Video Content Moderation Technology

Whether you’re running a centralized knowledge-sharing platform or an employee social network, video moderation technology can help your organization prevent unwanted content from filling up its library and ensure that it complies with corporate standards.

AI-powered content moderation tools are trained to recognize the characters and characteristics of text, images, audio and videos posted on your online platforms. They also analyze sentiments, recognize intent, detect faces and identify figures with nudity or obscenity.

Object Detection

Object detection has become a key component in many use cases that leverage video moderation technology. Whether it’s social media, print-on-demand, messaging apps or live-streaming platforms, object detection can help protect users from offensive imagery as soon as it’s shared.

Using computer vision techniques to automatically analyze images and videos to identify inappropriate content can save time and resources that would otherwise be required to manually review every piece of user-generated content. Additionally, object detection can identify multiple objects and images from a single file, streamlining the moderation process by having one AI model review all of an organization’s media files instead of several separate processes.

Machine learning and deep neural network-based approaches offer a number of methods for object detection, including region-based convolutional neural networks (R-CNNs), which first select a few proposed regions from an image and then label their categories and bounding boxes. The R-CNN models are able to detect multiple objects and features within each proposed region.

Another approach is a model that can identify a series of objects by combining the features of each object with the features of its neighbors. The algorithm can then determine whether a particular object is part of the larger group and if so, provide a more accurate description of its appearance.

The YOLOv3 model, for example, is a state-of-the-art real-time object detection system that can identify objects in videos at up to 15 frames per second. The model is capable of detecting very small, far-off objects and can also recognize the position of observed people in videos.

Besides moderation applications, object detection is also used to support self-driving cars by identifying objects like pedestrians and traffic lights. This is necessary for autonomous vehicles to navigate the world in a safe and efficient manner.

Object detection is also becoming increasingly important for online marketplaces and other businesses that deal with large volumes of user-generated content (UGC). In the case of these companies, it can be critical to find any infringing designs or characters to avoid legal penalties and a negative impact on their brand reputation. Object detection can even be used to check for nudity, sexually suggestive imagery or other harmful content that could lead to a drop in conversion rates or a deterioration of a company’s image.

Object Recognition

Object recognition is a computer vision technique used to identify objects or people in images and videos. This technology is a great tool to automate content moderation, as it can review large amounts of content more quickly than humans. It can also flag the most offensive content, saving organizations time and money.

Several online forums, messaging apps, and streaming services use computer vision to detect inappropriate and offensive content. This type of content moderation technology can be useful for organizations of all sizes, as it can quickly and accurately weed out harmful content and reduce the number of times that users are required to manually review their content.

In addition to identifying the content itself, computer vision can also identify objects in images that are harmful, like weapons or nudity. It can even automatically replace images that have been previously flagged as offensive, helping to decrease the amount of anonymized content that an organization needs to filter.

Another way that object recognition can help with content moderation is through its ability to generate natural language descriptions of the images and video that it identifies. This type of moderation can be useful for businesses that need to moderate content in real-time and are not capable of hiring human moderators.

The main difference between object detection and image recognition is that object detection produces bounding boxes for each object in an image or video. These boxes are static for an image but dynamic for a video, as they represent where each object is located in the image.

Using these boxes, the object recognition model can identify different objects within an image or video and assign them a specific label. For example, if you have a picture of two dogs, one will get the label “dog” and the other will get the label “dogs.”

Object detection is a computer vision technique that uses both machine learning and deep learning methods to identify objects in an image or video. These techniques can be used to recognize a variety of objects, including people, animals, and objects that are not visible in an image or video.

Natural Language Processing

NLP is a key technology behind the success of many applications, from chatbots to digital assistants and search engines. NLP enables computers to process, interpret, and synthesize information that is otherwise difficult for humans to decipher.

As a result, NLP has become an essential part of everyday life and is increasingly applied to a wide range of industries. Across retail, healthcare, and even chatbots, NLP is used to understand user queries and provide accurate and relevant responses.

For online platforms, NLP is also used to analyze comments and remove harmful content in real time. Natural language processing algorithms can identify bullying, sarcasm, and other forms of harassment in comments by understanding the tone of the message and labeling it accordingly.

In video content moderation, NLP is a key tool for removing objectionable videos or images and protecting audiences from harm. AI can quickly evaluate user-generated content and proactively remove or block it, while keeping human teams in the loop as necessary.

Developing accurate content moderation models is not an easy task. It requires the ability to process a huge amount of data in a short amount of time while maintaining accuracy. Additionally, the volume of content on a global scale means that it is crucial to have models that recognize multiple languages and the social contexts within which they are spoken.

There are a variety of NLP libraries for developers to use when creating their own NLP tools. These include Apache OpenNLP, Stanford NLP, and NLTK.

These libraries offer a variety of NLP algorithms for text moderation, including tokenizers, sentence segmentation, part-of-speech tagging, named entity extraction, and chunking. They can also help with sentiment analysis, text classification, and coreference resolution.

Another way in which NLP can be used in content moderation is to weed out spam. By feeding the technology with a list of terms that are typically used in spam content, NLP can easily identify and filter out unwanted or inappropriate UGCs.

While this can reduce the workload for human content moderators, it is important to remember that humans still have the final say over any pre-screened content. This ensures that everyone involved in the moderation process has a clear understanding of what is and is not acceptable.

Machine Learning

Machine learning is an important tool in video content moderation technology. It helps to make predictions about content and can remove inappropriate content automatically. This makes it faster and more accurate than manual review.

It’s used behind chatbots and predictive text, language translation apps, Netflix suggestions, and many social media feeds. It also powers autonomous vehicles and machines that diagnose medical conditions based on images.

ML algorithms help to make predictions about user-generated content, including images and videos. These can be categorized as safe or not safe, and then flagged for human review.

AI can also be used to identify images that contain harmful content, such as sexually suggestive comments and racial slurs. This can be done through the use of vision-based search techniques and object character recognition (OCR).

Another common type of machine learning is unsupervised learning. This technique is useful when there are fewer data labels and more generalization is needed. This technique uses hidden Markov models, k-means clustering, and Gaussian mixture modeling to find patterns in the data.

This kind of machine learning works well for video content moderation because it can identify inappropriate content at scale and more quickly. In addition, it can label videos based on viewer history and preferences to create content recommendation engines.

It can also be used to monitor videos in real time and detect deepfakes, videos that represent fictional characters, actions, or claims. These are a threat to the reputation of websites and the privacy of their users.

In the case of YouTube, ML algorithms help to determine if a video is hate speech or violates copyright laws. They can also flag videos that are violent or violate the site’s terms of service, preventing them from being displayed.

Using AI in video moderation is one of the best ways to protect users and businesses from malicious or damaging content online. It can also help to identify unauthorized accounts and delete them for good.

It can also be used to check images and texts for a range of issues, including cyberbullying, explicit or harmful content, fake news, and spam. Having AI do this can save companies an enormous amount of money and time, since they don’t have to hire enough employees to manually review the content created by their users.
