Enriched LDA (ELDA): Combination of latent Dirichlet allocation with word co-occurrence analysis for aspect extraction

The competence of the proposed ELDA for the aspect extraction task is evaluated through experiments on two datasets in the English and Persian languages. The experimental results indicate that ELDA not only outperforms the state-of-the-art alternatives in terms of topic coherence and precision, but also has no particular dependency on the written language and can be applied to all languages with reasonable accuracy. Thus, ELDA can impact natural language processing applications, particularly in languages with limited linguistic resources.
