AMR-LE
This is a branch which includes the model weight for AMR-LE. AMR-LE is a model that been fine-tuned on AMR-based logic-driven augmented data. The data is formed as (original sentence, logical equivalence sentence, logical inequivalence sentence). We use Abstract Meaning Representation (AMR) to automatically construct logical equivalence and logical inequivalence sentences. We use constrastive learning to train the model to learn to identify whether two sentences are logically equivalent or logically inequivalent. You are welcome to fine-tune the model weights on the dowstream tasks as logical reasoning reading comprehension tasks (ReClor and LogiQA) and natural language inference tasks (MNLI, MRPC, QNLI, RTE and QQP). We achieved #2 on the ReClor Leaderboard.
Here is the original links for AMR-LE including paper, project and leaderboard.

In this repository, we upload the model weight which has been trained on the dataset that has the ratio of positive sample and negative sample as 1 and 2. We use AMR with four logical equivalence laws (Contraposition law, Commutative law, Implication law, Double negation law) to construct 4 different logical equivalence/inequivalence sentences.

Some test examples that you may copy and paste them into the right side user input area.
The expected answer for the following example is they are logically inequivalent which is 0. Use constraposition law (If A then B <=> If not B then not A) to show that following example is false.
If Alice is happy, then Bob is smart.
If Alice is not happy, then Bob is smart.
The expected answer for the following example is they are logically equivalent which is 1. Use constraposition law (If A then B <=> If not B then not A) to show that following example is true.
If Alice is happy, then Bob is smart.
If Bob is not smart, then Alice is not happy.
The expected answer for the following example is they are logically inequivalent which is 0. Use double negation law (A <=> not not A) to show that following example is false.
Alice is happy.
Alice is not happy.
The expected answer for the following example is they are logically equivalent which is 1. Use double negation law (A <=> not not A) to show that following example is true.
Alice is happy.
Alice is not sad.
The expected answer for the following example is they are logically inequivalent which is 0. Use implication law (If A then B <=> not A or B) to show that following example is false. The or in not A or B refer to the the meaning of otherwise in natural language.
If Alan is kind, then Bob is clever.
Alan is kind or Bob is clever.
The expected answer for the following example is they are logically equivalent which is 1. Use implication law (If A then B <=> not A or B) to show that following example is true. The or in not A or B refer to the the meaning of otherwise in natural language.
If Alan is kind, then Bob is clever.
Alan is not kind or Bob is clever.
The expected answer for the following example is they are logically inequivalent which is 0. Use commutative law (A and B <=> B and A) to show that following example is false.
The bald eagle is clever and the wolf is fierce.
The wolf is not fierce and the bald eagle is not clever.
The expected answer for the following example is they are logically equivalent which is 1. Use commutative law (A and B <=> B and A) to show that following example is true.
The bald eagle is clever and the wolf is fierce.
The wolf is fierce and the bald eagle is clever.
