AN IMPROVEMENT TOWARDS CONSIDERING PREFERENCES OF WEB SEARCH

With the rising number of web users using Smartphone in addition to its individualized service under examination, the environment of Smartphone does not make available user’s search rankings suitable to personal inclinations. Ontology-based user profiles can productively confine users’ content as well as location preferences and make use of the preferences to make relevant results for users. A realistic design was introduced for Personalized Mobile Search Engine by adopting the approach of meta-search which relies on the commercial search engines, to carry out a genuine search. In Personalized Mobile Search Engine, ontologies were accepted to structure the concept space intended for the reason that they not only can stand up for concepts but also hold the relations between concepts. The design of personalized mobile search engine addressed the issues such as restricted computational power on mobile devices, and minimization of data transmission. Proposed design accept server-client model in which user queries are forwarded towards a personalized mobile search engine server for processing training as well as re-ranking rapidly

Enhancing Information Retrieval Relevance Using Touch Dynamics on Search Engine

Using Touch Dynamics on Search Engine is an attempt to establish the possibilities of using user touch behavior which is monitored and several unique features are extracted. The unique features are used for identifying users and their traits according to the touch dynamics. The results can be used for defining automatic user unique searching behavior. Touch dynamics has been discussed in several studies in the context of user authentication and biometric identification for security purposes. This study establishes the possibility of integrating touch dynamics results for identifying user searching preferences and interests. This study investigates a technique of combining personalized search with touch dynamics results information as an approach for determining user preferences, interest measurement and context.

Query Chains: Learning to Rank from Implicit Feedback

This paper presents a novel approach for using clickthrough data to learn ranked retrieval functions for web search results. We observe that users searching the web often perform a sequence, or chain, of queries with a similar information need. Using query chains, we generate new types of preference judgments from search engine logs, thus taking advantage of user intelligence in reformulating queries. To validate our method we perform a controlled user study comparing generated preference judgments to explicit relevance judgments. We also implemented a real-world search engine to test our approach, using a modified ranking SVM to learn an improved ranking function from preference data. Our results demonstrate significant improvements in the ranking given by the search engine. The learned rankings outperform both a static ranking function, as well as one trained without considering query chains.Comment: 10 page

Applying Co-training to Clickthrough Data for Search Engine Adaptation

The information on the World Wide Web is growing without bound. Users may have very diversified preferences in the pages they target through a search engine. It is therefore a challenging task to adapt a search engine to suit the needs of a particular community of users who share similar interests. In this paper, we propose a new algorithm, Ranking SVM in a Co-training Framework (RSCF). Essentially, the RSCF algorithm takes the clickthrough data containing the items in the search result that have been clicked on by a user as an input, and generates adaptive rankers as an output
