Query: Open Intent Discovery through Unsupervised Semantic Clustering and
  Dependency Parsing   Intent understanding plays an important role in dialog systems, and is
typically formulated as a supervised learning problem. However, it is
challenging and time-consuming to design the intents for a new domain from
scratch, which usually requires a lot of manual effort of domain experts. This
paper presents an unsupervised two-stage approach to discover intents and
generate meaningful intent labels automatically from a collection of unlabeled
utterances in a domain. In the first stage, we aim to generate a set of
semantically coherent clusters where the utterances within each cluster convey
the same intent. We obtain the utterance representation from various
pre-trained sentence embeddings and present a metric of balanced score to
determine the optimal number of clusters in K-means clustering for balanced
datasets. In the second stage, the objective is to generate an intent label
automatically for each cluster. We extract the ACTION-OBJECT pair from each
utterance using a dependency parser and take the most frequent pair within each
cluster, e.g., book-restaurant, as the generated intent label. We empirically
show that the proposed unsupervised approach can generate meaningful intent
labels automatically and achieve high precision and recall in utterance
clustering and intent discovery.
