In recent years, a huge number of job portals have been published on the web. Published job advertisements not only open a great opportunity for learners in identifying their job chances in the future, but also support lecturers and education managers in determining contents needed to be improved in curriculum. Although initial steps towards web of Vietnam's labour market have been established, a united system which can collect, integrate, and analyze job advertisements from different sources has not existed yet. To address this problem, we introduce a system named VNJobSpace. VNJobSpace is composed by six main components which are responsible for collecting, integrating and analyzing job advertisements. In addition, it contains three databases to store job data, schema of each source, and collected curricula. At present, VNJobSpace provides access to more than 700,000 advertisements from 14 job portals in Vietnam. End users can search collected information, obtain prediction for job opportunities, and receive recommendations on essential courses to obtain a desired job.
