SEMANTIC ANALYSIS

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

They are the main concepts covered by vertx.io.

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

Topics
Java virtual machine Confidence: 81% Arrow up

A Java virtual machine (JVM) is an abstract computing machine that enables a computer to run a Java program.

There are three notions of the JVM: specification, implementation, and instance.

The specification is a document that formally describes what is required of a JVM implementation.

Having a single specification ensures all implementations are interoperable.

A JVM implementation is a computer program that meets the requirements of the JVM specification.

An instance of a JVM is an implementation running in a process that executes a computer program compiled into Java bytecode.

Eclipse (software) Confidence: 78% Arrow up

Eclipse is an integrated development environment (IDE) used in computer programming, and is the most widely used Java IDE.

It contains a base workspace and an extensible plug-in system for customizing the environment.

Eclipse is written mostly in Java and its primary use is for developing Java applications, but it may also be used to develop applications in other programming languages via plug-ins, including: Ada, ABAP, C, C++, COBOL, D, Fortran, Haskell, JavaScript, Julia, Lasso, Lua, NATURAL, Perl, PHP, Prolog, Python, R, Ruby (including Ruby on Rails framework), Rust, Scala, Clojure, Groovy, Scheme, and Erlang.

It can also be used to develop documents with LaTeX (via a TeXlipse plug-in) and packages for the software Mathematica.

Development environments include the Eclipse Java development tools (JDT) for Java and Scala, Eclipse CDT for C/C++, and Eclipse PDT for PHP, among others.

Programming tool Confidence: 75% Arrow up

A programming tool or software development tool is a computer program that software developers use to create, debug, maintain, or otherwise support other programs and applications.

The term usually refers to relatively simple programs, that can be combined together to accomplish a task, much as one might use multiple hand tools to fix a physical object.

The ability to use a variety of tools productively is one hallmark of a skilled software engineer.

Application software Confidence: 71% Arrow up

An application program (app or application for short) is a computer program designed to perform a group of coordinated functions, tasks, or activities for the benefit of the user.

Examples of an application include a word processor, a spreadsheet, an accounting application, a web browser, a media player, an aeronautical flight simulator, a console game or a photo editor.

The collective noun application software refers to all applications collectively.

This contrasts with system software, which is mainly involved with running the computer.

Reactive programming Confidence: 70% Arrow up

In computing, reactive programming is an asynchronous programming paradigm oriented around data streams and the propagation of change.

This means that it should be possible to express static (e.g. arrays) or dynamic (e.g. event emitters) data streams with ease in the programming languages used, and that the underlying execution model will automatically propagate the changes through the data flow.
