The document discusses how semantic technologies can help make customer support systems more intelligent by understanding customer needs better. It proposes using a knowledge model and controlled vocabulary to translate between technical terms used by suppliers and plain language used by customers. This helps provide a more user-friendly digital guidance system within the customer support system. The approach results in a semantic index of content, improved search and recommendation capabilities, and the ability to combine information from multiple knowledge bases automatically.

Addressed problem
Customer support systems frequently cause
disorientation due to the technical terms used and a
lack of transparent and easily comprehensible
navigation structures. Providers of products and
services from various sectors (telecommunications,
public administration, law, etc.) use different
languages and differing categories than consumers
(or citizens) do. Thus, in many cases clients have
to deal with frustrating translation work which leads
to misunderstandings and increasing costs in the

Addressed problem
Working as an analyst, researcher, product
manager or as a journalist means that one has to
skim through hundreds of news articles per day. On
the one hand the usage of social networks and
attached reputation systems can help to narrow
down the number of relevant sources, on the other
hand an ever increasing amount of information has
ended up on our desktops since we have become
active members of Twitter, Linkedin or other social
media channels. Unstructured information makes
up the largest portion of frequently quoted 'big
data'. Being able to deal with unstructured
information in combination with structured data like
statistics or relational databases has become a key
ability to succeed in a variety of knowledge
intensive industries.

full potential the underlying index has to be built
upon a specific knowledge model. A vertical search
engine, as distinct from a general search tool,
makes also use of an individual user interface and
domain-specific navigational elements. But most

clearly defined scope, the use of semantic
knowledge models achieves a very good cost-
benefit ratio.

Our solution approach
In order to make specific knowledge about
business processes, methods or technologies
available for as many employees as possible, we
combine the best of three worlds: enterprise
collaboration software, text mining and controlled
vocabularies. This results in solutions which fulfill
the demand for highly dynamic and flexible
knowledge bases, still stable (technical and
content-wise) enough to be used in professional
environments. Since the knowledge base is
generated around a controlled vocabulary acting as
a meta-layer, traditional navigation structures like
trees no longer act as a rigid corset which makes
traversing of graph-like structures impossible.

high degree of reusability and linking.
Our solution approach
The strict usage of semantic web standards, not
only as an export format but as the way to
represent data internally allows us to bring linked
data to its full potential. Initial phases of a
knowledge graph project might start with the
creation of a SKOS thesaurus further enriched by
facts or ontological statements from other linked
data sources. The publication of linked data inside
corporate boundaries or of linked open data on the
(semantic) web is technically spoken the same
task. In both cases data can be accessed

management systems are still more focussed on
workflow management or archiving solutions than
on functionalities which help to put content into the
context of the actual work step.
Our solution approach
Recommender engines work on top of semantic
fingerprints. Each business object (resource) is
represented by its semantic metadata which is a
fragment of the overall enterprise knowledge graph.
This meta information is used to detect hidden links
between objects like persons or documents.
Controlled vocabularies based on SKOS and linked
data build the backbone to express the semantic
fingerprint of each resource. Algorithms which
calculate the 'similarity' between such graph
fragments are used as core elements for the
recommendation engine.

• Large scale triple stores (e.g.: Virtuoso) Search has become a more and more important

systems. Learning from web search engines, most
intranet searches have already introduced some
useful assistance functions like auto-complete.
Semantic search can go far beyond those rather
simple features and can help to reduce search
times to a minimum while user experience will
improve noticeably. Looking at digital assistants like
Apple's Siri, it becomes obvious that the role of
search systems will become more and more
important for the next generations of knowledge
bases. Semantic search and search in general is
still very focused on the idea of retrieving a list of
relevant documents whilst in reality knowledge
workers have to find and link information from a
huge variety of sources including statistical
databases, videos or personnel databases.
Our solution approach
Semantic search in the context of linked data
means to search over a knowledge graph including
document search. This approach makes complex
queries possible, e.g.: show me all business news
