When companies in the railway industry publish annual and quarterly reports, ESG reports and other filings, GlobalData analyses the text and identifies individual sentences that relate to disruptive forces facing companies in the coming years. Artificial intelligence is one of these topics - companies that excel and invest in these areas are thought to be better prepared for the future business landscape and better equipped to survive unforeseen challenges.
To assess whether artificial intelligence is featuring more in the summaries and strategies of companies in the railway industry, two measures were calculated. Firstly, we looked at the percentage of companies which have mentioned artificial intelligence at least once in filings during the past twelve months - this was 64% compared to 28% in 2016. Secondly, we calculated the percentage of total analysed sentences that referred to artificial intelligence.

This analysis provides an approximate indication of which companies are focusing on artificial intelligence and how important the issue is considered within the railway industry, but it also has limitations and should be interpreted carefully. For example, a company mentioning artificial intelligence more regularly is not necessarily proof that they are utilising new techniques or prioritising the issue, nor does it indicate whether the company's ventures into artificial intelligence have been successes or failures.
GlobalData also categorises artificial intelligence mentions by a series of subthemes. Of these subthemes, the most commonly referred to topic in the fourth quarter of 2021 was 'computer vision', which made up 33% of all artificial intelligence subtheme mentions by companies in the railway industry.
