Paper:
User generated content contains opinionated texts not only in dominant languages (like English) but also less dominant languages( like Amharic). However, negation handling techniques that supports for sentiment detection is not developed in such less dominant language(i.e. Amharic). Negation handling is one of the challenging tasks for sentiment classification. Thus, this work builds negation handling schemes which enhances Amharic Sentiment classification. The proposed Negation Handling framework combines the lexicon based approach and character ngram based machine learning model. The performance of framework is evaluated using the annotated Amharic News Comments. The system is outperforming the best of all models and the baselines by an accuracy of 98.0. The result is compared with the baselines (without negation handling and word level ngram model).

Review:
This paper is quite difficult to read. The figures are pixelated. There is almost no organization to the text of the work.
Descriptions are imprecise and lax: for example, "We apply basic preprocessing on Amharic News Comments. These include normalization of Amharic script symbols, tokenization, stop word removal, punctuation mark removal and so on. Amharic writing system is expressed using only consonants. To handle the features of the language is very challenging. We require conversion of Amharic scripts to consonant-vowel form. Particularly, before performing negation handling and stemming, the algorithm converts each Amharic word to its consonant vowel form." What kind of normalization? What kind of tokenization? Did you use outside tools? If so, cite them or refer to the code. If not, then please explain your method more thoroughly. Don't assume all your readers know what consonant-vowel form is. "and so on" is not appropriate. You should explain what the so on is in a paper submitted to a conference. Don't bother telling us the features of the language are challenging. Just tell us how you did it.
Switching between words like "cue" and "clue"
Even the font of the text changes part way through the paper.
Figure 2 is almost entirely uninformative.
The algorithms are poorly displayed and nearly unreadable.
Experiments are too limited.
