Emoji analysis helps AI detect sarcasm in tweets

It’s not possible to detect emotions expressed in tweets — all thanks to emoji.

A team of researchers from MIT have developed an algorithm capable of detecting the sentiment and emotions expressed in tweets. It uses a neural network to analyze emoji contained in the tweets, allowing the underlying meaning to be interpreted.

In an article for the MIT Technology Review, the researchers explained how emoji provides a convenient starting point for the AI. Since emoji already acts as a kind of “labelling system” for emotional content, the presence of certain emoji in a tweet is a good indicator of its overall sentiment.

The neural network uses emoji to assess tweets for general emotion. It then springboards from the initial analysis to start looking for elements of sarcasm. In a trial, the emoji-trained algorithm proved to be “far better” at detecting sarcasm than a comparable one without the training.

“Because we can’t use intonation in our voice or body language to contextualize what we are saying, emoji are the way we do it online, ” said MIT Media associate professor Iyad Rahwan. “The neural network learned the connection between a certain kind of language and an emoji.”

The researchers collected a dataset of over 55 billion tweets for the experiment. They then proceeded to train the algorithm with a subset of 1.2 billion tweets containing various combinations of 64 popular emoji. The test was conducted with “several” benchmarks previously shown to be effective at surfacing sentiment indicators in text.

Although the emoji-trained algorithm proved to be effective, experts are sceptical it could have practical applications. Gary King, director of the Institute for Quantitative Social Science at Harvard University, told the MIT Technology Review that the detected sarcasm “really doesn’t matter” if it’s too nuanced for a human reader to appreciate. Rahwan also acknowledged that the benchmarks used “don’t capture” the subtleties of sentiment that humans can recognize.

Even so, the team’s research demonstrates that emoji-based analysis of existing material could be an effective way to improve the accuracy of text-based algorithms.

“If machines are going to cooperate with us, then they’re going to have to understand us, and emotion is really hard,” Rahwan said.

Rahwan and his fellow researchers have created a website that lets you assist the algorithm, known as DeepMoji, in furthering its training. You can upload your own messages to have the algorithm analyze the sentiment expressed in them. The service will return the emotions as emoji that best represent the sentence.

It’s been called “The Olympics of Tech.”

More than 35,000 attendees, 1,250+ startups, and 800+ investors are converging on Toronto for a now-sold-out Collision 2022 — back live for the first time in two years. 

North America’s fastest-growing tech conference takes place June 20-23 at Toronto’s Enercare Centre. It is part of a series of technology conferences that include Web Summit in Europe and RISE in Hong Kong.

Welcoming attendees back after the 2020 and 2021 virtual editions of the conference, Paddy Cosgrave, founder and CEO of Collision & Web Summit said, “I just can’t tell you how excited I am to be back,” before introducing Toronto mayor John Tory.

“The numbers of people that come to this conference demonstrate the eagerness that everyone has to be together after a long pandemic,” said Tory. “It speaks to the impact of Collision itself, that so many people are here.”

“You come because you think it matters,” he continued. “And we have to make it matter. We have to make it make a difference — not just with respect to technology.”

Tory then outlined why Collision is right at home in the city of Toronto: “This is one of the fast-growing tech conferences in the world, for a reason, and there is a reason that Toronto is hosting it.”

“If you’ll forgive me a moment of truthful immodesty, we have cemented ourselves as a global hub for technology and innovation,” said Tory, before welcoming attendees to explore the city and see what it can do for their businesses. 

“You can be part of this Toronto success story.”

Collision kick-off

Led by co-hosts Sunil Sharma (Managing Director of Techstars Toronto) and Casey Lau, opening night featured an impressive lineup of speakers from a range of sectors. Guests included:

To warm up the audience, however, a series of breakout startups presented their pitches, as a preview of what’s in store for attendees this week. Eight startups, three of which are Indigenous-owned (see asterisks), came to the stage. Startups featured were:

Collision and the state of the world

Collision is coming back at an interesting, particularly volatile time for the global economy and tech market. Inflation has skyrocketed, and the costs for everything from basic groceries to buying a car or home has led to a tremendous feeling of uncertainty. 

For starters, recent weeks have seen the cryptocurrency market crumble, with even long-term investors starting to think of exiting the space. CNBC recently reported that the price of bitcoin fell more than 9% in 24 hours to $18,642.22, as of about 2 p.m. ET on Saturday, June 18. 

Venture Capitalists have been pouring money into startups throughout the pandemic, at what we can now call an unsustainable level. The result? Overvaluation — a big risk to employees, as one CEO wrote for Forbes.

Ultimately, there is an air of optimism coming from Collision, where an enthusiastic and packed crowd were eager to kick off the event. 

Agenda

Attendees will be able to choose from an absolutely massive selection of sessions, across several tracks and curated lists of sessions.

With the aforementioned crypto crash at the top of many minds, the crypto track, featuring sessions like Mass Adoption: Crypto’s next challenge and How to regulate cryptocurrencies, is sure to be popular. 

Those interested in startups can look forward to sessions like How Calgary is winning the global talent competition, How to recession-proof your startup, and 3 big mistakes founders make when building early-stage tech teams, among others.

Betting on yourself with entrepreneur Tanya Gough

Armed with a passion for narrative literacy and a knack for content architecture, creative-industry entrepreneur Tanya Gough is driven to help make the writing process more interactive, collaborative and social with StoryBilder.

“Whatever you do will be wrong…until it isn’t,” says creative-industry entrepreneur Tanya Gough, about navigating other people’s feedback while building a tech platform. 

Armed with a passion for narrative literacy and a knack for content architecture, Gough has created StoryBilder. It is an adaptive story-generating platform that transforms the way writing happens. The platform is aimed at helping storytellers build out their plots, characters and entire worlds to make the writing process more interactive, collaborative and social.

Gough is one of 50 women across Canada selected for the first cohort of the BANFF Spark Accelerator for Women in the Business of Media. With support from Western Economic Diversification Canada, this new program offers training, mentorship and market access to women entrepreneurs ready to grow or launch their own businesses in screen-based industries.

Leigh Doyle, partner and VP at DJG and a fellow cohort participant, interviewed Gough as part of a series showcasing the entrepreneurs in the BANFF spark program. 

Leigh Doyle: You’re a big believer in narrative literacy. Can you tell me a bit about what is narrative literacy, and why do all of us need to sort of relearn it?

Tanya Gough: Narrative literacy is the ability to recognize and understand narrative structure in the stories around us. It matters because we’re surrounded by story, and it’s an incredibly persuasive format for transmitting information. When we understand story, not only are we better able to express our own stories and be heard, but it also gets easier to recognize when we’re being manipulated or lied to. And that gives us better defenses against fake news and makes it easier to differentiate between fact and fiction.

Doyle: How did the idea of StoryBilder come to you?

Gough: I was hanging out with a friend of mine who is a game designer, and we were brainstorming for an app we were working together on. At that moment, StoryBilder just happened for me. I knew exactly what it had to be. 

I wanted to create an environment where people could not only write their stories, but that could also help them organize their thoughts and ideas. And, if they were new to writing or didn’t know what to do next, there would be support and tools to help them improve their craft. I also wanted to ensure the platform would foster creativity, which I think is missing in the market.

Here’s what it is and how it works: 

Doyle: Who is StoryBilder for? 

Gough: StoryBilder is currently designed to support creative writing, particularly for fiction novels. But the technology is adaptable. I’ve already got screenwriters who want to use it as a planning tool for their scripts. I have game developers who want to use it for world building. I even had a D&D master ask me if he could use it to build campaigns — and the answer to this is yes. StoryBilder is built around a narrative construction model that can be applied to any storytelling format. It can be used for a lot of different things.

Doyle: What author would you be thrilled to see using StoryBilder? 

Gough: It’s so hard to pick! The obvious answer is George RR Martin. The idea of this huge epic world, with tons of characters spanning multiple books and managing all of the interconnected pieces, is a long-term ambition of StoryBilder. But, personally, from more of a literary geek perspective, I would say Michael Chabon who wrote The Amazing Adventures of Kavalier & Clay. It’s probably my favorite book of all time. Chabon writes these incredibly dense, complexly structured storylines with interconnecting plots and massively detailed backgrounds. This is the type of narrative I’m keeping back of my mind as I develop StoryBilder. 

Doyle: When will StoryBilder be available to the public? 

Gough: Right now, we’ve got beta testers helping me find the last of the bugs, and I’m doing some extra design work. Then we’re launching this summer. I’m looking forward to getting it into the market and getting the word out.

Doyle: You’ve owned a boutique CD and video store, the world’s largest Shakespeare video catalogue and created content for companies like BlackBerry, Shoppers Drug Mart and more. How have you seen the entrepreneurial landscape change for women over the course of your career?

Gough: If five years ago, you asked me if there would be any substantial change for women in business in my lifetime, I would have said no. And clearly I won’t see parity in my lifetime — just look at the numbers. But what I have seen — especially in the last few years — is a rising opportunity for entrepreneurial women to connect with each other. This is thanks to social media and groups on large networks like Facebook. 

The women in these groups are not only talking about their challenges in a really honest way, but they are incredibly generous about helping each other and supporting each other through not only the bad stuff, but making sure that we’re all succeeding together. Change is happening now. It’s not going to happen as fast as people hope, but it will happen as long as we continue to support each other and continue to speak openly. Support and solidarity are incredibly empowering.

One of my big drivers for creating StoryBilder is this knowledge that more women need to have businesses to create a path for the next generation to follow. Someone needs to be out in front. And that’s where I need to be, with the rest of the women taking the hits and leading the way.

Doyle: What lessons do you have for entrepreneurs building tech platforms like Story Bilder? 

Gough: The first is to forget about funding. Sure, there are stories about people getting funded at the idea stage, but it’s rare, and you’re new and inexperienced. Find another way and don’t waste all of your time chasing the money until you have something solid in hand.

The second is whatever you do will be wrong…until it isn’t. Take the time to experiment and try new approaches to make sure you’re solving the right problem in the right way. Likewise, if you are looking for funding, be prepared to hear you’re not ready — a lot.

Finally, do it because you love it. Starting a business is way too much work to do if you don’t wake up every morning excited to be working on it. Which isn’t to say you’re going to love it every day, but if you’re waking up every morning not knowing if you’re building the right thing, go do some market research or get out.

Digital transformation for a more sustainable world

Published

Share this:

Sure, they’re confronted with business challenges every day, but the world’s top business leaders have a significant part to play in solving the world’s challenges — economic, technological, societal and educational. 

As Christian Klein, Co-Chief Executive Officer of enterprise application software company SAP succinctly puts it in a blog post for the World Economic Forum, “Companies today don’t just prosper based on their financial performance, but on how they make a positive contribution to society.”

Ahead of the World Economic Forum’s 2020 meeting — taking place Jan. 21-24 — Klein outlined how digital transformation can be a force for good in the world, and be a way to create a more sustainable world.

Critical minds, he starts, might wonder why companies would take the time, considering their primary goal of making money. “These critics should not underestimate the power of the consumer,” he argues, explaining that while customers do consider their decisions based on products or price, but the company’s values. Employees act in a similar way, choosing to join companies “that embrace their responsibility towards humankind and the planet.”

Almost every person on the planet knows that technology plays a profound effect on just about every facet of our lives, from jobs to wages to health to security. Meanwhile the need for business to undergo digital transformation, simply to stay relevant and alive, is hardly big news anymore. 

“But transformation is also about a change of culture, which requires a radical rethinking of people, processes and technologies,” Klein writes. Included in this are “tectonic changes” that go into a company, and how employees interact within the whole system. 

“And just like a business cannot digitally transform unless – or until – its people transform, I believe that, while they come with their own environmental costs, technology and digitalization can play a crucial role in developing solutions for a better tomorrow.” 

Some examples? Blockchain’s potential to add traceability (and by extension, trust) to food supply chains. The empowerment of people with disabilities through AI, which, when properly applied, can reduce bias in the hiring process. Smart cities, powered by everything from sensors to open data to better supply services and protect resources.

“There is no doubt that technology and digital transformation break down silos and create transparent and unified data for objective decision-making,” Klein writes. “But even more so: they change how companies manage their relationships with the wider world.”

Creating a sustainable world requires us to look beyond corporate borders, toward the communities around us, creating an ecosystem of trust “that allows us to exchange ideas to create a safety net for the most marginalized.”
