The sentence and question vector representations are created by concatenating the final hidden state vectors after running a bidirectional Gated Recurrent Unit RNN (Cho et al., 2014) over the word embedding vectors. The repo consists of following files/folders: (subset of configurations from default.conf which we have overriden on custom config files), Complete overview of JIANT: https://arxiv.org/pdf/2003.02249.pdf, Tuning baseline model jiant to execute task 'MultiRC'. It finds a matching index of the verb and ties it to the object (noun), # If what asks about an adjective of a noun and not an agent, # if the question has > 1 noun involved implying it's looking for an ADJ but it asks with a noun, ##### these next ones are the same but pertain to an agent #####, ################################################################, # niche case: "Watch your step" type questions, # if there's only 1 agent and it asks about what happened to the noun, # if the WHO question has a basic structure.

There was a problem preparing your codespace, please try again. We then used a similarity metric between each sentence vector and the corresponding question vector to score the relevance of each sentence in the paragraph to the question. After manually checking results, it is observed that a particular option with any resemblance to a portion of the paragraph is marked TRUE without taking the question into context. Reading Comprehension is the task of having the reader answer questions based on the given piece of text. No impact on do_target_task_training, load the specified model_state checkpoint for target_training, load the specified model_state checkpoint for evaluation, list of splits for which predictions need to be written to disk, Added colab notebooks with the required data for the above approach in the repository under MultiRC_NER/. While it was able to give partially correct answers, it's single span approach failed in answering multihop questions(as expected). Implemented approach in Repurposing Entailment for Multi-Hop Question Answering Tasks, Added task into the baseline model for the above approach and dataset transformation script under branch "MultiRC_NLI/". Implemented Named-entity-recognition based approach. eg changes: This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.

Mini-Project 3: Sentence Reading Shubham Gupta [email protected] Abstract This Mini Project aims to develop a question answer-ing system that should be able to give an answer based on the knowledge acquired from the given sentence. Since the overwhelming majority of answers to SQuAD questions are contained within one sentence, we have a gold label for which sentence in the passage had the answer to the question. Use Git or checkout with SVN using the web URL. Changed evaluate.py to include softmax(logits) i.e confidence (for labels 0 and 1) in the output json for validation and test. sentence-selection Sentence Selection for Reading Comprehension task on the SQuaD question answering dataset.

The dataset has the unique property of having word spans of the original text passage as answers rather than single word or multiple choice answers. Pre-requisite- Tranformed the MultiRC dataset into an NER dataset with different tags, one each for- paragraph, question, correct and incorrect answer. A tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. # Initialized at the start of the program, # everything below are arrays serve as boostrapped knowledge for the agent, # if the how is asking about an adjective of a noun, # if the how is asking about an adjective of an agent, # this one asks for an adjective verb of an agent, # if how is asking about how much/many someone did an action, # if how is asking about how much/many someone did WITHOUT ADJ, # this does the same but is more niche. b. Facebook RoBERTa Experiment configurations > cp jiant/config/demo.conf jiant/config/multirc.conf: Improve the model over baseline scores on the Multi-RC dataset. A step is a batch update, The word embedding or contextual word representation layer, How to handle the embedding layer of the BERT, The type of the final layer(s) in classification and regression tasks, If true, use attn in sentence-pair classification/regression tasks, Use 'bert_adam' for reproducing BERT experiments, Minimum learning rate. Analysed BERT-QA(fine-tuned on SQuAd) and other fine-tuned BERT models(on STS-B, QNLI) on MultiRC dataset, details in experiments/ folder. Analysed confidence probabilities: Model is very underconfident and most options are labelled as TRUE(1). Are you sure you want to create this branch? The model creates vector representations for each question and context sentence. Researched multi-hop approaches such as Multi-hop Question Answering via Reasoning Chains. This model focuses on part 1 of this reading comprehension task; One important observation- frozen BERT without any pre-training gave approximately the same results. Added python script in "MultiRC_BERT_QA/". Learn more. Basic_Natural_Language_Processing_Program, Cannot retrieve contributors at this time. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. # if the who is a noun receiving an action. Attaches verb to noun, # how someone performs something, find the verb, # if how is asking about how much/many someone did for numbers, # if it asks for a time for when someone went to a noun, # pull up most recent location: matches verb location with the noun, # if the where location doesn't have a verb associated with it and there's no agents, ################### before len(VERB) == 0, # gets matching noun index with matching adjective index, # if a specific date or time is mentioned, # WHAT asks about an item an agent did with. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Reading Comprehension is the task of having the reader answer questions based on the given piece of text. Idea- Using the concept of BIO tagging to train the model on correct tags for the correct answer and vice-versa for the wrong answers. # the parsed sentence goes into this dicitonary, # update sentence and tokens if necessary, # put tokens of sentence into the semantic_structure table, # collect tokens from question and compare them to the semantic_structure to find the answer. Contacted the developers for gaining information on the performance, seems like they don't know how it degraded when they updated the toolkit to incorporate new Allen AI and Huggingface module versions(Issue thread-.

The model has been run in Tensorflow v0.11 . # for ex: Mike kicked hte ball Jake Punched the ball. While most reading comprehension models currently are trained end-to-end, this task can be split into two disctinct parts: The Stanford Question Answering Dataset(https://rajpurkar.github.io/SQuAD-explorer/) is used for experimentation. If nothing happens, download Xcode and try again. 1 INTRODUCTION In The Sentence Reading Problem, The agent's goal is to understand and answer any question based on a given sentence. A tag already exists with the provided branch name. Additional model references- The preprocessed training and dev data files are available in the data folder.
