Using Azure Search custom skills to create personalized job recommendations
This blog post was co-authored by Kabir Khan, Software Engineer II , Learning Engineering Research and Developement.
The Microsoft Worldwide Learning Innovation lab is an idea incubation lab within Microsoft that focuses on developing personalized learning and career experiences. One of the recent experiences that the lab developed focused on offering skills-based personalized job recommendations. Research shows that job search is one of the most stressful times in someone’s life. Everyone remembers at some point looking for their next career move and how stressful it was to find a job that aligns with their various skills.
Harnessing Azure Search custom skills together with our library of technical capabilities, we were able to build a feature that offers personalized job recommendations based on identified capabilities from resumes. The feature parses a resume to identify technical skills (highlighted and checkmarked in the figure below.) It then ranks jobs based on the skills most relevant to the capabilities in the resume. Another helpful ability is in the UI layout, where the user can view the gaps in their skills (non-highlighted skills in the figure below) for jobs they’re interested in and work towards building those skills.
Figure one: Worldwide Learning Personalized Jobs Search Demo UI
In this example, our user is interested in transitioning from a Software Engineering role to Program Management. Displayed in the image above you can see how the top jobs for our user are in Program Management but they are ranked based on our user’s unique capabilities in areas like AI, Machine Learning and Cloud Computing, resulting in the top ranked job on the Bing Search and AI team which deals with all three.
How we used Azure Search
Figure two: Worldwide Learning Personalized Jobs Search Architecture
The above architecture diagram shows the data flow for our application. We started with around 2000 job openings pulled directly from the Microsoft Careers website as an example. We then indexed these jobs, adding a custom Azure Search cognitive skill to extract capabilities from the descriptions of each job. This allows a user to search for a job based on a capability like “Machine Learning”. Then, when a user uploads a resume, we upload it to Azure Blob storage and run an Azure Search indexer. Leveraging a mix of cognitive skills provided by Azure and our custom skill to extract capabilities, we end up with a good representation of the user’s capabilities.
To personalize the job search, we leverage the tag boosting scoring profile built into Azure Search. Tag boosting ranks search results by the user’s search query and the number of matching “tags” (in this case capabilities) with the target index. So, in our example, we pass the user’s capabilities along with their search query and get jobs that best match our user’s unique set of capabilities.
With Azure Search skills, our team was able to make the personalization of job search, a desirable capability among job seekers and recruiters, possible through this proof of concept. You can use the same process we followed to achieve the same goal for your own careers site. We open sourced the Skills Extractor Library that we used in this example and made it available in a container.
Please be aware that before running this sample, you must have the following:
- Install the Azure CLI. This article requires the Azure CLI version 2.0 or later. Run az –version to find the version you have.
- You can also use the Azure Cloud Shell.
