A Wordnet from the Ground Up

44 Chapter 2. Building a Wordnet Corecooperation, supported by a more sophisticated mechanisms in the software tool (suchas locking synsets and relation links while edited, version control and so on).Several functions available in the synset perspective had been initially considereduseful in dividing broad synsets into smaller synsets when constructing the network oflexico-semantic relations. For example, one could move selected LUs from one synsetto another and join the two synsets by a relation, or move LUs between synsets. Theseoptions have been barely used at all. The linguists preferred to work on individualLUs. For example, during the editing of a synset all LUs were often deleted one byone, and new synsets including those LUs were created from scratch.When we were designing plWNApp, we paid a lot of attention to such managementissues as quality control and calculation of the amount of work every linguist performed.We assumed this typical work model: a draft version prepared by a linguist – evaluationdone by a coordinator – error correction and final version prepared by the linguist. Thepractice showed that the requested calculations were very simple, given that no morethan six linguists worked simultaneously. The mechanism of reporting errors wasunused. The coordinators preferred making corrections on their own immediately afterfinding an error, because locating errors was also quite laborious.2.5 The Final State of plWordNet CoreManual construction of the core plWordNet took a substantial portion of the project’stime (October 2005 – June 2008), but the three main activities – work on the linguisticfoundations of plWordNet, the development of the wordnet editor plWNApp, and theediting of the wordnet database – went on in parallel, at least in the first year. Thesubsequent, much shorter, phase of semi-automatic expansion – based on the technologywhich we present in the next two chapters – resulted in almost doubling the coreplWordNet to the present version plWordNet 1.0.Nouns Verbs Adjectives AllLemmasAll 6085 3237 2617 11907Monosemous 4531 2591 1913 8986Polysemous 1554 646 704 2921LUs 8544 4128 3781 16453Synsets 5280 1595 2091 8966Table 2.1: The size of the core plWordNetSection 5.2 presents the state of plWordNet 1.0 in detail.
