None of the knowledge is mine. What I have learnt is from others. You will find such similar ideas in many books. But I wanted a book that is precise, simple to understand, makes sense and is freely available to anyone. A straight to the point book. This is the effort of many years, boiled, purified and refined to the very basic principles. There are too many people to thank for, far too many to even list them down in this book.
Many events in news articles don’t include time arguments. This paper describes two methods, one based on rules and the other based on statistical learning, to predict the unknown time argument for an event by the propagation from its related events. The results are promising – the rule based approach was able to correctly predict 74% of the unknown event time arguments with 70% precision.
