Visual Analytics Dashboard

The webLyzard visual analytics dashboard is an advanced information exploration and retrieval interface that helps to track and analyze emerging stories across sources, regions and languages. Its various components (= views) shown in the following screenshot provide access to a comprehensive content repository. User actions in one of these views trigger an immediate update of all other views.

Portal Header

    • The search field contains the current search together with the number of matching documents (using color-coding to reflect average sentiment). Using the rectangular marker on the left, users can decide whether this current search should be shown in the trend chart as a dotted line.
    • The main menus of the dashboard include configuration, data export (which also provides access to the PDF generator for A4 reports and 16:9 slides) and advanced search.
    • Two drop-downs allow selecting the date range and content sources (news media, social media, etc.) for the analysis. The line chart previews the results over a longer time span. The time interval (default = two months) is a global setting that not only affects the trend chart, but also the content area and dynamic visualizations. The interval can be specified by choosing a “from” and “to” date, or by selecting the past [n] days, weeks or months.
    • Below, the info bar either shows context-aware help texts, or a list of the most frequent sources or named entity references to persons, organizations or locations.

Left Sidebar – Topic Definition

    • Associations. The upper left view of the dashboard displays a list keywords associated with the search term, considering the selected source(s) and time interval. The sequence of terms is determined by the degree of semantic association. Users have the following options:
      • Click on a label to activate the tooltip and either trigger (Replace) or refine (Restrict, Extend) a search, or to Exclude certain terms from the search results. This standard tooltip is available across various dashboard features, e.g. the visual analytics tools listed below. It includes a small line chart preview and list of associated keywords, and allows combining multiple searches or filtering results by metadata attribute (e.g. positive sentiment);
      • Activate or deactivate markers (= small rectangles) to select terms to be shown in the charts or use the ‘chart’ icon visible on hover left of the “Associations” header to either select the first five items or deselect all items.
    • Metadata. Underneath the associations, the left sidebar provides access to the metadata view that segments results by source, sentiment, language and country.
    • Bookmarks. This section helps to access and manage stored topics. On hover, a gear symbol appears for accessing the overlay menu to view, configure, rename or delete bookmarks, or to set email alerts.
    • Search History (can be activated via the Configuration menu). Chronologically sorted list of recent searches, showing either the search term or a bookmark label. The suffix is added in case of queries modified through the tooltip or advanced search.
    • Clipboard (activated automatically). The Associations depend on the current search. If some of them are active in the trend chart, changing the search could result in their disappearance. In such situations, the automated activation of the Clipboard section ensures continued access to these terms.

Trend Charts

    • Line, Donut and Bar Charts. Interactive charts show (i) the share of voice, a comparative measure of attention based on the relative number of mentions, (ii) the frequency of selected topics in the specified time interval, (iii) the average sentiment regarding these topics, or (iv) the level of disagreement, measuring how strongly the sentiment regarding this topic fluctuates. Setting a moving average (default = seven days) dampens the impact of short-term fluctuations and highlights longer-term trends.

Main Content Area

    • Search Results and Cross-Media Analysis. The section below the trend chart offers five main categories to explore the search results: documents, sentences, sources, entities and relations. These categories offer multiple representations, typically at least one list view and one visualization (e.g. word tree for sentences or scatter plots for entities and sources). Interactive features in the ‘document’ and ‘sentence’ views include: (i) mouse-over document preview; (ii) initial click to show an extended quote; (iii) second click to display the full text and various annotations including keywords, sentiment, content source and referenced location.

Right Sidebar – Visual Analytics Tools

    • Maps and Visual Analytics Tools. Various interactive tools help to explore the underlying knowledge base. To investigate topic associations, the dashboard provides a tag cloud (alphabetical) and a keyword graph (hierarchical). Additional visualizations include geographic maps to render the regional distribution of search results and the cluster map to show emerging stories (= sets of related documents).
    • Interactive Widget Controls. Synchronized with each other, the visualizations can be selected via the “Configuration” menu and re-positioned using drag-and-drop operations. The ‘pause’ button in the upper right corner disables dynamic updates – e.g. the automated zoom in the geographic map or the node positioning in the keyword graph. Clicking on the ‘maximize’ button increases the size of the window and adapts its content. Clicking on the ‘popup’ button opens the map in a separate browser window and allows using the system in multiple-screen configurations.
