Access to up-to-date and quality information can have a significant
impact on the humanitarian relief community as they coordinate
relief efforts. In addition to data that is created and curated by
expert, there is a vast volunteer community who are empowered by the
social Web to generate community curated content on sites such as
Flickr, Del.icio.us, and Google Earth.
Combining data from experts and volunteers can facilitate the efforts
of relief agencies. In order to effectively use this data, one needs
to (1) discover relevant sources, (2) assess quality and
(3) understand their content. Fortunately, the wealth of content and
metadata, i.e., annotations in the form of tags, on the social Web, can
aid in this task of semantic discovery and quality assessment. |

The GeoNets project will develop methods to analyze social content and
metadata in order to extract concepts, including geospatial concepts
and generate semantically-rich geospatial data. GeoNets can
also increase the re-use of data by suggesting terms to improve the quality
of existing annotations. GeoNets will leverage methodologies for
ranking, personalization and quality assessment to create a
GeoNets dataspace and provide a user friendly query language. |

The methods developed by the project also apply to other fields where
information created by a lay community augments the knowledge produced by
professionals. In several scientific disciplines, including astronomy,
biology and ecology, an army of passionate amateurs is making new
observations and discoveries. GeoNets will create tools that will enable
scientists to leverage community-generated knowledge to create
up-to-date, semantically rich dataspaces. |
