Computational linguistics is an interdisciplinary field that involves computer science and natural language. It aims to solve problems related to human language with the help of computers. Computational linguistic looks at the structure and meaning of human languages, enabling machines to understand language better and make sense of it. This section covers a few concepts in computational linguistics and its scope within the context of semantics. Let’s get started!

What is computational linguistics?

Computational linguistics is the study of language from a computer science perspective. It investigates language from its theoretical foundations, and its use in practice: language in action in communication, translation, and other areas. Its goal is to help computers make sense of human languages, and make computers more useful in human activities that involve language. The term (CL) is fairly new, dating back to the late 1970s. But the idea of linguistic analysis and processing is not new at all. Medieval scholars were interested in the connections between language and logic, and many other fields of study have contributed to CL.

Semantics of language

If we break down and simplify a definition of language, it can be subdivided into two parts — syntax and semantics. If we look at a broad and generalized scope, semantics is understood to be the study of meaning, and syntax is the study of how language is formed. Syntax is the study of the rules that govern the formation of phrases and sentences. It is concerned with how words are related to one another to form phrases and sentences and how the words are ordered to achieve this. Semantics is the study of the meaning of phrases, sentences, and discourse. It is concerned with the relationships between words and phrases and how these are used to convey meaning. Syntax and semantics are two sides of the same coin, and both are critical to language study. While syntax deals with how words are formed into phrases and sentences, semantics deals with the meaning that is conveyed by the words in a sentence.

Types of meaning in language

There are multiple ways in which the semantics of language can be classified and understood. The following are the few most common ways in which the concept of semantics can be categorized. – Word meaning: Word meaning is the most obvious form of semantic analysis. The dictionary meaning of a word is widely understood as a form of word meaning. Word meaning can also be applied to words that are not included in dictionaries, such as technical terms. – Sentence meaning: The meaning of a sentence, as well as the relationship between the sentences in a discourse, is called the semantics of a sentence or the syntax of a sentence. The syntax of a given sentence is also known as its logical structure or propositional structure. – Discourse meaning: Discourse meaning is the overall understanding of a discourse. It is a combination of all the sentences in a discourse and is generally related to a topic or a theme.

Meaning computation

The process of computing the semantics of language is known as meaning computation. This is done by deriving meaning from the words in a sentence and other forms of semantics. One example is to derive the meaning of a sentence by looking for the verbs and nouns within it. For example, when we read ‘The flower is blooming in the garden’, we find that the sentence contains the verb ‘bloom’ and the noun ‘flower’. The sentence can then be understood as ‘The flower is blooming’ which means that the flower is in the process of blooming, or that the flower is currently in bloom.

Lexical Semantics

Lexical semantics is the study of the specific meaning of words in a sentence. It focuses on the relationship between a word and its meaning. This can be done formally, or informally by understanding the context in which a word is used. When a word has multiple meanings, it is called polysemous. A lexical semantic analysis is needed to see which sense of a word is most appropriate in a given context. Lexical semantics is closely linked to lexical pragmatics, lexicography, and lexicology. Lexical semantics is important in natural language processing, machine translation, and other linguistic applications that involve computers. It is also important in the construction of search engines and digital dictionaries.

Syntax and Ontology based semantics

The above sections talk about semantics as being distinct from syntax. The difference between syntax and semantics in computational linguistics is that syntax is about the relationship between words and phrases, while semantics is about the relationships between the words within the phrases. In many cases, the syntax and semantics are two different things. For example, the phrase “green is my favorite color” has the same syntax (“green”, “is”, “favorite”, “color”) but two different meanings: – Green is my favorite color: This phrase is used to declare that the color green is the favorite color of the person speaking. – Green is my favorite color: This phrase is used to describe the color of something, such as a flower, which is green.

Summary

This article covered the basics of computational linguistics and its focus on the semantics of language. It also explained the different types of meaning in language and how meaning computation is done. It concluded with a discussion of syntax and ontology based semantics and how they are different from lexical semantics. Now that you have a basic understanding of computational linguistics, you can dive deeper into the field and explore its various applications.

Computer science is a field that touches almost every other area of study. It is an interdisciplinary field that uses principles from biology, computer science, engineering, math and many more to solve problems with computers. As such, computer science students need a strong background in math. If you’re one of those people who thinks algebra class was your worst nightmare or if you find yourself struggling with the basic concepts of algebra after high school, this section will help you understand some of the key concepts in computer science. Read on for an introduction to the fundamentals of mathematics for computer science as well as links to resources that will help you brush up on your math skills before starting this exciting new degree.

Arithmetic and Calculus

Computer science relies heavily on arithmetic and calculus; these are the foundations of many other concepts in computer science. If you’re able to grasp these topics, you’ll be able to understand just about any other subject in computer science. If you find yourself struggling with these concepts, you may need to brush up on your math skills before continuing.

  • Arithmetic – Arithmetic is the basic operation of adding, subtracting, multiplying and dividing numbers. In computer science, you’ll use arithmetic to manipulate data, which is why it’s so important.
  • Calculus – Calculus is a branch of mathematics that’s used to measure change over time. In computer science, you’ll use calculus to model things like rates of change or change in the size of an object over time.

Data Structures

Data structures are the building blocks of computer science. The way you store and organize data will determine how fast your software can run, how efficient it is and how well it can handle its intended purpose.

  • Array – Arrays are two-dimensional data structures that can be used to store a list of items, like the names of students in a class or a list of restaurants that are nearby. You can search through arrays easily, and they’re flexible enough to handle a wide variety of data.
  • Linked List – A linked list is a data structure that lets you store items in a sequence, like the chapters in a book or a list of tasks to do each day. With a linked list, you can add new items to the middle of the sequence or delete items in the middle of the sequence.

Discrete Mathematics

Discrete mathematics is the branch of mathematics that deals with things that can only take discrete or specific values. For example, you could use discrete mathematics to determine the most efficient way for a person to sort a pile of papers.

  • Boolean Algebra – Boolean algebra is used to represent information in computers as either true or false. You’ll often see this in settings where you need to decide what to do based on whether a certain condition is true or false.
  • Graph Theory – Graph theory is useful in a wide variety of computer science applications, like designing algorithms and determining the best way for computers to communicate and organize data.
  • Number Theory – Number theory is used in cryptography, which is the process of turning information into an unreadable form called ciphertext that can only be deciphered by someone with a special key or code.

Probability and Statistics

Statistics is the process of collecting, analyzing and interpreting data to find trends. In computer science, you’ll use statistics to determine how likely it is that your code will be successful, how efficient it is and whether or not it can be improved.

  • Binomial Distribution – The binomial distribution lets you determine the probability that given several attempts, a given number of successes will occur. For example, if you want to know what the probability is that you’ll correctly guess all five answers in a quiz, you can plug in the number of attempts (five tries) and the number of correct answers (five successes) into the formula.
  • Central Limit Theorem – The central limit theorem is a theorem that describes how the distribution of averages will change as the sample size grows. For example, if you wanted to know the average amount of time it takes an average person to finish a marathon, you could find the sample size (how many people have completed a marathon) and plug it into the central limit theorem to determine the average time for all marathons.

Summary

The fundamentals of computer science are rooted in mathematics. If you’re struggling with arithmetic and calculus, you may want to brush up on those before starting your degree. If not, be prepared to spend a lot of time doing homework and studying. With such a heavy focus on math, you’ll need to be able to follow everything your professors say and write the code perfectly for it to work.
