I believe PageRank isn't as important as it was 10 years ago. Besides, you don't need explicit links to create links. Off the top of my head, the following could be used to link resumes: keywords, references, educational institutions, co-authors on papers, and former employers. All these can be extracted fairly well from a document as structured as a resume, and then you can go wild with link analysis. At the very least, it would allow you to filter the chaff, and enough care could be given to a dataset as small as 75,000 documents to take care of preprocessing, some manual curation, etc. and yield some decent results. If you wanted to, you could even compute PageRank scores in R on your laptop for a dataset that small (and that would probably be the only computationally intensive part of it, after POS tagging and ML model fitting). As a bonus, the effort would go a long way to help your recruiting in the future.
