Dr. Michalis Mountantonakis is a Postdoctoral Researcher at FORTH
and Laboratory Teaching Staff in Computer Science Department at University of Crete, Greece.
He holds a PhD from the Computer Science Department at
University of Crete (2020), with GPA 9.74/10 (Excellent).
In July 2020, he awarded his PhD thesis with title
Services for Connecting and Integrating Big Number of Linked
Datasets (you can also find the slides and a video here), which was supported by the General Secretariat for Research and Technology (GSRT) and the Hellenic Foundation for
Research and Innovation (HFRI). From the same department, he obtained his MSc in 2016, with GPA 9.87/10 (Excellent),
and his BSc in 2014, with GPA 8.42/10 (2nd in class).
For his dissertation, he won the prestigious
SWSA Distinguished Dissertation Award, which is
given to the PhD dissertation from the previous year with the highest originality, significance, and impact, in the area of Semantic Web! Furthermore,
he awarded the Maria Michael Manasaki legacy's fellowship, which is awarded each year to the best graduate student of Computer Science department of the University of Crete, once a year.
During his undergraduate and postgraduate studies,
he was a research assistant at the Information Systems Laboratory at FORTH-ICS (2013-2020),
where he conducted basic and applied research within the EU-founded research projects PULSE-ART, iMarine and BlueBridge.
His research interests fall in the areas of Large-Scale Semantic Data Integration, Linked Open Data, Semantic Web, LLMs,
and Semantic Data Management. The results of his research have been published in more than 50 research papers including prestigious journals and venues such as ACM VLDB, ISWC, ECML, ACM Computing Surveys, ACM JOCCH and ACM JDIQ.
Finally, he has received several other awards, including a Best Paper Award (Resources Track) in ISWC 2022, and awards in Hackathons and Stelios Orphanoudakis undergraduate fellowship for his BSc studies. Moreover, he was nominated from the Computer Science Department, and he was selected for participating in Roche Continents 2019, where upon review of applications, 100, top-talented science and arts students from european institutes are selected.

LODsyndesis provides several services and
measurements that are useful for several important tasks like (a) object co-reference, (b)
dataset discovery and search, (c) visualization, (d) connectivity assessment and monitoring, (e) production of word embeddings and f) information extraction. In addition, it provides measurements that concern the commonalities of Linked Datasets.
