This contribution introduces a placement web-service which has been developed in the context of the TENCompetence Integrated Project. The web-service uses Latent Semantic Analysis (LSA) to calculate similarity between documents in learner portfolios and content in the current learning network of the learner. In the first part of the paper the placement problem in learning networks is introduced. Next we discuss the architecture of the current web-service prototype and describe our evaluation approach. Several limitations and future developments are discussed at the end of the paper.
