Tag Cloud – Keyword Associations
Overview. The tag cloud uses dynamic transitions to adapt its content to the current search. It arranges the most relevant keywords alphabetically, uses color coding to show their positive or negative sentiment and adjusts font size according to their relative importance (= number of occurrences in the list of search results).
Display Features
Based on Scalable Vector Graphics (SVG) and synchronized with the other elements of the webLyzard dashboard, the adaptive tag cloud supports the following interactive features:
- A single click on any of the shown keywords triggers a new full text search.
- To adjust the display, users can zoom in using the scroll wheel of the mouse, or drag and pan to select a specific part of the tag cloud.
- Hovering over a document in the search result list highlights the corresponding keywords in the tag cloud to help users identify related topics at a glance.
- Maximizing the window generates a new, more detailed version of the tag cloud that uses the available screen space to show additional semantic associations with the search term.
Sentiment Calculation
The color of each term indicates its sentiment (positive = green; neutral = black; negative = red), revealing specific aspects of opinion targets (e.g., product features) and the “spin” across sources (e.g., typically balanced news media coverage compared to the very positive slant characteristic for corporate publications found on the Web sites of Fortune 1000 companies). This provides instant feedback on how the query term has been perceived by a stakeholder group in the chosen time interval.
