    What is Natural Language Processing API: Top Ten APIs

    What is Natural Language Processing API: Top Ten APIs

    A Natural Language Processing API is a machine learning model. It is made with the purpose of for analyzing text and speech. NLP APIs read and understand syntax, extract entities, and evaluate meaning of text and speech.

    Natural Language Processing (NLP) come under artificial intelligence (AI). It aims to make human language understandable for machines. NLP is a combination of the powers of linguistics and computer science. This enables machines to study the rules and structure of language and create intelligent systems. These systems are able to understand text and speech. They can also analyze them and extract meanings.

    What is Natural Language Processing API used for?

    NLP helps machines in understanding the structure and meaning of human language. It is done by analyzing various aspects such as syntax, semantics, pragmatics, and morphology. Computer science converts this linguistic knowledge into rule-based machine learning algorithms. These algorithms aim on solving defined issues and perform specific tasks.

    Taking Gmail as an example, emails are automatically classified into categories. These categories are advertising, social, primary, or spam. This is possible due to an NLP task called keyword extraction. Machines read words in the subject lines and associate them with predefined tags. This enables them to learn which category e-mails should belong to.

    There are many benefits to Natural Language Processing APIs. Here are some benefits:

    • Do analysis on a large scale
    • NLP helps machines to understand and analyze large amounts of unstructured text data. This data can be social media comments, customer service tickets, online reviews, news reports, etc.
    • Automate processes in real-time
    • NLP tools can help machines organize and relay information. This is an around-the-clock effort, with little or no human interaction.
    • Customize NLP tools for your industry
    • NLP algorithms can be tailored to your needs and criteria. These criteria can be complex and industry-specific language, even sarcasm and abusive words.

    How Do Natural Language Processing APIs Work?

    1: Part of Speech Tagging (PoS)

    The technique of morphology is the first step in NLP. It is about defining the functions of individual words. Most people know a simplified form of this process where words can be defined as nouns, verbs, adverbs, or adjectives. But, determining the function of a word is difficult for a computer. This classification of words can depend on their role in a sentence. Many words have changing functions. This makes it especially difficult for machines to learn and understand.

    2: Analyze Tree Diagrams

    The second step involves the use of knowledge derived from the syntax. It helps to understand the sentence structure. Here the program uses tree diagrams to break a sentence. Examples of phrases are noun phrases, which consist of a proper noun or a noun. An article, or verb phrase, consists of a verb and a noun phrase.

    Breaking up a sentence into phrases is 'parsing' and thus result in parse trees or tree diagrams. Various languages have their own different grammar rules. This means that the phrases have different compositions. Also, the hierarchy of the different phrases varies. The grammar rules for a particular language can be programmed into a computer program by hand. Also, machines can learn them using a corpus of text to recognize and understand the structure of sentences.

    3: Semantics

    Development into the field of semantics is the third step in NLP. A word might have the same tagging and syntactic function. Still, it is possible that the word could have different possible meanings. Following is a simple example of the same:

    • Chopping carrots on the board.
    • She is the chairman of the board.

    With enough knowledge of English, we could immediately see that the first example relates to a cutting board and the second to a board. This is very difficult for a computer. It is difficult for a computer to get the knowledge necessary to decipher the nouns and their correct use.

    Top 10 Natural Language Processing APIs

    Google Cloud NLP

    The tech giant is leading technological innovation. It also leads in almost all disruptive technologies, including NLP. Google Cloud NLP comes with powerful and advanced pre-trained NLP APIs. They can be easily integrated into existing business systems. Google Cloud NLP also contains complete, useful, and accurate NLP tools.

    Google's NLP API integrates easily with Google's technology suite. This also includes Google Apps and Cloud Storage. This makes it the best option for companies leveraging the Google ecosystem. Google's AutoML makes it easier for entrepreneurs to find tools tailored to their business needs.

    MonkeyLearn

    MonkeyLearn is a powerful and robust cloud solution. It gives a user-friendly analytics solution for their business needs.
