WordNet - RTE Users

Given the high number of WordNet users, the table has been splitted into two: the first containing the users of the last campaign, the second containing the users of previous campaigns.

RTE5 Users

Participants*	Campaign	Version	Specific usage description	Evaluations / Comments
AUEB	RTE5		During the calculation of the similarity measures we treat words from T and H that are synonyms according to WordNet as identical.	Ablation test performed. Negative impact of the resource: -2% accuracy on two-way, -2.67% on three-way task.
BIU	RTE5	3.0	Synonyms, hyponyms (2 levels away from the original term), the hyponym_instance relation and derivations.	Ablation test performed. Positive impact of the resource: +2.5% accuracy on two-way task.
Boeing	RTE5		The system makes uses of Wordnet synonyms, hypernyms relationships between (senses of) words, "similar" (SIM), "pertains" (PER), and "derivational" (DER) links to recognize equivalence between T and H.	Ablation test performed. Positive impact of the resource: +4% accuracy on two-way, +5.67% on three-way task.
DFKI	RTE5		FIRST USE: Argument alignment between T and H. SECOND USE: used to change all the nominal predicates into verbs, to calculate relatedness between T and H (using VerbOcean).	FIRST USE: Ablation test performed. Impact of the resource: -0.17% accuracy/null respectively on two-way and three-way task for run1; +0.16%/+0.34% for run2; +0.17%/+0.17% for run3. SECOND USE (WordNet+VerbOcean): null/+0.17% accuracy respectively on two-way and three-way task for run1; +0.5%/+0.67% for run2; +0.17%/+0.17% for run3.
DirRelCond	RTE5		Use of many WordNet relations (such as synonymy, hypernymy, hyponymy, meronymy, holonymy etc.) to compute the relatedness between words with the same part of speech in T and H.	No ablation test performed. The resource cannot be removed without breaking the functionality of the system.
DLSIUAES	RTE5		FIRST USE: Similarity between lemmata, computed by WordNet-based metrics. SECOND USE: antonymy relations between verbs. THIRD USE: synonymy/identity between verb lemmata in T and H. FOURTH USE (WordNet+Framenet): WordNet synonym and hyponym relations from T's frame elements to H's frame elements.	FIRST USE: Ablation test performed. Positive impact of the resource on two-way run: +0.83% accuracy. Negative impact on three-way run: -0.33% accuracy (-0.5% for two-way derived). SECOND USE (WordNet+VerbOcean+DLSIUAES_negation_list): positive impact on two-way run: +0.66% accuracy. Negative impact on three-way run: -1% (-0.5% for two-way derived). THIRD USE: No ablation test performed. FOURTH USE (WordNet+Framenet): positive impact on two-way run: +1.16% accuracy. Negative impact on three-way run: -0.17% (the same for two-way derived).
FBKirst	RTE5	3.0	Extraction of a set of 2698 English entailment rules for terms connected by the hyponymy and synonymy relations	No ablation test performed
JU_CSE_TAC	RTE5		WordNet based Unigram match: if any synset for the H unigram matches with any synset of a word in T then the hypothesis unigram is considered as a WordNet based unigram match.	Ablation test performed. Positive impact of the resource: +0.34% on two-way task.
PeMoZa	RTE5		FIRST USE: Derivational Morphology. SECOND USE: Verb Entailment.	Ablation tests performed. FIRST USE. Impact of the resource on two-way task: -0.5%/+1% accuracy respectively on run1 and run2. SECOND USE. Impact of the resource on two-way task: +1.33%/-0.33% accuracy respectively on run1 and run2.
QUANTA	RTE5		Several relations from wordnet, such as synonyms, hyponym, hypernym et al.	Ablation test performed. Negative impact of the resource: -0.17% on two-way task.
Rhodes	RTE5		FIRST USE: Lexicon based match: we chose a very simple metric: matching between words in T and H based on a path of distance at most 2 in the WordNet graph, using any links (hyponymy, hypernymy, meronymy, pertainymy, etc.) SECOND USE: contradiction detection based on antonymy relation	FIRST USE: Ablation test performed. Positive impact of the resource: +3.17% accuracy on two-way, +4% on three-way task. SECOND USE: no ablation test performed.
Sagan	RTE5		Used to obtain two features (string similarity based on Levenshtein distance and semantic similarity) in the training and testing steps of the system.	Ablation test performed. Null/negative (-0.87%) impact of the resource respectively on two-way and three-way task.
Siel_09	RTE5		Similarity between nouns using WN tool	Ablation test performed. Impact of the resource: +0.34% accuracy on two-way, -0.17% on three-way task.
UAIC	RTE5		FIRST USE: Antonymy relation to detect contradiction. In order to broaden the domain of the antonymy relation, we consider a combination of synonyms and antonyms. Used in combination with VerbOcean. SECOND USE: Synonymy, hyponymy and hypernymy for nouns and adjectives. Used in combination with eXtended WordNet relations.	FIRST USE: Ablation test performed (Wordnet + VerbOcean). Positive impact of the two resources together: +2% accuracy on two-way, +1.5% on three-way task. SECOND USE: Ablation test performed (Wordnet + eXtended WordNet). Positive impact of the two resources together: +1% accuracy on two-way, +1.33% on three-way task.
UB.dmirg	RTE5		When using WordNet, we assume that a term is semantically interchangeable with its exact occurrence, its synonyms, and its hypernyms. In extracting hypernyms, we exclude the hypernyms that are more distant than two links to the original terms in WordNet synsets.	Two ablation tests performed. The first for Wordnet alone, the second for both WordNet and Framenet. Null impact of the resource(s) on two-way task for both ablations.
UI_ccg	RTE5		Word similarity == identity	Ablation test performed. Positive impact of the resource: +4% accuracy on two-way task.
Unimelb	RTE5		Synonyms, derivationally-related forms.	Used in the search task.

Participants*	Campaign	Version	Specific usage description	Evaluations / Comments
AUEB	RTE4			Data taken from the RTE4 proceedings. Participants are recommended to add further information.
BIU	RTE4	3.0	Synonyms, hyponyms (2 levels away from the original term), the hyponym_instance relation and derivations. Also used as part of our novel lexical-syntactic resource	0.8% improvement in ablation test on RTE-4. Potential contribution is higher since this resource partially overlaps with the novel lexical-syntactic rule base
Boeing	RTE4	2.0	Semantic relation between words	No formal evaluation. Plays a role in most entailments found
Cambridge	RTE4	3.0	Meaning postulates from WordNet noun hyponymy, e.g. forall x: cat(x) -> animal(x)	No systematic evaluation
CERES	RTE4	3.0	Hypernyms, antonyms, indexWords (N,V,Adj,Adv)	Used, but no evaluation performed
DFKI	RTE4	3.0	Semantic relation between words	No separate evaluation
DLSIUAES	RTE4			Data taken from the RTE4 proceedings. Participants are recommended to add further information.
EMORY	RTE4			Data taken from the RTE4 proceedings. Participants are recommended to add further information.
FbkIrst	RTE4	3.0	Lexical similarity	No precise evaluation of the resource has been carried out. In our second run we used a combined system (EDITSneg + EDITSallbutneg), and we had an improvement of 0.6% in accuracy with respect to the first run in which only EDITSneg was used. EDITSallbutneg exploits lexical similarity (WordNet similarity), but we can’t affirm with precision that the improvement is due only to the use of WordNet
