This particular type of communication differs from reading and writing as in storytelling the result is adjusted according to the audience and ever more to teller’s skills. This means[…]
Several clustering algorithms have been introduced to literature in the last 10 years. Clustering methods usage depends on their complexity, the amount of data, the purpose of clustering and the predefined parameters. This case study, presents three of the most used clustering algorithms, K-means, DBSCAN and Ward’s method.
Many definitions have been stated in literature for the term of spatial data. One of the simplest definition of spatial data, describes spatial data as “information related to the space occupied by objects” (Kolatch, 2001). Moreover, spatial data can be defined as any structured or unstructured data that refers to a specific location of a[…]
The need to analyse, process and extract knowledge from a large amount of data has been a critical subject for computer scientists and researchers since the early years of databases creation. However, in the last decade, the speed at which data is created and stored has increased exponentially and everything indicates that it will continue[…]
