RTE6 - Ablation Tests

The following table lists the results of the ablation tests submitted by participants to RTE6 .
The exploratory effort started in RTE5 as a mandatory track, was not only reiterated in RTE6, but also extended to tools. The first column contains the specific resources which have been ablated.
The second column lists the Team Run in the form [name_of_the_Team][number_of_the_submitted_run].[submission_task] (e.g. BIU1.2way, Boeing3.3way).
The third column presents the normalized difference between the accuracy of the complete system run and the accuracy of the ablation run (i.e. the output of the complete system without the ablated resource), showing the impact of the resource on the performance of the system.
The fourth column contains a brief description of the specific usage of the resource. It is based on the information provided both in the "readme" files submitted together with the ablation tests and in the system reports published in the RTE6 proceedings.
If the ablated resource is highlighted in yellow, it is a tool, otherwise is a knowledge resource.

Participants are kindly invited to check if all the inserted information is correct and complete.

Ablated Component	Ablation Run	Resource impact - F1	Resource Usage Description
WordNet	BIU1_abl-1	0.9	No Word-Net. On Dev set: 39.18% (compared to 40.73% when WN is used)
CatVar	BIU1_abl-2	0.63	No CatVar. On Dev set achieved about 40.20% (compared to 40.73% when CatVar is used)
Coreference resolver	BIU1_abl-3	-0.88	No coreference resolver On Dev set 41.62% (Compared to 40.73% when Coreference resolver is used). This ablation test is an unusual ablation test, since it shows that the co-reference resolution component has a negative impact.

WordNet	JU_CSE_TAC1_abl-1	13.29	The Run-1 is based on the composition of lexical based RTE methods and Syntactic RTE Method. The lexical based RTE methods are: WordNet based unigram match, bigram match, longest common sub-sequence, skip-gram and stemming. Here we ablated the WordNet based unigram match only.
WordNet	JU_CSE_TAC2_abl-1	10.19	The Run-2 is based on the composition of lexical based RTE methods, Syntactic RTE Method, Chunk and Named Entity Methods. The lexical based RTE methods are: WordNet based unigram match, bigram match, longest common sub-sequence, skip-gram and stemming. Here we ablated the WordNet based unigram match only.
WordNet	JU_CSE_TAC3_abl-1	3.86	The Run-3 is based on the Support Vector Machine that uses twenty five features for lexical similarity, the output tag from a rule based syntactic two-way TE system as feature, and output from a rule based Chunk Module and Named Entity Module. The important lexical features that are used in the present system are: WordNet based unigram match, bigram match, longest common sub-sequence, skip-gram, stemming and lexical distance (17 features). Here we ablated the WordNet based unigram match only.
