Abstract:
Online news media usually cover the same news events. It would be interesting to understand, how similar are the descriptions of these events. In other words to explore how a distinct news event, is described by different news media. Can we safely conclude when two or more event descriptions refer to the same event? This research aims to investigate similarities in Greek news articles and provide new data on the field, as there is no relevant research. To do so, news article’s text is extracted, processed and analyzed with automated methods. To establish an understanding of similarity, three similarity settings are explored and special focus is given in examining the degree of similarity between news articles that cover the same event. In some cases results are inconclusive, while in others results show that groups of news media share the exact same articles with little or no modifications at all. The similarity analysis of news articles is a complex task and relies on many different
factors that need to be addressed.
