Self-organizing maps
| Hi-index | 0.00 |
In this paper we present a novel system that can automatically mark up text documents into XML. The system uses the Self-Organizing Map (SOM) algorithm to organize marked documents on a map so that similar documents are placed on nearby locations. Then by using the inductive learning algorithm C5, it automatically generates and applies the markup rules from the nearest SOM neighbours of an unmarked document. The system is adaptive in nature and learns from errors in the automatically marked-up document to improve accuracy. The automatically marked-up documents are again arranged on the SOM.
