We present work aimed at compiling an Amharic corpus from the Web and automatically categorizing the texts. ...
We discuss the issues of compiling and annotating a corpus of Amharic news articles from the Web. This corpus was then used in three sets of text classification experiments. ...
The results of our first two experiments are compatible with those of GebreMeskel (2003) who used the standard vector space model and latent semantic indexing for text categorization. ...

Probabilistic topic modeling is a popular choice as the first step of crosslingual tasks to enable knowledge transfer and extract multilingual features. ...
In this paper, we systematically study the knowledge transfer mechanisms behind different multilingual topic models, and through a broad set of experiments with four models on ten languages, we provide ...
Two main branches for topic models are non-probabilistic approaches such as Latent Semantic Analysis (lsa, Deerwester et al. (1990) ) and Non-Negative Matrix Factorization (nmf, Xu, Liu, and Gong (2003 ...

The study espouses a novel approach to handle this challenge by introducing a hierarchical approach that employs Latent Dirichlet Analysis to generate topic models that help build a high-level Psychosocial ...
This study examines the problem of hate speech identification in codeswitched text from social media using a natural language processing approach. ...
Therefore, the Latent Dirichlet Allocation (LDA)
algorithm was used to generate twenty-three semantically meaningful topics or clusters from the large corpus of short-
text messages from social media. ...
