In the experiments presented in this paper we focus on the creation and evaluation of domain-specific web corpora. To this purpose, we propose a two-step approach, namely the (1) the automatic extraction and evaluation of term seeds from personas and use cases/scenarios; (2) the creation and evaluation of domain-specific web corpora bootstrapped with term seeds automatically extracted in step 1. Results are encouraging and show that: (1) it is possible to create a fairly accurate term extractor for relatively short narratives; (2) it is straightforward to evaluate a quality such as domain-specificity of web corpora using well-established metrics.
