tailieunhanh - VLSP shared task: Named entity recognition

Named Entities (NE) are phrases that contain the names of persons, organizations, locations, times and quantities, monetary values, percentages, etc. In this paper, we describe the datasets as well as the evaluation results obtained from these two campaigns. | Journal of Computer Science and Cybernetics 2018 283-294 DOI 1813-9663 34 4 13161 VLSP SHARED TASK NAMED ENTITY RECOGNITION NGUYEN THI MINH HUYEN1 NGO THE QUYEN1 VU XUAN LUONG2 TRAN MAI VU3 NGUYEN tHi THU HIEN4 1VNU University of Science 2 Vietlex 3VNU University of Engineering and Technology 4 Thai Nguyen University of Education huyenntm@ Crossref Similarity Check Powered 0 inicnllcatc Abstract. Named Entities NE are phrases that contain the names of persons organizations locations times and quantities monetary values percentages etc. Named Entity Recognition NER is the task of recognizing named entities in documents. NER is an important subtask of Information Extraction which has attracted researchers all over the world since 1990s. For Vietnamese language although there exist some research projects and publications on NER task before 2016 no systematic comparison of the performance of NER systems has been done. In 2016 the organizing committee of the VLSP workshop decided to launch the first NER shared task in order to get an objective evaluation of Vietnamese NER systems and to promote the development of high quality systems. As a result the first dataset with morpho-syntactic and NE annotations has been released for benchmarking NER systems. At VLSP 2018 the NER shared task has been organized for the second time providing a bigger dataset containing texts from various domains but without morpho-syntactic annotation. These resources are available for research purpose via the VLSP website resources. In this paper we describe the datasets as well as the evaluation results obtained from these two campaigns.
