Abstract:

In this paper, we present a new research direction, {\it automatic linguistic indexing of pictures}, for data mining and machine learning researchers. Automatic linguistic indexing of pictures is an imperative but highly challenging problem. In our on-going research, we introduce a statistical modeling approach to this problem. Computer algorithms have been developed to mine numerical features automatically extracted from manually annotated categorized images. These image categories form a computer-generated dictionary of hundreds of concepts for computers to use in the linguistic annotation process. In our experimental implementation, we focus on a particular group of stochastic processes for describing images. We implemented and tested our ALIP (Automatic Linguistic Indexing of Pictures) system on a photographic image database of 600 different semantic categories, each with about 40 training images. Tested using more than 4600 images outside the training database, the system has demonstrated good accuracy and high potential in linguistic indexing of photographic images. Such a system can potentially be used in many areas such as semantic Web and counter terrorism.
