A Study on Timeframe based Radical Event Detection on Online News Archive
Journal Title: Engineering and Technology Journal - Year 2020, Vol 5, Issue 7
Abstract
In the field of Natural Language Processing, Event detection has been an active area of research. While most of the work emphasizes on detecting all possible events by using datasets comprising of news article belonging from a broad range of time and location (collected either from a single data source or multiple data sources), this work focuses on detecting an event using short timeframes of News Articles extracted from an Online News Archive. Also, this is a non-targeting approach when it comes to detecting the theme or category of event it focuses on but becomes a targeted one as it tries to put all its focus on detecting one major event when applied on a timeframe. While other approaches are based on various techniques like semantic graphs, clustering algorithms, topic detection and tracking for event detection, this approach detects events with the help of a filtering mechanism combined with a novel threshold. This algorithm leverages detection of trending characteristics of an event in a timeframe and filtering news articles which show similar characteristics. And finally, we evaluate our algorithm with precision, recall and the percentage of articles which are actually related to the event in a timeframe termed as dominance percentage.
