学习美国手语（ASL）的学生很难找到不熟悉的符号的含义。手语可以通过一小部分简单的特征来区分，包括手的形状、方向、位置和运动。在基于特征的ASL到英语词典中，用户通过提供查询来搜索标志，该查询是一组观察到的特征。由于符号的执行方式存在自然的变化性，并且观察容易出错，因此需要一种不同于特征精确匹配的方法。我们提出了ASL搜索，一个ASL到英语词典完全由其用户供电。ASL搜索利用潜在语义分析（LSA）的数据库的功能为基础的用户查询，以考虑到变化。为了证明ASL-Search的可行性，我们创建了ASL-Flash，这是一种学习工具，可以向ASL学生提供在线抽认卡并提供查询数据。我们对这些数据的模拟作为概念的证明，表明我们的字典的性能随着使用而提高，并且对于具有不同ASL经验水平的用户表现良好。
Students learning American Sign Language (ASL) have trouble searching for the meaning of unfamiliar signs. ASL signs can be differentiated by a small set of simple features including hand shape, orientation, location, and movement. In a feature-based ASL-to-English dictionary, users search for a sign by providing a query, which is a set of observed features. Because there is natural variability in the way signs are executed, and observations are error-prone, an approach other than exact matching of features is needed. We propose ASL-Search, an ASL-to-English dictionary entirely powered by its users. ASL-Search utilizes Latent Semantic Analysis (LSA) on a database of feature-based user queries to account for variability. To demonstrate ASL-Search's viability, we created ASL-Flash, a learning tool that presents online flashcards to ASL students and provides query data. Our simulations on this data serve as a proof of concept, demonstrating that our dictionary's performance improves with use and performs well for users with varied levels of ASL experience.
