Figure 1.14 Ranking of features by VIKOR method.

Figure 1.7 shows that the alternative H10 scored rank 1 for the features “Cost,” “Medicare,” and “Infrastructure,” the alternative H6 for the feature “Staff” and the alternative H9 for the feature “Time.” These data can be used for benchmarking by all the hospitals to improve their process.

1.9 Conclusion

Social media text analytics can be used in “brand experience” research. It gives the experience and strategy for building the long term customer-brand relationship. Text analytics research found that applying content analysis to user-generated content provides a rich opportunity to study users’ style of writing, patterns, or preferences. Content analysis research helps all other data analysts to change their research direction to social media text analytics. The reports from different healthcare service providers recommended that the hospital status and the service quality are the two important factors that go hand-in-hand. They also reported that the hospitals have to be keen on their online reputation so as to manage the trust and relationship with their clients or patients. The chapter focused on identifying the features from the users’ reviews, ranked them using multi-criteria decision making techniques, and identified the areas for improvement in specific aspects of healthcare services and its operations. This work can be extended to time-series based sentiment analysis for the features extract which would be much helpful for predicting the profit of a product or Organization and the customer satisfaction. Sarcasm in the review documents and classification of fake reviews would give further improvement in this text analytics.

1.10 Future Work

      This work can be improved with complete automation in building the domain Ontology, and exploring various methods for visualizing the results, which enables the users to get more information. In this study, individuals, siblings, and concepts are the only items considered for Ontology learning. It can be further extended and modeled as “sentiment domain dictionary” with the set of positive and negative words.

      However, the work can be extended to map relationship between concepts, in addition to the existing terms. It can be done by the development of multi-agent system for integration of different domain Ontology using their properties. This in turn helps to develop expert systems solution or decision support system for any decision-making problem.
