Big-Data Analytics and Cloud Computing
In the online job recruitment domain, matching job seekers with relevant jobs is critical for closing the skills gap. When dealing with millions of resumes and job postings, such matching analytics involve several Big Data challenges. At CareerBuilder, we tackle these challenges by (i) classifying large datasets of job ads and job seeker resumes to occupation categories and (ii) providing a scalable framework that facilitates executing web services for Big Data applications.
In this chapter, we discuss two systems currently in production at CareerBuilder that facilitate our goal of closing the skills gap. These systems also power several downstream applications and labor market analytics products. We first discuss Carotene, a large-scale, machine learning-based semi-supervised job title classification system. Carotene has a coarse and fine-grained cascade architecture and a clustering based job title taxonomy discovery component that facilitates discovering more fine-grained job titles than the ones in the industry standard occupation taxonomy. We then describe CARBi, a system for developing and deploying Big Data applications for understanding and improving job-resume dynamics. CARBi consists of two components: (i) WebScalding, a library that provides quick access to commonly used datasets, database tables, data formats, web services, and helper functions to access and transform data, and (ii) ScriptDB, a standalone application that helps developers execute and manage Big Data projects. The system is built in such a way that every job developed using CARBi can be executed in local and cluster modes.
