  In this paper we describe approaches for discovering acoustic concepts and
relations in text. The first major goal is to be able to identify text phrases
which contain a notion of audibility and can be termed as a sound or an
acoustic concept. We also propose a method to define an acoustic scene through
a set of sound concepts. We use pattern matching and parts of speech tags to
generate sound concepts from large scale text corpora. We use dependency
parsing and LSTM recurrent neural network to predict a set of sound concepts
for a given acoustic scene. These methods are not only helpful in creating an
acoustic knowledge base but in the future can also directly help acoustic event
and scene detection research.
