One of the common misconceptions concerning financial data is that it is all numerical. While this might be the case with things like accounting ledgers, most data exists in the form of text which is largely unstructured. And one recent survey indicates that 90% of the world’s central banks are grappling with how to derive value from their unstructured data. Consider, for example, the numerous written reports that investment managers and traders need to comb through to make informed decisions, or the many external communications with clients that take place over email and chat. Few sectors are nearly as data heavy as finance, an area that oversees hundreds of millions of transactions every day.

Align processes and performance management to adjust for AI’s inclusion on the team. Both the chief investment officer and portfolio managers should be onboard to help with challenges and integrate the technology and investment teams. Once the objectives of NLP/G adoption are truly shared, an organization can pursue them in a coordinated fashion.11 Close collaboration between technology, investment, data science, and strategy teams can help drive NLP and NLG adoption.

Financial Sentiment

NLP for financial documents aids in automated compliance checks by extracting relevant information from legal texts and policy documents, ensuring adherence to intricate regulatory frameworks. NLP algorithms identify patterns in large volumes of textual data to detect fraudulent activities. Financial institutions can swiftly pinpoint suspicious activities and prevent fraud by analyzing transaction narratives and customer communications. To use the mining analogy, NLP/G performs a refining step that concentrates the ore before analysts spend time on evaluation.

Unstructured information within a bank poses challenges when it comes to extracting insights and this is where NLP comes in. Equity performance is one area of that banks need attention and NLP tools provide a clear analysis of operations. By using NLP for market forecasting, HSBC explores stock market performance and offers recommendations based on prevailing market conditions. The success of companies in the financial industry depends on risk management procedures adopted and NLP is supporting in this area. Unlike the past when banks took long to get the whole market view, NLP is streamlining the process through #data extraction tools.

Artificial intelligence and machine learning in the banking and financial industries: use cases

Retrieving information from unstructured resources that financial institutions have problems accessing. Credit scoring seems to be one of the more common applications for AI in finance, and vendors now are offering products that can help assess credit scores for customers with little or no credit history. Many of these products use NLP to gauge the creditworthiness of a customer from their digital footprints. He holds a PhD in Environmental Shareholder Value from the University of Freiburg.

When these two technologies are coupled, they can successfully handle massive volumes of data. Every investor’s main aim is to maximize their wealth over time without being aware of the underlying distribution provided by stock prices. Data science, machine learning, and nonparametric statistics can be used to anticipate investment strategies in financial stock markets. NLP is a very effective way to predict time series such as stock prices in the financial sector. It has the unique ability to determine complex nonlinear relationships and to accurately approximate nonlinear functions.

Data Quality

For example, NLP can analyze vast amounts of publicly available feedback on social media, public forums, and consumer review websites, to broadly determine how clients feel about a particular brand. In a sector where trust is everything, financial institutions can never be too aware of how their reputations stack up against the competition. Natural language processing is the key to unlocking the value in this data—it’s a powerful solution for making sense of this wealth of data at machine speed by adding context that makes it searchable and actionable. For example, a model might be trained to flag sections of text that address specific areas of interest, such as financial risk or client sentiment. A leading investment firm followed many of these principles in their path to NLP/G adoption.

Today, companies use Artificial intelligence (AI) approaches to spend less time on data discovery and more time on deriving insights from the data. It streamlines that process, extracting relevant entities and interpreting them within the context of the document. The machine learning model trained with historical underwriting data then evaluates the extracted information, detecting potential red flags and helping the agents assess the risks related to the particular case. With NLP, machines extract the information from the user’s writing or speech in real-time and generate the relevant answers.

How NLP is Transforming the Finance Industry

Banks make decisions based on NLP tools, which further accelerates the preparation of financial reports. Banks need accurate information about their operations and NLP tools are changing the landscape by helping them make decisions based on customer and market trends. Companies such as Green Key Technologies have developed NLP solutions for the financial industry with their latest innovation around trading desks. Financial institutions use their tools in voice information and analysis of trading processes.

NLP/G technology is most mature in the postinvestment phase, with applications already in use at some large investment management firms. Because portfolio and index performance are naturally structured data, NLP/G engines can readily use these inputs to generate performance attribution reports and periodic investor reviews. These outputs’ programmatic nature combined with NLG’s ability allows for the creation of client on-demand reporting. Figure 4 shows a machine-generated portfolio narrative that was written with NLP/G technology and made available to investors shortly after period close. As the investment management industry increasingly adopts AI solutions, new technologies—including natural language processing—are helping investment analysts with their most “human” responsibilities, including making investment decisions. Text is unstructured data, and it’s inherently harder to use unstructured data, which is where natural language processing comes into play, Shulman said.


Natural language processing (NLP) models can be trained to review unstructured content, and spot issues or trends that may impact financial markets. Practical examples of natural language processing in action include speech recognition and intent parsing used by voice assistants and chatbots in customer services, and information retrieval and sentiment analysis of corporate documents and news feeds. NLP techniques and algorithms help to translate the raw textual data into meaningful insights across several areas in finance. Traders, portfolio managers, analysts, banks and other financial organizations strive to improve their financial analysis, and NLP and ML have become the technologies of choice. NLP is used across the financial industry, from retail banking to hedge fund investing. Such NLP techniques as sentiment analysis, question-answering (chatbots), document classification and topic clustering are used to work with unstructured financial data.

To gather useful investment data, the NLP-powered search engine extracts the components, concepts, and notions included in these papers. When environmental parameters are unclear, it assists in achieving the highest potential growth rate. By filtering out good and unattractive equities, data envelopment analysis may be used to select a portfolio. The data gathered in the past may be utilized to forecast the start of a trading session and a portfolio. Investors can disperse their present capital among the various assets using this information.

Reshaping text analytics – is AI a game changer for analysts?

In the last five years, several deep learning algorithms have begun to outperform humans in a variety of tasks, including speech recognition and medical picture analysis. Recurrent neural networks (RNN) are a particularly successful approach of forecasting time series, such as stock prices, in the financial realm. From retail banking to hedge fund investment, NLP is employed in the financial industry. To work with unstructured financial data, NLP techniques such as sentiment analysis, question-answering (chatbots), document categorization, and topic clustering are utilized. Sentiment analysis helps to categorise news based on positive and negative sentiment and shows potential impacts on stock prices, but it also has more subtle uses like retrieving customer emotions and testimonials on products. NLP allows procurement of customer feedback and taking crucial financial decisions based on customer testimonials.
