Sentiment annotationĮmotional intelligence is one of the most difficult fields of machine learning.
Sentiment annotation: The classification of text based on the emotion, opinion or sentiment within the text.īecause text classification is a broad category, various annotation types like product categorization or sentiment annotation are technically just specialized forms of text classification. The annotators would then choose from a list of departments or categories that the client has provided. Sometimes annotators are shown product descriptions, product images or both. Product categorization: Crucial for eCommerce sites, product categorization is the sorting of products or services into intuitive classes and categories to help improve search relevance and user experience. Document classification: The classification of documents used to help with the sorting and recall of text-based content. Whereas entity annotation is the labeling of individual words or phrases, text classification is the process of annotating of an entire body or line of text with a single label. Related text annotation types include: Annotators must analyze the content, discern the subject, intent and sentiment within it and classify it based on a predetermined list of categories. Text classificationĪlso known as text categorization or document classification, text classification tasks annotators with reading a body of text or short lines of text. Annotators are tasked with linking labeled entities within a text to a URL that contains more information about the entity. Entity disambiguation: The process of linking named entities to knowledge databases about them.Įntity linking is used to both improve search functions and user experience. End-to-end entity linking: The joint process of first analyzing and annotating entities within a text (named entity recognition) and engaging in entity disambiguation. Whereas entity annotation is the location and annotation of certain entities within a text, entity linking is the process of connecting those entities to larger repositories of data about them. Types of entity linking include: 
To help NLP models learn about named entities further, entity annotation is often paired with entity linking. In this task, annotators read the text thoroughly, locate the target entities, highlight them on the annotation platform and choose from a predetermined list of labels.

Part-of-speech (POS) tagging: The discernment and annotation of the functional elements of speech (adjectives, nouns, adverbs, verbs, etc.).Įntity annotation teaches NLP models how to identify parts of speech, named entities and keyphrases within a text.Keyphrase tagging: The location and labeling of keywords or keyphrases in text data.Named entity recognition (NER): The annotation of entities with proper names.It is the act of locating, extracting and tagging entities in text. Entity annotationĮntity annotation is one of the most important processes in the generation of chatbot training datasets and other NLP training data. For developers looking to build text datasets, here is a brief introduction to five common types of text annotation. To train NLP algorithms, large annotated text datasets are required and every project has different requirements. However, none of these amazing technologies would be possible without text annotation and the companies that provide these annotation services. Recent breakthroughs in NLP have even shown potential to help the speech impaired communicate freely with automatic speech recognition devices and the people around them.
Numerous NLP solutions like chatbots, automatic speech recognition and sentiment analysis programs improve efficiency and productivity in countless businesses around the world. Natural language processing (NLP) is one of the biggest fields of AI development.
