Review: Programming Collective Intelligence
Programming Collective Intelligence is a book about applying data mining techniques to analyse collections of data. There is submerged information in Ebay prices, in Facebook profile networks, in collections of movie reviews, in news sites, in the stockmarket; this book by Toby Segaran shows ways to extract, visualise, understand, and predict that information.
Estimating salaries by comparing job ads »
This is clever: job classified aggregator Indeed estimates a job’s salary when it lacks that data by comparing the text to ads that do have a salary posted.
When people search for jobs, they want to put in a salary floor. They don’t want to see jobs that don’t at least pay a certain amount. Problem is most job listings on the Internet don’t include salaries.
What Indeed did was built a system that estimates salaries on all jobs.
We use a proprietary methodology based on an analysis of similar job listings that include salaries. We start by extracting salaries from all job listings containing this information – about a fifth of the total – and then estimate salaries for the rest.
Example: CFO jobs in NYC that pay more than $200k per year
