The contingency tables of the clustering results with three clusters are depicted in Table 5. Part A of the table depicts the solution obtained with theoretical features, while Part B represents the solution obtained with POS features. Rows are gold standard classes and columns are clusters, labeled with the cluster number provided by the algorithm. The ordering of the cluster numbers corresponds to the quality of the cluster, measured in terms of the clustering criterion (see Equation (2)), 0 representing the cluster with the highest quality. In each cell Cij of Table 5, the number of adjectives of class i that are assigned to cluster j by the algorithm is given. The largest value for each class is highlighted (see gray cells).

First model: Three-way solution contingency tables for theoretical and POS features. Rows are gold standard classes, columns are clusters. Row TotalGS shows the number of Gold Standard lemmata and row Totalcl the total number of lemmata contained in each cluster. Note that the column labeled Total represents the row sum for each part (as the number of items per class is identical).

There was you to definitely team (cluster 0 in solutions) which has had more relational adjectives regarding the gold standard. This is the most lightweight group with respect to the clustering requirement.

The new conversation focuses primarily on the new people analyses with about three and five groups because the all of our basis is around three classes (intensional, qualitative, and relational) therefore thought all in all, four groups (earliest classes along with polysemous kinds: intensional-qualitative and you may qualitative-relational)

Another group (2 when you look at the solution A good, one in provider B) has the greater part of qualitative adjectives on gold standard, along with all of the intensional and you will IQ adjectives.

Adjectives which can be polysemous anywhere between a qualitative and you can a good relational understanding (QR) try scattered thanks to most of the clusters, despite the fact that tell you a propensity to become ascribed for the relational class into the solution B (class 0).

The 5-way email address details are portrayed for the Dining table 6. With the one hand, the brand new desk means that the 5-way design receive by the clustering algorithm is really like the 3-ways build within the Desk 5. Consequently the three groups for the A and B possess fundamentally become duplicated from the about three first groups inside the C and you can D, correspondingly. As well, the distinctions between your structures obtained using theoretic in the place of POS has much more apparent regarding four-method choices. On set-up of one’s experiment, we had requested you to definitely class for each category, in addition to QR and you can IQ adjectives isolated when you look at the a group of their very own. This might be clearly not borne in Dining table 6. Everything we find rather is that (a) the fresh combined groups persist and score filled up with the fresh clustering traditional (look for groups 0 from inside the provider C and you may 0–1 in provider D, that have a variety of Q, QR, and you may Roentgen adjectives), and you can (b) several additional brief groups were created (clusters 3 and 4 in alternatives) with no clear interpretation, indicating that the around three-ways set-right up suits greatest the dwelling exposed by the clustering formula.

Regarding the discussion away from Tables 5 and 6 i ending one to the 3-means clustering matches the target category a lot better than the five-ways clustering, hence polysemous adjectives are not recognized as another type of group. These types of overall performance suggest that acting polysemous adjectives regarding most, state-of-the-art classes isn’t an acceptable means (i come back to this time after that).

Bear in mind that we outlined theoretical and POS have to compare new formations acquired using commercially told and you may idea-independent enjoys. Next element data, maybe not reported right here to possess room explanations, reveals a high relationship within very descriptive popular features of choice A beneficial and B. 3 It shows the newest communications among them function representations which have admiration towards the clustering efficiency: The POS have elicited because so many discriminative by the clustering formula is actually correctly individuals who match the new theoretic has. That it correspondence explains the brand new resemblance involving the choice acquired into the 2 kinds lumen coupon of signal and also at the same time frame provides help towards present definition of the latest theoretic features.
