Chatbots are computer programs that interact with users using natural languages. This technology started in the 1960’s; the aim was to see if chatbot systems could fool users that they were real humans. However, chatbot systems are not only built to mimic human conversation, and entertain users. In this paper, we investigate other applications where chatbots could be useful such as education, i...

This paper presents an iterative Content Based Image Retrival(CBIR) system with Relevance Feedback (RF), in which M-band wavelet features are used as representation of images. The pixels are clustered using Fuzzy C-Means (FCM) clustering algorithm to obtain an image signature and Earth Mover’s Distance (EMD) is used as a distance measure. Fuzzy entropy based feature evaluation mechanism is used...

A Product of Experts (PoE) model is a probabilistic model which combines a number of individual component models by multiplying their probabilities. A typical PoE model is an exponential family Harmonious introduced by Welling et al. In this paper, we apply a hierarchical PoE model, Complex-Cell Model (CCM), to image retrival and compare the performance with a kind of standard harmonious model,...

This paper presents an architecture of an information retrieval system that use the advantages offered by mobile agents to collect information from different sources and bring the result to the calling user. Mobile agent technology will be used for determine the traceability of a product and also for searching information about a specific entity.
