Online image retrieval system is more important in the real world environment where the users submitted their queries to retrieve the images. The main aim of mining is extracting valuable information from huge volume of textual or image datasets. The user queries are mined to enhance the web searching which is extremely useful to improve the retrieval effectiveness. The image retrieval accuracy is measured based on the user satisfaction level. Automatic annotation is utilized for operating over high dimensional text documents or image contents. Different online image retrieval techniques are available like Latent Semantic Indexing (LSI), Markovian Semantic Indexing (MSI) etc., but these techniques cannot retrieve the images accurately due to the lack of semantic knowledge about the user submitted high level keywords. Moreover the LSI and MSI have less image retrieval accuracy. Hence, this research work focussed on the improvement of the accuracy of the image retrieval system.
