Social media data analysis is a popular research domain since the last decade. Detecting the events and sub-events from social media posts that require special attention is one of the key research problem in this domain with wide range of applications. Particularly in the field of crisis management, event and sub-event detection can be of great benefit assisting the public safety departments to plan for quick responses. In this paper, we review the existing researches in the field of event and sub-event identification from social media based microblog data for disaster management. The contribution of the paper includes the study of research papers from two different aspects - i) Computational Steps for performing a research on event and sub-event detection from social media data, ii) Computational Techniques briefly discussing the methods adopted in recent studies pertaining to event and sub-event detection and summarization. This study would help the future researches in the social media data analytics domain for crisis management.ĭespite the significant efforts made by the research community in recent years, automatically acquiring valuable information about high impact-events from social media remains challenging. We present EviDense, a graph-based approach for finding high-impact events (such as disaster events) in social media. One of the challenges we address in our work is to provide for each event a succinct keyword-based description, containing the most relevant information about it, such as what happened, the location, as well as its timeframe.

View the profiles of people named Valou Iconie. Facebook gives people the power to share and makes the world more open and connected. Our evaluation shows that our method outperforms state-of-the-art approaches for the same problem, in terms of having higher precision, lower number of duplicates, and presenting a keyword-based description that is succinct and informative.

A preliminary version of this work was presented as a 4-pages short paper at ICWSM 2018. Join Facebook to connect with Matthaios Matthaiou and others you may know. Mining the correlation has attracted widespread attention in the research community because of its advantages in understanding the dependencies between objects. In this paper, a correlated graph pattern searching scheme has been proposed, that is, provided with a query g as a structured pattern (i.e., a graph), our algorithm is capable of retrieving the top-k graphs that most likely correlated with g. Traditional methods treat graph streams as static records, which is computational infeasible or ineffective because of the complexity of searching correlated patterns in a dynamic graph stream. It will also air on Sky Cable (Ch 955 HD and 155 SD).įor exclusive concert privileges such as access to zoom pits, backstage content with the artists, and limited-edition merch, visit to get tickets.In this paper, by relying on sliding windows to separate graph streams in chunks, we propose a Hoe-PGPL algorithm to handle the top-k correlated patterns searching from a dynamic perspective. The six-hour continuous virtual event will be streamed live on multiple platforms such as Facebook, YouTube, TikTok, and more on December 31, from 7 p.m. And we are bringing to bear every learning, every talent, and every skill we have gained this 2020 and applying it to our event BYE2020."Ī "Best of the Year Awards" will also be held, and digital platforms such as Facebook, Spotify and TikTok, and other notable partners will be part of a special segment dedicated to awarding the finest local creators for their record-breaking achievements in digital content and entertainment. "Fortunately for us technology has allowed us to re-imagine what we can do for music entertainment and live events. "What BYE2020 delivers is a way for every Filipino to look back at all of the challenges we have faced, and enter 2021 a bit more hopeful," they said.
