Automatic Language Detection (ALD) involves classifying documents according to their language and the character encoding they use. Although the reasons for identifying a document’s language can vary, generally speaking, identification is useful to index, process, and filter documents, usually on a large scale.

For this reason, language detection is one of the more-up-and coming applications of Machine Learning (ML) and Artificial Intelligence (AI) technologies in today’s market.

Detect Language API helps you harness the power of artificial intelligence to detect languages on the fly.

Lecto Translation API

Given a text, it can be automatically classified in categories.

In Natural Language Processing there is a concept known as Sentiment Analysis. Given a movie review or a tweet, it can be automatically classified in categories. These categories can be user defined (positive, negative) or whichever classes you want.

In case of sentiment analysis, even humans cannot agree on 100% of the cases due to linguistic ambiguities like sarcasm. However state of the art sentiment analysis algorithms trained by thousands of real life examples perform on par with humans.

#### So what does our API do?
This API comes pre-trained with tens of thousands of APIs, carefully classified as positive or negative. You don't need to deal with training any model. Just call the API and go!

This API will also identify text with HTML code in it. Just send the HTML text without any worries.

#### Use Cases for Sentiment Analysis
Brands are relying heavily on analyzing social media monitoring and Sentiment Analysis API in order to measure return on investment (ROI) of their marketing efforts. You can also apply thematic analysis to determine the features on which the customers are talking about the most.
#### Key Features
- Pre-trained statistical models
- Ease of use

Sentiment Analysis API

Enterprise grade "natural language processing" (NLP) tools with a simple, yet powerful API.

### Main Functionalities
- **Tokenizer:** Segmenting text into words, punctuations marks etc. This is done by applying rules specific to each language. Each Doc consists of individual tokens, and we can iterate over them.
- **Visualizer:** Visualizing a dependency parse or named entities in a text is not only a fun NLP demo – it can also be incredibly helpful in speeding up development and debugging your code and training process.
- **Lemmatization:** Assigning the base forms of words. 
- **Similarity:** This API is used to compare two texts, and make a prediction of how similar they are. Predicting similarity is useful for building recommendation systems or flagging duplicates.
- **Named Entity Extraction:** A named entity is a “real-world object” that’s assigned a name – for example, a person, a country, a product or a book title. spaCy can recognize various types of named entities in a document, by asking the model for a prediction.
- **Language Detection:** Detects the human language of any given text

#### Key Features:
- Perform NLP tasks without complex formulas.
- Pre-trained statistical models.
- Ability perform NLP operations in 6 languages.
- Visualization capabilities.
- No background NLP know-how needed.
- Predictive modeling.

NLP API

This API features a fast and convenient way to embed this feature into your application.

Google's famed did you mean this feature is a powerful feature to guide your users for corrections easily. This API features a fast and convenient way to embed this feature in your application.

#### How does Did you Mean This Algorithm Work?
We have provided an API that you can easily embed in any of your applications. This API can be used for multiple purposes like

- Autocorrect words,
- Spelling mistakes,
- Correcting grammatical errors, etc.

When you make a search, machine learning algorithms process you’re the query and understand if there is not any (or a few) search result for it, but there is a similar word with lots of search results. Then it makes a decision to provide that more meaningful results.

When used together with NLP API it will be a powerful duo.

#### Key Features
- Pre-trained models
- Fast and efficient

"Did you Mean This?" API

Detects bad words, swear words by performing profanity check in a given text.

An advanced profanity filter based on English phonetics (how stuff sounds). It will help you identify bad/swear words in a given text. It will also apply a mask on the detected words and censor it.

#### Applications of Bad Words Detection API
The question comes to mind is that why and where would someone need this API. Well as discussed above the people all around the world are not so civilized. So you might think that you need to have some kind of filter to get away from them.

**eCommerce Websites**
If you are running an online business, then you must have an idea that bad reviews and comments have a very unpleasant impact. Our API has just solved one of your major issues.

**Online Video Games**
The point is that games are mostly played by children and there is no restriction about anything. Abusive language is widely used in online games unless you stop it.

#### Key Features
- Tells you what swears and where they are used in a message.

- Words with special characters can get caught.
- Very resistant to filter bypassing attempts.

Bad Words API

Moderate and filter user texts in real-time with our API.

#### Automatically find inappropriate words and phrases in any text
Our Text Moderation API has been designed and battle-tested on all sorts of text inputs. It is available in many languages so that you can support users from any region. Use it to moderate user messages, chats, user profiles, usernames, comments or reviews in real-time.
#### Filter any Objectionable content.
Pick and choose the filters you want to apply. No extra work or list creation needed on your end. You can use our filters straight out of the box. Whenever there is a match, our **API** gives you a tag describing the type of content found along with its position in the text, so you can easily remove the offending phrase, change it or block the entire message.
#### Prevent users from bypassing your filters
Our smart filters will work even when users actively try to circumvent them. Using **Natural Language Analysis** and **Proprietary Algorithms**, our filters are able to detect millions of variations for each unwanted word: letter replacements, character insertions, phonetic variations, leet speak, obfuscation, hyphenation, special characters, embeddings etc.
#### Key Features:
- Detect Personal Information.
- Detect links and URLs.
- Extremely fast and efficient.
