Why are there sometimes ‘wrong’ words included under Themes?

As part of the Theme extraction Ipiphany uses semantic processing, which determines how related or similar the specific words or word associations are.
E.g. fix ~ resolve

However, this technology is not perfect and there are a number of challenges presented by the complexity of language:

• The same word can have multiple meanings and be used in different ways e.g. fix=repair and fix=to stick
• Words can have very broad usages – this is especially the case for verbs e.g. understand ~ remember ~ explain ~ feel ~ see
