This paper presents the automatedannotation system that can detect the tweets whichcontain critical information or not. Annotation is doneat tweet level with three labels by using the publiclyavailable annotated datasets. LibLinear classifier isused to build a model for automatic tweets annotation.The annotation system also creates disaster relatedcorpus with new tweets collected from Twitter API andannotated on real time manner. The performance ofthis model is evaluated based on different disasterrelated datasets and new Myanmar_Earthquake_2016dataset derived from Twitter.
