tethne.model.corpus package¶
Module contents¶
Corpus models describe latent topics (dimensions) that explain the distribution of features (eg words) among documents in a Corpus.
Tethne presently represents two corpus models:
| ldamodel.LDAModel | Represents a Latent Dirichlet Allocation (LDA) topic model. |
| dtmmodel.DTMModel | Represents a Dynamic Topic Model (DTM). |
Most model classes are subclasses of BaseModel. It is assumed that each model describes a set of items (eg Papers or authors), a set of dimensions that describe those items (eg topics), and a set of features that comprise those dimensions (eg words).
