GetVector |
No local weighting in this calculation

GetLocalWeightedVector | ||||
WordsToBasis |
Takes a string, splits on whitespace, decomposes each word to the basis, and returns the basis. It's a little
bit obfuscated for speed -- check out one of the other decomposition methods for a clearer picture of the algorithm.
|
|||
DecomposeReturnInformativity |
A generic decomposition, taking a vector to be decomposed and a basis, returning the
residual (length of the perpendicular component)
|
|||
QuickDecomposeReturnRelevance |
Decompose a word to the basis and only return relevance (cosine of vector to parallel component of projection
Don't add perpendicular component to basis
|
|||
QuickDecomposeReturnRelevanceAndInformativity |
Don't update the basis.
|
|||
DecomposeReturnRelevanceAndInformativity |
Decompose and return both cohesion values
|
|||
DecomposeDocument |
A decomposition specific to a the AbstractDocument class, which has fields for informativity
and relevance
|
|||
GetTopNMatchingDocuments |
Calculate cosine between this document and all documents in the collection
