On the correlation between topic and user behaviour in online communities
(ICWSM-16, 2016-05-20)
In the advancement of a better understanding of user behaviour on the Internet, clustering approaches are used as a means to group and categorise online communities. Although clustering approaches indicate similarity between ...
Tell me who are your friends, and I’ll tell you who you are
(AICS 2016, 2016-09-20)
Mentions of politicians in news articles can reflect politician interactions on their daily activities. In this work, we present a mathematical model to represent such interactions as a graph, and we use it to predict the ...
Identifying equivalent relation paths in knowledge graphs
(Springer Verlag, 2017-06-19)
Relation paths are sequences of relations with inverse that allow for complete exploration of knowledge graphs in a two-way unconstrained manner. They are powerful enough to encode complex relationships between entities ...
SemEval-2016 Task 13: Taxonomy Extraction Evaluation (TExEval-2)
(Insight Centre for Data Analytics, 2016-06-16)
This paper describes the second edition of the shared task on Taxonomy Extraction Evaluation organised as part of SemEval 2016. This task aims to extract hypernym-hyponym relations between a given list of domain-specific ...
Validation of expressive XML keys with XML schema and XQuery
(ACS, 2015)
The eXtensible Markup Language (XML) is the defacto
industry standard for exchanging data on the
Web and elsewhere. While the relational model of
data enjoys a well-accepted definition of a key, several
competing notions ...
SemanTex: semantic text exploration using document links implied by conceptual networks extracted from the texts
(ACMCEUR-WS.org, 2014)
Despite of advances in digital document processing, exploration of implicit relationships

On learnability of constraints from RDF data
(Springer International Publishing, 2016-05-14)
RDF is structured, dynamic, and schemaless data, which enables a big deal of flexibility for Linked Data to be available in an open environment such as the Web. However, for RDF data, flexibility turns out to be the source ...
The finite implication problem for expressive XML keys: Foundations, applications, and performance evaluation
(Springer, 2013)
The increasing popularity of XML for persistent data storage, processing and exchange has triggered the demand for efficient algorithms to manage XML data. Both industry and academia have long since recognized the importance ...
SPORTAL: Searching for Public SPARQL Endpoints
(NUI Galway, 2016-10)
There are hundreds of SPARQL endpoints on the Web, but finding an endpoint relevant to a client s needs is difficult: each endpoint acts like a black box, often without a description of its content. Herein
we briefly ...
