Noëmi Aepli – Intern

In UNLP from mar 2012 – sept 2012

I am an intern at Digital Enterprise Research Institute (DERI), National University of Ireland, Galway, working in the Unit for Natural Language Processing (UNLP) under Dr. Paul Buitelaar.

I am an undergraduate student at the University of Zurich, Switzerland, studying Computational Linguistics and Sinology.
Besides my studies I was working for a project at the Institute of Computational Linguistics at the University of Zurich. My responsibility was to analyse German sentences syntactically in order to build a parallel treebank for a hybrid machine translation system.

I am currently working in the MONNET (Multilingual Ontologies for Networked Knowledge) project with the goal to provide standards and technology to facilitate multilingual access to Semantic Web knowledge resources.



Hammad Afzal – Intern

I am working as a Research Internee at DERI under supervision of Paul Buielaar. My work is focused on development of methods for the semi/automatic generation of multilingual lexicons for domain ontologies, exploiting web-based and language resources. The work is being carried out in the context of an ongoing research cooperation with the Delft University of Technology, Karlsruhe University and DFKI on the definition and implementation of ‘lexicalized ontologies’ according to the LexInfo model:

I am originally from University of Manchester, where I have recently (Dec, 2009) finished my PhD. I have been working with Goran Nenadic, based in School of Computer ScienceUniversity of Manchester UK. I am part of GN TEAM, working to automate the process of Semantic Service Descriptions (of Web resources) by applying (existing and newly developed) NLP techniques on the large amount of relevant literature available online (journal papers, conference proceedings, mailing group discussions), aiming to make these resources readily available for discovery. I have also been guided by Dr Robert Stevens during the course of my PhD.

My research during my stay in Manchester

Previously, I have done MSc in Computing Science,from University of Manchester in Sep, 2005. I graduated with BEng Software Engineering from National University of Sciences and Technology NUST, Pakistan in June 2003

Cedric Beuzit – Research Assistant

I am a Research Assistant working for both the NLP unit and the newly-established HCI unit at DERI, since November 2012.

From March to September 2012, I was already doing my master’s degree internship in the NLP unit, and was working on the redesign and the rewrite of Saffron with Dr. Krystian Samp. I am still working mostly on Saffron, especially on HCI issues (browsing experience, visualizations, …) and may also be involved into other side-projects.

From the broad point of view, I am interested in the meaning of things (like words, concepts, contexts, or even the more basic data such as shapes and colours) and building stuffs (that make sense). Being at the cross road between NLP and HCI is then perfect to me, because it is all about grasping how do we understand the world and using those information to design usable usefulnesses.

I studied electronics first, at CFAI Descartes (Montepllier, France) and computer science for robotics at IUT Clermont I (Clermont-Ferrand, France). After a few years of work, I finally got back to college to study computer science and cognitive science at University of Lorraine (Nancy, France) in order to graduate for a Licence ISC (BSc Computer and Cognitive Sciences) and for a Master SCA(MSc Applied Cognitive Science).

I have some work experience as technician (electronics, computer and computer networks), as a technical writer / graphic artist (in the domain of automation), and as a freelance editor for a generalist search engine.

I have some coding experience in ASM, C, Java, Tcl, PHP, BASIC, and my main tools nowadays are Python and Javascript.

Tobias Wunner – Research Assistant

I am a Research Assistant in DERI at the UNLP group led by Paul Buitelaar. My research interests are the use of domain vocabularies in Information Extraction and their lexical enrichment across languages. Finding Semantic Web compliant standards to represent these lexicons, which go beyond the capabilities of SKOS is another challenge.

I studied Computer Science at the University of Ulm, Germany where I did my Diploma Thesis in the Semantic Web Group (under supervision of Dr. Thorsten Liebig and Prof. Dr. Friedrich von Henke). In my thesis (“Enhancing the Relation Extraction Process from Natural Language with Linguistic Enriched Domain Ontologies”) I developed an IE (Information Extraction) system to extract relationships from Natural Language (NL) German News Texts. The prototype was based on a modular architecture using (i) a domain knowledge base with a linked (ii) lexicon. Another aspect of my thesis was how to measure semantic relatedness of different relationships in the domain ontology (e.g. isCEO vs. isHeadOfCompany).

I started my work at DERI in September 2009 working on the LexInfo project. LexInfo is a implementation of the lemon (lexicon model for ontologies) model to generate domain specific lexica from ontology models to enrich them with semantic (graph patterns), terminological (variants/multilingual) and linguistic (morphology/syntax) information.

In 2010 I joined the MONNET (Multilingual Ontologies for Networked Knowledge)  project as a PhD student. The project aims to develop standards to interchange linguistic information on the Semantic Web for Information Extraction and Translation applications. In particular I worked on Cross-Lingual Ontology-Based Information Extraction (CLOBIE) in the financial domain.

In 2012 I joined UNLP as Research Assistant where I am working on Multilingual Semantic Applications within the MONNET project.



Hasti Ziaimatin – Intern

Hasti is currently studying for a PhD in Computer Science at The University of Queensland, Australia under the supervision of Dr. Tudor Groza and Prof. Jane Hunter. Hasti’s PhD thesis is focused on modeling and capturing expertise from fine-grained micro-contributions made to evolving knowledge. In the context of the Skeletome project, a community-driven knowledge curation platform for the Skeletal Dysplasia domain, she will focus on combining ontologies, Linked Data, information retrieval and collaboration aspects to enable novel ways of curating knowledge in the skeletal dysplasia domain. Furthermore, Hasti is interested in acquiring the provenance of knowledge contributed by the community of experts and modeling the expertise of the contributors. In this case, the innovation comes from using fine-grained micro-contributions in the context of living documents for building the expertise profile, rather than whole static documents / publications.
Hasti received her Bachelor of Information Systems from The University of Auckland, New Zealand, with excellent grades and was awarded a senior prize in Information Systems for achieving the best results in advanced computer papers.
