Opinion Mining Summarization and Automation Process: A Survey
In this modern age, the internet is a powerful source of information. Roughly, one-third of the world population spends a significant amount of their time and money on surfing the internet. In every field of life, people are gaining vast information from it such as learning, amusement, communication, shopping, etc. For this purpose, users tend to exploit websites and provide their remarks or views on any product, service, event, etc. based on their experience that might be useful for other users. In this manner, a huge amount of feedback in the form of textual data is composed of those webs, and this data can be explored, evaluated and controlled for the decision-making process. Opinion Mining (OM) is a type of Natural Language Processing (NLP) and extraction of the theme or idea from the user's opinions in the form of positive, negative and neutral comments. Therefore, researchers try to present information in the form of a summary that would be useful for different users. Hence, the research community has generated automatic summaries from the 1950s until now, and these automation processes are divided into two categories, which is abstractive and extractive methods. This paper presents an overview of the useful methods in OM and explains the idea about OM regarding summarization and its automation process
Text Summarization Technique for Punjabi Language Using Neural Networks
In the contemporary world, utilization of digital content has risen exponentially. For example, newspaper and web
articles, status updates, advertisements etc. have become an integral part of our daily routine. Thus, there is a need to build
an automated system to summarize such large documents of text in order to save time and effort. Although, there are
summarizers for languages such as English since the work has started in the 1950s and at present has led it up to a matured
stage but there are several languages that still need special attention such as Punjabi language. The Punjabi language is
highly rich in morphological structure as compared to English and other foreign languages. In this work, we provide three
phase extractive summarization methodology using neural networks. It induces compendious summary of Punjabi single text
document. The methodology incorporates pre-processing phase that cleans the text; processing phase that extracts statistical
and linguistic features; and classification phase. The classification based neural network applies an activation function-
sigmoid and weighted error reduction-gradient descent optimization to generate the resultant output summary. The proposed
summarization system is applied over monolingual Punjabi text corpus from Indian languages corpora initiative phase-II.
The precision, recall and F-measure are achieved as 90.0%, 89.28% an 89.65% respectively which is reasonably good in
comparison to the performance of other existing Indian languages" summarizers.This research is partially funded by the Ministry of Economy, Industry and Competitiveness, Spain (CSO2017-86747-R)
