How to capture new insights
by integrating data from
multiple heterogeneous data

d) Data Linking UI
In order to enable batch processing of data,
SMS provides a Google spreadsheet add-on.
This add-on allows users to enrich their data
directly in their spreadsheets.
A set of user interfaces to allow users
create their lenticular lenses –
different views on entity linking.
The RISIS dataset holders all have to describe their
datasets in a detailed, consistent, and uniform way.
To achieve this goal, RDF data model is used to describe
the RISIS datasets. To stimulate non-Semantic Web
users to generate valid RDF metadata descriptions, we
designed a novel user-friendly editor which hides the
complexity of RDF from non-technical users. The metadata
editor exploits the state of the art Web technologies to provide
user-friendly component to view and edit the metadata.
In order to exploit the generated metadata, RISIS datasets
portal brings a user interface to view and browse the
metadata. Faceted browsing allows users to explore the
dataset via multiple entry points, or when users do not
know what they are looking for beforehand. The portal also
handles user registration and supports the process of
reviewing visit/access requests to certain
RISIS datasets.
convert unstructured and structured data to RDF.
expose the functionality of the SMS platform to third-party
users by standard Application Programming Interfaces (APIs).

handle the entity disambiguation
problem and manage the same or
similar entities found in different
datasets.
extract and classify
named entities (e.g.
people, places,
organizations) in
unstructured text.
resolve the mapping
between heterogeneous
classification schemas
(e.g. WoS and FoS, or
different ISO codes for
countries).
allow search on datasets based on
the description of datasets in
multiple metadata categories (e.g.
language, time coverage, etc.).
deal with basic representation of
geographical data together with
geocoding functions and
identifying the boundaries
containing a given point.
provide innovative services based
on new notions of distance (e.g.
traffic congestion, language factor,
flight routes, etc.)
allow integration of data with RISIS public and
private datasets as well as open datasets and social
data available on the Web.

Lenticular Lenses
When comparing two entities,
depending on the user’s
perspective and the context of
study, they might be considered
the same, similar or different.
Sometimes two organizations
(e.g. departments) can be the
same – because they are parts
of the same organization
(university). But if one wants to
compare departments, this is
not the case.
Lenticular lenses support linking
the entities based on the
context of use and provided
features of data.
access and retrieve heterogeneous data.
Access Control Points (ACPs)
- provide standard interfaces to reduce
technical difficulties of accessing data.
- provide a mechanism to coordinate access
to data based on the user role and the
datasets owner’s requirements.

DATA DISCOVERY & COLLECTION
• OpenStreepMap (OSM)
• Database of Global Administrative Areas (GADM)
• Flickr Shapeﬁles Dataset
• Published Shapeﬁles for Individual Countries
• Published Geospatial RDF Datasets

Open Administrative Boundaries
• Level 1: super-national
administrations e.g.
European Union.
• Level 2: country borders
based on the political
entities listed on the ISO
3166 standard.
• Level 3 to 11: subnational
borders such as ``state'',
``province'', ``region'' and
``district''.
• Level 0: countries.
• Level 1 to 5: lower level
subdivisions such as
provinces, departments,
counties, etc.
depending on the size
and availability of data
for the underlying
country.
• Level 1: country
• Level 2: region
• Level 3: county
• Level 4: locality
• Level 5:
neighborhood

DATA LINKAGE
- Query on metadata about the
administrative boundaries
- Find the alignment between levels
in different datasets

DATA LINKAGE
- used the possible mappings between datasets at different levels.
- check the overlaps of areas at the similar level, and for the matching areas apply
string matching to make sure that they refer to the same administrative boundary.
