short bio
Pavlos Fafalios

Welcome to my personal web page!

I am an Assistant Professor of Information Systems at the School of Production Engineering and Management of the Technical University of Crete (Chania, Greece) and Affiliated Researcher at the Centre for Cultural Informatics of the Information Systems Laboratory (ISL) of FORTH - Institute of Computer Science. I obtained my Engineer's Diploma in 2009 from the Department of Information and Communication Systems Engineering of University of the Aegean (Samos, Greece), and my MSc and PhD in 2012 and 2016, respectively, from the Computer Science Department of University of Crete (Heraklion, Greece). I have conducted post-doctoral research at the L3S Research Center of Leibniz University of Hanover (3 years) and the Information Systems Laboratory (ISL) of FORTH-ICS (4.5 years), and I was visiting lecturer for 3.5 years at the Department of Management Science and Technology of the Hellenic Mediterranean University‎ (Agios Nikolaos, Greece).

My research interests fall in the areas of Information Systems and Data and Knowledge Management, with a special focus on interdisciplinary research in these areas and the application of the research findings in different disciplines, including Cultural Heritage and the Humanities. The results of my research have been published in more than 50 refereed research articles, while I regularly participate to the scintific committees of international conferences and journals.

software top
FastCat Catalogues
Web application that supports researchers studying archival material, such as historians, in exploring and quantitatively analysing the data (transcripts) of their archival sources. Developed under my supervision by the undergraduate student Giorgos Rinakakis. More information
ClaimLinker
ClaimLinker is a Web service and API that links arbitrary text to fact-checked claims, offering a novel kind of semantic annotation of unstructured content. The system is based on a scalable, fully unsupervised and modular approach that does not require training or tuning and which can serve high quality results at real time. Developed under my supervision by the undergraduate student Evangelos Maliaroudakis. More information.
SPARQL-LD
SPARQL-LD is an extension of SPARQL 1.1 that enables to directly fetch and query RDF data from heterogeneous sources via SERVICE calls. A distinctive characteristic of SPARQL-LD is that it allows querying and integrating even data in datasets returned by a portion of the query, i.e. identified at query-execution time. More information.
X-Search
X-Search is a web search service that reads the description of an underlying search source, and is able to query that source and analyze in various ways the returned results. X-Search also exploits the availability of semantic repositories. More information.
X-Link
X-Link is a fully configurable, Linked Data-based, named entity extraction tool. X-Link is capable to a) identify entities of interests (e.g. persons, locations, organizations, etc.) in any type of document, b) link the identified entities with semantic resources (i.e. with URIs), c) enrich the identified entities with semantic information (i.e. with properties and related entities), and d) infer whether and how the identified entities are associated. More information.
IOS
IOS (Instant Overview Search) is a search-as-you-type functionality for web searching which provides an overview of the results as the user types his query letter-by-letter. More information.
Theophrastus
Theophrastus is a system that supports the automatic annotation of web documents through entity mining and provides exploration services by exploiting Linked Open Data (LOD), in real-time and only when needed. Theophrastus was awarded the 1st prize in Blue Hackathon 2013. More information.
Ithaca
Ithaca is a tool that reads open datasets, converts their data to RDF triples and loads the derived triples in a Virtuoso warehouse, offering thereby an API for directly exploiting the underlying data. Ithaca was awarded the 1st prize in Hack4Med 2014 (the HOMER project Hackathon). More information.

some personal information top

I was born in Chios, a beautiful island at the east of Greece, just five miles off the Asia Minor coast. In September 2003, I moved a few miles souther to Samos island where I lived five amazing years studying Information and Communication Systems Engineering. In November 2008 I joined the Greek Army Forces for one year to accomplish my military service. In February 2010 I started my graduate studies (MSc, PhD) in Crete island (Heraklion). In June 2016 I moved to Hannover (Lower Saxony, Germany) as a postdoctoral researcer, and in June 2019 I returned to Heraklion and worked at FORTH as a senior researcher. In February 2021, I became a father to Markos, the most wonderful baby boy. In December 2023, I moved to Chania and joined the Technical University of Crete as an assistant professor.

In my free time, I like spending time with my family and friends, watching sports and movies, traveling around, reading books, and taking photos (you can find some here).
