An automatic reading assistance application for documents available in electronic form. An automatic annotator is provided which finds concepts of interest and keywords. The operation of the annotator is personalizable for a particular user. The annotator is also capable of improving its performance overtime by both automatic and manual feedback. The annotator is usable with any electronic document. Another available feature is a thumbnail image of all or part of a multi-page document wherein a currently displayed section of the document is highlighted in the thumbnail image. Movement of the highlighted area in the thumbnail image is then synchronized with scrolling through the document.
