+## Dataset Summary 
+
+This dataset contains 2,394 labeled Wikipedia claims for 55 topics. The dataset includes the stance (Pro/Con) of each claim towards the topic, 
+as well as fine-grained annotations, based on the semantic model of [Stance Classification of Context-Dependent Claims](https://aclanthology.org/E17-1024/) (topic target,
+topic sentiment towards its target, claim target, claim sentiment towards its target, and the relation between the targets).  
+
+The dataset is divided into a training set (25 topics, 1,039 claims) and a test set (30 topics, 1,355 claims).
+
+## Dataset Structure
+
+* topicId - internal topic ID
+* split - train or test
+* topicText - the topic text
+* topicTarget - sentiment target of topic
+* topicSentiment - topic sentiment towards its target (1:positive/-1:negative)
+* claims.claimId - claim internal ID
+* claims.stance - PRO or CON
+* claims.claimCorrectedText - the corrected version of the claim
+* claims.claimOriginalText - the original version of the claim
+* claims.Compatible - is the claim compatible with the semantic model of [Stance Classification of Context-Dependent Claims](https://aclanthology.org/E17-1024/)? (yes/no)
+        
+The following fine-grained annotations are specified only for "compatible" claims
+* claims.claimTarget.text - claim sentiment target text (in the corrected version of the claim)
+* claims.claimTarget.span.start - 0,
+* claims.claimTarget.span.end - 31
+* claims.claimSentiment - claim's sentiment towards its target (1:positive/-1:negative)
+* claims.targetsRelation - relation between claim target and topic target ((1:consistent/-1:contrastive))

We introduce the complementary task of Claim Stance Classification, along with the first benchmark dataset for this task. We decompose this problem into: (a) open-domain target identification for topic and claim (b) sentiment classification for each target, and (c) open-domain contrast detection between the topic and the claim targets. Manual annotation of the dataset confirms the applicability and validity of our model. We describe an implementation of our model, focusing on a novel algorithm for contrast detection. Our approach achieves promising results, and is shown to outperform several baselines, which represent the common practice of applying a single, monolithic classifier for stance classification.",

+## Notes
+
+(1) Claim annotations and the experiments reported in [Stance Classification of Context-Dependent Claims](https://aclanthology.org/E17-1024/) and [Improving Claim Stance Classification with Lexical Knowledge Expansion and Context Utilization](https://aclanthology.org/W17-5104/)
+    are based on the corrected version of the claim. See [A Benchmark Dataset for Automatic Detection of Claims and Evidence in the Context of Controversial Topics](https://aclanthology.org/W14-2109/) for description of generating 
+    corrected version for claims. The original version is the claim as it is found in the clean version of 
+    the article, with no further editing.
+
+(2) The topics and claims partially overlap with the CE-EMNLP-2015 dataset:
