INFORMATION STORAGE AND RETRIEVAL BY ROBERT R.KORFHAGE PDF
Latent Dirichlet allocation Feature-based retrieval models view documents as vectors of values of feature functions or just features and seek the best way to combine these features into a single relevance score, typically by learning to rank methods. Feature functions are arbitrary functions of document and query, and as such can easily incorporate almost any other retrieval model as just another feature. This fact is usually represented in vector space models by the orthogonality assumption of term vectors or in probabilistic models by an independency assumption for term variables. Models with immanent term interdependencies allow a representation of interdependencies between terms. However the degree of the interdependency between two terms is defined by the model itself.
