OGD/CKAN Herausforderungen
• Wo suchen? Verteilte nationale und internationale
Datenbestände
• Welche Suchbegriffe verwenden?Uneinheitliche Metadaten und Verschlagwortung,
verschiedene Sprachen und Begrifflichkeiten
• Verschiedene andere Katalogsysteme

Situations in which semantic search
can help
9
I can´t
remember how
to spell the
search term
I can´t
remember
exactly what I
was looking for
I want to gain
background
knowledge to a
certain document
I want to know
more about this
entity in a
certain context.
I want to see facts
from different
sources describing
this entity.
I want to search
in different
languages
simultaneously
I forgot some of
the names for
the entity I´m
looking for
I want the
software to
understand what I
mean by „Jaguar“

Find information faster – Auto-
Complete
10
I can´t
remember how
to spell the
search term
To provide powerful auto-complete also for enterprise search
scenarios you need to establish an enterprise vocabulary.

Reveal hidden information – Status
quo
11
SNCR Search
SNCR OR „Selective non- Search
I forgot some of
the names for
the entity I´m
looking for

Reveal hidden information with
query expansion
12
SNCR SearchOR "selective non catalytic reduction"
SNCR
selective non
catalytic reduction
alternative Label
preferred Label

Reveal hidden information and
relations
14
Find documents
or images related
to any other text.

I want to gain
background
knowledge to a
certain document

Find more specific information with
faceted search
15
facets support
structured queries
facets help
to drill down
search results,
adapt dynamically
Zero-result queries
won´t happen
anymore

energy-related
information about
a country.
