ABSTRACT

Online search has become an increasingly important part of every
day lives of common people.We cannot consider web as a knowledge base unless we have
options for searching.Many search engines has evolved as an unavoidable tool for
computer users.But the limitations of these engines has evolved as an unavoidable
tool for computer users.But the limitations of these engines paved the path for research
towards a more advanced and user friendly search method and thus exploratory search
evolved.
Exploratory search is a topic that has grown from the fields of
Information Retrieval and Information seeking ,but has become more and more concerned
with the alternative scenarios of search that have received the majority of focus(returning
the most relevant documents to a Googlelike keyword search).The research is motivated
by questions likewhat if the user does not know which keywords to
use?.Consequently,research has begin to focus on defining the broader set of Information
Behaviors in order to learn about the situations when a user is,or feels,limited by only
having the ability to perform a keyword search.Page 5

The Web
The World Wide Web is a system of interlinked hypertext documents accessed via the
internet .With a web browser,one can view Web pages that may contain
text,images,videos,and other multimedia and navigate between them using hyperlinks.The
World Wide Web was created in 1989 by English scientist Tim BernersLee,working at the
European Organisation for Nuclear Research (CERN)in Geneva,Switzerland,and
releasedin 1992.
WEB 1.0
The information published on the web in a static manner(HTML).It is like your word
document on the web with pictures and formatting done neatly.Hyperlinking the web
pages and bookmarking were two of the most important aspect of Web 1.0 world.
WEB 2.0

Web 2.0 encapsulates the idea of the proliferation of interconnectivity and
interactivity of webdelivered content. Web 2.0 technology encourages light weight
business models enabled by syndication of content and of service and by erase of picking
up by early adopters.Web 2.0 websites allow usersto do more than just retrieve
information.They can build on the interactive facilities of Web 1.0to provide Network
as platform computing ,allowing users to run softwareapplications entirely througha
browser.Page 8



WEB 3.0


Web 3.0 is one of the terms used to describe the evolutionarystage of the Web that follows Web
2.0.Given that technical and social possibilities identified in this latter term are yet to, be fully
realised the nature of defining Web3.0 is highly speculative.The key assumption of web3.0 is that
every data published in web has data that describes the data ie meta data.
Web 3.0 is proposed to have many automated engines which analyze the meaning of every piece
of information in the web and generate automated documents on the basis of th information
Page 9


SEARCH AND INFORMATION RETRIEVAL

In
formation retieval (IR) is the science of searching for information with documents
and for meta data about documents,as well as that of searching relational databases and the World
Wide Web.There is overlap in the usage of the terms data retrieval,document retrieval,information
retreival,and text retrieval,but each also has its own body of literature ,theory,praxis and
technologies.IR is interdisciplinary, based on computer science,information architecture,cognitive
psychology,linguistics,statics and physics.
Automated information retievalsystems are used to recduce what has been called
information overload.Many universities and public librariesuse IR systems to provide access to
books,journals and other documents.Web search engines are the most visible IR applications.
An information retrieval process begins when a user enters a query in to the system.Queries
are formal statements of information needs,for example search strings in web search engines.In
information Retrieval a query does not uniquely identify a single object in the collection.Instead
,several objects may match the query ,perhaps with different degrees of relevancy.

LOOH UP

In lookup various machine generated queries are submitted to the data base and
the result is obtained.Various databases operations are performed to retrieve the correct data.

RETURN RESULT


The result from the data base are displayed to the user according to the page
rank along with a short description.
This is the most common and simplest form of existing searching system.Common
search engines like google and yahoo has started using high end technologie sand algorithms and
even introduces artificial intelligence in ranking ,indexing and key word processing.

EXPLORATORY SEARCH

Exploratory Search covers a broader class of activities (compared to typical information
retrieval),such as investigating,evaluating ,comparing and synthesizing,where new information is
sought in a defined conceptual area;exploratory data analysis is another example of an
information exploration activity.Typically,therefore,such users generally combine querying and
browsing strategies to foster learning and investigation.Page 12

It is clear that better tools to support exploratory searching are needed. The Net generation
will expect to be able to use web resources to conduct lookup, learning and investigative
tasks with fluid user interfaces. Exploratory search makes us all pioneers and adventures
in a new world of information riches awaiting discovery along with new pit falls and costs. Page 29
