Short-text-analyzer

This ShortTextAnalyzer was created to help analyze the open-ended survey response which usually has less than three sentences. The analysis includes topic modeling, sentiment analysis, and visualization. This topic modeling was done using pre-trained representations of language, namely BERT, combine with the clustering algorithm.

How to use

from shorttextanalyzer.core import *

analyzer = shortTextAnalyzer(comments_series, 4)
output_result = analyzer.analyze_getResult()

Here we specify that we want 4 clusters/topic from this data.

Output: result

• sentimentScore: Polarity score ranges from [-1,1] where 1 means positive statement and -1 means a negative statement.
• Subjective: score ranges from [0,1] where 1 refer to personal opinion, emotion or judgment and 0 means it is factual information.
• clusterByKMeans: assigned cluster number for each comments using KMeans
• clusterByHDBSCAN: assigned cluster number for each comments using HDBSCAN
