![]() 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. We evaluate our approach on a large collection of tweets posted over a period of 19 months, using a crowdsourcing platform. ![]() 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. We further improve the results of our algorithm by incorporating news from mainstream media. A preliminary version of this work was presented as a 4-pages short paper at ICWSM 2018. 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. Celebrity Edge will be joined by her sister ship, Celebrity Apex, in 2020, and two additional ships in the Edge Series will follow in 20.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. Then, in spring of 2019, Celebrity Edge crosses the Atlantic again to offer guests stunning vistas of the Mediterranean with a range of seven- to 11-night sailings visiting iconic cities, including Barcelona and Rome.īookings for Celebrity Edge are now open at or through a travel agent. Her inaugural season will be spent sailing alternating seven-night eastern and western Caribbean cruise itineraries, with her Maiden Western Caribbean voyage departing on December 9, 2018, and her Maiden Eastern Caribbean voyage departing on December 16, 2018. On November 6, 2018, Celebrity Edge will begin her transatlantic voyage to her home port at T25 at Port Everglades in Fort Lauderdale, Fla. “This achievement demonstrates once again our capacity to deliver right on time ships of the highest quality to our most demanding customers.”įollowing the Celebrity Edge check-signing and delivery ceremony, attendees made their way across the Chantiers de l’Atlantique shipyard for the ceremonial keel laying of Celebrity Apex, where a 762-ton block was lifted in the air and a lucky coin was placed on the dock before the block was lowered into position. “Thanks to the confidence Celebrity Cruises granted us and to the exceptional level of cooperation between our respective teams, we are proud to have designed and built one of the most innovative cruise ships ever,” added Castaing. ![]() “There are so many aspects of Celebrity Edge that are more groundbreaking than we could have ever imagined, and it is all a testament to the hard work, creativity and talent of everyone who helped bring this magnificent ship to life.” “Today is a very special day for all of us as we have been eagerly anticipating this moment for more than four years,” said Lutoff-Perlo. “Their work continues to transform the way our guests experience the world.” ![]() “The Celebrity team has done an outstanding job and I cannot thank the Chantiers de l’Atlantique team enough for delivering this game-changing ship and for their ongoing partnership,” said Fain. ![]()
