3.3 Hierarchical evaluation measure

Most researchers evaluate hierarchical classification systems based on standard “flat” measures: accuracy/error and precision/recall. However, these measures are not suitable for hierarchical categorization since they do not differentiate among different kinds of misclassification errors. A widely-used hierarchical measure based on the notion of distance overcomes this problem. However, it has some drawbacks. First, it is not easily extendable to DAG hierarchies (where multiple paths between two categories can exist) and multi-label tasks. Second, it does not change with depth. Misclassification into a sibling category of a top level node and misclassification into a sibling of the node 10-level deep are considered the same type of error (distance of 2). However, an error at the 10th level seems a lot less harmful than an error at the top level.

Recently, a new measure of semantic similarity specifically designed for Gene Ontology has been introduced[3]. It takes into account the specificity of a GO term, which is estimated through its probability of usage in gene annotations. The similarity of two terms is calculated as the minimum of the probabilities of their common ancestors. Since many pairs of terms would share the same ancestor nodes and, therefore, have the same semantic similarity, this measure has little discriminative power to be used as an evaluation measure. To express the desired properties of a hierarchical evaluation measure (HM), we formulate the following requirements:

1. The measure gives credit to partially correct classification, e.g. misclassification into node $I$ when the correct category is $G$ (Figure 1) should be penalized less than misclassification into node $D$ since $I$ is in the same subgraph as $G$ and $D$ is not.
2. The measure punishes distant errors more heavily:
   1. the measure gives higher evaluation for correctly classifying one level down comparing to staying at the parent node, e.g. classification into node $E$ is better than classification into its parent $C$ since $E$ is closer to the correct category $G$;
   2. the measure gives lower evaluation for incorrectly classifying one level down comparing to staying at the parent node, e.g. classification into node $F$ is worse than classification into its parent $C$ since $F$ is farther away from $G$.

The measure punishes errors at higher levels of a hierarchy more heavily, e.g. misclassification into node I when the correct category is its sibling G is less severe than misclassification into node $C$ when the correct c

The measure punishes errors at higher levels of a hierarchy more heavily, e.g. misclassification into node I when the correct category is its sibling G is less severe than misclassification into node $C$ when the correct category is its sibling $A$.

Seeing that previous measures do not satisfy all of the requirements, we propose a new hierarchical evaluation measure. The new measure is the pair precision and recall with the following addition: each example belongs not only to its class, but also to all ancestors of the class in a hierarchical graph, except the root (we exclude the root of the graph, since all examples belong to the root by default). We call the new measures $hP$ (hierarchical precision) and $hR$ (hierarchical recall).

Formally, in the multi-label settings, for any instance ($di$, $Ci$) classified into subset $C′i$ we extend sets $Ci$ and $C′i$ with the corresponding ancestor labels: $ˆCi ={⋃ck ∈Ci Ancestors(ck)}$, $ˆC′i = {⋃ck ∈C′i Ancestors(ck)}$. Then, we calculate (micro-averaged) $hP$ and $hR$ as follows:

$$ hP =∑i | ˆCi∩ ˆC′i|∑i | ˆC′i| hR =∑i | ˆCi∩ ˆC′i|∑i | ˆCi | $$

For example, suppose an instance is classified into class $F$ while it really belongs to class $G$ (Figure 1). To calculate our hierarchical measure, we extend the set of real classes $Ci = {G}$ with all ancestors of class $G:ˆCi = {B, C, E, G}$. We also extend the set of predicted classes $C′i = {F}$ with all ancestors of class $F : ˆC′i ={C, F }$. So, class $C$ is the only correctly assigned label from the extended set: $| ˆCi ∩ ˆC′i| = 1$. There are $| ˆC′i| = 2$ assigned labels and $| ˆCi| = 4$ real classes. Therefore, we get $hP = | ˆCi ∩ ˆC′i || ˆC′i | = 12$ and $hR = | ˆCi∩ ˆC′i || ˆCi | = 14$. We also can combine the two values $hP$ and $hR$ into one hF-measure:

$$ hFβ = (β2 + 1) · hP · hR(β2 · hP + hR) , β ∈ [0, +∞) $$

In our experiments we used $β = 1$, giving precision and recall equal weights.
