In many cases web search engines like Google are still used for discovery of geographic base information. This can be explained by the fact that existing approaches for Geo-information retrieval still face significant challenges. Discovery in currently available Geoportals is usually restricted to text-based search based on keywords, title and abstract as well as applying spatial and temporal filters. Furthermore, user context as well as search results of other users are not incorporated. In…

This paper analyzes item-based collaborative ltering techniques and suggests that item- based algorithms provide dramatically better performance than user-based algorithms, while at the same time providing better quality than the best available userbased algorithms.

It is concluded that it will be impractical to rely only on one common ontology for resource discovery and that the approach of using human-created ontologies in combination with automatic concept space generation and associative retrieval is a powerful means to the discovery of geospatial resources.

It is explained how a hybrid system can incorporate the advantages of both methods while inheriting the disadvantages of neither, and how the particular design of the Fab architecture brings two additional benefits.
A Framework for Collaborative, Content-Based and Demographic Filtering

The types of information available to determine whether to recommend a particular page to a particular user are described and how each type of information may be used individually and an approach to combining recommendations from multiple sources are discussed.

A conceptual framework flexible enough to integrate existing domain knowledge bases and utilizes lightweight ontologies for explicit specification of domain conceptualization and maps domain concepts against related concepts defined in other formalized concepts schemas is described.
Slope One Predictors for Online Rating-Based Collaborative Filtering

Three related slope one schemes with predictors of the form f(x) = x + b are proposed with results competitive with slower memory-based schemes over the standard benchmark EachMovie and Movielens data sets while better fulfilling the desiderata of CF applications.
