The aim of the project is to offer at the employees, users and researchers tools which will easier the management, search and presentation of the respective material. The aim of the PhD thesis is to present the totality of requirements that the archives’ information systems should apply in order to effectively support the historical research. The requirements have been based on the general rules of the historical research methodology, the practices used by the historians during their research and the studies related to the effectiveness of the several methods of information recovery and visualization in the historical archives. With regard to the historical research methodology, the general rules and the practices that are used by the historians during t...

Σκοπός του έργου είναι ότι θα παρέχει στους χρήστες, εργαζόμενους και ερευνητές στο Ιστορικό Αρχείο, εργαλεία που θα διευκολύνουν την οργάνωση, αναζήτηση και παρουσίαση του υλικού. Σκοπός της διατριβής είναι να παρουσιαστεί ένα σύνολο απαιτήσεων που πρέπει να πληρούν τα πληροφοριακά συστήματα ιστορικών αρχείων προκειμένου να υποβοηθούν αποτελεσματικά την ιστορική έρευνα. Το σύνολο των απαιτήσεων αυτών έχει βασισθεί στους γενικούς κανόνες της μεθοδολογίας της ιστορικής έρευνας, τις πρακτικές που χρησιμοποιούν οι ιστορικοί στην έρευνά τους και στις μελέτες που έχουν γίνει αναφορικά με την αποτελεσματικότητα των διαφόρων μεθόδων ανάκτησης και οπτικοποίησης της πληροφορίας σε ιστορικά αρχεία.

The information in some domains involves entity evolution, a characteristic that introduces additional tasks, such as finding all evolution stages of an entity, and poses additional requirements for the information retrieval process. In this paper, we present a user study aiming to investigate how the different aspects of ontology modelling affect the performance and effectiveness of users regarding information retrieval tasks that are carried out using visualization methods. The results of the user study are analyzed and guidelines for ontology design are offered.

The information in some domains involves entity evolution, a characteristic that introduces additional tasks, such as finding all evolution stages of an entity, and poses additional requirements for the information retrieval process. In this paper we present a user study aiming to investigate the effectiveness of current ontology browsing and visualization methods for supporting users in tasks involving research on entity evolution.

Historic research involves finding, using and correlating information within primary and secondary sources, in order to understand past events. Historians conduct research systematically, by examining past events to renew the past; historic research may involve interpretation to recapture the nuances, personalities, and ideas that have influenced these events, and the expected ...

Leaving university is a complex decision-making process, which is based on different factors that actually forcing a student to drop out from his/her studies. These factors have various effects on the students career path, psychology, on their families, on the educational institutions and the state itself. The aim of this article is to identify the individual characteristics, socioeconomic, academic, emotional and behavioural problems involved in students dropout. A qualitative and quantitative research took place at Malta College of Arts, Science and Technology on data received from the Registrars Office for the period between 2017-2020. The data were based on the number of students who had resigned and they were analysed on year by year rate and also on year and Level rate. The results from the qualitative analysis showed that different external and personal factors contr...
