Beyond TF-IDF: Exploring BM25 for Enhanced Document Ranking and Vectorization

BM25, short for Best Matching 25, is an information retrieval algorithm designed to enhance the ranking of documents based on their relevance to a given query. Combining elements of both term frequency-inverse document frequency (TF-IDF) and probabilistic models, BM25 introduces nuanced parameters for better adaptability in real-world scenarios. Intuitively, BM25 improves upon traditional TF-IDF by considering document length and term saturation, offering a more dynamic approach to relevance scoring. From a technical perspective, BM25 incorporates adjustable parameters like k1 and b, influencing the impact of term frequency and document length normalization, respectively. This adaptability makes BM25 highly customizable, enabling optimization for different datasets and search scenarios. The algorithm's robustness is further underscored by its ability to handle sparse data, making it suitable for a wide range of applications, including search engines, recommendation systems, and information retrieval tasks.
