Unsupervised Data Generated for GeoQuery and SAIL Datasets

This repository contains the generated unsupervised data for GeoQuery and SAIL semantic parsing tasks.

For a detailed description of this see below and in the paper Semantic Parsing with Semi-Supervised Sequential Autoencoders, Kočiský et al., EMNLP 2016. Please cite the paper if you use this corpus in your work.

GeoQuery Data

For GeoQuery, we fit a 3-gram Kneser-Ney model to the queries in the training set and sample about 7 million queries from it. We ensure that the sampled queries are different from the training queries, but do not enforce validity.

SAIL Data

For this task we hand designed a maze by trying to approximately replicate the key statistics of the existing mazes (corridor lengths, number and types of intersections, object distribution).

Path navigation action sequences

To approximate the distribution of instruction sequences that correspond to utterances in the SAIL dataset, we selected randomly a starting point, an ending point, and a starting and ending orientation in the hand-designed maze. We then found the shortest action sequence between the two points. The sequence was then segmented into roughly utterance-sized instructions using heuristic rules.
