faculty performance.
report generation is a challenging task. Indeed, most organizations deal
with quantitative feedback effectively, whereas qualitative feedback is
either processed manually or ignored altogether.
based on two-layered LSTM model. The first layer predicts the aspects
described within the feedback and later specifies the orientation
(positive, negative, and neutral) of those predicted aspects.
The system performs ABSA(Aspect Based Sentiment Analysis) on student’s
textual feedback to evaluate the teaching quality of a concerned faculty
member.
Our proposed framework is comprised of two layered LSTM model for aspect
extraction and sentiment classification.
The first layer classifies a review sentence in one of the six aspects including
TeachingPedagogy,Behavior,Knowledge,Assessment,Experience,and
General.Next,the second LSTM layer predicts the sentiment orientation (+ve,
−ve or Neutral) expressed towards that particular aspect.
Aspect Extraction
It can be defined as the task of identifying an entity’s relevant features from
the opinionated text.Every entity has some sort of features or aspects
associated, for which the opinions are being formed. Most research studies
were purely attempted to extract only aspects from the available text without
classifying text orientation. They performed this task of aspect extraction
through various supervised, semi-supervised, and deep learning approaches.
Their study was based on the assumption that aspects are basically Nouns
and Noun Phrases. Extraction of such noun phrases is being done through the
association rule mining technique.
Naive Bayes algorithm that is based on conditional probabilities. Ranking
uses Bayes theory concepts.
A Bayes theorem is a mathematical formula that calculates probability by
including the frequency of values and combinations of values in the data
center.
We would like to give ranking for popular items based on a decision tree. If a
learning algorithm produces accurate class probability estimates, it certainly
produces an accurate ranking. But the opposite is not true
