Indian Origin scientist’s team predict outcome of tweets

Arizona: A team of researchers including Indian origin scientist developed a method which will be able to predict with the accuracy of the seventy per cent the outcome of tweets. It will predict if the tweets that are part of an ongoing debate or a movement, whether they will become part of a later and even violent protest later.

The study from researchers at Arizona State University, Texas A&M University and Yahoo and funded in part by the US Military’s Office of Naval Research looked at 2,686 Twitter posts to create a system that reliably spots future online protesters.

“The ways in which protest-related events affect a person are not observable, resulting in a lack of knowledge of factors operating at that time causing his next post to be a declaration of protest,” wrote lead researchers Suhas Ranganath, Fred Morstatter and colleagues from Arizona State University.

“A user is subject to various types of influence in his past and many of them are in conflict with each other. This may lead to ambiguities on whether his posts will contain declarations of protest in the future,” they added.

The paper titled “Predicting Online Protest Participation of Social Media Users” was published as part of the proceedings of the Association for the Advancement of Artificial Intelligence (AAAI) conference in Phoenix, Arizona, recently.

To reach this conclusion, the team observed tweets regarding the Nigerian general election in 2015, which eventually sparked widespread protests due to irregularities and militant violence.

The team employed Brownian motion theory to design the formula — a theory that is usually employed to track the movement of particles as well as model stock market fluctuations and other highly complicated systems, www.nextgov.com reported.

The findings can also be applied to scenarios when the complete spreading mechanism is not known like in the case of terror-related tweets.

“In these scenarios, we go into the history of the user and see who have tried to interact with him and the nature of the interactions. So the individual user’s response to the attempt of organizations like IS (Islamic State) to interact with him can be modelled using the proposed method,” the team told Defense One website.

The researchers, however, caution that predicting a protest tweet is different than predicting the moment of actual radicalisation

The paper is part of a $750,000 grant from the Office of Naval Research to study how crisis manifests itself in social media.(IANS)

Micro-blogging Site Twitter to Bring ‘Hide Replies’ Feature in June

“We are updating our rules in the next few weeks so they’re shorter, simpler and easier to understand,” they added

As part of the efforts to make its platform appear less toxic, Twitter is planning to give people an option to hide replies to their tweets, thereby giving users more control over the nature of conversation they would like to have on the platform.

“Starting in June, we’ll be experimenting with ways to give people more control over their conversations by giving them an option to hide replies to their Tweets,” Donald Hicks, Vice President, Twitter Service and David Gasca, Twitter’s Senior Director, Product Management, Health, wrote in a blog post on Tuesday.

While the feature has the potential to make trolls invisible, it could make it difficult for users to correct wrong statements made by others.

Other social media platforms like Facebook and Instagram already give users much more power in terms of dealing with the comments to their posts, including the option to delete them.

Twitter last year said that making the platform free of abuse, spam and other things that distract from the public conversation is its top priority.

The microblogging site on Tuesday said it had got a lot faster and better at curbing abusive behaviour and hateful content.

“This time last year, 0 per cent of potentially abusive content was flagged to our teams for review proactively. Today, by using technology, 38 per cent of abusive content that’s enforced is surfaced proactively for human review instead of relying on reports from people using Twitter,” Hicks and Gasca wrote.

“The same technology we use to track spam, platform manipulation and other rule violations is helping us flag abusive Tweets to our team for review,” they said.

Twitter said 100,000 accounts were suspended for creating new accounts after a suspension during January-March 2019 — a 45 per cent increase from the same time last year.

With a focus on reviewing this type of content, Twitter said it had expanded its teams in key areas and geographies.

“We’ll make it easier for people who use Twitter to share specifics when reporting so we can take action faster, especially when it comes to protecting people’s physical safety,” Hicks and Gasca wrote.
