Search engines and conversational assistants are commonly used to help users complete their every day tasks such as booking travel, cooking, etc. While there are some existing datasets that can be used for this purpose, their coverage is limited to very few domains. In this paper, we propose a novel knowledge base, 'Task2KB', which is constructed using data crawled from WikiHow, an online knowledge resource offering instructional articles on a wide range of tasks. Task2KB encapsulates various types of task-related information and attributes, such as requirements, detailed step description, and available methods to complete tasks. Due to its higher coverage compared to existing related knowledge graphs, Task2KB can be highly useful in the development of general purpose task completion assistants

翻译：搜索引擎和对话助手常被用于帮助用户完成日常任务，如预订旅行、烹饪等。尽管存在一些可用于此目的的现有数据集，但其覆盖范围仅限于极少数领域。本文提出一种新型知识库"Task2KB"，该知识库利用从WikiHow（一个提供各类任务操作指南文章的在线知识资源）爬取的数据构建而成。Task2KB封装了多种类型的任务相关信息与属性，包括需求、详细步骤描述以及完成任务的可用方法。由于相较于现有相关知识图谱具有更高的覆盖面，Task2KB在通用型任务完成助手的开发中将发挥重要作用。
