  • 1. SENTIMENT MINING THE DESIGN AND IMPLEMENTATION OF AN INTERNET PUBLIC OPINION MONITORING AND ANALYSING SYSTEM
  • 2. The Curious case of Telemachus THE GREEK GOD WHO LOVES TO TRAVEL HAS BEEN REINCARNATED IN INDIA.
  • 3. Abstract A complete framework of an Internet Public Opinion Monitoring and Analyzing System (IOPMAS) provided in paper System composed of (4): ◦ Web crawler ◦ Information processing. ◦ Public opinion information analyzing and mining module. ◦ Information services module. System can collect web pages from the entire web space including news groups, portal websites, forums, BBS, blogs, microblogging websites etc. System gives public opinion information analysis results thorough processing and analyzing collected information This system can help supervisors to timely monitor the concerned public opinion and ‘’guide them’’.
  • 4. Introduction- Public Opinion Public opinion ◦ society and political attitude toward the social administration in certain social space. 250 Mn users are online in India alone, half of them are teens or younger. Exponentially increasing use of social media to voice opinions 5 characteristics of internet public opinion: ◦ 1. Diversity of Information Sources ◦ 2. Massive amount of information opinion ◦ 3. Burstiness of internet public opinion ◦ 4. Public opinion in response to emergencies ◦ 5. Set of massive structured, semi structured and unstructured information
  • 5. EVOLUTION & HISTORY OF SENTIMENT MINING Biber, 1998- Classifying document according to source or source style, with statistically detected stylistic variation as important cue. Karlgren and cutting, 1994- Determining the genre of texts, like subjective or ‘editorial’ texts. Wiebe, et al., 2001- Explicitly finding features that less subjective knowledge is being used. Turnkey and Littman, 2002- Classifying the semantic orientation of words or phrases using linguistic heuristics. ◦ Applied specific unsupervised learning technique based on mutual information between document phrases and the words ‘’excellent’’ and ‘’poor’’ ◦ This mutual information computed by using statistics gathered by search engines (crawlers).
  • 6. BACKGROUND OF IPOMAS Past method based on: ◦ Traditional and manual search engine. ◦ Demand unmanaged, such as full coverage, unstructured information and rapid detection. ◦ Hard to process the unstructured information. Internet public opinion monitoring and analysing system: ◦ Full collection and timely detection. ◦ Effective processing of semi structured and structured information. ◦ Displayed effectively. In this paper, an internet public opinion monitoring and analyzing system are proposed and the corresponding system is designed and implemented.
  • 7. PROPOSED SOLUTION The Framework of the Monitoring and Analyzing System Four modules: ◦ Internet public opinion information collection ◦ Pre-processing of information ◦ Information processing and mining ◦ Public opinion information service
  • 8. Internet public opinion information collection: Data files: Web database file, Series of segment file and Index file. Crawler: an Internet bot that systematically browses the World Wide Web, typically for the purpose of Web indexing. Web parsing- Extracting information from websites by simulating human exploration of world wide web. Reduplicate Web Elimination Web purification- Noise reduction Speech text attributes analysis Tokenization- Segmenting sentences into meaningful phrases Part-of-speech tagging- Speech to text conversion and indexing the information thereon.
  • 9. Information processing and mining- Most Critical Key and useful information from huge amount of data TDT-Topic Detection and Tracking Named entity identification Text classification algorithm Text clustering algorithm Association analysis Emotional tendency analysis
  • 10. Output Tendency Hotspot List Reporting Prediction Monitoring Special Topic Tracking
  • 11. Architecture of IOPMAS DPSB (Data Processing Service Bus) Raw Data (HDFS) Data Processing Node(DPN) Large Scale Full Text Window (IBM Omni Find) Large Scale Relational Database (Oracle) Data Processing Node(DPN) Data Processing Node(DPN) . . . . . . Data Accessing Bus (DAB)
  • 12. RESULTS AND DISCUSSIONS: IPOMS based on SOA (service-oriented-architecture) and ESB (enterprise- service-bus) Leading technology, functional and practical, good scalability. The SOA realize a loose coupling between components by defining good interfaces, ensures good scalability, reusability and maintainability. A functional framework and the overall software architecture of the internet public opinion monitoring and analyzing system. Main technology in the system.
  • 13. Conclusion IOPMS Public Emergencies Security Alert and Better Control of Situation Real-time Feedback on Administration & Policies Scalable Reusable Maintainabl e
  • 14. Scope and Recent Developments Opinion study based on polarity of the words used Opinion Mining for Market Development and New Product Development Sentiment Analysis using fuzzy logic
