Limitations/Next Steps
Limitations
1. Single Source: Job data is only from single source (only Linkedin)
2. Only June/July data could be crawled, no time series analysis could
be done with our own data
3. No way to detect job duplication (single job, multiple posts)
Next Step
1. Scrape data from multiple sources (indeed, monster)
2. Run the script weekly so calculate job data over time
3. Calculate the similar of two job posts to reduce duplication
4. Store the job into MySQL database
