USEWOD '15 and PROFILES '15
Preface
This joint volume of proceedings gathers together papers from the 5th
International Workshop on Using the Web in the Age of Data (USEWOD '15) and the
2nd International Workshop on Dataset PROFIling and fEderated Search for Linked
Data (PROFILES '15), held on the 31st of May and the 1st June respectively during
the 12th European Semantic Web Conference (ESWC) in Portorož, Slovenia.
People argue that we have moved into an age of several Webs - the Web of
Data, the Web of Documents, the Semantic Web, the Deep Web, the Dark Web, and
many more. However, this is an illusion - there exists only the one #WebWeHave,
and it is under our control to make it be the #WebWeWant. To emphasize this, the
key theme of the 5th edition of the USEWOD workshop is about using the Web in the
age of data, bringing together two spaces again that have recently been investigated
separately: classical Web usage mining and Web usage mining in the context of the
Web of Data.
The purpose of the USEWOD workshop series has been to create and
maintain a forum for researchers to investigate the synergy between the Web of Data
and Web usage mining. This required the analysis of semantic data usage. With the
current edition, we respond to the fact that publishing and consuming raw data on the
Web is an established paradigm today and turn the USEWOD workshop into a forum
to discuss more general questions about the usage of the Web. How will the analysis
of Web usage benefit from the possibility to blend the classical log with the structure
sourcing from Linked Data? Can the progress that has been made on (Read/Write)
Linked Data change the way we interact with the Web and what does that mean for
the usage analysis capabilities we have at hand today?
In line with this focus, this year’s USEWOD is dominated by position
contributions designed to stimulate discussion. We extended the standard paper
track by a blog on the #WebWeWant and its relationship to the interface between
classical-format and Linked Data. The blog was open as well as moderated and
quality-controlled through internal reviewing. In addition to a regular, peer-reviewed
paper and an invited paper, these proceedings also include the position contributions
published on our blog and website.
While the Web of Data, and in particular Linked Data, has seen tremendous
growth over the past years, take-up, usage and reuse of data are still limited and is
often focused on well-known reference datasets. As the Linked Open Data (LOD)
Cloud includes data from a variety of domains spread across hundreds of datasets
containing billions of entities and facts and is constantly evolving, manual
assessment of dataset features is not feasible or sustainable, leading to brief and
often outdated dataset metadata. Given the dynamic nature of the LOD Cloud,
particular focus should be on the development of scalable automated approaches,
which facilitate the frequent assessment and profiling of large-scale datasets to
enable the selection of suitable datasets for query federation and, more generally,
dataset recommendation for specific applications.
The PROFILES '15 workshop is a continuation of the workshop series
successfully started as PROFILES '14 at ESWC 2014. These workshops aim to
gather innovative query and search approaches for large-scale, distributed and
heterogeneous linked datasets in line with dedicated approaches to analyse,
describe and discover endpoints, as an inherent task of query distribution and
dataset recommendation. The PROFILES '15 workshop aims to become a highly
interactive research forum for researchers. PROFILES '15 brings together
researchers and practitioners in the fields of Semantic Web and Linked Data,
Databases, Semantic Search, Text Mining, NLP as well as Information Retrieval.
PROFILES '15 gathered novel works from the fields of semantic query interpretation
and federated search for Linked Data, dataset selection and discovery as well as
automated profiling of datasets using scalable data assessment and profiling
techniques.
We would like to take this opportunity to sincerely thank the authors for their
invaluable and inspiring contributions to the workshops. Our sincere thanks are due
to the program committee members for reviewing the submissions and assuring the
good quality of the workshop program. We are also very grateful to the organisers of
the ESWC 2015 conference for their support in the workshop organisation. Great
appreciation of his time and expertise goes to PROFILES keynote speaker Heiko
Paulheim from the University of Mannheim, Germany, for his talk entitled “What the
Adoption of schema.org Tells Us About Linked Open Data”.
