Abstract: In searching process more information gathered
from the web. In this user satisfaction is more crucial based
on search results. So we proposed a new method for getting
optimized results based on user queries. In this method we
will find similar queries and query logs in the input queries.
This method find related queries and also index on them
sequentially and similarity. It can retrieved optimum results
when user search for a query.
I.INTRODUCTION
Let us consider seeing the whole things from the
perspective of a search engine and our only view of user
behavior would be the stream of queries users produce. The
search engine designers adopt this perspective and them
studying these query streams and trying to get optimize the
engines based on such factors as the length of a typical
query. This same perspective has prevented us from
looking beyond the query and at why the users are
performing their searches in the first place. Generally
‘why’ word of user search behavior is actually essential to
satisfying the user’s information need. For everything users
don’t wait at their computer and searching is merely a
means to an end a way to satisfy an underlying goal that
the user is trying to achieve.
True is we have argued elsewhere that
goalsensitivity will be one of the crucial factors in future
search user interfaces. The potential to capitalize on this
goal sensitivity goes beyond the user interface. The ranking
algorithms that implementedwhich results are shown to
users may differ depending on the user search. Consider an
example queries that shows a need for advice may rely
more on usage or connectivity based relevance factors and
while those involving open ended research may weight
traditional information retrieval measures more highly.
Our aim is that web searches lead a diverse set of
underlying user goal and that information of those goals
offers the feature of future improvements to web search
engines. Achieving these improvements is an ambitious

project involving three primary tasks. Initially we have to
create a conceptual group for user goals.
Nextdesignof search engines to combine with user
goals with queries.After that there a way tomodify the
engineto result the goal information. Prior to the worldwide
web the search engine designers could safely consider that
users had an informational goal in mind. That means users
reason for searching was basically to find about their
search keyword. This happened due both to the nature of
the people with access to full text search engines and to the
behavior of the databases that could be searched.
In case of web environment search engines are
used for more than just research. Moreover the most
cursory look at the query logs of any major search engine
makes it clear that the goals underlying web searches are
many and compared. The large body of work described
above has helped us to understand what users are searching
for and how their information retrieving process works and
there have been few chances to look at why users are
searching.
A web search query is a query that a user enters into
a web search engine to satisfy his or her information needs.
Web search queries are distinctive in that they are often
plain text or hypertext with optional search-directives (such
as "and"/"or" with "-" to exclude). They vary greatly from
standard query languages, which are governed by strict
syntax rules as command languages with keyword or
positional parameters.
It computes aspects for a query q using a search
engine query log and augmented with information from a
knowledge base created by more amounts of data. Given a
query q which is related queries are extracted from the
query log. While the logs best input of users interests and
they can also result in redundant aspects. For example top
related queries for vietnam travel visa.
More query logs are of rare utility for generating
aspects for less popular queries and for example there are

much fewer related queries for travel than vietnam travel.
We explained the following algorithmic methods that
address these challenges. Initially we show how redundant
candidate aspects can be removed using search results.
Next we apply classbased label propagation in a bipartite
graph to compute morequality aspects even for a long tail
of less popular queries. Then we show that knowledge
bases can be used to group candidate aspects into
categories that represent a single information need.
Every time of session corresponds to one query
and the documents the user clicked on the url. A query may
be in natural language question or one or more keywords or
phrases. Once a user query is input and a list of documents
is resultedtogether with the document titles. The document
titles are carefully chosen and they give the user a good
idea of the contents of the documents. Thereforeif a user
clicks on a document and it is similar to that the document
is apt to the query or at least related to it to some extent.
II.RELATED WORK
Therefore for our usage we consider a clicked
document to be suitable to the query. This consideration
does not only apply, but to most search engines. If among a
set of documents provided by the system and the user
chooses to click on some of them and it is the user
considers that these documents are more relevant than the
others and based on the information provided in the group
documents. If they are not all suitable then we can still
affirm that they are generally more suitable than the other
documents list. We can extract interesting relationships
from them.
The user search goals from the pseudo documents
by using clustering. The self-constructing is used for the
clustering of similar pseudo documents. The similarities of
the keywords are combined together and form the user
search goals. The clustering is a grouping of algorithms for
cluster analysis in which the allocation of points to clusters
in the same sense as logic. The clustering is the process of
segregating data elements into groups or clusters Therefore
items in the same class are as similar as possible and items
in different classes are as dissimilar as possible. The FCM
algorithm generates partition a finite collection of n
elements into a collection and clusters with respect to some
given criterion. Like k- means algorithm the FCM aims to
minimize an objective function.
For clustering of pseudo documents the similarity
of the documents is clustered using the clustering. The
users in the session have different goals at different times.
It is different to capture such collideinterests of the users in
clusters. This is used to different search goals. The
similarity of the cluster is according on the centroid values.
The search goals having least precision in one cluster have
to appear in another cluster. Therefore discover different
search goals for the users and the fuzzy clustering is used.
The clusters are very knowledgeable and they are stored as
the user search goals.
User Click through data log contains data about
interactions between users and Web search engines. It is
efficient surveys of user experience. It helps to understand
human interaction with Information Retrieval results. The
user click through logs includes all the user actions. It
contains the session id and query term or position of the
URL and click sequence and the URL.
The available data is a large set of user logs from
which we extracted query sessions. A newsession is
defined as follows:
The size of the query logs is very large and there
are about one million queries per week and about half of
query sessions have document clicks. Among all of these
sessions about 90% of them have 1-2 document clicks. If
some of the document clicks are erroneous and we can
expect that most users do click on suitable documents.
III.PROPOSED WORK
In our proposed work we implemented an
algorithm related to queries submitted by the user.Queries
with the clicked URLs are segregated from Query log are
clustered .This is a preprocessing stage before applying
query recommendation algorithm whichqueries are same
and also to determine which is the most same cluster to the
input query.
The token features used in this method are ngrams and they can be easily replaced by other features. An
n-gram defines to a consecutive n word tokens that appear
together and we can consider sentence start ‘<s>’ and
sentence end ‘</s>’ as two special word tokens. Here is the
example that the query ‘trucking jobs’ will activate a
number of features including a) unigrams: ‘trucking’ and
‘jobs’ b) bigrams: ‘<s>+trucking’, ‘trucking + jobs’ and
‘jobs+</s>’; up-to the higher order n-grams can be derived
same.

An n-gram naturally, with its lower-order
counterparts to the linear interpolation Pj (j-j) (x, y). Such
token features with their sparseness are a based on
unbiased representation of queries. This is an added
advantage of utilizing such features is that classification
can be completed prior to information retrieval. But the
truth is using query token features can yield remarkable
grouping performance given training data
We compute clusters by k-meanalgorithm because
of its simple and more efficient for document clustering
compared with other algorithms for documentclustering.
In group process goals is grouped all related queries into
groups according to all data in the query file. The user
submit query the algorithm find out that good group relate
queries and ranks according to its suitable to the user input
query and lastly it recommends all previous suitable
queries to the user. This algorithm is following
The input queries and URLs clicked extracted
from the search engine query file clustered by
clustering algorithm.
b) User submit the query the algorithm finds the
same group to the input query and close to the
centroid of which cluster.
where n is the total number of distinct queries and m is
total number of distinct urls. The initial part of the above
equation is ratio between Wij and total number of wij for
queries with the URL. The next part is ratio between the
total number of distinct URls and the number of URLs
connect(q,l)={1 ; w=0 || 0 ; w>=0}
To find the similarity between queries we used co-efficient
similarity as shown below:
T(q i,qj)=qiq j/|qi2|+|qj2|-q i.qj
To find frequency of query we will find support of every
query in cluster.
Sup(query)=|L|/sum of queries
Lastly the queries are selected in the cluster are rank base
on their similarity and their frequency. The rank score is
measured as shown below
a)
Query1
1
URL 1
Query2
URL 2
Rank(query)=a*T(queryi,q)+b*Sup(q i)
IV. CONCLUSION
In our proposed work we presented the query input based
clustering process over web queries segregated from web.
We applied it on large log files and considered more
amounts of queries to improve analysis of our approach. In
this we extended the queries using keywords similar to the
cluster. In this we considered the user clicks on the answers
to the user queries.
