 15 Seamless Analytical Framework – Solution Seamless Analytical Framework Federate data coming from two different datastores: HTAP Relational LXS Datastore IBM Object store sharing the SAME dataset Single (black box) component that consists of two datastores exploits unique characteristics of each one transparently from the user does not compromise some requirements for the benefits of others 02/07/2020 Policy Cloud Data Driven Policies against Radicalisation
  • 16. policycloud.eu 16 Query Federation 02/07/2020 Policy Cloud Data Driven Policies against Radicalisation
  • 17. policycloud.eu 17 Data Movement High Level 02/07/2020 Policy Cloud Data Driven Policies against Radicalisation
