text: 'The study explores differences between three user types in the top tweets
about the 2015 “refugee crisis” in Germany and presents the results of a quantitative
content analysis. All tweets with the keyword “Flüchtlinge” posted for a monthlong
period following September 13, 2015, the day Germany decided to implement border
controls, were collected (N = 763,752). The top 2,495 tweets according to number
of retweets were selected for analysis. Differences between news media, public
and private actor tweets in topics, tweet characteristics such as tone and opinion
expression, links, and specific sentiments toward refugees were analyzed. We found
strong differences between the tweets. Public actor tweets were the main source
of positive sentiment toward refugees and the main information source on refugee
support. News media tweets mostly reflected traditional journalistic norms of
impartiality and objectivity, whereas private actor tweets were more diverse in
sentiments toward refugees. '

text: Performance of music in the home was the means by which most works were received
before the advent of audio recordings and broadcasts, yet the notation sources
that form our primary record of this culture have not been the subject of comprehensive
or methodical study. Choices made by arrangers adapting music for domestic consumption
– of instrumentation, abbreviation, or simplification – reflect the musical life
of the 19th century, and can inform our understanding alongside contemporary accounts
such as newspapers, adverts, and diaries. This position paper gives the background,
motivation, and proposed approach of research currently being undertaken within
the Beethoven in the House project. This will include a study of Steiner editions
of Beethoven’s 7th and 8th Symphonies and Wellingtons Sieg, making a detailed
comparison between arrangements, systematically identifying a core common to multiple
versions, and asking if this reflects the stated values of the publisher. A second
survey will look for patterns across a larger sample of lesser-known and poorly
catalogued scores, collating emergent indicators of arrangers’ motivations within
a narrative of the domestic market – the music industry of its day. Both studies
will innovate digital methods which characterise arrangements as music encodings,
including ‘sparse’ approaches to notation and annotation.

text: For musicologists, the collation of multiple sources of the same work is a
frequent task. By comparing different witnesses, they seek to identify variation,
describe dependencies, and ultimately understand the genesis and transmission
of (musical) works. Obviously, the need for such comparison is independent from
the medium in which a musical work is manifested. In computing, comparing files
for difference is a common task, and the well-known Unix utility diff is almost
46 years old. However, diff, like many other such tools, operates on plain text.
While many music encoding formats based on plain text exist, formats used in the
field of Digital Humanities are typically based on XML. There are dedicated algorithms
for comparing XML as well, but they only focus on the syntax of XML, but not the
semantic structures modelled into such standards as MEI. MEI seeks to describe
musical structures, and the XML syntax is just a means to express those structures.
A diff tool for music should focus on comparing musical structures, but not the
specifics of their serialization into a file format. In {Beethovens Werkstatt},
a 16-year project focussed on exploring the concepts and requirements of digital
genetic editions of music, based on and arguing with examples from Ludwig van
Beethoven, a case-bound diff tool for music was developed. The following paper
discusses how that specific tool can be generalized, and which use cases such
a tool may support.

text: The Freischütz Digital project (FreiDi) was one of the pioneer projects employing
MEI in large scale. It did not only try to encode a huge quantity of music material,
it also sought to capture as many aspects of the available sources as possible,
effectively creating data of almost unrivaled richness. This paper discusses the
outcomes of and experiences made in the FreiDi project.

text: With the adoption of RDF across several domains, come growing requirements
pertaining to the completeness and quality of RDF datasets. Currently, this problem
is most commonly addressed by manually devising means of enriching an input dataset.
The few tools that aim at supporting this endeavour usually focus on supporting
the manual definition of enrichment pipelines. In this paper, we present a supervised
learning approach based on a refinement operator for enriching RDF datasets. We
show how we can use exemplary descriptions of enriched resources to generate accurate
enrichment pipelines. We evaluate our approach against eight manually defined
enrichment pipelines and show that our approach can learn accurate pipelines even
when provided with a small number of training examples.

text: The combination of the advantages of widely used relational databases and
semantic technologies has attracted significant research over the past decade.
In particular, mapping languages for the conversion of databases to RDF knowledge
bases have been developed and standardized in the form of R2RML. In this article,
we first review those mapping languages and then devise work towards a unified
formal model for them. Based on this, we present the Sparqlification Mapping Language
(SML), which provides an intuitive way to declare mappings based on SQL VIEWS
and SPARQL construct queries. We show that SML has the same expressivity as R2RML
by enumerating the language features and show the correspondences, and we outline
how one syntax can be converted into the other. A conducted user study for this
paper juxtaposing SML and R2RML provides evidence that SML is a more compact syntax
which is easier to understand and read and thus lowers the barrier to offer SPARQL
access to relational databases.

text: Many of the available RDF datasets describe millions of resources by using
billions of triples. Consequently, millions of links can potentially exist among
such datasets. While parallel implementations of link discovery approaches have
been developed in the past, load balancing approaches for local implementations
of link discovery algorithms have been paid little attention to. In this paper,
we thus present a novel load balancing technique for link discovery on parallel
hardware based on particle-swarm optimization. We combine this approach with the
Orchid algorithm for geo-spatial linking and evaluate it on real and artificial
datasets. Our evaluation suggests that while naïve approaches can be super-linear
on small data sets, our deterministic particle swarm optimization outperforms
both naïve and classical load balancing approaches such as greedy load balancing
on large datasets.
