Natural Language Generation & Processing Basics

Both Natural Language Generation and Processing have been of interest to me for the past few years. My work in the Intelligence field has shown me the value and future of where these types of technologies will shine. This article aims to help anyone like myself who is looking to leverage Natural Language Generation (NLG) and Processing (NLP) to uncover actionable insights in their data like I need to. And how I began to think of ways to leverage my data across various industries, I’m interested in. I’m going to do my best to break down their foundations. With that said, let’s dive deeper into what Natural Language Generation & Processing is all about.

Natural Language

The philosophy of natural language is a fascinating and ever-evolving field that has captivated some of the best thinkers throughout history. It seeks to explain the nature of language, its relationship with reality, and how we use it to form thoughts, ideas, and meanings. Philosophers such as Aristotle were among the earliest to examine the potential of language to convey meaning. And subsequent generations have gone on to explore how our concepts of the world are influenced by language. From theories of reference and meaning to debates about the role of language in structuring our thought processes, exploring language’s philosophy helps us gain some insight into some of humanity’s most important questions about communication and cognition.

Linguistics

What is Linguistics?

Linguistics is the scientific study of language, including its structure, and use.
It encompasses a wide range of topics and approaches, from the sounds of language (phonetics and phonology), to the meaning of words and sentences (semantics), to the social and cultural aspects of language use (sociolinguistics).

Branches of Linguistics:

Phonetics and Phonology: The study of the sounds of language and how they are used to convey meaning.
Morphology: The study of how words are formed and structured.
Syntax: The study of rules for constructing sentences and the arrangement of words and phrases.
Semantics: The study of meaning in language, including both the meaning of individual words and the meaning of sentences.
Psycholinguistics: The study of the mental processes involved in producing and understanding language.
Sociolinguistics: The study of the social and cultural aspects of language use, including language variation and change.

Why Do We Need to Understand Linguistics?

Linguistics provides a unique window into the nature of language and our ability to communicate and express our thoughts.
It helps me understand how language works, how it is acquired, and how it changes over time.
Studying linguistics can also shed light on important social and cultural issues, such as multilingualism and language discrimination.

Language Structure and Syntax

Language syntax and structure govern how words and phrases are combined. This helps us form meaningful sentences in a language. These rules determine the order of the words in a sentence, how the terms are connected, and how the meaning is conveyed.

Components of Syntax

Phrases: A group of words that work together to perform a single grammatical function within a sentence. For example, in the sentence “the cat sat on the mat,” the phrases are “the cat” and “sat on the mat.”
Clauses: A clause is a group of words that contain a subject and a verb. Clauses can be independent (standing alone as a complete sentence) or dependent (cannot stand alone as a complete sentence).
Word Order: The order of words in a sentence plays a crucial role in determining its meaning. In English, the standard word order is Subject-Verb-Object (SVO).

Structural Elements of Language

Nouns: Nouns are words that refer to people, places, things, or ideas.
Verbs: Verbs express actions, states of being, or occurrences.
Adjectives: Adjectives modify nouns or pronouns, describing their characteristics.
Adverbs: Adverbs modify verbs, adjectives, or other adverbs, specifying time, place, manner, or degree.

Syntax and Communication

A good command of syntax and structure is essential for effective communication in any language. It helps convey the intended meaning accurately and clearly. However, different languages have different syntax and structure rules, and it’s essential to understand and follow them to avoid misunderstandings and communicate effectively. Language syntax and structure are fundamental components of any language. Determining how words and phrases are combined to form meaningful sentences. Understanding the rules of syntax and structure is essential for effective communication in any language.

Language Semantics

Language semantics is a branch of linguistics that deals with meaning in language. It’s the study of how meaning is conveyed through words, phrases, sentences, and larger language discourse units.

Components of Semantics

Words and Meanings: Words have meaning and can refer to specific objects, events, or ideas. Some words have multiple meanings, and the meaning of a word can change based on the context in which it is used.
Context and Meaning: Context plays a crucial role in determining the meaning of a word or sentence. The purpose of a word can be influenced by the words that come before or after it. As well as the situation in which it is used.
Pragmatics: Pragmatics is the study of how meaning is influenced by the context in which it is used. It looks at the role of non-linguistic factors in shaping sense, such as the speaker’s intention and the listener’s expectations.

Semantics and Communication

Effective communication requires a good understanding of language semantics. When we use language, we rely on a shared understanding of the meanings of words and sentences to accurately convey our thoughts and ideas. However, misinterpretations and misunderstandings can arise when there is a lack of agreement on the meanings of words or when the context of a sentence needs to be clarified.

Semantics and Language Development

Semantics is also an essential part of language development in children. As children learn to use language, they must understand the meanings of words and how they fit into sentences. This is typically done by listening to how our parents and siblings use words and phrases. Kids must also learn how context and pragmatics influence meaning. Understanding the role of semantics in language development helps us appreciate the complexity of language acquisition and how it contributes to our ability to communicate effectively. So really, language semantics is the study of meaning in language. It concerns how meaning is conveyed through words, phrases, sentences, and larger communication units. Understanding the rules of semantics is essential for effective communication and language development.

Spoken or Speech Corpora

A speech or spoken corpora is a collection of spoken language recordings gathered for linguistic research and analysis. These recordings can include transcriptions of conversations, interviews, earnings calls, or public speeches.

Advantages of Speech Corpora

Provides a representative sample of spoken language: By studying a large selection of spoken language, researchers can better understand how people use language in real-life situations.
Facilitates research in spoken language: By analyzing spoken corpora, researchers can identify patterns and trends in the way people use language when they say, which can be used to inform linguistic theory and improve applications like speech recognition and generation.
Improves speech technologies: Spoken corpora are often used to train and enhance speech technologies, such as speech recognition and generation systems.

Popular Speech Corpora:

The Switchboard Corpus: This corpus is a collection of telephone conversations in American English, including both speech and transcriptions.

Text Corpora

A text corpora, also known as a corpus, is an extensive collection of texts that have been gathered for linguistic research and analysis. These texts can range from written works, such as books, articles, and websites, to spoken languages, such as transcriptions of conversation and speech.

Advantages of Text Corpora

Provides a representative sample of a language: Text corpora offer a way to study the language that is representative of how it is used, rather than just relying on intuition or personal experience.
Facilitates linguistic research: Researchers can identify patterns and trends that might not be noticeable through a smaller sample by studying large amounts of language data.
Improves natural language processing: Text corpora are used to train and improve natural language processing systems, such as machine translation and text classification systems.

Popular Text Corpora:
