Job scraping or scraping job vacancies on the web has long been one of the main cases of large-scale scraping in the industry. Over time, the quality of work data scraped via Web-scraping has improved thanks to the availability of better and easier-to-work tools, faster data cleaning methods and the growth of machine learning and AI.
Why scratch work data in particular?
In case you have decided to delete the working data, you must first decide what you will use the data for. In case you are scraping job lists for yourself – looking for jobs you should apply for, your path and procedure will be different. If you want to aggregate jobs and list them on your job board, your methodology will be different. Again, when it comes to conducting market research using relevant employment data, the method should vary. We will discuss all the use cases and the procedures for each.
One of the most common uses of job postings from the web is to create a job aggregation website, better known as a job board site. When creating job boards, the most important thing to keep in mind is that each deleted post should be kept clean and up to date. The presence of unwanted values in your job offer due to unclean data can lead to a dead end for your business. At the same time, having vacancies that were filled a month ago is also not a good idea.
Although both are essential, another interesting option would be to classify the data by locating certain keywords in the messages. The categorization can be based on location, sector, years of experience, required job title, etc. These data points can help customers sort through job postings on your website and find the job of their dreams.
Job offers can say a lot about the market, corporate hiring strategies, average salaries in different positions, and technological trends. Businesses can use it to study their competitors, trends in a specific industry as a whole, and more. When you delete job data for market research, you do not need to recover the entire job. Instead, you can scrape the specific data points that will be used in your analysis. In this way, the scraping will be faster and you will no longer need to sort the data during the analysis.
While it is not common, a person like me can use web scraping to achieve their own goals – finding a job for themselves. The amount of data to be scratched for this will be much less than the last two. When you delete the job data to match your profile, you need to make a list of keywords that a job posting should have, and then start deleting the job data based on the matches.
You can delete messages containing at least 70% of the words or more. The percentage should be defined according to your specific needs. Also, you may want to correct a few words and leave the rest of the correspondence variable. For example, if you are based in New York and want to work as a software engineer, you can keep these two words as essential, while you can have other words such as Java, Python, Ruby, Docker, etc. , with a match requirement of 75%.
What are the challenges of deleting job data?
When extracting work data, the most important challenge we face is extracting data points such as the location and role of work. Since most job offers appear as a paragraph with a header and there is no defined template for it, it can be difficult to separate the data points. Job postings from different websites may follow different models.
And sometimes, job postings on the same sites may also follow different models, if any. In such cases, you will need to use some level of machine intelligence to locate the data points. For example, if you have a numeric value next to the word “Salary” or “Compensation” or “CTC”. Then you can expect the next number to be your expected salary.
How to start scratching work data?
Scraping data from the web is not difficult. But dispose of it effectively so that it can be consumed by the business system. This can sometimes be intimidating. However, if you plan to delete data from a few specific websites. You can use a tool like BeautifulSoup in Python to analyze and get the data, in case you can code. There are several paid, non-code-based tools on the market, but each involves a certain amount of manual and learning effort.
What are the steps after scraping the data?
If you delete work data from the web. It is important to make sure that the data is clean and then to store it in a database. Storage is just as important as the scraping process. In case you can classify the data and store it in a database with labels. It will become much easier for the sales team to use. Keeping the data in its raw format can make it unusable and expose the entire web scraping effort.
For small projects, where scraping efforts involve a unique configuration. You can run your code on your local computer, get the data, and clean it up for use.
