(IJCSIS) International Journal of Computer Science and Information Security, Vol. 7, No. 3, March 2010 Probabilistic Semantic Web Mining Using Artificial Neural Analysis 1.1 Data, Information, and Knowledge 1. T. KRISHNA KISHORE, 2. T.SASI VARDHAN, AND 3. N. LAKSHMI NARAYANA Abstract Most of the web user’s requirements are 1.1.1 Data search or navigation time and getting correctly matched result. These constrains can be satisfied Data are any facts, numbers, or text that with some additional modules attached to the can be processed by a computer. Today, existing search engines and web servers. This paper organizations are accumulating vast and growing proposes that powerful architecture for search amounts of data in different formats and different engines with the title of Probabilistic Semantic databases. This includes: Web Mining named from the methods used. Operational or transactional data such as, With the increase of larger and larger sales, cost, inventory, payroll, and accounting collection of various data resources on the World No operational data, such as industry Wide Web (WWW), Web Mining has become one sales, forecast data, and macro economic data of the most important requirements for the web Meta data - data about the data itself, such users. Web servers will store various formats of as logical database design or data dictionary data including text, image, audio, video etc., but definitions servers can not identify the contents of the data. 1.1.2 Information These search techniques can be improved by The patterns, associations, or relationships adding some special techniques including semantic among all this data can provide information.

Concept of Data Mining warehousing is defined as a process of centralized 294 http://sites.google.com/site/ijcsis/ ISSN 1947-5500 (IJCSIS) International Journal of Computer Science and Information Security, Vol. 7, No. 3, March 2010 data management and retrieval. Data warehousing, analytical software are available: statistical, like data mining, is a relatively new term although machine learning, and neural networks. Generally, the concept itself has been around for years. Data any of four types of relationships are sought: warehousing represents an ideal vision of Classes: Stored data is used to locate data in maintaining a central repository of all predetermined groups. For example, a restaurant organizational data. chain could mine customer purchase data to 1.2 What can data mining do? determine when customers visit and what they Data mining is primarily used today by typically order. This information could be used companies with a strong consumer focus - retail, to increase traffic by having daily specials. financial, communication, and marketing Clusters: Data items are grouped according to organizations. It enables these companies to logical relationships or consumer preferences. determine relationships among "internal" factors For example, data can be mined to identify such as price, product positioning, or staff skills, market segments or consumer affinities. and "external" factors such as economic indicators, Associations: Data can be mined to identify competition, and customer demographics. And, it associations. The beer-diaper example is an enables them to determine the impact on sales, example of associative mining. customer satisfaction, and corporate profits. Sequential patterns: Data is mined to anticipate Finally, it enables them to "drill down" into behavior patterns and trends. For example, an summary information to view detail transactional outdoor equipment retailer could predict the data. likelihood of a backpack being purchased based With data mining, a retailer could use on a consumer's purchase of sleeping bags and point-of-sale records of customer purchases to send hiking shoes. targeted promotions based on an individual's Data mining process includes various internal purchase history. By mining demographic data operations as shown in Fig 1 from comment or warranty cards, the retailer could develop products and promotions to appeal to specific customer segments. For example, Blockbuster Entertainment mines its video rental history database to recommend rentals to individual Fig 1: Data Mining Process customers.

Opinion extraction from online sources: Specific decision tree methods include There are many online opinion sources, e.g., Classification and Regression Trees (CART) and customer reviews of products, forums, blogs and Chi Square Automatic Interaction Detection chat rooms. Mining opinions (especially consumer (CHAID). CART and CHAID are decision tree opinions) is of great importance for marketing techniques used for classification of a dataset. intelligence and product benchmarking. We will They provide a set of rules that you can apply to introduce a few tasks and techniques to mine such a new (unclassified) dataset to predict which sources. records will have a given outcome. CART Knowledge synthesis: Concept segments a dataset by creating 2-way splits while hierarchies or ontology are useful in many CHAID segments using chi square tests to create applications. However, generating them manually multi-way splits. CART typically requires less is very time consuming.
