Today I read a paper titled “The Best Trail Algorithm for Assisted Navigation of Web Sites”
The abstract is:
We present an algorithm called the Best Trail Algorithm, which helps solve the hypertext navigation problem by automating the construction of memex-like trails through the corpus.
The algorithm performs a probabilistic best-first expansion of a set of navigation trees to find relevant and compact trails.
We describe the implementation of the algorithm, scoring methods for trails, filtering algorithms and a new metric called \emph{potential gain} which measures the potential of a page for future navigation opportunities.
