项目摘要

The scientific challenge for this project is to accelerate discovery and exploration of the synthetic biology design space. In particular, many parts used in synthetic biology come from or are initially tested in a simple bacteria, E. coli, but many potential applications in energy, agriculture, materials, and health require either different bacteria or higher level organisms (yeast for example). Currently, researchers use a trial-and-error approach because they cannot find reliable information about prior experiments with a given part of interest. This process simply cannot scale. Therefore, to achieve scale, a wide range of data must be harnessed to allow confidence to be determined about the likelihood of success. The quantity of data and the exponential increase in the publications generated by this field is creating a tipping point, but this data is not readily accessible to practitioners. To address this challenge, our multidisciplinary team of biological engineers, machine learning experts, data scientists, library scientists, and social scientists will build a knowledge system integrating disparate data and publication repositories in order to deliver effective and efficient access to collectively available information; doing so will enable expedited, knowledge-based synthetic biology design research.This project will develop an open and integrated synthetic biology knowledge system (SBKS) that leverages existing data repositories and publications to create a single interface that transforms the way researchers access this information. Access to up-to-date information in multiple, heterogeneous sources will be provided via a federated approach. New methods based on machine learning will be developed to automatically generate ontology annotations in order to create connections between data in various repositories and information extracted from publications. Provenance for each entity in SBKS will be tracked, and it will be utilized by new methods that are developed to assess bias and assign confidence scores to knowledge returned for each entity. An intuitive, natural-language-based interface and visualization functionality will be implemented for users to easily access and explore SBKS contents. Additionally, as ethics is necessarily a part of synthetic biology research, data from text sources related to ethical concerns in synthetic biology will also be incorporated to inform researchers about ethical debates relevant to their search queries. Finally, to test the SBKS API, a new genetic design tool, Kimera, will be developed that leverages the knowledge in SBKS to produce better designs. The proposed SBKS will accelerate discovery and innovation by enabling researchers to learn from others' past experiences and to maximize the productivity of valuable experimental time on testing designs that have a higher likelihood of working when transformed to a new organism. This research thus provides the potential for transformative research outcomes in the field of synthetic biology by leveraging data science to improve the field's epistemic culture.

该项目的科学挑战是加速发现和探索合成生物学设计空间。特别是，合成生物学中使用的许多部分来自或最初在一种简单的细菌--大肠杆菌中进行测试，但在能源、农业、材料和健康方面的许多潜在应用要么需要不同的细菌，要么需要更高水平的生物(例如酵母)。目前，研究人员使用试错法，因为他们找不到关于给定感兴趣部分的先前实验的可靠信息。这一过程根本无法扩大规模。因此，为了实现规模，必须利用广泛的数据，以确定对成功可能性的信心。这一领域产生的数据量和出版物的指数增长正在创造一个临界点，但从业者并不容易获得这些数据。为了应对这一挑战，我们由生物工程师、机器学习专家、数据科学家、图书馆科学家和社会科学家组成的多学科团队将构建一个集成不同数据和出版物存储库的知识系统，以提供对集体可用信息的有效和高效访问；这样做将使基于知识的快速合成生物学设计研究成为可能。该项目将开发一个开放和集成的合成生物学知识系统(SBKS)，它利用现有的数据存储库和出版物来创建单一界面，改变研究人员获取这些信息的方式。将通过联合方法提供对多个不同来源的最新信息的访问。将开发基于机器学习的新方法，以自动生成本体注释，以便在各种储存库中的数据和从出版物中提取的信息之间建立联系。SBKS中每个实体的出处将被跟踪，并将被开发的新方法利用，以评估偏见并为每个实体返回的知识分配置信度分数。将实现基于自然语言的直观界面和可视化功能，使用户可以轻松访问和浏览SBKS内容。此外，由于伦理必然是合成生物学研究的一部分，来自合成生物学中伦理问题的文本来源的数据也将被纳入，以向研究人员提供与他们的搜索查询相关的伦理辩论。最后，为了测试SBKS API，将开发一种新的遗传设计工具Kimera，该工具利用SBKS中的知识来产生更好的设计。拟议的SBKS将加速发现和创新，使研究人员能够学习他人过去的经验，并最大限度地提高宝贵的实验时间在测试设计上的生产率，这些设计在转化为新有机体时具有更高的工作可能性。因此，这项研究通过利用数据科学来改善该领域的认知文化，为合成生物学领域的变革性研究成果提供了潜力。更多信息请参见https://synbioks.github.io.This项目，该项目是国家科学基金会利用数据革命大创意活动的一部分，由数据革命和国家科学基金会生物科学理事会内的生物基础设施部共同支持。该奖项反映了国家科学基金会的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
