Algorithm 1
ReAD algorithm.
(1) Inputs: document, dictionary, list of stop and undesirable words, | decay rate η, and STM capacity | (2) For each sequential word from a document (only if is not in | list of stop words): | (2.1) Place in STM and remove word that has been in STM the longest | (2.2) Query dictionary with | (2.2.1) = items from dictionary corresponding to word | (2.3) Remove stop and undesirable words from | (2.4) For each item k in (initial activation for new item = 0) | (2.4.1) Increase item activation: = + 1 | (2.5) For each item k for whichword is not in STM anymore | (2.5.1) Decay item’s existing activation: = − 1/η | (3) Output: Select the most activated items as topics |
