Evaluation of the Maximum Entropy Method

In this subsection we present the results of our evaluation over the training and testing data of the SENSEVAL-2 Spanish lexical-sample task. This corpus was parsed using Conexor Functional Dependency Grammar parser for Spanish Tapanainen97.

The classifiers were built from the training data and evaluated over the test data. Table 7 shows which combination of groups of features works better for every POS and which work better for all words together.
