Annotate.js (coffeescript)

Introduction

Annotate.js is the frontend widget for entity recognition back-end engines like Stanbol.

Features

• Text-Enhancement support
• Spell-checker - like interaction with annotation enhancements
• Write RDFa into your content
• Independent of any editor
• One-line integration
• Configurable Enhancement types

Methods

• 'enable' gets enhancements from backend and visualizes them on the analized dom element.
• 'disable' hides all the text enhancements that are not accepted by the user.
• 'acceptAll' goes through all text enhancements and accepts the best candidate automatically.

Goals

• Provide Text enhancement directly in your content

• Provide another open source (MIT license), flexibly usable, easy to integrate tool for (semi-)automatic and manual semantic enhancement.

• A tool that's fun to integrate

    var stanbolConnector = new StanbolConnector({
        "enhancer_url" : "http://example.com/engines/",
        "entityhub_url" : "http://example.com/entityhub/"
    });
    $('#content').annotate({
        connector: stanbolConnector
    });
  

Future features

• Manual annotation - loosely coupled wysiwyg-editor enhancement?, needs selection-support
• Connection to VIE - loosely coupled, easy integration
• Clean up decoupling from the stanbol backend - schema mapping
• Entity preview using client-side templating
• Edit relationships

Dependencies

• jQuery 1.5
• jQuery UI 1.9m5
• Backbone.js
• a wysiwyg-editor with save() (here: hallo editor)
• VIE, VIE^2 (optional)

Development guide

The widget development is done in CoffeeScript. Use the following command to automatically compile the script in the background whenever it's edited:

$ coffee -c -w -o lib src/*.coffee

Apache ProxyPass settings

In order to use annotate.js on a different site other than where your stanbol instance is running you'll need a proxy for avoiding cross-site scripting. One way of doing this is to set up your server to redirect requests e.g. going to http://yoursite.com/stanbol/abc to http://stanbolsite.com:8080/abc. On an apache server this could be done with the following configuration snippet put e.g. in /etc/apache2/conf.d/stanbol. (You'll also have to enable apache proxy modules) You can use the dev.iks-project.eu:8080 stanbol instance for testing or replace the address with another stanbol installation your apache server has access to.

<Proxy http://dev.iks-project.eu:8080>
    Order Allow,Deny
    Allow from all
</Proxy>
ProxyPass /stanbol http://dev.iks-project.eu:8080
ProxyPassReverse /stanbol http://dev.iks-project.eu:8080
