INTRODUCTION Social media platforms facilitate information creation, sharing informations to others and retrieval, creating new links for reaching patients or other online health care consumer s. It gives a better solution and immediate information sharing and patients seem to be way ahead of healthcare professionals when using digital technology to access health information [1]. online Health care Information and communication technologies are used for transform how health seekers and patients think about access and digitally provide health care information [2].There are some advantages using social media technologies for patients, health professionals,online health experts and care givers.

For these reasons, there are many research works are involved in health related topics in online health Care communities. Some of the research studies and methodsare based on questionnaires and statistical content analysis. In previous studies, health care information are shared in social media online health care communities were determined according to the number of people, patients and users who used the list and how frequently they posted comments and messages on online health care community [5]. Previous online health care related topic study basedon text mining of medical text isprimarily focused on clinical decisions and medical literature. In recent years, however, person generated scientific text has been shared on many social media offerings, inclusive of clinical weblogs, healthq&a, and online health groups. Denecke (2009) targeted on clinical weblogs and categorized the topics in clinical weblogs into two methods, informative and affective. Brody (2010) used text classification based on latent Dirichlet allocation (LDA) in topic models to detect the relevant components of online reviews of health care experts. Chen (2011) accomplished a cluster techniqueson clinical posts from three online health groups and found that the clusters might be categorized into a fixed of not unusual classes, basic, support, patient-focused, discovered understanding, remedies or methods, treatments and condition management. Fig 1 Social Media in Online health care In this research work, clustering techniques are involvedvaluable for assuming out different types of topic facts. In online health care communities there is large quantity of posts and comments generated by using customers. This data are unstructured, a few studies analyze the content material of fitness subjects and information from the internet. There s a need of textual content mining strategies. It is valuable and analyzes the statistics and mined the retrieval records from vast amount of records inside the online health care forums [6]. II. LITERATURE STUDY Social media analysis in online healthcare recognized different effects and health analysis use by patients for health related issues and reasons within the online healthcare system.

In online health care users can post health care information on how to deal with a certain health condition, it is essential to create reliable online communication to prevent health problems [9]. The vast amount of online health related messages posted by social media users, so it is very difficult and time intense to employ traditional statistical approaches to find valuable health care information. Moreover, social media consumers are generally unwilling to suggest personal information due to privacy concerns, and user data are usually registered and hence it is not easily accessible. To tackle these complications, text mining techniques are recently applied in online health care social media in some research studies [10]. Some research works are using text mining techniques to this user generated medical contents to explore the health care topics that concern online health care information users in online health care forums. III. ONLINE HEALTH CARE TOPIC ANALYSIS AND BENEFITS In Recent year s patients, health seekers and care givers are mostly involved in social media and online health care communities. Hot topics and health problem topics from online communities are helpful and better understand for health related Knowledge.

Some of the text mining approaches are given here. B. Natural Language Processing (NLP) NLP is one of the text analysis methods in Text Mining techniques. It analysis the text formats which are understand by the machine read text. It tends to focus the text into word phrasing, Word Stemming (Removing suffixes), POS tagging (noun, verb, preposition etc.) in the word sentence, multi phrase removal in text etc. C. Information Extraction Information Extraction is to extract the information from structured, unstructured and Semi structured data in text or documents. Information Extraction tasks are source selection, Named Entity reorganization, Tokenization Normalization, Instance Extraction in the Text. D. Preprocessing Methods in Text Mining Preprocessing methods are one of the most important techniques in text mining. Preprocessing step usually consists of some following tasks such as text tokenization, stemming, filtering lemmatization etc. It was briefly described here as E. Text Tokenization Tokenization: Tokenization is the task of splitting a character categorization into (words/phrases) called tokens, and perhaps at the same time throws away certain characters such as punctuation marks. 2931

Step1 Step2 Data collection from Online Health Care Community forums G. Filtering Filtering method is used to remove some words in the given text or documents. A familiar filtering method is stop word removal in stop word removal method Words are frequently applied in the text without having much content information. Example prepositions, conjunctions etc. IV. SENTIMENT ANALYSIS Text Tokenization Text Preprocessing Stemming Filtering Sentiment analysis also defined as opinion mining and emotional analysis.

Step3 Step4 Apply Text Mining Techniques and Algorithms A massive amount of social media websites contains sentences that are concerned in sentiment-based. Sentiment analysis involves the use of Natural Language Processing (NLP), Data, or machine learning methods to mine, classify, or describe the sentiment content of a text source. A. Sentiment Analysis in Text Mining Step5 Fig 2 Frame work for topic analysis from online health care using Text mining F. Stemming Sentiment Analysis Topic Analysis from online Health care Sentiment analysis also known as opinion mining and subjectivity analysis.
