Adaptive task assignment in spatial crowdsourcing
(2016-08)Spatial crowdsourcing has emerged as a new paradigm for solving difficult problems in the physical world. It engages a large number of human workers in scenarios such as crisis management and smart cities. The utility of ... -
Categorising the online communities of stack exchange using quantitative user behaviour features
(Insight Centre for Data Analytics, NUI Galway, 2016-03-02)Maintaining online communities is vital in order to increase and retain their economic and social value. Before applying any performance altering strategies, it is important to determine the different types of communities, ... -
Classifying sentential modality in legal language: A use case in financial regulations, acts and directives
(ACM, 2017-06-12)Texts expressed in legal language are often di cult and time consuming for lawyers to read through, particularly for the purpose of identifying relevant deontic modalities (obligations, prohibitions and permissions). ... -
Combining lexical and spatial knowledge to predict spatial relations between objects in images
(ACL Anthology, 2016-08-11)Explicit representations of images are useful for linguistic applications related to images. We design a representation based on first-order models that capture the objects present in an image as well as their spatial ... -
Distributed dataflow processing of large RDF graphs
(2017-05-29)As part of the big data world, RDF, the graph-based data model of the Semantic Web, is growing in use. Consequently, the size of available RDF data is increasing and massive datasets are becoming commonplace. Nevertheless, ... -
DRETa: extracting RDF from wikitables
(CEUR-WS.org, 2013)Tables are widely used in Wikipedia articles to display relational information - they are inherently concise and information rich. However, aside from info-boxe s, there are no automatic methods to exploit the integrated ... -
The duality of e-participation - a model and technical infrastructure to study and harness social media-based participation
(2016-10-21)Despite the proliferation of e-Participation initiatives, overall efforts towards mainstreaming social media-based and citizen-led political deliberations are still limited. Consequently, there is a paucity of research on ... -
Dublin City University and Partners' participation in the INS and VTT Tracks at TRECVid 2016
(2016-11-14)Dublin City University participated with a consortium of colleagues from NUI Galway and Universitat Polit`ecnica de Catalunya in two tasks in TRECVid 2016, Instance Search (INS) and Video to Text (VTT). For the INS task ... -
Enabling case-based reasoning on the web of data
(2010-07-20)While Case-based reasoning (CBR) has successfully been deployed on the Web, its data models are typically inconsistent with existing information infrastructure and standards. In this paper, we examine how CBR can operate ... -
Evaluating and benchmarking the performance of federated SPARQL endpoints and their partitioning using selected metrics and specific query types
(2017-02-07)The increasing amount of Linked Data and its inherent distributed nature have created for need to developing and researching querying technologies. Inspired by research results from traditional distributed databases, ... -
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 ... -
A hybrid method for rating prediction using linked data features and text reviews
(CEUR-WS.org, 2016)This paper describes our entry for the Linked Data Mining Challenge 2016, which poses the problem of classifying music albums as good or bad by mining Linked Data. The original labels are assigned according to aggregated ... -
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 ... -

Knowledge base completion using distinct subgraph paths
(ACM, 2018-04-09)Graph feature models facilitate efficient and interpretable predictions of missing links in knowledge bases with network structure (i.e. knowledge graphs). However, existing graph feature models-e.g. Subgraph Feature ... -
Learning content patterns from linked data
(CEUR-WS.org, 2014)Linked Data (LD) datasets (e.g., DBpedia, Freebase) are used in many knowledge extraction tasks due to the high variety of domains they cover. Unfortunately, many of these datasets do not provide a description for their ... -
Leveraging Wikipedia-based features for entity relatedness and recommendation
(2018-01-31)Entities such as people, locations, organizations play a key role in natural language understanding. Most of the approaches that deal with natural language processing tasks, require a method to measure the relatedness ... -
