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 is you to people (team 0 in solutions) that contains many relational adjectives regarding gold standard. This is the most compact people according to clustering criterion.

Brand new discussion centers around the group analyses that have three and you may five clusters since the the basis try three kinds (intensional, qualitative, and relational) and we also imagine a total of four categories (basic kinds together with polysemous categories: intensional-qualitative and you can qualitative-relational)

Several other group (2 from inside the services A, one in provider B) has the most qualitative adjectives regarding the standard, also all of the intensional and IQ adjectives.

Adjectives that will be polysemous between an excellent qualitative and you may a good relational reading (QR) is actually strewn thanks to all of the clusters, despite the fact that inform you a propensity to end up being ascribed to the relational team when you look at the service B (cluster 0).

The 5-method results are depicted from inside the Dining table six. Into one hand, the fresh table means that the 5-method construction discover from the clustering algorithm is very just like the 3-ways framework for the Table 5. This means that the three groups into the An excellent and you can B possess generally already been replicated by the about three very first groups inside C and you can D, correspondingly. At exactly the same time https://datingranking.net/latinamericancupid-review/, the distinctions between the structures received having fun with theoretic instead of POS possess be apparent about five-method choices. On set-up of one’s check out, we’d expected you to party for every single classification, together with QR and you can IQ adjectives isolated in the a cluster of the very own. This will be certainly maybe not borne call at Desk six. Whatever you see rather would be the fact (a) brand new combined groups persist and you will get filled up with the latest clustering traditional (select clusters 0 from inside the service C and you may 0–one in service D, that have a combination of Q, QR, and you will R adjectives), and you may (b) several additional small groups are created (clusters step 3 and you will cuatro both in alternatives) and no clear translation, recommending your three-way lay-upwards fits most readily useful the dwelling bare of the clustering formula.

From the dialogue away from Dining tables 5 and you may 6 we end you to the 3-method clustering match the target classification better than the five-means clustering, which polysemous adjectives commonly recognized as yet another class. Such performance recommend that acting polysemous adjectives in terms of extra, advanced categories is not a sufficient strategy (we come back to this time then).

Remember that we defined theoretic and you can POS provides evaluate the new structures obtained having fun with technically informed and you may concept-independent have. After that feature study, not reported right here getting room explanations, suggests a top relationship amongst the extremely detailed attributes of options A good and you will B. step 3 This features the new communications between them element representations having esteem to your clustering abilities: The fresh new POS provides elicited as most discriminative because of the clustering formula was accurately individuals who correspond to the newest theoretic have. That it communications explains the newest resemblance involving the selection acquired to your two types of symbol as well as the same time frame provides support on the introduce definition of the theoretical keeps.
