SemaVis for E-Government:

Semavis for Open and E-Government to Support Domain-Experts and Decision Makers

SemaVis is an adaptive visualization technology for many kinds of data. This page illustrates some example of different datasets and datatypes, even more adaptation levels, visual comparison techniques, evaluation scenarios for the E-Government domains.




Interactive Open Government Textual Search (EurLex)
Searching for political documents, e.g. from debates or about decisions, can be challenging and becomes quickly boring. But by using interactive graphical visualization the user experience can have a significant grow. [more]



Open Government Data Visualization (EuroStat)
The need for getting valid information about certain topics and policy indicators is essential for setting the agenda for a new possible policy. Visualizing these valid and proved data provides a more useful instrument to gather information by comparing, associating, correlating and identifying various data, data-attributes or indicators.

Law Visualization to understand Legal Aspects and Political Acts
The SemaVis-Law Visualization allows an intuitive, but also a formally correct view from a lawyers point of view, on the code of law. With an easy to understand visual representation of the modelled data and attributes, users (e.g. layers or policy modelers) get a more efficient and effective overview of judicial aspects and can consider affecting paragraphs in their current objective.

Visual Law Editor to model Legal Aspects
The novel intuitive Visual Law Editor enables intuitively, but from the judicial point of view even a formal correct, modelling of legal concepts and the corresponding attribute definitions. With easy to understand visual representation it is possible to model the attributes. The hereby required information can be selected directly from the law ontology via a visual representation or alternatively by searching through diverse web-resources for supplementing information to ensure a valid modelling.

Simulation Model and Result Visualization for enhanced Impact Analysis
The simulation enables a virtual evaluation of policies. Therefore the statistical history of indicators is used to generate forecast based on mathematical models, in dependency of identified influencing indicators which can be addressed with a policy. A simulation tool has the advantage that the impact of a policy can be tested in a de-facto laboratory environment and evaluated to decide whether a certain change is desirable or not. However, such a simulator is only effective, if the results can intuitively and effectively analyzed in respect of the impact. In particular for this purpose SemaVis was used to provide an intuitive access to the simulation result data and also the used simulation model. [more]



Social Media Analysis & Opinion Mining
Besides valid and objective data, the investigation of subjective values is important for identifying problems and gathering information about the “social impact”. The method of choice to analyse based on ICT-tools the social impact is Social Network Analysis (SNA). SNA enables the analysis of social networks and the identification of opinion leaders by measuring and mapping the relationships and flows between people, groups, organizations and other connected information or knowledge entities. The nodes in the network are the people and groups while the links show relationships or flows between the nodes. Their interactive visual representation provides a quick comprehension of the relation of topics to influence actors or topics of general interest. Further it provides an explorative approach for navigating through such networks and gathering more knowledge about the related topics. Especially the identification of opinion leaders is important. An opinion leader is an active media user, who interprets the meaning of media messages or content for lower-end media users. Typically the opinion leader is held in high esteem by those who accept his or her opinions.

(Open) Knowledge Base Visualization
The web provides increasing and rising knowledge repositories that enables for example to validate hypothesis for experts, or explores options. The Knowledge Database stores multimedia documents and links them to campaigns and political topics, providing context related information to the user.
It enables a user to search for knowledge in different external (web) data and combines visualizations in visual cockpit metaphor for various policy tasks. A user is able to view on web-knowledge to validate for example an identified policy problem and gather related implicit information.
