Similar Philippine Supreme Court Case Decisions Retrieval System Using Doc2Vec
Abstract
Ranera, Lorenz Timothy Barco. (2019). Similar Philippine Supreme Court Case Decisions Retrieval System using Doc2Vec.
Drafting a case decision is an intensive task for lower court judges which may be a factor in the case backlog problem of the Philippine judiciary. The search for similar Philippine Supreme Court case decisions is a common task done manually in the trial setting in order to support the decision of the judge. Doc2Vec, a common document embedding technique in NLP, and cosine similarity are implemented in order to determine semantically similar case decisions automatically. The model shows to have an accuracy of 76% and exhibits a moderate positive association with the similarity scores of a legal domain expert.
