At both the SLC and LEP large samples of Z/sup 0/ /yields/ b/bar b/ will soon be available. The challenge is to find experimental techniques to inclusively tag and identify the various particles b quarks may fragment into. The work described here makes use of the new generation of close-in tracking devices which will achieve unparalleled precision in particle trajectory resolution. Some of these devices provide three-dimensional information which is crucial in solving the pattern recognition problem discussed below. In the case where only two-dimensional information is available other than tracking information may be required. The tracking system is used to extrapolate tracks into some preselected point. The result is a picture of many crossing tracks and the problem is to find the real vertices among all the possible combinations. 1 ref., 3 figs., 1 tab.
