Figure 2From: Protein annotation as term categorization in the gene ontology using word proximity networksGO node Word Expansion via proximity measure. (1) For each document, a Boolean matrix of word occurrence in paragraphs (R) is created. (2) Co-occurrence proximity network WPP is computed. (3) Words in GO node label (W GO ) are expanded (W GOProx ) using WPP. (4) Intersection of vector of expanded GO node words (W GOProx ) with word vectors for each paragraph in the document (columns of R) : paragraph with largest intersection is returned.Back to article page
