Not Safe For Work(NSFW) Content is moderated by Artificial Intelligence(AI) for digital platforms. While many solutions have already advanced beyond this, there are still a number of technical challenges around identifying NSFW content. These challenges do not just affect accuracy, but also the efficiency of AI systems in real-world applications. In this post, I explore the primary technical challenges in AI NSFW detection, and illustrate the implications for accuracy as well as discuss the possible solutions being pursued.
Contextual Ambiguity
Contextual ambiguity is one of the biggest challenges in AI-based NSFW detection. The reason AI systems fail to capture this context is because of the ambiguity in the context in which the content is created/shared, again leading to both false positive and false negative cases. An image that is medically relevant, but contains nudity could be flagged as inappropriate. At the same time, minor cases of NSFW, which hide behind the AI filters, fly under the radar because of how oblique they are. According to some researchs, these AI technologies work with approximately 85% accuracy and hence it is bad for segementation of context, so, they need more accuracy.
Visual and Textual Nuances
The nuances of video and text content prove to be another giant barrier that women must adjust for. AI shall not only be trained on clear NSFW signals but also on signals which may not be considered NSFW in many contexts, but would be against some community guidelines at certain points. Natural language is so complex and double entendres and cultural references can misdirect AI, making us less safe. While recent improvements mean that detection rates have probably got a little better since then, and the 15% to 20% inaccuracy quote would already have included an early dataset containing the equivalent to under-18s and non-explicit content solutionsusuion efforts, we may still have a significant problem classifying a whole swathe of more nuance content correctly.
While the former refers to scalability and the latter to real-time processing.
Making sure AI systems can scale and do real-time processing is arguably one most important feature that some big platform with lots of user-generated data. As more and more content are released, it becomes harder to achieve the same accuracy and speed in detecting NSFW content. Large dataset processing latency: slow processing of vast datasets can also slow down the workflow of AI systems, thus inappropriate content would be available for an unacceptable amount of time. Platforms say they are working to improve processing architecture to help eliminate these delays and enable near-instantaneous content moderation.
Training Data Limitations
The AI capability to detect such Not Safe For Work (NSFW) content relies on the quality and especially diversity of the training data. Training data is often biased, leading to AI models with a skewed view of the world, creating problems such as targeting or neglecting certain groups of users or types of content. Developers must still worry about things like privacy, ethics of data collection, and having balanced datasets. Anonymization, diversification of data sources, as these are the two major strategies [(in place to combat it)](http://www.kdnuggets.com/2016/04/big-data-bias-data.html).
Changing Standards: It is Impossible to Keep Up
The rules for what constitutes NSFW content are not set in stone; they change along with changing social norms and laws. The adaptive nature of AI systems: AI systems must hence constantly adapt to an inevitable evolution, which in turn demands continuous learning and updating (re-training ) of AI models. Which is quite an adaptive challenge, because it means you always need to be on the alert and allocate resources to remain up to date with the newest standards and user expectations.
For all AI challenges in detecting NSFW images, technical hurdles has to ensure a way to find innovative solutions and keep on improving them. Tackling these problems is very important for keeping digital spaces safe and in line with social expectations and legislative requirements. Hopeful one day, the advancement of AI technology will allow these obstacles to be scaled, bringing further down the road a more reliable and less obstructed system of NSFW content moderation.
