Temporal entities help to estimate authorship dates, enhance information retrieval capabilities, detect and<br>track topics in news articles, and augment electronic news reader experience. Research has been performed on the<br>detection, normalization and annotation guidelines for English temporal entities. However, research for Urdu<br>language lags far behind and there is a need for lot of work to be done in this regard especially when huge quantity<br>of Urdu data is being generated on online social networks on daily basis. In this paper, we propose a rule-based<br>approach for temporal entity extraction for Urdu language. Comparing our approach with existing Urdu temporal<br>entity extraction approaches, our approach dominates on behalf of accuracy and on tackling with all types of Urdu<br>temporal entity types. We use a publicly available Urdu data corpus for our experiments which consists of 206 date<br>tags. We extend this dataset by adding 200 Urdu Fully Qualified Date (UFQD) tags. We also introduce a new date<br>type for Urdu language called Urdu Partially Fully Qualified. Our proposed system achieved average (0.97, 0.98<br>and 0.98) (Precision, Recall and F1-Measure) respectively for UFQD and Urdu Partially Fully Qualified Date.<br>Some challenges and issues of other date types in Urdu Textual Language i.e. Deictic and Anaphoric are also<br>discussed in detail.</p&gt;}, number={3}, journal={University of Sindh Journal of Information and Communication Technology }, author={Daler Ali and Malik Muhammad Saad Missen and Muhammad Ali Memon and Muhammad Ali Nizamani and Asadullah Shaikh}, year={2020}, month={Oct.}, pages={181 - 188} }
