Improving the accessibility of biomedical texts by semantic enrichment and definition expansion

We present work aimed at facilitating the comprehensibility of health-related English-Spanish parallel texts by means of the semantic annotation of biomedical concepts and the automatic expansion of their definitions. In order to overcome the limitations posed by the scarcity of resources available for Spanish, we propose to exploit existing tools targeted at English and then transfer the produced annotations. The evaluations performed show the feasibility of this approach. An enriched set of texts is made available, which can be retrieved, visualized and downloaded through a web interface.
