III-CXT-Large: Collaborative Research: Interactive and intelligent searching of biological images by query and network navigation with learning capabilities

生物学中的一个基本而困难的问题是生物体的鉴定。这项提案侧重于线虫的鉴定，线虫的鉴定特别困难，平均鉴定需要相当长的时间和高水平的专业知识。线虫对人类、其他动物和农业都有直接和重大的影响。四种线虫寄生虫感染着全世界超过20亿人，其中一种线虫造成的损失占全球所有大豆病原体估计年产量损失的三分之一。目前识别的限制因素是缺乏工具和自动化、需要离线图像比较以及需要大量的专业知识。为了使经验丰富的研究人员和学生能够使用资源，该团队将建立在图像搜索工作的基础上，使用一组图像，使识别线虫成为一个简单的点击过程。除了通过利用专家的数据和经验进行研究外，这项工作还可能使生物学更容易获得。该团队将建造一个计算机辅助的交互式导航器，它将智能地帮助用户并向用户学习。这项工作可以扩展到许多其他生物数据集。研究挑战包括特征和相似性函数的提取，以及图像和非图像数据的挖掘、聚类和异常检测。研究生参与了这项研究，还计划向高中生进行推广。

A fundamental and hard question in biology is identification of organisms. This proposal focuses on identification of nematodes, which are particularly difficult to identify, with the average identification requiring significant time and high level of expertise. Nematodes have direct and significant effect on humans, other animals, and agriculture. Four species of nematode parasites infect over 2 billion people worldwide, and one type of nematode causes one-third of the total estimated worldwide annual yield losses to all soybean pathogens. The current limiting factors for identification are the lack of tools and automation, the need for image comparison off-line and a need for significant expertise. To enable seasoned researchers as well as students to use resources, the team will build on image searching work, using a set of images that will make nematode identification a simple process of point and click. In addition to enabling research by harnessing data and experience of experts, the work may make biology more accessible. The team will build a computer-assisted interactive navigator that will intelligently assist and learn from the user. The work can be extended to many other biological data sets. The research challenges include extraction of features and similarity functions, and the mining, clustering, and anomaly detection for image and non-image data. Graduate students are engaged in the research and outreach involving high school students is also planned.
