As part of research on modeling user needs and behavior, we describe an approach to select web Information Retrieval Services (IRS) adapted to user’s needs. An experimental system integrating a model of the user by a user profile representing these interests, modeling the behavior by a mechanism for retrieving user interactions and a database of general and vertical SRI is presented. Our resear...

Different approaches based on content or tag information have been proposed to address the problem of tag recommendation for a web page. In this paper, we analyze two approaches in a graph of web pages. Each node is a web page and edges represent hyperlinks. The first approach uses the content while the second one uses tag information in the graph. The second approach makes two assumptions abou...

We describe a hybrid approach to improving search performance by providing a natural language front end to a traditional keyword-based search engine. The key component of the system is iterative query formulation and retrieval, in which one or more queries are automatically formulated from the user’s question, issued to the search engine, and the results accumulated to form the hit list. New qu...

Distributed search systems are an emerging phenomenon in Web search, in which independent topic-specific search engines provide search services, and metasearchers distribute user’s queries to only the most suitable search engines. Previous research has investigated methods for engine selection and merging of search results (i.e. performance improvements from the user’s perspective). We focus in...

with the increased confidence in the use of the internet and the world wide web, the number of electronic commerce (e-commerce) transactions is growing rapidly. therefore, finding useful patterns and rules of users’ behaviors has become the critical issue for e-commerce and can be used to tailor e-commerce services in order to successfully meet the customers’ needs. this paper proposes an appro...

recognizing the importance of the advertising in brand reinforcement and brand credibility, the authors conduct the present research for understanding the customers’ emotional responses toward the brand reinforcement and credibility and its effect on the perceived values and behavioral intentions. hypotheses were tested on data collected from 467 customers of mellat bank in semnan province in i...

due to the quick growth of the world wide web, retrieval of useful informationfrom the internet for a particular web user or a group of users becomes verydifficult. recommendation systems using web usage mining help providing anadaptive web environment for the web users. this paper presents a novel approachfor page recommendation using fuzzy association rule mining algorithm. thismethod extract...

limit to the tension reinforcement ratio ( ρ) in flexural high strength reinforced concrete (hsrc) members is based on the requirement that tension failure as sufficient rotation capacity are ensured at ultimate limit state. however, the provisions for the total amount of longitudinal reinforcement ratio ( ρ and ρ’) are not associated with any rational derivation. in this paper, a quantitative ...
