The following table lists the results of the ablation tests submitted by participants, which have been introduced as a mandatory track in the RTE5 campaign.<br><br>
 +
The first column contains the specific resources which have been ablated.<br>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).<br>The third and fourth columns present 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 third refers to the score obtained in the 2-way task, the fourth to that obtained in the 3-way task. For all the runs submitted as 3-way, also the 2-way derived accuracy has been calculated.<br>
 +
Finally, the fifth 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 RTE5 proceedings.<br><br>
 +
 +
Participants are kindly invited to check if all the inserted information is correct and complete.

Latest revision as of 05:18, 25 June 2012

The following table lists the results of the ablation tests submitted by participants, which have been introduced as a mandatory track in the RTE5 campaign.

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 and fourth columns present 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 third refers to the score obtained in the 2-way task, the fourth to that obtained in the 3-way task. For all the runs submitted as 3-way, also the 2-way derived accuracy has been calculated.
Finally, the fifth 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 RTE5 proceedings.

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


Ablated Resource Team Run[1] Resource impact - 2way Resource impact - 3way Resource Usage Description

NEGATION_rules by UAIC UAIC20091.3way 0 -1.34 Negation rules check in the dependency trees on verbs descending branches to see if some categories of words that change the meaning are found.
NER (RASP Parser nertag) JU_CSE_TAC1.2way 0 Named Entity match: measure based on the number of Nes in the hypothesis that match in the corresponding text. For named entity recognition, the RASP Parser (Briscoe et al., 2006) nertag component has been used.
