Opinion Mining through NLP and Graph Database Maralmaa Erdenebat, May @ Hnin Oo Wai University of Rochester For instance, the following sentences could be Introduction Opinion Mining Conclusion added into adjacency graph through the following Cypher code: “ May loves Database Big data explosion took place in the early Opinion mining is first mentioned in a paper Using Cypher in Neo4j, we were able to 2000 with the world annual unique data System. Maralmaa loves Database System. Prof. written by Dave et al.

We found out the mentioned in the study conducted by Peter for a given item, generating a list of product word “Database” has the highest frequency Lyman and Hal R. Varian from UC Berkeley attributes (quality, features, etc.) and while “May” appears only one time. Through [1]. Following the rise of big data, opinion aggregating opinions about each of them (poor, the simple implementation, the word counts of mining has become a buzz word in processing mixed, good).” Up until now, the definition is still specific words were shown. For further steps in these big data for better analysis and accurate. Sentiment analysis studies the same opinion mining, we could analyze whether the learning. Commercial enterprises have field of study as opinion mining and are used to word is positive, neutral or negative, for started to realize the power of opinion mining broadly mean the computational treatment of Figure 2: Cypher Code instance by filtering through the word cloud in analyzing public sentiment about their opinion, sentiment, and subjectivity in text [5]. brands. Opinion mining relies on tool such as provided in Google API. Through the better Natural Language Processing (NLP) and utilization of machine learning and larger Graph Database Graph Databases to analyze and query text learning datasets, a better and more accurate Graph Database is an online data corpus. We explore the definitions and how opinion can be mined. With graph databases, exactly NLP and Graph Databases are used as management system that uses CRUD (create, better relations can be made on multiple levels tools. read, update and delete) method on graph and provide deeper complexity closer to the data model. The graph data model is human language. composed of nodes and pointers in which Natural Language Processing nodes store the data and pointers represent References Figure 3: Resulting graph model relationships. It is designed so that Though several definitions of NLP exist, the With a bit of modification, multiple lines of text relationships are expressed more dominantly overarching concept refers to the idea of [1] Lyman , Peter, and Hal R.

The graph is made more databases [7]. The fast and efficient method of several tasks. These tasks could include: [3] Allen , James F. “Natural Language sophisticated by including the frequency Processing.” ACM Digital Library, John Wiley and accessing relationships between data is paraphrasing a text (input can be text, oral Sons Ltd., 2003 counter for each relationship and node. Thus, significant for opinion mining which uses the language or from a keyboard), translating [4] Chowdhury, Gobinda G. “Natural Language after setting up the graph database, we can relationship between words in the text corpus the text to another language, providing Processing.” Annual Review of Information query the frequency of the word “Database” to determine public sentiments of a topic.
