Abstract
Traditional feature-based or text processing techniques tend to assign the same annotation to all the im-
ages in the same cluster without considering the latent semantic anecdotes of each image. In this re-
search, we propose the Chinese lexical chain processing method which is a botom-up concatenating pro-
cess based on the intensity and the degree of a lexical chain (LC) to extract the most meaningful LCs as
anecdotes from a string. It requires minimum computation that allows sharing characters/words and fa-
cilitating their use at fine granularities without prohibitive cost. In the experiment, this method achieves
a precision rate of 84.6%, and gains acceptance from expert rating and user rating of 84% and 76.6%,
respectively. In performance testing, it only takes 0.007 s to process each image in a collection of 18,000
testing data set.

1 Introduction
Due to the rapid growth of digital technology, it is impractical to annotate a huge amount of
images manually. Traditional research in this area focuses on content based image retrieval
