The Top 7 AI Applications Powering Facebook

ByPaul Christiano Last Update on

Facebook has emerged as an AI powerhouse. But what exactly is the social media giant using artificial intelligence for? Let‘s explore the 7 most impressive AI applications that Facebook is leveraging to enhance its products used by billions worldwide.

Artificial intelligence now delivers key functionality across Facebook‘s family of apps and hardware. Major areas transformed by AI include:

  • Understanding Text, Images, Videos
  • Translating Content
  • Recommending Personalized Content
  • Moderating Content
  • Building Virtual Assistants
  • Advancing VR/AR Interactions

Next, we‘ll look at 7 prime examples of artificial intelligence applications deployed at Facebook.

1. DeepText – AI That Comprehends Text

One of Facebook‘s most acclaimed AI achievements has been the development of DeepText. Launched in 2016, DeepText uses deep learning to analyze, understand, and classify textual content.

Traditional natural language processing relied on rules and heuristics. But DeepText takes a very different approach. It utilizes word embeddings and neural networks to actually "comprehend" the meaning of text.

This allows DeepText to understand nuances like detecting sarcasm, parsing slang terms, analyzing context, and more. Facebook AI researchers report DeepText improved classification accuracy of content by 10-15% over previous NLP systems.

Here are some impressive stats on what DeepText enables:

  • 20+ languages – DeepText understands multilanguage textual content
  • 4.7 billion translations – Performed every day across Facebook products
  • 99% accuracy – In detecting unwanted content in posts/comments

DeepText also powers Facebook‘s real-time translation capabilities. Over 2.3 billion people use Facebook in languages other than English. Real-time translations powered by DeepText AI allow all these global users to seamlessly interact.

So whether you‘re reading a post, watching a video, or chatting with friends worldwide, you have DeepText AI to thank for bridging language barriers!

2. Generating Image Descriptions for Visually Impaired Users

In 2016, Facebook AI researchers published their work on automatically generating descriptions of photos to aid visually impaired users.

Over 300 million photos are uploaded to Facebook daily. But visually impaired people miss all the memories and moments captured in these images.

Facebook‘s automated system analyzes images to identify objects, scenes, and actions. It then generates text descriptions like:

"Three young people smiling and posing for a photo at a restaurant."

This "alt text" is read out by screen readers to help blind users understand what a photo contains.

Previously, image descriptions on Facebook had to be manually entered by users. But Facebook found most photos had sparse or blank descriptions, offering little value.

Their AI system significantly improves accessibility. In tests, the AI-generated descriptions provided far more relevant details compared to prior approaches.

Bringing the visual world to life through rich image descriptions showcases AI‘s potential for meaningful social impact.

3. Utilizing AI to Prevent Suicide

A prime example of AI for social good at Facebook is in suicide prevention.

In 2017, Facebook revealed it uses AI pattern recognition to detect potential self-harm and suicidal intent in user posts. Models analyze the user‘s own content as well as comments from friends to identify warning signs.

This allows Facebook to proactively reach out to offer support and resources. Facebook also applies AI to prioritize user reports about self-harm risks for urgent response.

Here are some of the impressive results since rolling out these AI tools:

  • 65% faster response time to potentially harmful situations
  • 100K+ additional people assisted in 2017 compared to prior year
  • 88% success rate in proactive detection using AI

Facebook has invested heavily in AI techniques like natural language processing to rapidly extract warning signs from huge volumes of user data. This showcases AI‘s potential for social good, augmented by human compassion.

4. Cracking Down on Misinformation with AI

Social media faces rampant issues with misinformation, propaganda, and fake news. Facebook has turned to AI algorithms to help tackle this challenge.

One technique is using natural language processing to analyze writing patterns and identify likely fabricated stories. Facebook also employs image recognition to spot visually manipulated photos and deepfake videos.

For coordinated misinformation campaigns, Facebook utilizes network analysis algorithms to detect connections between suspicious clusters of accounts.

By flagging dubious content for third-party fact checkers, Facebook aims to control the spread of misinformation. It‘s also prioritizing original reporting in News Feeds.

But battling misinformation remains an uphill climb. Adversarial networks seek to evade Facebook‘s detection AI, forcing continued innovation.

5. Horizons – Your VR Assistant

AI powers a robust voice assistant called Horizons for Facebook‘s Oculus virtual reality headsets.

Unveiled in late 2022, Horizons lets users control VR experiences via voice commands. You can ask questions, find content, take dictation, and much more.

Horizons can handle multi-turn conversations with contextual follow-up questions. This showcases Facebook‘s heavy investments in conversational AI.

As VR/AR continue growing into the mainstream, expect AI assistants like Horizons tailored for mixed reality to become more commonplace.

6. Spark AR Discovery – Finding Relevant AR Effects

Facebook applies AI to recommend relevant AR effects to users of Spark AR, its augmented reality platform.

The Spark AR Discovery engine utilizes machine learning algorithms to evaluate factors like popularity, related text/imagery, user preferences, followers, and more. It then surfaces personalized AR effect recommendations.

This curation AI sifts through millions of effects to help users discover new ones they‘ll likely enjoy. Spark AR Discovery is a prime example of Facebook successfully incorporating AI recommendations into creative tools.

7. Metaverse World Building with AI

A major priority for Facebook today is building the metaverse – immersive virtual worlds fusing social media, gaming, and real-time experiences.

Facebook‘s social VR platform Horizon Worlds serves as a metaverse testbed for applying AI:

  • Analyzing user-generated content
  • Improving safety
  • Offering recommendations
  • Simulating physics
  • Facilitating interactions through virtual assistants

As the metaverse evolves, Facebook‘s AI researchers are exploring transitioning today‘s AI apps into persistent 3D virtual worlds. VR chatbots, AI characters, and other applications could help make metaverse spaces feel more dynamic, reactive, and human-like.

The Future Looks Bright for AI at Facebook

From text comprehension to suicide prevention to misinformation detection, Facebook relies heavily on AI across its apps. New research papers and tools are published routinely by Facebook AI teams.

But plenty of challenges remain. Accurately modeling human dialog for assistants, combating adversarial media manipulation, reflecting cultural diversity – these present complex AI problems.

As a leader in social platforms and metaverse-enabling hardware, Facebook is poised to keep aggressively pursuing AI advancements across its products.

The next wave of innovations in areas like multimodal AI combining vision, language, speech, and robotics could further revolutionize how Facebook‘s billions of users socialize and express themselves both digitally and physically.

So while today‘s applications of AI at Facebook are highly impressive, they likely only scratch the surface of what‘s to come. We may one day look back at today‘s AI capabilities as quaint and rudimentary compared to the AI-empowered social interactions of the future!
