This book takes a unique approach to information retrieval by laying down thefoundations for a modern algebra of information retrieval based on lattice theory. All major retrieval methods developed so far are described in detail – Boolean, Vector Space and probabilistic methods, but also Web retrieval algorithms like PageRank, HITS, and SALSA – and the author shows that they all can betreated elegantly in a unified formal way, using lattice theory as the one basic concept. Further, he also demonstrates that the lattice-based approach to information retrieval allows us to formulate new retrieval methods.
