What are the programs / tools for collecting and analyzing information from sites!?

Question

Search Engine Optimization

I would like something strange, namely, automating the collection, storage and analysis of open information on the network based on the provision of RSS sites, namely:
1. compiling average portraits of employees according to available job descriptions, so that you can plan a career and training.
2. articles of interested authors from news feeds. Interested in topics: hardware, mobile technologies, columnists.
