OpenCalais

Notes:

Calais is a service by Thomson Reuters that automatically extracts semantic information from web pages and other online content. Calais uses natural language processing (NLP) and other AI technologies to analyze the text and structure of web pages, and to identify and extract semantic information, such as named entities (people, organizations, locations, etc.), events, facts, or other information that can be used on the semantic web.

The semantic web is a vision of the World Wide Web in which the meaning of web content is explicit and can be understood and processed by machines, enabling them to perform tasks such as searching, reasoning, or decision making. Calais is designed to facilitate the use of semantic web technologies by automatically extracting semantic information from web pages, and providing it in a format that can be easily integrated into semantic web applications.

Calais is a powerful and versatile tool for extracting semantic information from web pages, and it is used by a variety of organizations and industries, including media, publishing, finance, and intelligence. By automatically extracting semantic information from web pages, Calais enables users to quickly and easily access and use the meaning and insights that are hidden in online content, making it a valuable tool for a wide range of applications.

Named Entity Recognition and Disambiguation (NERD) is a natural language processing task that involves identifying and classifying named entities in text, such as people, organizations, locations, and dates. NERD systems typically use machine learning algorithms to analyze text and extract these named entities, which are then labeled with their corresponding categories (e.g., “person,” “organization,” etc.).

The Calais service by Thomson Reuters is a natural language processing platform that provides a range of tools for text analysis, including named entity recognition and disambiguation. Calais uses machine learning algorithms to analyze text and extract named entities, which are then disambiguated and linked to a structured database of entities, such as Wikipedia and other publicly available data sources. This allows Calais to provide detailed, structured information about the named entities it extracts, such as their definitions, relationships, and other relevant information. Calais can be used for a variety of applications, including information extraction, content categorization, and text analysis.
