AlchemyAPI provides cloud based text analytics services to support sentiment analysis, marketing, content discovery, business intelligence, and most tasks where natural language processing is needed. An on-site capability can also be provided if needed.
The capabilities offered by AlchemyAPI go beyond those most large organizations could build in-house, and not least because the training set used to model language is 250 times larger than Wikipedia. Innovative techniques using deep learning technologies (multi-layered neural networks) also go well beyond most of the competition, and AlchemyAPI distinguishes itself by using the technology for image recognition in addition to text analytics.
The functionality is broad and includes:
Named entity recognition for identifying people, places, companies, products and other named items.
Sentiment analysis with sophisticated capabilities such as negation recognition, modifiers, document level, entity, keyword and quotation level sentiment.
Keyword extraction to identify content topics.
Concept tagging, which is capable of identifying concepts not explicitly mentioned in a document.
Relation extraction where sentences are parsed into subject, action and object.
Text categorization to identify most likely categories.
Other functionality such as author extraction, language detection and text extraction.
Alchemy API was founded in 2005 and is based in Denver Colorado. Pricing plans for the cloud based services are based on transaction per day and start with a free Starter subscription.
