Semantic Image Annotator

Motivation

The annotation - also known as "coding" in the social sciences and humanities- of documents is a central activity in the research process. In our case, the lexica pages which have to be analyzed were in image format and not avaibale in plain text. Hence, the Semantic Image Annotator was developed which allows selection and annotation of rectangular areas on images.

Features

A button "Annotate this image" will appear above images on their "File:"-page. Clicking this button will activate the "annotation mode". You are then able to draw rectangular annotations on the image. Clicking once will start the shaping mode in which you can move your mouse to create any rectangular shape. Another click stops the shaping mode and you can decide to accept or discard the rectangle you have created. If you are happy with the shape of the selected area and click OK, a Semantic Forms popup window - with a form you can adjust - will appear. You can specify the details of your annotation in that window.

SemanticWebBrowser

Motivation

In order to browse structured wiki-content and Semantic Web Resources the SemanticWebBrowser (SWB) was developed. The SWB allow to browse and compare the wiki's information with information from the Semantic Web. Main motivation was the enrichment of the data in Semantic CorA with data from other resources (e.g. bibliographic or biographic data from the German National Library).

Features

The extension allows you to browse every article in your wiki in a structured way or to start browsing from any URI. For a full list of the features refer to the official extension page at mediawiki.org.

Acknowlegdement

The development of the SemanticWebBrowser was carried out in cooperation with Benedikt Kämpgen and Semantic CorA served as a specific use case.

OfflineImportLexicon

Motivation

In order to assist researchers handling of data which in the case of Semantic CorA were lexicon pages in the form of image files, a simplified and structured import-routine was needed. So we developed an extension which supported this task and helped the researchers to import lexicon pages which are actually image files and describe them in the developed data model which is based on four entities.

Features

After succesful installation a user interface for the stuctured import is provided. Following hierarchical book's structure, OfflineImportLexicon creates wiki pages for the four man entities:

  • Book (in our specific Use Case it's Lexicon)
  • Volume
  • Article (Lemma)
  • Page as images
