|Abstract||In this paper a method for extracting semantic information
from online music discussion forums is proposed. The
semantic relations are inferred from the co-occurrence of
musical concepts in forum posts, using network analysis.
The method starts by defining a dictionary of common music
terms in an art music tradition. Then, it creates a complex
network representation of the online forum by matching
such dictionary against the forum posts. Once the complex
network is built we can study different network measures,
including node relevance, node co-occurrence and
term relations via semantically connecting words. Moreover,
we can detect communities of concepts inside the forum
posts. The rationale is that some music terms are more
related to each other than to other terms. All in all, this
methodology allows us to obtain meaningful and relevant
information from forum discussions.
