Concept Recommender Service (a.k.a Xowl Semantic Service)

Ximdex Platform allow you to aggregate, edit, normalize, identify named entities, enrich content, transform, expand, retrieve, and publish data, from both structured and unstructured sources. You will be able to pull relevant information, share it, analyze it, and visualize it. See our demos at Ximdex Demo

Furthermore we have developed some clients for most popular cms platforms to consume our services. In this case for Drupal.

This client allows you to enrich your content managed into Drupal with a semantic layer using a named entity recognition service. You can test this service on-line here: Concept Recommender Demo

Usage

To use this enrichment service, log in into your Drupal CMS and click on "Add new content" link and create, for example, a new article.

On the edition page, select Full Html text format on CKeditor options. Its toolbar will change and you'll see a new button at the end of the third row, pretty similar to a book and a pencil.

Now you can write some relevant sentences and then click on the Xowl button.

After a few seconds, all the recognized entities will be highlighted with a color and a number. The color means the following:

• Red: People
• Green: Places
• Yellow: Organizations
• Light orange: Creative Works
• Blue: Other catagories

We can click on it to select the correct dbpedia entity. Now we can save and see on the text became a link to dbpedia uri that represents that entity.
