Cross T, Navarange R, Son J-H, Burr W, Singh A, Zhang K, Rusu M, Gkoutzis K, Osborne A, Nieuwenhuis Bet al., 2021, Simple RGC: imageJ plugins for counting retinal ganglion cells and determining the transduction efficiency of viral vectors in retinal wholemounts, Journal of Open Research Software, Vol: 9, Pages: 1-14, ISSN: 2049-9647

‘Simple RGC’ consists of a collection of ImageJ plugins to assist researchers investigating retinal ganglion cell (RGC) injury models in addition to helping assess the effectiveness of treatments. The first plugin named ‘RGC Counter’ accurately calculates the total number of RGCs from retinal wholemount images. The second plugin named ‘RGC Transduction’ measures the co-localisation between two channels making it possible to determine the transduction efficiencies of viral vectors and transgene expression levels. The third plugin named ‘RGC Batch’ is a batch image processor to deliver fast analysis of large groups of microscope images. These ImageJ plugins make analysis of RGCs in retinal wholemounts quick, consistent, and less prone to unconscious bias by the investigator. The plugins are freely available from the ImageJ update site https://sites.imagej.net/Sonjoonho/.

Journal article

Gkoutzis K, 2015, Combining Big Metadata with Standarized Ontologies to Identify Unnormalization and Incompatibility among eGovernment Information Systems, 3rd Greek Economic Forum

This proposal supports the premise that the structures of all current eGovernment Information Systems' databases can be exported and treated as Big Metadata which, taking into consideration the existence of standardized ontologies, could allow analysts to identify, and possibly amend, any lack of normalization and compatibility among systems.

Gkoutzis K, 2013, A Semantic Web Based Search Engine with X3D Visualisation of Queries and Results

The Semantic Web project has introduced new techniques for managing information. Data can now be organised more efficiently and in such a way that computers can take advantage of the relationships that characterise the given input to present more relevant output. Semantic Web based search engines can quickly educe exactly what is needed to be found and retrieve it while avoiding information overload.Up until now, search engines have interacted with their users by asking them to look for words and phrases. We propose the creation of a new generation Semantic Web search engine that will offer a visual interface for queries and results. To create such an engine, information input must be viewed not merely as keywords, but as specific concepts and objects which are all part of the same universal system.To make the manipulation of the interconnected visual objects simpler and more natural, 3D graphics are utilised, based on the X3D Web standard, allowing users to semantically synthesise their queries faster and in a more logical way, both for them and the computer.
