SEMANTIC ANALYSIS

ⓘ The results of our semantic analysis are shown below using the website's language.

They are the main concepts covered by sphere-engine.com.

Each concept has a confidence score. The higher it is, the more important the topic is relative to the page.

Topics
Software development Confidence: 76% Arrow up

Software development is the process of computer programming, documenting, testing, and bug fixing involved in creating and maintaining applications and frameworks resulting in a software product.

Software development is a process of writing and maintaining the source code, but in a broader sense, it includes all that is involved between the conception of the desired software through to the final manifestation of the software, sometimes in a planned and structured process.

Therefore, software development may include research, new development, prototyping, modification, reuse, re-engineering, maintenance, or any other activities that result in software products.
Application programming interface Confidence: 76% Arrow up

In computer programming, an Application Programming Interface (API) is a set of subroutine definitions, protocols, and tools for building application software.

In general terms, it is a set of clearly defined methods of communication between various software components.

A good API makes it easier to develop a computer program by providing all the building blocks, which are then put together by the programmer.
Competitive programming Confidence: 76% Arrow up

Competitive programming is a mind sport usually held over the Internet or a local network, involving participants trying to program according to provided specifications.

Contestants are referred to as sport programmers.

Competitive programming is recognized and supported by several multinational software and Internet companies, such as Google, and Facebook.

There are several organizations who host programming competitions on a regular basis.
Compiler Confidence: 73% Arrow up

A compiler is a computer program (or a set of programs) that transforms source code written in a programming language (the source language) into another computer language (the target language), with the latter often having a binary form known as object code.

The most common reason for converting source code is to create an executable program.
Integrated development environment Confidence: 72% Arrow up

An integrated development environment (IDE) is a software application that provides comprehensive facilities to computer programmers for software development.

An IDE normally consists of a source code editor, build automation tools and a debugger.

Most modern IDEs have intelligent code completion.

Some IDEs, such as NetBeans and Eclipse, contain a compiler, interpreter, or both; others, such as SharpDevelop and Lazarus, do not.

The boundary between an integrated development environment and other parts of the broader software development environment is not well-defined.

Sometimes a version control system, or various tools to simplify the construction of a Graphical User Interface (GUI), are integrated.

Many modern IDEs also have a class browser, an object browser, and a class hierarchy diagram, for use in object-oriented software development.
