Discovered: Mar 3, 2023 07:56 david-mccullars/text_rank: Ruby implementation of TextRank solution to ranked keyword extraction<— not sure how up to date this is, last update 2 years ago –> QUOTE: TextRank is an unsupervised keyword extraction algorithm based on PageRank. Other strategies for keyword extraction generally rely on either statistics (like inverse document frequency and term frequency) which ignore context, or they rely on machine learning, requiring a corpus of training data which likely will not be suitable for all applications. TextRank is found to produce superior results in many situations with minimal computational cost.
