We present a new weighted session similarity measure to capture the browsing interests of users in web usage profiles discovered from web log data. We base our similarity measure on the reasonable assumption that when users spend longer times on pages or revisit pages in the same session, then very likely, such pages are of greater interest to the user. The proposed similarity measure combines ...

To enhance the credibility level/measure of an intuitionistic fuzzy set (IFS), this study proposes notion (IFCS) to express hybrid information a pair membership degree and nonmembership degree. Next, we propose generalized distance similarity measures between IFCSs then further generalize weighted measure trigonometric function-based IFCSs, including cosine, sine, tangent, cotangent based on IF...

Trust relation, as defined in Social Network Analysis (SNA), is one of the recent notions considered decision making. This inspired our integration trust relation constructing a similarity–trust network. Similarity experts' preferences analyzed inclusively with by defining new combination function both attributes. The agglomerative hierarchical clustering approach applied to group experts into ...

This thesis proposes a weighted DAG (wDAG) similarity algorithm for match-making in e-Business environments. We focus on the metadata representation of buyer and seller agents, as well as a similarity and associated simplicity measure over this information. In order to make the interaction between agents more meaningful and fine-grained, we choose node-labeled, arc-labeled and arc-weighted dire...

The measurement of semantic similarity has been widely recognized as having a fundamental and key role in information science and information systems. Although various models have been proposed to measure semantic similarity, these models are not able effectively to quantify the weights of relevant factors that impact on the judgement of semantic similarity, such as the attributes of concepts, ...

In this paper the role of logic as a formal basis to exploit the query evaluation process of the boolean model and of weighted boolean models is analysed. The proposed approach is based on the expression of the constraint imposed by a query term on a document representation by means of the implication connective (by a fuzzy implication in the case of weighted terms). A logical formula correspon...
