Analysis and design of object oriented is onemodern paradigms for developing a system. In this paradigm, there are several objects and each object plays some specific roles. Identifying objects (and classes) is one of the most important steps in the object-oriented paradigm. This paper makes a literature review over techniques to identify objects and then presents six taxonomies for them. The first taxonomy is based on the documents exist for a domain. The second taxonomy is based on reusable previous knowledge and the third one relies on commonalities in a domain. The fourth taxonomy is concerned with decomposing a domain. The fifth taxonomy is based on experience view and sixth one is related to use the abstraction in a domain. In this paper, the constraints, strengths and weaknesses of the techniques in each taxonomy are described. Then, the techniques are evaluated in four systems inside an educational center in a university. A couple of approach is recommended for finding objects, based on some practical experiences obtained from the evaluation.
