For its representation on the map, the application gets the geographical location, candidates’ names, political party and some relevant topics posted in the news which are extracted from newspapers, magazines, social networks like Twitter, Facebook or even their personal web pages.

Technical Details

The application was developed according to the requirements of each one of the phases listed below:

Integration and Information Retrieval

To perform the information retrieval that’s used as the system input, it was taken about 70 RSS sources with news and information related to Colombia and the electoral process that’s currently taking place in this country.

Among those sources of information are listed the most relevant newspapers of the country, magazines, TV news, radio broadcasts, blogs, Twitter and Facebook pages of the candidates, official sites of the campaigns and governmental entities of the country.

There were created several components that are periodically extracting new news from each one of the media that publishes the information in its web site.

Search by Media

Selection, filtering and data transformation.

Because of the diversity in the RSS sources and codification methods of the existing information, it was necessary to carry out a cleaning process (filter) and transformation of the data which eases the following processes of analysis and specific data extraction.

This process makes possible to generate a unified model of information that’s stored in a repository of specific data for this system.

Analysis and Data Mining

In the information extraction knowledge generation there were made mainly 2 tasks:

• Classification of the news according to their topics:
  • A document sorting process is done over the data stored in the system following the next criterions: Political characters related to the elections, Political Parties, Main subjects that influence the electors (Education, Health, Security etc.), controversial themes that can affect the election (Corruption, vote buying, “Plan Colombia” etc.) and some other interesting subjects (Abstention, Interview among others). This data classification and word extraction process was done with the aid of some tools that allows to identify topics using a controlled vocabulary based on a specific ontology defined for the matter of interest: The 2010 Colombian elections.

Statistical Charts

• Georeferencing:
  • The georeferencing process is the process in which a geographical coordinate is assigned to each one of the existing documents in the system. To make this process it was necessary to use some of the tools resources and activities listed bellow:
    • Colombian Gazetteer Database (http://en.wikipedia.org/wiki/Gazetteer).
    • Recognition of Geographical Entities over Natural Language Processing and Artificial Intelligence techniques. For this process some lists of synonyms about geographical terms and common Colombian names were included. These kinds of lists allow solve the disambiguation issues.
      
    • Detection and correction of invalid coordinates through spatial analysis processes.
    • Assignation of states and cities for each one of the articles using Spatial Analysis techniques.
    • Coordinates Transformation using spatial analysis processes in the data base engine.

Search by State

Use and Broadcasting

For the interactive visualization and querying of information a Geographical Rich Internet Application with geographical components was developed. This application allows the interactive viewing of the news events using a map with components to discover the different news by selecting the query options related to topics, locations, dates, or general keywords.

The technologies and tools used to develop this application are listed bellow:

• Esri ArcGis Server Flex API
• Esri ArcGis Online Basemaps
• Adobe Flex 3
