• Research is mainly done with classical search en-
gines for the web (e.g., Google), patents (e.g., DE-
PATISnet
2
(Jürgens and Herrero-Solana, 2015))
or other resources (e.g., research institutes).
• Direct search for innovations is usually not possi-
ble, for instance, due to only partial availability of
solutions. Hence, an extensive search with seem-
ingly fitting keywords is done. Also, incremental
specification of the research is conducted in an ex-
haustive manner.
• Exchanges on the research rarely or never happen,
especially not across several departments. This
proves prior results in the professional search do-
main (Knight and Spink, 2008; Nürnberger et al.,
2015).
• Pre-filtering is usually done by source, institution,
or abstract. This may leave out potentially inter-
esting and relevant documents.
• Patents must be carefully read and evaluated,
while pre-selection is done via fitting, but also
broad, keywords (Lupu et al., 2013).
In order to address these issues, workshop partic-
ipants proposed solutions. Additionally, we deduced
possibilities from the described search processes. To
reduce the effort and time necessary for our further
study, we limited the number of potential solutions to
the ten ideas that the majority of participants empha-
sized. We illustrate these ideas in Table 1.
Table 1: Proposed ideas for supporting research.
P-1 Marking and extracting parts of a document.
P-2 Creating a research history.
P-3 Comparing different search result lists.
P-4 Development of a topic over time (trend analysis).
P-5 Listing important institutions and authors for a topic.
P-6 Filtering documents by domain, country of origin, etc.
P-7 Comparing different versions of the same document.
P-8 Sorting of documents by their topics.
P-9 Referencing documents to other publications.
P-10 Summarizing parts of a document.
Some of these proposals are already implemented
in similar applications. For instance, marking doc-
ument parts (P-1) is possible in most digital readers
and comparing different document versions (P-7) is
part of version control systems to some extend. Also,
many features for filtering, sorting, or similar tasks
are partly supported in reference management sys-
tems (Gilmour and Cobus-Kuo, 2011). However, we
are not aware of an application which combines all
ideas in an integrated system and supports search pro-
cesses as a whole.

To this point, we argue that the most important
ideas have to be identified and defined as require-
ments. Further assessing context information and in-
vestigating potential challenges is necessary. In order
to initiate corresponding research, we conducted user
questionnaires to evaluate the ideas.
2.2 User Questionnaire
During the third step (i.e., Figure 1), we determined
the importance of previously proposed ideas. To this
point, we conducted a user questionnaire with 19 ex-
perts from different sheet-metal working companies
or related research institutes. We asked them to rank
the ideas mentioned in Table 1 from 1 (very impor-
tant) to 10 (not that important). Each priority number
could only be selected once. In addition, the propos-
als could be rated in high, middle and low relevance
(as a complementary ranking) to track whether the
participants understood the system. Furthermore, we
recorded additional ideas, if a participant proposed an
important feature the workshops did not cover.
We did not evaluate five questionnaires, since they
were not completely or wrongly filled out. For exam-
ple, participants described an idea as important but
to have low relevance (the complementary ranking),
which is contradictory, or used the same rank multi-
ple times. We display the results of the remaining 14
responses in Table 2. While we are aware that this
can only be considered an initial sample, we could
still identify the most important ideas from Table 1
that were consistent over almost all questionnaires to
reason our position. For example, summarizing (P-
10) and referencing documents (P-9), as well as list-
ing important authors (P-5) were regularly demanded.
In contrast, the participants considered pre-filtering of
documents (P-6) as least relevant.
Several additional ideas were named, for example
to create a report from result lists, adding information
about addresses of institutions and contact persons, or
to display the relevance of a document to certain top-
ics. During our evaluation, we mapped these ideas
with those we already had. Then, we merged all re-
sults and discussed them with the two experts that ini-
tially helped us. We identified opportunities but also
challenges to support the process of retrieving inno-
vative documents.
3 DISCUSSION
During our study, we found several tasks for innova-
tion research we can support with tools. However,
