Bibliometrics, text mining, and vizualization analyses to support verification and specification of PICO.

We aim to obtain a fast overview of the HTA question and to refine-specify the PICO for information retrieval, using bibliometrics, text mining, and vizualization tools. The PICO question is a well-established format within the HTA process. Depending on the HTA question the PICO can be difficult to verify and limit. To support the HTA-project groups and the informaton specialistst to establish the best PICO, we use bibliometrics, text mining, and vizualization analyses to present a fast, predictable and more objective view of the information landscape
