Although researchers have addressed this\nconcept for open-domain dialogs, little attention has been focused on\ntask-oriented dialogs. Furthermore, no previous studies have analyzed whether\nresponse ranking can improve the performance of existing dialog systems in real\nhuman-computer dialogs with speech recognition errors. In this paper, we\npropose a context-aware dialog response re-ranking system. Our system reranks\nresponses in two steps: (1) it calculates matching scores for each candidate\nresponse and the current dialog context; (2) it combines the matching scores\nand a probability distribution of the candidates from an existing dialog system\nfor response re-ranking. By using neural word embedding-based models and\nhandcrafted or logistic regression-based ensemble models, we have improved the\nperformance of a recently proposed end-to-end task-oriented dialog system on\nreal dialogs with speech recognition errors.","url_abs":"http://arxiv.org/abs/1811.11430v1","url_pdf":"http://arxiv.org/pdf/1811.11430v1.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"context-aware-dialog-re-ranking-for-task","repo_url":"https://github.com/jojonki/arxiv-clip","is_official":0,"mentioned_in_paper":0,"mentioned_in_github":1,"framework":"none","reach":{"status":"ok","spdx":"MIT"}}],"tasks":[{"task_slug":"re-ranking","task_name":"Re-Ranking"},{"task_slug":"speech-recognition","task_name":"Speech Recognition"},{"task_slug":"speech-recognition-1","task_name":"speech-recognition"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
