The performance of text-based image retrieval is highly dependent on the tedious and inefficient manual work. For the purpose of realizing image keywords generated automatically, extensive work has been done in the area of image annotation. However, how to treat image diverse keywords and choose appropriate features are still two difficult problems. To address this challenge, we propose the multi-view stacked auto-encoder (MVSAE) framework to establish the correlations between the low-level visual features and high-level semantic information. In this paper, a new method, which incorporates the keyword frequencies and log-entropy, is presented to address the imbalanced distribution of keywords. In order to utilize the complementarities among diverse visual descriptors, we tactfully apply multi-view learning to

search for the label-specific features. Thereafter, the image keywords are finally produced by appropriate features. Conducting extensive experiments on three popular data sets, we demonstrate that our proposed framework can achieve effective and favorable performance for image annotation.
