An Expert System Technique for Sentiment Analysis of Opinions

To help the users and the product owners it is quite necessary to extract aspects from the online reviews, their sentiment polarities, and associations between them. There is a great deal of work done in the field of sentiment analysis. Lexical and learning-based systems can be combined to separate the assessments from online opinions and reviews. In learning-based techniques, the Gaussian mixture model can be used for getting probabilistic results for polarities against aspects and naïve baize classifiers for the problem of spam comments which produced better and competitive results against previous techniques

Analysis and Evaluation of Requirement Engineering Process at NorthBay Solutions

Requirement engineering has become an essential part as it deals with the process of definition,documentation and maintenance of requirements for software product. Requirement Engineeringstandards like IEEE/ISO/IEC has defined a standardized approach for Requirement Engineeringprocess in developing software solutions. In Pakistan a great range of software houses does notfollows any standardized approach to build software solutions. This research is aiming to help thosegraduating students and others who are not clear about the actual implementation of RequirementEngineering process in the industry. Interviews with Project Leads have been carried out to inquireabout the Requirement Engineering standards and process implementation at ‘NorthBay Solutions’Lahore. Results deduced from this will help students and researchers to get familiar withimplemented solutions of requirement engineering process
