Abstract: Disclosed herein are techniques and systems for classifying and moderating text using a machine learning approach that is based on a word embedding process. For instance, word embedding vectors may be used to determine clusters of associated text (e.g., similar words) from a corpus of comments maintained by a remote computing system. The remote computing system may then identify, within the corpus of comments, a subset of comments that include text from a given cluster that was determined, from human labeling input, to include a particular type of word or speech. Using this information, the corpus of comments may be labeled with one of multiple class labels. A machine learning model(s) may be trained to classify text as one of the multiple class labels using a sampled set of labeled comments as training data. At runtime, text can be moderated based on its class label.

Abstract: The disclosed system continuously refines a model used by an Automatic Speech Recognition (ASR) system to enable fast and accurate transcriptions of detected speech activity. The ASR system analyzes speech activity to generate text transcriptions and associated metrics (such as minimum Bayes risk and/or perplexity) that correspond to the quality of or confidence in each generated transcription. The system employs a filtering process to select certain text transcriptions based in part on one or more associated quality metrics. In addition, the system corrects for known systemic errors within the ASR system and provides a mechanism for manual review and correction of transcriptions. The system selects a subset of transcriptions based on factors including confidence score, and uses the selected subset of transcriptions to re-train the ASR model. By continuously retraining the ASR model, the system is able to provide ever faster and more accurate text transcriptions of detected speech activity.
