From the lexicons: NLP in the construction of the Lexicon of Market Drivers in Spanish*

Abstract

In our approach when analyzing and interpreting financial news, we state that apart from the need of a tailored-made lexicon it is critical to design market drivers lexicons, defining a “driver”as the factor or force that has a material impact on a specific activity on another entity, which is contextually dependent and which affects the financial market at a specific time. Therefore,  our proposal contemplates three key aspects: first, the conceptualization of the market driver typology, second, a brief explanation of Natural Language Processing (NLP) techniques applied in the construction of market drivers lexicons to finally explain the relevance of the market drivers lexicons in the interpretation of financial news and its correlation to the market movements
