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’s that group (people 0 in options) that has had many relational adjectives on the standard. This is basically the really lightweight cluster according to clustering traditional.
The newest dialogue centers on the brand new class analyses which have about three and five clusters since the all of our basis is actually three kinds (intensional, qualitative, and you will relational) and we envision a total of five categories (earliest classes as well as polysemous groups: intensional-qualitative and you can qualitative-relational)
Another cluster (2 inside solution A great, 1 in provider B) contains the most qualitative adjectives regarding gold standard, and additionally all intensional and you can IQ adjectives.
Adjectives that are polysemous between an effective qualitative and you will a good relational training (QR) was strewn thanks to most of the clusters, while they tell you a tendency to be ascribed to the relational group inside the service B (cluster 0).
The five-way results are portrayed during the Table six. To the one korean cupid hand, new dining table implies that the five-way design found of the clustering formula is extremely the same as the three-method build for the Dining table 5. Thus the three clusters during the A and you may B keeps essentially started replicated because of the around three very first groups in the C and you can D, correspondingly. In addition, the differences within formations gotten using theoretical in the place of POS has are more apparent on four-way choices. Regarding the put-up of your own try out, we’d asked you to definitely group for every group, and QR and you will IQ adjectives remote during the a group of its own. It is clearly maybe not borne in Dining table six. That which we find rather is that (a) the brand new combined clusters persevere and get high in brand new clustering requirement (come across groups 0 inside the provider C and you can 0–one in solution D, with a mixture of Q, QR, and you can R adjectives), and you may (b) one or two extra brief clusters are available (groups 3 and you may cuatro both in choices) and no obvious translation, suggesting that the three-means put-up fits most readily useful the dwelling exposed because of the clustering formula.
On conversation out-of Tables 5 and you may 6 i finish one to the three-method clustering fits the goal class better than the five-means clustering, hence polysemous adjectives commonly identified as an alternate group. These types of results advise that modeling polysemous adjectives with regards to more, advanced classes is not an acceptable means (i come back to this aspect after that).
Remember we outlined theoretic and POS enjoys evaluate the fresh structures gotten playing with commercially told and you may theory-separate has. Further ability study, perhaps not said here to possess area grounds, reveals a premier relationship between your extremely detailed options that come with solutions A great and you can B. step three Which features the fresh correspondence between them feature representations having esteem on the clustering abilities: The brand new POS possess elicited because so many discriminative by clustering algorithm is precisely people who match the theoretic provides. It telecommunications shows you the fresh new resemblance amongst the possibilities acquired into two types of representation as well as the same time will bring help toward introduce definition of the new theoretic provides.
