5: <div class="original">Estado original: <span class="pos"><%= opinion.opinion %></span></div>
6: <%#= highlight(simple_format(highlight_ontology(opinion)), opinion.keywords, :highlighter => '<em>\1</em>') %>
7: <%= simple_format(highlight_ontology(opinion)) %>
8: <%= button_to_remote('POSITIVO', {:url => url_for(opinion), :method => :put, :with => '"opinion[opinion]=POSITIVE"' }, :class => :positive) %>
