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

4. Scrape data from multiple sources (indeed, monster)

5. Run the script weekly so calculate job data over time

6. Calculate the similar of two job posts to reduce

duplication

7. Store the job into MySQL database
