We present an ongoing project which aims to reveal the nature of the brightest unknown UV sources identified in observations carried out with theUltraviolet/Optical Telescope onboard Swift. Our sample comprises 60 fields of 17?17? around symbiotic stars which were the main targets of Swift observations conducted by our group during the past four years. Here we detail the pipeline procedure developed to identify UV sources and search for variability in their flux, and the first results from the five fields already studied. The UV sources identified are likely associated with cataclysmic variables, white dwarfs, and active stars. Additionally, we present the complementary part of this investigation that intends to include optical spectroscopic followup, and mining of X-ray and infrared databases to support the characterization of UV sources.
