A Smart Web Crawler For A Concept Based Semantic Search Engine, Vinay Kancherla

Master's Projects

The internet is a vast collection of billions of web pages containing terabytes of information arranged in thousands of servers using HTML. The size of this collection itself is a formidable obstacle in retrieving information necessary and relevant. This made search engines an important part of our lives. Search engines strive to retrieve information as relevant as possible to the user. One of the building blocks of search engines is the Web Crawler. A web crawler is a bot that goes around the internet collecting and storing it in a database for further analysis and arrangement of the data.

Recipe Suggestion Tool, Sakuntala Padmapriya Gangaraju

Master's Projects

ABSTRACT
There is currently a great need for a tool to search cooking recipes based on ingredients. Current search engines do not provide this feature. Most of the recipe search results in current websites are not efficiently clustered based on relevance or categories resulting in a user getting lost in the huge search results presented.
Clustering in information retrieval is used for higher efficiency and better presentation of information to the user. Clustering puts similar documents in the same cluster. If a document is relevant to a query, then the documents in the same cluster are also relevant.
The goal …

Association Rule Mining -- Geometry And Parallel Computing Approach, Dongyi Jia

Master's Projects

Mining association rules is a very important aspect in data mining fields. The process to mine association rules not only take much time, but also take huge computing source. How to fast and efficiently find the large itemsets is a crucial point in the association rule algorithms. This paper will focus on two algorithms research and implementation in parallel computing environments. One is Bitmap Combination algorithm, the other is Bitmap FP-Growth algorithm. Compared to Apriori algorithm, both Bitmap Combination and Bitmap FP-Growth algorithms don’t need generate candidate items, avoids costly database scans. Both algorithms need to translate the original database …

Smart Search: A Firefox Add-On To Compute A Web Traffic Ranking, Vijaya Pamidi

Master's Projects

Search engines results are typically ordered according to some notion of importance of a web page as well as relevance of the content of a web page to a query. Web page importance is usually calculated based on some graph theoretic properties of the web. Another common technique to measure page importance is to make use of the traffic that goes to a particular web page as measured by a browser toolbar. Currently, there are some traffic ranking tools available like www.alexa.com, www.ranking.com, www.compete.com that give such analytic as to the number of users who visit a web site. Alexa …

Medical Analysis Question And Answering Application For Internet Enabled Mobile Devices, Loc Nguyen

Master's Projects

Mobile devices such as smart phones, the iPhone, and the iPad have become more popular in recent years. With access to the Internet through cellular or WIFI networks, these mobile devices can make use of the great source of information available on the Internet. Unlike a desktop or laptop computer, an Internet enabled mobile device is designed to be carried around and available to the owner almost instantly at any moment of the day. Despite having such great advantage and potential, searching for information with a mobile device remains a difficult task. Mobile device users have to juggle between different …

Japanese Kanji Suggestion Tool, Sujata Dongre

Master's Projects

Many times, we can see that if we enter a misspelled search term in any of the search engines like Google, it will provide some help with "Did you mean:...." In my project, I am providing some suggestions for the wrong Japanese text entered by a user.

The Japanese language has three types of writing styles - hiragana, katakana and the most difficult, kanji. A single kanji symbol may be used to write one or more different compound words. From the point of view of the reader, kanji symbols are said to have one or more different "readings." Hence, sometimes …

An Online Versions Of Hyperlinked-Induced Topics Search (Hits) Algorithm, Amith Kollam Chandranna

Master's Projects

Generally, search engines perform the ranking of web pages in an offline mode, which is after the web pages have been retrieved and stored in the database. The existing HITS algorithm (Kleinberg, 1996) operates in an offline mode to perform page rank calculation. In this project, we have implemented an online mode of page ranking for this algorithm. This will improve the overall performance of the Search Engine. This report describes the approach used to implement and test this algorithm. Comparison results performed against other existing search engines are also presented in this report. This is helpful in describing the …
