What is keyword co-occurrence in Bitcoin research?
Could you elaborate on the concept of keyword co-occurrence in the realm of Bitcoin research? I'm particularly curious to understand how this technique aids in understanding the broader themes, trends, or associations within Bitcoin-related literature. Does it involve analyzing the frequency of specific keywords appearing together in documents? And how does this help researchers gain deeper insights into the evolving landscape of Bitcoin and its implications for the cryptocurrency market? I'm also wondering if this methodology is commonly applied across various finance and cryptocurrency studies or if it holds specific value in the context of Bitcoin research.
