Recommendation is a process which plays an important role in many applications as WWW . The main objective of this paper is to show various challenges regarding to the t echniques that are being used for generating recommendations. Recommendation techniques can be classified in to three major categories: Collaborative Filtering, Content Based and Hybrid Recommendations. By giving the overview of these problems we can impro ve the quality of recommendations by invent ing new approaches and methods, which can be used as a highway for research and practice in this area.
