| Abstract: |
Research of temporal Information Extraction was regarded as a subtask of named
entity recognition in 1990's. To date, the scope of this research is broadened, ranging
from temporal expression extraction and annotation to temporal reasoning and
understanding. This area of research is now a hot NLP topic and the results are
applicable to question answering, information extraction, text summarization, etc.
This paper presents the past, present and future research development in temporal
information extraction. |
