“…Unfortunately, they do no report separate results for the NGD component. In very recent work García et al (2014) compare NGD with several other algorithms using direct links, but do not explore the full graph, or try to characterize links. We will see that their results are well below ours (cf.…”

Hyperlinks and other relations in Wikipedia are a extraordinary resource which is still not fully understood. In this paper we study the different types of links in Wikipedia, and contrast the use of the full graph with respect to just direct links. We apply a well-known random walk algorithm on two tasks, word relatedness and named-entity disambiguation. We show that using the full graph is more effective than just direct links by a large margin, that non-reciprocal links harm performance, and that there is no benefit from categories and infoboxes, with coherent results on both tasks. We set new state-of-the-art figures for systems based on Wikipedia links, comparable to systems exploiting several information sources and/or supervised machine learning.Our approach is open source, with instruction to reproduce results, and amenable to be integrated with complementary text-based methods.
