Most such methods can only detect a fixed set of predefined event classes. To extend them to detect a new class without losing the ability to detect old classes requires costly retraining of the model from scratch. Incremental learning can effectively solve this problem, but it requires abundant data of new classes. In practice, however, the lack of high-quality labeled data of new event classes makes it difficult to obtain enough data for model training. To address the above mentioned issues, we define a new task, few-shot incremental event detection, which focuses on learning to detect a new event class with limited data, while retaining the ability to detect old classes to the extent possible. We created a benchmark dataset IFSED for the few-shot incremental event detection task based on FewEvent and propose two benchmarks, IFSED-K and IFSED-KP. Experimental results show that our approach has a higher F1-score than baseline methods and is more stable.<\/jats:p>","DOI":"10.1145\/3634747","type":"journal-article","created":{"date-parts":[[2023,12,2]],"date-time":"2023-12-02T12:10:35Z","timestamp":1701519035000},"page":"1-20","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":2,"title":["Few-shot Incremental Event Detection"],"prefix":"10.1145","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0896-080X","authenticated-orcid":false,"given":"Hao","family":"Wang","sequence":"first","affiliation":[{"name":"School of Information Scienceand Technology, North China University of Technology, and CNONIX National Standard Applicationand Promotion Lab"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2723-1055","authenticated-orcid":false,"given":"Hanwen","family":"Shi","sequence":"additional","affiliation":[{"name":"School of Information Scienceand Technology, North China University of Technology, and CNONIX National Standard Applicationand Promotion Lab"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1322-2107","authenticated-orcid":false,"given":"Jianyong","family":"Duan","sequence":"additional","affiliation":[{"name":"School of Information Scienceand Technology, North China University of Technology, and CNONIX National Standard Applicationand Promotion Lab"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"320","published-online":{"date-parts":[[2024,2,8]]},"reference":[{"issue":"1","key":"e_1_3_1_2_2","first-page":"11","article-title":"A small survey on event detection using twitter","author":"Datta Debanjan","year":"2019","unstructured":"Debanjan Datta. 2019.
