配额用于指定您可以使用的可计数共享资源的数量。配额由 Cloud Natural Language 等 Google Cloud 服务定义。
系统限制是无法更改的固定值。
Google Cloud 使用配额来帮助确保公平性并减少资源使用和可用性的激增。配额用于限制您的 Google Cloud 项目可使用的Google Cloud 资源的数量。配额适用于一系列资源类型，包括硬件、软件和网络组件。例如，配额可以限制对某项服务的 API 调用次数、您的项目并发使用的负载均衡器数量或者您可以创建的项目数量。配额可以防止服务过载，从而保护Google Cloud 用户社区。配额还可以帮助您管理自己的 Google Cloud 资源。
Natural Language API 接收到的内容是以文本字符串的形式提供的。Natural Language API 会将此文本处理成一系列语言单元，这些单元大致对应于不同的字词边界。所有 Natural Language API 功能（情感分析、实体提取和句法分析）均使用这些语言单元作为基本要素来对提供的文本进行分析。

Quotas are defined by Google Cloud services such as Cloud Natural Language.\n- *System limits* are fixed values that cannot be changed.\n\nGoogle Cloud uses quotas to help ensure fairness and reduce\nspikes in resource use and availability. A quota restricts how much of a\nGoogle Cloud resource your Google Cloud project can use. Quotas\napply to a range of resource types, including hardware, software, and network\ncomponents. For example, quotas can restrict the number of API calls to a\nservice, the number of load balancers used concurrently by your project, or the\nnumber of projects that you can create. Quotas protect the community of\nGoogle Cloud users by preventing the overloading of services. Quotas also\nhelp you to manage your own Google Cloud resources.\n\nThe Cloud Quotas system does the following:\n\n- Monitors your consumption of Google Cloud products and services\n- Restricts your consumption of those resources\n- Provides a way to [request changes to the quota value](/docs/quotas/help/request_increase) and [automate quota adjustments](/docs/quotas/quota-adjuster)\n\nIn most cases, when you attempt to consume more of a resource than its quota\nallows, the system blocks access to the resource, and the task that\nyou're trying to perform fails.\n\nQuotas generally apply at the Google Cloud project\nlevel. Your use of a resource in one project doesn't affect\nyour available quota in another project. Within a Google Cloud project, quotas\nare shared across all applications and IP addresses.\n\nTo adjust most quotas, use the Google Cloud console.\nFor more information, see\n[Request a quota adjustment](/docs/quotas/help/request_increase).\n\n\nThere are also *system limits* on Natural Language resources.\nSystem limits can't be changed.\n\nLanguage restrictions\n---------------------\n\nThe Natural Language API currently supports only the languages listed in\n[Language Support](/natural-language/docs/languages).\n\nContent quotas\n--------------\n\nContent to the Natural Language API is provided as a text string. The Natural\nLanguage API processes this text into a series of *tokens*, which roughly\ncorrespond to word boundaries. All Natural Language API features (Sentiment\nAnalysis, Entity Extraction, and Syntactic Analysis) use these tokens as the\nbuilding blocks for performing analysis on the provided text.\n\nThe API contains the following quotas on the size of this content for each\nrequest:\n\nAttempting to process content in excess of the Text Content quota will produce\nan error. Attempting to process tokens in excess of the Token Quota will not\nproduce an error, but any tokens over that quota will be ignored.\n\nNote that byte counts may not reflect character counts, depending on the\nencoding used within the text content.\n\n\\* The Entity Mentions quota includes not only returned mentions within the\ndocument, but any noun references to those entities, **including pronouns** .\nNote that those pronouns are not returned directly in the `mentions` field,\nthough they do count against the quota.\n\nRate quotas\n-----------\n\nThe current API usage quotas for the Cloud Natural Language API are as follows\n(and are subject to change):"]]
