just one. Alternatively, structurally relevant words could be selected by applying
the PageRank algorithm to the semantic graph. With our graph, the top-10 relevant
words for poesia would be:
musa, pessoa, arte, poeta, poético, poeticamente, obra, piério, lírica, alba 7
(muse, person, art, poet, poetic, poetically, work, Pierian, lyric, alba)
With these, more diverse blocks can be generated, including:
já sobre os dantescos poetas pende
que maneiras e artes são de árduas empresas
entre pessoa e o passeante
com tantas liras e poesias inventadas
2, the poesia
subgraph would become something like Fig. 12.5 where we have omitted the higher
level relation names. It is clear that this graph is structured on words but not senses.
Therefore, there will be relations mixing different senses of polysemous words. For
instance, the word obra might either denote a work of art, thus the relation with the
bible and repertoire, or a construction, thus the relation with building. Moreover,
the graph includes figurative meanings, which explain the relations between poetry,
inspiration, muse and harmony, as well as the relation between inspiration and flame.
While this could be problematic in other tasks, we believe that it makes poetry
generation even more interesting.
With higher depths, the generated poem tends to be less focused on the domain,
as in the following, where poesia is the only seed, with
