Descriptions
SemEval-2014 Task 4: Aspect Based Sentiment Analysis
SemEval-2015 Task 12: Aspect Based Sentiment Analysis
SemEval-2016 Task 5: Aspect Based Sentiment Analysis
I specialize in restaurants and laptops domain. You can see final results of these contests in [1][2]. The purposes of this project are:
- Aspect based sentiment analysis.
- A sample of bidirectional LSTM (tensorflow 1.2.0).
- A sample of picking some special units of a recurrent network (not all units) to train and predict their labels.
- Compare between struct programming and object-oriented programming in Deep Learning model.
- Build stop words, incremental, decremental, positive & negative dictionary for sentiment problem.
Step by step:
- Used contest data and "addition restaurants review data" to learn word embedding by fastText.
- Used bidirectional LSTM in the model as above. The input of the model is the vector of word embedding that we trained before.
Results
BINGO!!
-
Outperforms state-of-the-art in semeval2014 dataset [3].
-
Achieved 81.2% accuracy. Better than 2.5% winner team in the semeval2015 competition [1].
-
Achieved 85.8% accuracy. rank 3/28 in the semeval2016 competition [2].
