We ar looking for a social network sentiment analysis expert. The expert should have background in natural languge processing, data mining (text mining) and machine learning algorithms. The development platform can be selected among any programming language, but Java is preferred. The project requires to develop a novel hybrid sentiment analysis framework with machine learning algorithms. The implementations of some algorithms may be added from existing implementations from Weka or anyother open source software to the developed platform. The platform should be compatible to different datasets. The platform should allow user to change the configuration of the model easily. For example, changing the classification algorithm of Naive bayes with another classifier should be easily changed. The developed framework should outperform existing sentiment analysis classifiers in terms of accuracy, precision, etc. metrics. The framework will be tested on several (4-5 different) sentiment benchmark data sets, such as twitter, movie recommendation, etc. Sample plan for the project is given below: Other plan suggestions are welcome, but the total project deadline is 9 months max and budget is confined to 3000$. Please keep these considerations in mind. The coder is also expected to submit a "Progress report" at the end of each month. ------------------------------------------------------------------------------------------ Milestones Description Month 1 Analysis & Propose of Algorithm, Identification of Existing Algorithms, Ensemble Techniques, Identification of Datasets to be used. Month 2 Implementation and Results of Algorithm 1 Month 3 Implementation and Results of Algorithm 2 Month 4 Implementation and Results of Algorithm 3 Month 5 Implementation and Results of Ensemble Technique 1 Month 6 Implementation and Results of Ensemble Technique 2 Month 7 Implementation and Results of Ensemble Technique 3 Month 8 Comparison of Results of the Individual Algorithms and Ensemble Techniques ---------------------------------------------------------------------------------------------------

Hello. I was working on a similar project a couple of years ago. I have a Msc degree in AI and my thesis was about data mining and web mining applications. I have worked in text processing applications in several domains such as Twitter, Amazon, ... In one of the projects I tried to extract product reviews from Amazon and develop some sentiment analysis algorithms. To evaluate the algorithms we used RATE of the reviews. For example the text of a 5-star review is POSITIVE and a 2-start review is NEGATIVE, ... Anyway, its for a couple of years ago. I have some java codes to show you as a demo. If you are interested in my bid, please contact me and lets talk about the details. Thanks

Hi, I am in my 3rd year of PhD in NLP (working on SA) and I am well versed with Machine Learning. I have already managed to implement an ensemble of classifiers for SA viz. A rule Based Classifier, and Statistical classifiers using Naive Bayes, SVMs (Multikernel and Multiclass) and Maximum Entropy techniques. I have taken Movie Review and Twitter datasets for training, tuning and testing my algorithms. The feature I have taken are N-gram features (word,stems and lemmas), Sentiment flips, Scores from SentiWordnet and several other linguistic features (Like presence of certain kind of adjectives) etc. The whole framework has been implemented using Python, NLTK and Scikit-learn. The accuracies reported are in the order of 80%-90% (can be improved). The framework is capable enough to take data from domains other than Movie reviews and twitters. I can re-implement the systems in JAVA if you want. I do not need more than 60 days for this work and I am confident about that. Finally, I am new to FL and my profile is not complete because I do not want to waste my time going through FL exams. But,I feel I have the appropriate experience/knowledge for this job. Please revert if you feel so. Best,Abhijit
