Cross-Media Analysis

Comparative analyses of patterns and trends across sources shed light on the editorial position of news media, and the diverging perceptions of e.g. corporations and social media users. The webLyzard cross-media analysis package consists of three major components: source selector, source list and source map.

Source Selector. Enables users to retrieve and visualize information from a specific stakeholder group or set of media channels, using the “Content Source” menu of the main header to select and deselect sources at any time during the analysis.

Source List. Accessible via the sidebar menu of the search results window, this summary table lists the number of term occurrences by source. The table offers an aggregated view that groups the results by source category (e.g. news versus social media), and a detailed view to compare Web sites such as Forbes or the Guardian, or individual social media accounts. source-list-bigdata The Source List helps identify the most critical and positive voices, as well as source-specific keywords that reflect what each source associates with the query term. The list can be sorted by name, frequency of mentions (count), reach based on the Alexa traffic rank, impact (frequency multiplied by impact), or average sentiment.

Source Map. This interactive scatter plot translates the table of the Source List into visual form, showing the relative importance of a given topic, and the editorial position of the various sources towards this topic. The data points of the scatter plot reflect the following source characteristics:

  • topic frequency (horizontal axis),
  • average sentiment towards the topic (vertical axis, color-coding), and
  • reach of the source (size of the marker).

Data point labels can be activated via the sidebar menu on the left. Whenever a user triggers a new search, animated transitions show the resulting changes in the data point distribution. source-map-tooltip
