Abstract
Twitter is currently one of the most popular platforms for disseminating information about events happening around the world. Especially but not only for emergency events, it is crucial to know when and where the events are taking place. Unfortunately, identifying the geo-location of an event discussed in Twitter is a very challenging task mainly due to the brevity of the messages (i.e., tweets) and their subjective nature. In the literature, some efforts have been made to address this task, but they are characterized by substantial limitations such as the use of exclusively text analysis techniques, or the need for keywords or possible candidate locations. This paper proposes a new process for automatic event geo-localization which relies on both textual and spatial/temporal use of content posted on Twitter without using some prior knowledge about the event to be located. As shown by experimental results, our proposal achieves a good accuracy rate and outperforms two well-known baseline approaches related to the geo-location of events in Twitter.

Microblogging is a broadcast medium that allows users to create small digital content such as short texts, links, images, or videos and share it with an online audience. This communication medium is relatively new with respect to traditional media, it has gained increased attention among online users thanks to its immediacy and portability
Acampora et al.: Automatic Event Geo-Location in Twitter on information often unknown such as a set of candidate locations; iii) getting locations through an exclusively textual analysis of the tweets. Starting from these considerations, this work proposes a new approach to geo-localize an event discussed in Twitter which relies on both textual and spatial/temporal use of content posted on Twitter without using some prior knowledge about the event to be located
The emojis can be an important element to describe emotions and moods about personal events and events featured on Twitter [26], we remove them together with numbers and non-alphanumeric symbols since they cannot contain useful information for the purpose of detecting and geo-localizing events
