Each type of data has its own unique challenges when it comes to annotation.<\/p>\r\n<h3 class=\"h5\"><a href=\"https:\/\/www.clickworker.com\/image-annotation-services\/\" rel=\"noopener\" target=\"_blank\" title=\"Image Annotation Services\">Image Annotation for Computer Vision<\/a><\/h3>\r\n<p>Image annotation involves creating bounding boxes (for object detection) and segmentation masks (for semantic and instance segmentation) to differentiate the objects of different classes. Image annotation is often used to create training <a href=\"https:\/\/www.clickworker.com\/customer-blog\/machine-learning-datasets\/\" rel=\"noopener\" target=\"_blank\" title=\"Machine Learning Datasets\">machine learning datasets<\/a> for the learning algorithms<\/p>\r\n<h3 class=\"h5\"><a href=\"https:\/\/www.clickworker.com\/ai-glossary\/text-annotation-for-machine-learning\/\" rel=\"noopener\" target=\"_blank\">Text Annotation<\/a><\/h3>\r\n<p>Text annotation is the addition of relevant information about the language data by adding labels or metadata. For example, you might add labels such as &#8220;title,&#8221; &#8220;description,&#8221; and &#8220;copyright&#8221; to text files. Text annotation can also involve sentiment annotation, which assigns labels that represent human emotions such as sad, happy, angry, positive, negative, neutral, etc. Finally, semantic annotation can add metadata, additional information, or tags to text that involves concepts and entities, such as people, places, or topics.<\/p>\r\n<p><strong>NLP for Developers: Annotating Language Data &#8211; A Video by Rasa<\/strong><\/p>\r\n<div class=\"lyte-wrapper\" title=\"NLP for Developers: Annotating Language Data | Rasa\" style=\"width:420px;max-width:100%;margin:5px;\"><div class=\"lyMe\" id=\"WYL_OqdPoWmRPBU\" itemprop=\"video\" itemscope itemtype=\"https:\/\/schema.org\/VideoObject\"><div><meta itemprop=\"thumbnailUrl\" content=\"https:\/\/www.clickworker.com\/wp-content\/plugins\/wp-youtube-lyte\/lyteCache.php?origThumbUrl=https%3A%2F%2Fi.ytimg.com%2Fvi%2FOqdPoWmRPBU%2Fhqdefault.jpg\" \/><meta itemprop=\"embedURL\" content=\"https:\/\/www.youtube.com\/embed\/OqdPoWmRPBU\" \/><meta itemprop=\"duration\" content=\"PT7M26S\" \/><meta itemprop=\"uploadDate\" content=\"2020-09-28T15:00:06Z\" \/><\/div><div id=\"lyte_OqdPoWmRPBU\" data-src=\"https:\/\/www.clickworker.com\/wp-content\/plugins\/wp-youtube-lyte\/lyteCache.php?origThumbUrl=https%3A%2F%2Fi.ytimg.com%2Fvi%2FOqdPoWmRPBU%2Fhqdefault.jpg\" class=\"pL\"><div class=\"tC\"><div class=\"tT\" itemprop=\"name\">NLP for Developers: Annotating Language Data | Rasa<\/div><\/div><div class=\"play\"><\/div><div class=\"ctrl\"><div class=\"Lctrl\"><\/div><div class=\"Rctrl\"><\/div><\/div><\/div><noscript><a href=\"https:\/\/youtu.be\/OqdPoWmRPBU\" rel=\"nofollow\"><img decoding=\"async\" src=\"https:\/\/www.clickworker.com\/wp-content\/plugins\/wp-youtube-lyte\/lyteCache.php?origThumbUrl=https%3A%2F%2Fi.ytimg.com%2Fvi%2FOqdPoWmRPBU%2F0.jpg\" alt=\"NLP for Developers: Annotating Language Data | Rasa\" width=\"420\" height=\"216\" \/><br \/>Watch this video on YouTube<\/a><\/noscript><meta itemprop=\"description\" content=\"In this video, Rasa Developer Advocate Rachael will talk about what data annotation is, why it&#039;s a necessary part of NLP development and some tips and tricks to help make annotation easier. - &quot;The CDD Playbook: Strategies for Conversation-Driven Development&quot; by Karen White, https:\/\/medium.com\/rasa-blog\/the-cdd-playbook-strategies-for-conversation-driven-development-fc14657394a6 - &quot;Handbook of Linguistic Annotation&quot; edited by Nancy Ide and James Pustejovsky, https:\/\/www.springer.com\/de\/book\/9789402408799 If you want to reach out to us, feel free to leave a message at our community forum; https:\/\/forum.rasa.com\/.\"><\/div><\/div><div class=\"lL\" style=\"max-width:100%;width:420px;margin:5px;\"><\/div>\r\n\r\n\r\n<h3 class=\"h5\"><a href=\"https:\/\/www.clickworker.com\/ai-glossary\/audio-annotation\/\" title=\"audio annotation - term explanation\">Audio Annotation<\/a><\/h3>\r\n<p>Audio annotation is the process of recording and transcribing speech, with a focus on phonetics, accents, and speaker demographics. Every use case is different; some require a very specific approach such as tagging aggressive speech indicators for emergency hotline technology applications. The term &#8220;data annotation&#8221; can refer to anything from annotating the content of an audio file to annotating a single word. Several factors affect how efficient a system is for processing information, and data annotation helps with this process by identifying them all. Non-verbal cues such as silence or background noise are also annotated in order to make algorithms more efficient.<\/p>\r\n<h3 class=\"h5\"><a href=\"https:\/\/www.clickworker.com\/ai-glossary\/video-annotation-for-machine-learning\/\" rel=\"noopener\" target=\"_blank\">Video Annotation<\/a><\/h3>\r\n<p>Video annotation is the task of labeling sections or clips to be used to identify, classify, or detect the desired objects in a virtual environment. This is done using the same techniques as image annotation like bounding boxes or semantic segmentation, but on a frame-by-frame basis. Annotation is an essential technique for computer vision tasks such as localization and object tracking. By annotating videos, we can provide valuable information that can be used to improve these tasks.<\/p>\r\n\r\n\r\n<blockquote class=rounded\r\n><p class=\"pb-3\"><strong>Tip:<\/strong><\/p>\r\n\r\n<p class=\"pb-3\">Get annotated AI training data in any quantity to optimally train your computer vision model.<br\/>Learn more about our<\/p><a href=\"https:\/\/www.clickworker.com\/image-annotation-services\/ \" class=\"btn btn-primary\" role=\"button\">Image Annotation Services<\/a><\/blockquote>\r\n\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n\r\n<section class=\"white section-space top_grey_separation_sm\">\r\n<div class=\"container\">\r\n<div class=\"row\">\r\n<div class=\"col-lg-12\">\r\n<h2 class=\"section-headline mb-4\" id=\"process\">Data Annotation Process<\/h2>\r\n<p>When it comes to machine learning (ML), data annotation is an essential part of the process. It helps to clarify and understand the input patterns so that the system can learn from them and arrive at the desired outputs. The analogy of using flashcards to teach children is a good way to understand the concept. A flashcard with the picture of an apple and the word &#8220;apple&#8221; would tell the children how an apple looks and how the word is spelled. In data annotation, the label is the information that is added to the dataset for the machine learning model to understand and learn from.<\/p>\r\n<p>The data annotation process can be time-consuming, but it is important to get it right. The more accurate the annotations are, the better the machine learning model will be able to function. As with anything else, practice makes perfect, so be sure to annotate your data as accurately as possible.<\/p>\r\n<h3>Automated data annotation and data annotated by humans<\/h3>\r\n<p>There are two main ways to annotate data: automated and human. Automated annotation is performed by machines, while human annotation is done by people. Both have their pros and cons:<\/p>\r\n<p>Automated annotation can be faster and cheaper than human annotation, but may lack accuracy. This is because machines do not always correctly identify all the features of a dataset.<\/p>\r\n<p>Human annotation is often more accurate, but also more costly. This is because humans are able to look at data in more detail and identify features that machines may miss. Additionally, human annotations can be checked for accuracy, which improves the quality of the data set overall.<\/p>\r\n<h3>How can I get started with data annotation?<\/h3>\r\n<p>The best way is to use an end-to-end toolset like Plainsight&#8217;s vision AI platform. This platform allows team collaboration, labeling instructions, dataset version control, AI-powered data annotation, and even no-code model training.<\/p>\r\n<p>Another option for data annotation is iMerit. This company combines predictive and automated annotation technology with world-class customer service.<\/p>\r\n<h3>What are some best practices for data annotation?<\/h3>\r\n<p>There are a few best practices to keep in mind when it comes to data annotation:<\/p>\r\n<ul>\r\n<li>Introducing a different data ingestion pipeline &#8211; This can help reduce the time it takes to get your data into a format that is ready for analysis.<\/li>\r\n<li>How data is stored &#8211; When you store your data in a way that makes it easy to access and use, you&#8217;ll save time and effort later on.<\/li>\r\n<li>Output format &#8211; Make sure that the output of your annotation process is in a format that is easy for you to work with.<\/li>\r\n<li>Use of a new tool &#8211; If you&#8217;re introducing a new tool into your workflow, make sure that everyone who needs to use it is adequately trained.<\/li>\r\n<li>Your workforce provider&#8217;s technology &#8211; Use the technology provided by your workforce provider to track the quality and productivity of its workers, and how they capture the data required to do it.<\/li>\r\n<\/ul>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<\/section>\r\n\r\n<section class=\"gray section-space\">\r\n<div class=\"container\">\r\n<div class=\"row\">\r\n<div class=\"col-lg-12\">\r\n<h2 class=\"section-headline mb-4\" id=\"tools\">What tools are available for data annotation?<\/h2>\r\n<p>There are a variety of tools and methods you can use. You can either develop annotation tools in-house or use a commercial tool.<\/p>\r\n<p>Developing annotation tools in-house is a good option for companies at the growth or enterprise stage. These tools can be customized with few development resources of your own. However, it&#8217;s important to create long-term processes and stack integrations that will meet your needs in terms of security and flexibility to make changes over time.<\/p>\r\n<p>A few years ago, most data annotation tools were only available via open source or by building them yourself. However, in 2018, a number of commercial data annotation tools became available. These third-party, professionally developed tools offer full-featured, complete-workflow options for data labeling.<\/p>\r\n<p>If you&#8217;re considering purchasing a data annotation tool, select one that meets the needs of your project in terms of security and flexibility.<\/p>\r\n<h3>Data annotation tool requirements<\/h3>\r\n<p>When looking for a data annotation tool, it is important to consider the following:<\/p>\r\n<ul class=\"benefitStyled\">\r\n<li>Strategic approach. That means it should be able to help with the overall annotation project and not just specific tasks.<\/li>\r\n<li>Key features. For example, it should support machine learning as well as other annotations like text, audio, and video.<\/li>\r\n<li>Secure and compliant. It must meet all security requirements and adhere to compliance regulations.<\/li>\r\n<li>Quality control and assurance mechanisms in place.
