Web sentiment analysis and CLIQUE
CLustering In QUEst (CLIQUE) is a bottom-up and grid-based clustering algorithm. The idea behind this algorithm is the Apriori feature, that is, the monotonicity of dense units with respect to dimensionality. If a set of data points, S, is a cluster in a k-dimensional projection of the space, then S is also contained in a cluster in any (k-1)-dimensional projections of this space.
The algorithm proceeds by passes. The one-dimensional dense units are produced by one pass through the data. The candidate k-dimensional units are generated using the candidate-generation procedure and the determined (k-l)-dimensional dense units that are fetched at the (k-1) pass.
The characteristics of the CLIQUE algorithm are as follows: ...
