4.5.2 Normal Polysemy
Our earliest series of tests offers opinions toward matter, what exactly is a sufficient computational design to have typical polysemy? Particularly, i have found that treatment of normal polysemy with regards to out-of independent classes is not enough. Understand that new determination on tests showed within part is the fresh hypothesis you to definitely polysemous adjectives exhibit a linguistic choices one gets involved in the first groups mixed up in typical polysemy, ergo producing function values that are among those of the newest basic categories (cf. Profile step 1). For this reason, we had asked that polysemous adjectives function a great homogeneous band of lexical 
points, classified accurately of the proven fact that they exhibit properties out-of for every category to some extent. Yet not, it expectation is not borne in the outcomes of your tests. To that esteem, it is hitting you to QR adjectives (polysemous anywhere between a qualitative and a beneficial relational discovering) was give throughout most of the groups in most choice. They are certainly not defined as a homogeneous classification, nor since the unlike the others. Crucially, as discussed when you look at the Section cuatro.dos, the differences between your ability philosophy out-of polysemous adjectives and the ones of your own earliest groups aren’t sufficiently strong enough so you’re able to promote an excellent independent class.
We think that reason for such show would be the fact one to polysemous adjectives do not indeed has a beneficial homogeneous, classified character: Inside the confirmed corpus, most adjectives are used mainly in another of their sensory faculties, add up to among the many basic categories, which means the latest “hard” category having around three clusters fits finest. For-instance, the new qualitative-relational adjective ironic (‘ironic’) is mainly put while the a great qualitative adjective on corpus. Having said that, militar (‘military’) is mostly put given that good relational adjective, which will be constantly assigned to among the many relational clusters inside most of the selection. Thus, in the event polysemous adjectives normally would inform you a combined conclusion, for each lexical item sometimes trend that have one of several very first classes. An option conceptualization from normal polysemy and you will experimental build is named getting, and this will become topic of one’s second area.
The fresh tests displayed in the previous part pursued several requirements: with the one hand, to check on the original classification proposition; on the other, to check a type of typical polysemy you to treats polysemous adjectives regarding separate classes. Depending on the basic goal, brand new tests contained in this section trust the results of the prior studies, and use the alternative category revealed from inside the Area step three.2. The contrary classification has in addition become supported by good clustering try not claimed right here to own area grounds (see Boleda, Badia, and you can Batlle to own facts and you will discussion).
Appropriately, they always seems from the qualitative groups
Depending on the next goal, you will find revealed that the very first model is not profitable on modeling regular polysemy. In addition, the study from element values in the last point shows that the possible lack of profits is not associated with the particular technique used in the original try out, but to your functions regarding polysemous adjectives: the point that they are utilized predominantly in one of the sensory faculties, plus the fact that this new ability withdrawals of “polysemous categories” mostly overlap which have that from might kinds.
In the current tests, we write a choice method to normal polysemy that’s founded on the direction one polysemous adjectives belong to one or more semantic group, from the construction out-of multiple-label class. A good example of a multi-title group task are Text message Categorization (Schapire and you may Artist 2000), in which a file would be discussed thru several name (e.grams., Health and Regional), therefore it efficiently falls under one or more of your target classes. The newest motivation because of it the fresh new method is that the polysemous adjectives display properties of all the kinds on it (look for Section step 3.3). The fresh new hypothesis is the fact that proof located to have a good polysemous adjective that is polysemous anywhere between, say, a great relational and you can a good qualitative use shall be strong enough getting the adjective to-be assigned to the relational therefore the qualitative categories. Observe that of the assigning the adjective on a couple categories individually, we make an enthusiastic implicit group of adjective since polysemous. The success of the newest strategy relies on perhaps the more sensory faculties is well enough depicted regarding analysis, and it will feel specifically difficult to differentiate between audio and evidence to own a given category.
