Multi-level Association Graphs - A New Graph-Based Model for Information Retrieval
Hans Friedrich Witschel · 2007
This paper introduces multi-level associa-tion graphs (MLAGs), a new graph-based framework for information retrieval (IR). The goal of that framework is twofold: First, it is meant to be a meta model of IR, i.e. it subsumes various IR models under one common representation. Sec-ond, it allows to model different forms of search, such as feedback, associative re-trieval and browsing at the same time. It is shown how the new integrated model gives insights and stimulates new ideas for IR algorithms. One of these new ideas is presented and evaluated, yielding promis-ing experimental results. 1
