You can read the description of the algorithm and its evaluation in the paper "Text Rank: Bringing Order into Texts" by Rada Mihalcea and Paul Tarau.
I have made a quick and dirty implementation of TextRank in R (http://www.r-project.org/) for keywords extraction only.
My implementation has two differences to the algorithm presented in the above mentioned paper:
- it calculates weights of the edges based on the number of instances when two nodes are connected (it is not used in the calculation of ranks though)
- it allows circular references, where a node has an edge to itself (used in the calculation)
I have used three R libraries to speed up implementation:
- tm (text mining) for preprocessing text to be analyzed
- openNLP for part of speach tagging
- graph for constructing graphs
I'd like to emphasize once more that this is a really quick and dirty implementation.
Please find source code here.
