CARREAR SUMMARY:
Prof. Dr. Vidal is a full professor at Universidad Simón Bolívar (USB), Caracas, Venezuela where she leads the
Semantic Web group, teaches undergraduate and graduate courses in Databases, Logic, and Semantic Web, and has
advised the theses of eight doctoral students, twelve masters, and more than 100 undergraduate students. Areas of
research go from selecting and modeling web sources, query rewriting, query processing, graph data management,
and pattern and link discovery; further, she has addressed the problem of benchmarking of query processing tasks.
Prof. Dr. Vidal has been Dean Assistant for Research in Applied Sciences and Engineering, USB (Sept 2011-2014)
and was the Director of The Faculty Development Direction USB March-Sept 2011. She has been awarded with the
Best Teacher Award of USB (Associate Professor Category 2000-2001 and Full-Professor Category 2011-2012);
additionally, she received the Best Faculty Award Procter&Gamble Venezuela on 2004.
She has applied and extended results from Databases, Graph Theory, and Artificial Intelligence to address data
management problems in emerging infrastructures, e.g., Web sources, services, RDF datasets. Further, her proposed
techniques have been implemented in computational tools that are available to the community, and that have become
required references for benchmarking semantic-based data management engines, e.g., ANAPSID, MCD-SAT.
Results of her studies have been reported as publications in the most prestigious journals and conferences of the
Semantic Web (SWJ, ISWC, ESWC), Artificial Intelligence (AAAI, K-CAP), Databases (SIGMOD, EDBT, ICDE,
TLDKS), and Bioinformatics (Database: The Journal of Biological Databases and Curation, JBCB, ACM-BCB, SSDBM,
IEEE-EMBC, DILS, IEEE CIBCB). She is part of the editorial board of the Journal of Web Semantics, Video Journal of
Web Semantics, and the ACM Journal on Data and Information Quality; additionally, she is a regular reviewer of first

2013-2014), Session chair (ISWC, ESWC, DILS, Mobile), panelist (ESWC 2014) in international conferences, Tutor
and Accompanying Professor, OTM Academy 2009-2015), summer schools (SSSW2015), and has co-chaired doctoral
consortiums (OTM Academy 2014-2015, ISWC 2015).
Currently, Prof. Dr. Vidal is focusing on: data management problems in non-traditional data providers, e.g., crowdsource or linked data; usage of semantics to determine relatedness, and discovery patterns and associations in
knowledge graphs; and graph techniques to exploit semantics encoded in large graphs data management.
Prof. Doctor Vidal has been a visiting professor at U. Maryland, U. Politécnica de Madrid, U. Politécnica de Cataluña,
Karlsruhe Institute of Technology, and U. Nantes.

and Resource Retrieval in the Semantic Web, in conjunction with ISWC 2009, and OnTheMove Academic (OTMa)
2014. Further, she has been the invited speaker of International Workshop on Services and Applications over Linked
APIs and Data (SALAD 2015) colocated with ESWC 2015.
Prof. Dr. Vidal has collaborated in three EU and more than 10 NSF founded projects, and one France-Venezuela
(FONACIT-CNRS); additionally, she has been PI of three projects founded by AECI. She has developed an
international scientific network of collaboration.
Prof. Dr. Vidal has participated in research and development projects for data integration and management in Latin
American Organizations for more than 10 years.
Finally, during her studies, Prof. Dr. Vidal has received Honors in her master thesis (August 1991) and doctoral
dissertation (January 2000), and the award of the Excellent Graduate Student from the Fundación Gran Mariscal de
Ayacucho on 1991. Additionally, Prof. Dr. Vidal received a research fellowship from the CONICIT (National Council for
Research and Technology of Venezuela, 1995-1999). During her Ph.D. work, Prof. Dr. Vidal worked under the advise
of Prof. Louiqa Raschid at the University of Maryland, USA (1995-1999); she proposed query planning and execution
techniques for Web Sources with limited query capabilities. Results of this work were published on five international
conference papers and two journal papers.

Current Research Projects
1. Query processing and Data Management on Knowledge Graphs: The goal of the project is to
develop query processing and data management techniques in knowledge graph data providers:
Crowd-source or Linked Data Fragments. Novel adaptive query processing techniques that exploit
the Linked Data technologies are developed in collaboration with Maribel Acosta from Karlsruhe
Institute of Technology. These techniques are developed in the context of ANAPSID
(https://github.com/anapsid/anapsid) and GRAPHIUM (http://graphium.ldc.usb.ve/). Results have
been published in ESWC2010, ISWC2011, ODBASE2011, ISWC2012, and AMW2015.
Furthermore, the problem of source selection and query rewriting is tackled in collaboration with
Prof. Dr. Blai Bonet at the U. Simón Bolívar, and solutions supported on Propositional Logic and
SAT solvers’ technologies are exploited to efficiently enumerate the space of query rewritings. The
computational tools MCDSAT and SSDSAT implement these techniques and are publicly available;
results have been published at AAAI 2006, ISWC 2010. Further, in collaboration with Prof. Pascal
Molli and his research team at U. of Nantes, query rewriting techniques have been extended for
SPARQL queries and views; results of this work has been accepted at DEXA 2013 and in the
journal of TLSDK2015. Future plans are to develop in conjunction with Prof. Dr. Pascal Molli’s
research team, novel data management techniques for duplicated and replicated RDF data will be
developed.
2. Data mining techniques for Knowledge Graphs: The goal of this project is to develop prediction
techniques that allow for determining relatedness between entities in a knowledge graph, as well
for the discovery of hidden patterns and associations between these entities. The proposed
techniques rely on graph theory solutions and similarity measures, and have been applied in the
context of the Biomedical domain to discover portions of drug-target knowledge graphs that
comprise potentially novel drug-target interaction. This project is conducted in collaboration with
Prof. Dr. Louiqa Raschid from the University of Maryland. Results have been published at SIGMOD
2012, ACM BCB 2013, the Semantic Web Journal 2014, ISWC 2014, AMW2015, and Database:
The Journal of Biological Databases and Curation 2015. Demonstrations of the developed
techniques have been presented at ISWC 2012. The developed graph-mining techniques
developed in collaboration Prof. Dr. Louiqa Raschid at the University of Maryland will be applied to
detect patterns from clinical records that suggest drug-induced liver injury and allow the
understanding of liver toxicity.
3. Query ranking techniques for Knowledge Graphs: The goal is to define query ranking
techniques to execute user multi-objective query against large knowledge graphs; this work is
conducted with the collaboration of Prof. Dr. Marlene Goncalves from U. Simón Bolívar. Results
have been published in DEXA 2005, 2009, and 2013, two book chapters, and three journals.
Applicability of these techniques has been shown in different domains: rank geographical regions
based on climatological multi-dimensional, and to identify administrative divisions/locations where a
given political party has the highest chances of win an election. Initial results have been published
and demonstrated in ISWC 2011, ODBASE 2011, OTM 2012, and 2013; further, one book chapter
was published showing the results of these techniques in the political domain. The publicly
available tool Fragola (http://fragola.ldc.usb.ve/) illustrates the main features of the ranking
techniques.
4. Graph data management for Knowledge Graphs: The goal is to define data management
techniques for large graphs. Results from Graph Theory and Graph Logic will be exploited to define
a formal framework that relies on graph invariants, navigational strategies, and optimization
problems, to scale up data management to large and updatable Knowledge graphs. Initial results
have been problished in COLD 2013 and AMW 2015.A tool named Graphium
(http://graphium.ldc.usb.ve/) is publicly available and has been demonstrated at ISWC 2013 and
ESWC 2014. Further, Graphium has been used in the hands-on of the tutorial: “Semantic Data
Management in Graph Databases” in ESWC 2014.
