5. Abstract
 Web clustering Engines are emerging trend in the field of information
retrieval. They organize search results by topic, thus offering a
complementary view to the flat ranked list returned by the conventional
search engines.
 The search results returned by traditional search engines on different
subtopics or meanings of a query will be mixed together in the list so that the
user may have to sift through a large number of irrelevant items to locate
those of interest. The Web clustering engines categorize the search results
into different hierarchical groups/clusters and display those cluster labels.

6. Introduction
 Web Clustering Engines organize search results by topic, thus offering a
complementary view to the flat ranked list returned by the conventional
search engines.

7. Search Engine
 A search engine is a software system designed to carry out web searches. They search the
World Wide Web in a systematic way for particular information specified in a textual web search
query. The search results are generally presented in a line of results, often referred to as search
engine results pages.
 A search engine is a software program that helps people find the information
they are looking for online using keywords or phrases.

8. Search engine
• Search engine is a website
• Help user to find information on world wide Web.
• Archie is a first search engine
• 1970 Archie stablish is a world first search engine
• The most used search engine is a Google
• Google is invented is 1997 , google is a one of the most
famous search engine.

9. Why web clustering engine?
 Conventional engines are not much efficient in ambiguous queries
 The search results returned by conventional search engines on query will be
mixed together in the list, irrelevant item occurs.
 In this context of search result come into picture!

10. Main advantages of cluster hierarchy
 It makes for shortcuts to the items that relate to the same meaning
 It allows better topic understanding
 It favors systematic exploration of search results.

11. Issues in implementation of clusters
 Short input description
 Meaningful labels
 Selection of similar measure
 Grouping of objects into clusters
 Computation efficiency

12. Architecture
• Practical implementations of Web search clustering engines will usually consist of four
general components: search results acquisition, input preprocessing, cluster
construction, and visualization of clustered results

13. Search result acquisition
 The task of search result acquisition is to provide input for the rest of system.
 Based on the query, the acquisition component must deliver 50 to 500 results,
each of which should contain
 -Contextual snippet
 Title URL pointing to the full text being referred to
 The source of search results can be any public search engines such as ggoogle
yahoo etc.
 The most elegant way of searching results from search engines is by using
application programming interfaces (APIs) these engines provide.

14. Conclusion
 Web clustering engines organize search results by topic thus offering a
complimentary view to the flat-ranked list returned by conventional search
engines.
 Due to lack of efficient methods of performance evaluation of clustering
engines they are not seeking the attention of the people.
