SEMANTIC ANALYSIS

The owner has associated the following topics to the website.

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

They are the main concepts covered by zkoss.org.

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

Topics
JQuery Confidence: 95% Arrow up

jQuery is a cross-platform JavaScript library designed to simplify the client-side scripting of HTML.

It is free, open-source software using the permissive MIT license.

Web analysis indicates that it is the most widely deployed JavaScript library by a large margin.

Grails (framework) Confidence: 94% Arrow up

Grails is an open source web application framework that uses the Apache Groovy programming language (which is in turn based on the Java platform).

It is intended to be a high-productivity framework by following the "coding by convention" paradigm, providing a stand-alone development environment and hiding much of the configuration detail from the developer.

Ajax (programming) Confidence: 92% Arrow up

Ajax (also AJAX; short for asynchronous JavaScript and XML) is a set of Web development techniques using many Web technologies on the client side to create asynchronous Web applications.

With Ajax, Web applications can send data to and retrieve from a server asynchronously (in the background) without interfering with the display and behavior of the existing page.

By decoupling the data interchange layer from the presentation layer, Ajax allows for Web pages, and by extension Web applications, to change content dynamically without the need to reload the entire page.

In practice, modern implementations commonly substitute JSON for XML due to the advantages of being native to JavaScript.

Web framework Confidence: 89% Arrow up

A web framework (WF) or web application framework (WAF) is a software framework that is designed to support the development of web applications including web services, web resources, and web APIs.

Web frameworks aim to automate the overhead associated with common activities performed in web development.

For example, many web frameworks provide libraries for database access, templating frameworks, and session management, and they often promote code reuse.

Although they often target development of dynamic web sites, they are also applicable to static websites.

Hibernate (framework) Confidence: 88% Arrow up

Hibernate ORM (Hibernate in short) is an object-relational mapping tool for the Java programming language.

It provides a framework for mapping an object-oriented domain model to a relational database.

Hibernate solves object-relational impedance mismatch problems by replacing direct, persistent database accesses with high-level object handling functions.
