A Wordnet from the Ground Up

4.5. Hybrid Combinations 157Figure 4.10:An almost correct attachment suggested by WNW for semestr ‘semester’. Glosses: czas‘time’, okres ‘period’, rok ‘year’, półrocze ‘semester, half-year’, miesiąc ‘month’, wrzesień‘September’, październik ‘October’, grudzień ‘December’considered LU received high scores in relation to many glass dishes, but those wereoutweighed by synsets in the lower part that denote different types of bottles.The first attachment proposed for dzięcioł ‘woodpecker’ is predictable (Figure 4.13),since WNW’s precision is high for animal names. The second proposed sense mayseem to be an error but sikorka ‘tit’ is not so far from the meaning of dzięcioł ‘woodpecker’in the school jargon (someone who is believed to spend much time memorisingschool material). So, the second sense is a person, thus a distant hyponym of sikorka‘girl’. Still, what matters is probably only the accidental similarity of dzięcioł andsikorka as birds.Attachments for urna ‘urn’ presented in Figure 4.14 have been generated only basedon weak fitness (MSR RW F ) values. On average, attachment proposals computed fromweak fitness are of lower quality, but not in this case. Two proposed senses show a caseof regular polysemy characteristic for many Polish LUs in plWordNet that denote acontainer. They have a thing sense and a place sense.Two of the four attachment points (all based on weak fitness) for sztaba ‘bar (ofmetal)’ are the result of an error introduced by the TaKIPI tagger when preprocessing
