International Journal of Advanced Research in Computer Engineering & Technology (IJARCET) Volume 3 Issue 7, July 2014 A SURVEY ON PERSONALIZED USER SEARCH GOALS USING MULTI SEARCH ALGORITHM M.SENTHAMARAI SELVI1 A.MARIMUTHU2 Research scholar, Department of computer science, Government Arts college,Coimbatore1 Associate Professor,Department of computer science,Government Arts college,Coimbatore2 Abstract- Every user has their own background conceivable that many users dislike the and a specific goal when searching of inconvenience of adapting to a new engine, may information on the web. A common problem of be unaware how to change the default settings in current web search is user search queries are their Web browser to point to a particular short and ambiguous and insufficient way to engine, or may even be unaware of other Web specify user needs exactly. Current web search search engines that exist and may provide better engine typically provide search result without service. Performance differences between Web considering user interest and context, we search engines may be attributable to ranking introduce an effective approach that captures algorithms and index size, among other factors. the user’s conceptual preferences in order to It is well understood in the Information Retrieval provide personalized query suggestions. In (IR) community that different search systems this work first we are integrating the concept perform well for some queries and poorly for of personalization and multi search to make the others [1,2], which suggests that excessive refined results more effective. Based on loyalty to a single engine may actually hinder personalized data we extracting user’s previous searchers.. The approach relies on a classifier to history and providing a database for user so suggest the top-performing engine for a given that further refinement matches the user goals. search query, based on features derived from the In order to search and clustering experience query and from the properties of search result SOC algorithm. pages, such as titles, snippets, and URLs of the top-ranked documents. Key terms- user search goals, personalized data, We seek to promote supported search multisearch results, feedback sessions. engine switching operations where users are encouraged to temporarily switch to a different I.INTRODUCTION search engine for a query on which it can In Web search engines, queries are provide better results than their default search submitted to represent the information needs of engine. Unsupported switching, whereby users users. However, sometimes queries may not navigate to other engines on their own accord, exactly represent users specific information is a phenomenon that may occur for a number needs as different users will have different of reasons: users may be dissatisfied with ideas while submitting the queries. For search results or the interface. We conjecture example, when the query “the sun” is submitted that by proactively encouraging users to try to search engine, some users want to locate the alternative engines for appropriate queries home page of a United Kingdom newspaper, (hence increasing the fraction of sessions that while some others want to learn the natural contain switching) we can promote more knowledge of the sun. Web search engines such effective user searching for a significant fraction as Google, Yahoo!, and Live Search provide of queries. Empirical results presented in this users with keyword access to Web content. They paper support this claim. And also our system are typically loyal to a single one even when it maintains the user behavior by registering into may not satisfy their needs, despite the fact that it, so we have user logs and user interest in the cost of switching engines is relatively low. the database of the every user who have been While most users appear to be content with their already registered.

Thorsten novel approach to infer user search goals for a Joachims did many works on how to use implicit query by clustering a proposed feedback feedback to improve the retrieval quality [9], [7], sessions [1],[2].To demonstrate the proposed [12]. In [3] work, they considered feedback sessions evaluation criterion can help us to optimize the as user implicit feedback and propose a novel parameter in the clustering method when optimization method to combine both clicked and inferring user search goals. Demonstrate that un clicked URLs in feedback sessions to find out clustering feedback sessions is more efficient what users really require and what they do not care. than clustering search results or Thus, we can One application of user search goals is restructuring tell what the user search goals are in detail. web search results.
