Given a text, an automatic keyphrase extraction method retrieves phrase(s) conveying the main points elaborated in the text. The package provided here includes implementations of the following, widely-explored unsupervised approaches.
- Tf-Idf
- TextRank (Mihalcea & Tarau, 2004)
- SingleRank (Wan & Xiao, 2008)
- ExpandRank (Wan & Xiao, 2008)
Each of these methods takes as input one or more text file(s) annotated with Penn Treebank PoS tags (see a sample input file). A separate output file containing a list of keyphrases is created for each input file when a collection of files are given as input. Optionally, in case the set of input text files has its own gold standard keyphrases, each method generates its overall performance scores in terms of recall, precision, and F-score. A ReadMe file with each method describes how a user can set this and other parameters specific to each method.
