FIFA-based Topic Similarity Computation Modal
Jing Ju Zhu · Journal of Northeastern University · 2003
An event topic similarity computation technique for the fifth TDT techniquelinking detection was put forward. Domain knowledge base is used to upgrade topic similarity computation technique from lexical analysis to domain knowledge analysis. The linking detection technique is used to decide whether two documents (or stories) are on the same event topic. There are two steps in the analysis procedure which includes using FIFA modal to identification content topic, and using LDM modal to compute event topic similarity. Experiment results show that precision and recall percents of the model are 64% and 69%.
