A Beginner's Guide to CV Parsing

By Jane Clements


Online job boards have made the job of advertising job vacancies extremely easy. That and perhaps the volume of folks that are trying to find work. Recruitment chiefs no longer suffer the dilemma of not having even a single applicant to present to their clients. A survey conducted by Pew Internet Research asserts any single virtual job advertisement receives 300 job applications typically. That's a large amount of resumes for recruiters to handle. Considering a hiring officer takes around 5 minutes to have a look over the resume, establish if it is already in the firm's recruitment database and, if it doesn't yet exist, add it in the database, he will be able to process only a dozen resumes each hour. That's less than 100 resumes in a day. Hiring officials simply have too many critical tasks to allocate a few days and an hour simply updating databases.

Enter the CV parser. It's also called resume parser, CV extracter and resume extracter. It is a spin-off of the info analyzing and extracting systems utilized by U.S. military intelligence in the 1990s. A CV parser is specialised computer software that takes information from resumes, sorts the information and stores it in the recruitment database. The largest benefit from employing a CV parser is the significant period of time that can be saved by taking the dreary and repeated jobs from human hands. It allows recruitment personnel to focus on the more human-centric aspects of their business, for example talking with clients and interviewing candidates.

There are nonetheless, disadvantages to the use of CV parsing. For one thing, CV parsers, irrespective of how wonderful they are, are never 100% accurate. This is because resumes come in various formats, layouts, languages, content and file types. Regardless of how intelligent our computers have become, they remain a bunch of machines without the facility to understand the complications of the human language. But that's okay, considering human information sorters are about only 96% correct and software parsers are at about 90% to 95%. Is it worth the 6 percentage points less in accuracy to save tons of time? Yes, for most hiring firms, it definitely is.

How Does CV Parsing Work?

The best CV parsers only require that you drag the files from your drive into your database. They can recognise most CV file types, including .doc, .pdf and .rtf. They can also link to your email so that anything received from candidates through e-mail are also immediately stored in your database. The software then extracts the data stored in these files and tries to order them into a selection of fields, for example abilities, qualifications and work history. How a CV parser recognizes different sorts of information is a touch too technical for recruiters to even bother with, but here's a layman's look at the different ways a CV parser works.

1. Keywords. It looks for keywords that can be used to identify other parts of your Resume. For example, if it finds a five-digit number predated by 2 letters and a space, the software translates it as a postal code in the U.S. And assumes that the text before it is a street address. Naturally, it might be wrong. This explains why keyword-based parsing isn't as accurate as the other 2.

2. Grammar. The software is provided with a language's grammar rules so it distinguishes terms and phrases in different combinations. This sort of parsing is generally more accurate than keyword-based.

3. Statistics. It utilizes numerical models to translate language. Exactly how that happens is tough to explain, but we know that recruiters still have to mark the data they would like to be removed from the resumes.

CV parses depend on using different combinations of keyword-based, grammar-based and statistic-based algorithms to investigate and organise info into the best categories possible.

In spite of its otherwise minimum accuracies, a CV parser is useful to any recruitment firm, especially to people who have taken their services to the Web. It streamlines the hiring process by getting rid of the drudgery of manually encoding info into your database and processing big numbers of resumes in an effective and fast demeanour. A CV parser also opens up more time to focus improving applicant experience along with providing better services to your clients. It's a valuable business tool actually.
