A Machine Learning Approach to Document Retrieval: An Overview and an Experiment.
Hsinchun Chen · 1994
In this article we first provide an overview of AI techniques and then present a machine learning based document retrieval system we developed. GANNET (Genetic Algorithms and Neural Net System) performed concept (keyword) optimization for user-selected documents during document retrieval using the genetic algorithms. It then used the optimized concepts to perform concept exploration in a large nenvork of related concepts through the Hopfield net parallel relaxation procedure. Our preliminary experiment showed that GANNET helped improve search recall by identifying the underlying concepts (keywordr) which best describe the user-selected documents.
