In this blog post, we present a brief overview of NLP, the enormous amount of data that financial services companies need to wrestle with, the advantages of NLP in dealing with unstructured data, and key NLP use cases in this sector.

Given the exponential growth of unstructured data year over year (the IDC estimates unstructured data growth to continue at 55-65% each year), Natural Language Processing (NLP) can become a critical AI technology for financial firms. Using NLP, research analysts and data teams can extract fast and accurate insights, in minutes not months, for decision making, increasing ROI, and meeting business objectives.

Solving the Big Data Dilemma with NLP

NLP is a branch of AI that enables computers to understand text and audio data in the same way that humans can—with the human language. By combining computational linguistics and computer science, computers can understand text data and interpret intent, relevance, and sentiment.

Data is the key for any company to understand its clients, predict client behavior, and turn insights into results. However, what differentiates a successful company is it’s ability to obtain clean data, analyze it and transform it into actionable results.

While data that comes in a structured format is easier to understand and analyze, large amounts of unstructured data are nearly impossible to use without NLP. Through text classification and ML algorithms, NLP can help break down unstructured data at scale.

Types of Unstructured Data

Unstructured data comes in various forms such as customer transactions, blogs, online communities, social media, surveys, reviews, chats, emails, and more. Data from these sources is constantly evolving with every tweet, blog post, review, etc. Therefore, businesses across industries face challenges in monitoring these sources and extracting the most relevant data needed to uncover insights that lead to an ROI.

NLP use cases vary from translating text into different languages, responding to commands, and researching, extracting, and summarizing large volumes of text from the past and even in real-time. If you’ve ever used a chatbot, speech-to-text, virtual assistant, or interacted with Siri, Alexa, or Google, you have used NLP in some form. However, businesses are increasingly finding value in using NLP to achieve business objectives, increase workforce efficiency and advance business operations.

NLP Use Cases in Finance

One industry in which natural language processing is especially helpful is financial services—across asset, quantitative, and wealth management firms, insurance companies, and banks. Financial services teams must sort through a large quantity of data from various sources such as corporate transactions, statements, news, social media posts, reviews, etc. and evaluate the data to ensure that companies and/or individuals are in line with certain practices and are reliable.

Wealth managers, investment bankers, and traders can use NLP tasks for data mining on corporate news, mentions, statements, and more to create investment signals that can help predict stock market movement. On the other hand, insurers and bankers can use NLP to mine data to assist in underwriting and identifying credit risk.

Sentiment Analysis 

Sentiment analysis uses AI and NLP to identify, extract, and analyze textual data to understand the overall attitude and emotion of the text. Once the data is evaluated, a sentiment score will be generated to determine whether the data is positive, negative, or neutral. Sentiment analysis is most commonly used by hedge funds in analyzing financial news to predict stock market trends and movements.

For example, traders and investment bankers can use NLP to research and analyze ESG compliance and mergers and acquisitions news. With sentiment analysis, financial teams can evaluate consumers sentiment around specific companies.

Named Entity Recognition

Named Entity Recognition (NER) uses artificial intelligence and NLP to identify specific companies or individuals (named entities) mentioned in unstructured text data. Once the named entities are identified, they are classified into pre-defined categories such as company names, person names, locations, products, services, etc.

NER plays an important role with hedge funds and investment management in financial news analysis as it enables analysts to quickly research, find, and extract specific information. Wealth and portfolio managers and investment bankers can quickly find the exact mentions of entities with NER to determine which financial actions to take.

Text Summarization

Text summarization uses AI and NLP to take large quantities of data and extract the most relevant details of the text. The most important points within the document are summarized while keeping the meaning of the data. With large amounts of data constantly generated, financial analysts do not have the time to read through every work and manually extract the important points.

Financial analysts can use machine translation and text summarization to receive summaries of important documents and not have to worry about human error. NLP enables text summarization applications to add insightful context and conclusions to summaries as well, further assisting financial teams on the next steps.

Speech Recognition 

Speech recognition allows software to use artificial intelligence to recognize spoken language and convert it into text data. Banks have already implemented speech recognition for customer service calls, which has resulted in a massive decrease in operational costs. A subset of speech recognition and a new advancement that banks are beginning to adopt is voice recognition.

Voice recognition uses artificial intelligence to match a customer to his/her voice. HSBC recently announced that it will be the first bank to implement voice recognition for telephone banking customers.
