The applications for artificial intelligence are effectively limitless, and this field of computer science is extremely promising. Worldwide revenue from the AI market is projected to reach as high as 190 billion U.S. dollars by 2025. Companies, particularly from software and information technology services industries, are investing heavily in artificial intelligence. At the same time, AI-focused startups have been gaining momentum and attention from investors, with the funding of AI-startup companies nearly increasing by fivefold from 2015 to 2018. The majority of startup companies working in the AI market are focusing on applications for machine learning, a type of artificial intelligence which allows computers to learn without human assistance. At last count, at least 31.7 billion U.S. dollars have been invested in this particular AI category. Many startups have also bet on the natural language processing market, which involves voice and speech recognition and text prediction, to name a few applications. This particular AI market is forecast to grow to 12.4 billion U.S. dollars in 2020.
Another important market within the artificial intelligence industry is big data. The term "big data" describes the enormous amount of data that inundate businesses on a constant basis, as well as the industry which has grown around attempts to collect, analyze, and act upon that data. The ability to harness big data effectively allows businesses to make faster, smarter decisions and improve short- and long-term strategic planning. Due to the size and complexity of these massive data sets, artificial intelligence is seen as one of the answers to finding meaningful answers within the sea of data available. Revenue from big data and business analytics worldwide added up to 168.8 billion U.S. dollars in 2018. By 2022, this figure is forecast to pass the 274.3 billion U.S. dollar mark for the first time.
