NLP (Natural Language Processing) APIs

Natural Language Processing API

About natural language processing APIs

A natural language processing API is a machine learning tool that is pre-trained to do things like evaluating the tone of a given text. Other capabilities of natural language APIs include syntax analysis, entity analysis, and content classification.

An NLP API deciphers the meaning and structure of a text. Using pre-trained natural language models, developers can apply this type of comprehension to the applications they’re working on to extract information and/or better understand customer sentiment and the conversations occurring online about their product or service.

What is natural language processing?

Natural language processing is a key field that lies at the intersection of machine learning, computer science, and linguistics. NLP can trace its origins to the 1950s. At that time, although artificial intelligence was still a nascent subject of study, the famous Turing test and other experiments involving automatic translation gained traction in the scientific and academic communities.

How do natural language processing APIs work?

APIs for natural language processing work via state-of-the-art statistical machine learning. Most require just a few lines of code to run. After training the model, you can apply it to any document or web page and let the program do the heavy lifting.

Who are NLP APIs for?

Developers who want to perform machine translation, language research, news analysis, part-of-speech tagging, noun phrase extraction, document indexing, topic modeling, stemming and lemmatization, sentiment analysis, named entity recognition, or classification can benefit from these APIs.

Why are NLP APIs important?

Natural language processing allows developers to analyze and classify text-based entries at a speed and with a degree of accuracy that humans could never hope to achieve on their own. APIs are integral to the integration of this software into existing systems. Once integrated, the NLP analyses help with everything from understanding customers’ opinions and generating UX insights to cross-comparing invoices to discover the relationship between requests and proofs of payment.

What you can expect from a natural language processing API?

An NLP API will help you save time and money by performing indexing and other related tasks both quickly and efficiently.

Are there examples of free natural language processing APIs?

Open-source NLP APIs are not only free but can also easily be customized. Examples of these open-source APIs for NLP available in Python--the preferred machine learning programming language--include Natural Language Toolkit, SpaCy, Stanford CoreNLP, Gensim, and TextBlob.

Natural Language Understanding

Ambiverse Natural Language Understanding API extracts entities from unstructured text, enabling a more precise transformation of texts into actionable, measurable, and easily accessible knowledge. Entities are identified by types such as person, location, organization, or product, and linked to the Wikipedia-derived YAGO knowledge graph. You can query the knowledge graph to obtain further information about these entities, such as Wikipedia links, textual descriptions, images, and lists of relevant categories.

Topics Extraction

Topics Extraction tags locations, people, companies, dates and many other elements appearing in a text written in Spanish, English, French, Italian, Portuguese or Catalan. This detection process is carried out by combining a number of complex natural language processing techniques that allow to obtain morphological, syntactic and semantic analyses of a text and use them to identify different types of significant elements.

Text Classification

Automatic multilingual text classification according to pre-established categories defined in a model. The algorithm used combines statistic classification with rule-based filtering, which allows to obtain a high degree of precision for very different environments. Three models available: IPTC (International Press Telecommunications Council standard), EuroVocs and Corporate Reputation model. Languages covered are Spanish, English, French, Italian, Portuguese and Catalan.

Sentiment Analysis

Multilingual sentiment analysis of texts from different sources (blogs, social networks,...). Besides polarity at sentence and global level, Sentiment Analysis uses advanced natural language processing techniques to also detect the polarity associated to both entities and concepts in the text. Sentiment Analysis also gives the user the possibility of detecting the polarity of user-defined entities and concepts, making the service a flexible tool applicable to any kind of scenario. Additionally, Sentiment Analysis detects if the text processed is subjective or objective and if it contains irony marks [beta], both at global and sentence level, giving the user additional information about the reliability of the polarity obtained from the sentiment analysis.
