Event detection

Definition

Event detection is the process of identifying significant occurrences or changes in data, particularly within the realm of financial information, using algorithms and natural language processing techniques. This involves analyzing large volumes of unstructured data, such as news articles and social media posts, to pinpoint events that could impact markets, such as mergers, acquisitions, or economic reports. By recognizing these events promptly, financial institutions can make informed decisions and react quickly to emerging trends.
