提升问答系统的精度可以从意图识别和召回优化两个角度考虑,且两者都可以用关键词表示,即从直接将用户query和知识点进行embedding转变为对两者提取关键词后再进行匹配。意图识别可以通过关键词提取(Information Extraction, IE)和槽位填充(Slot Filling,SF)实现。: ...
[38,39]. Table2shows the instruction tasks and datasets used for fine-tuning TC-Llama 2. Task selection was guided by a comprehensive review of instructional datasets and task generalization in NLP [13,40,41,42], covering information extraction (Task 3.2.1, Task 3.2.2), title generation (...
In this example, we use a subset of theDolly datasetin an instruction tuning format. The Dolly dataset contains approximately 15,000 instruction-following records for various categories, such as, question answering, summarization, and information ...
