A VLBI survey of compact Broad Absorption Lines (BAL) quasars with
  BALnicity Index BI=0
  We present high-resolution observations, using both the European VLBI Network
(EVN) at 1.7-GHz, and the Very Long Baseline Array (VLBA) at 5 and 8.4-GHz to
image radio structures of 14 compact sources classified as broad absorption
line (BAL) quasars based on the absorption index (AI). All source but one were
resolved, with the majority showing core-jet morphology typical for radio-loud
quasars. We discuss in details the most interesting cases. The high radio
luminosities and small linear sizes of the observed objects indicate they are
strong young AGNs. Nevertheless, the distribution of the radio-loudness
parameter, log(Ri), of a larger sample of AI quasars shows that the objects
observed by us constitute the most luminous, small subgroup of AI population.
Additionally we report that for the radio-loudness parameter, the distribution
of AI quasars and those selected by using the traditional balnicity index (BI),
BI quasars differ significantly. Strong absorption is connected with the lower
log(Ri), and thus probably with larger viewing angles. Since, the AI quasars
have on average larger log(Ri), the orientation can cause that we see them less
absorbed. However, we suggest that the orientation is not the only parameter
that affects the detected absorption. The fact that the strong absorption is
associated with the weak radio emission is equally important and worth
exploring.
