Applying AHP Technique for Trust Evaluation in the Semantic Web

Abstract

Abstract-The increasing reliance on information gathered from the web and other internet technologies raises the issue of trust. Through the development of semantic Web,One major difficulty is that, by its very nature, the semantic web is a large, uncensored system to which anyone may contribute. This raises the question of how much credence to give each resource. We can't expect eachuser to know the trustworthiness of each resource, nor would we want to assign top-down or global credibility values due to the subjective nature of trust. Trust policiesand trust evaluation mechanisms are needed to filter untrustworthy resource. We tackle this problem by employing a trust model for evaluating trustworthiness ofeach resource. This proposed model uses semantic webmetadata, recommendation, and reputation as based factorfor evaluation algorithm. The weighting and Combination Methods are two main challenges for Proposed Trust evaluation algorithm. These factors have various type and semantic. Therefore we apply the AHP technique for trust evaluation that offers justification for trust decisions andcontrolled trust measurement.Index Terms-AHP, content trust, hybrid trust model, semantic web, trust.

Fuzzy Multicriteria Decision Analysis for Measurement of Document Content Reliability

“…THE FUZZY MULTICRITERIA FRAMEWORK of the aggregation of multiple criteria decision methods is adapted from [7,9,13]. In this section, we first explain the definition of the fuzzy linguistic terms used and then we present the specific multiple criteria method adopted.…”

“…It uses hierarchic structures to represent a decision problem, and then develops priorities for the factors based on DM's judgment [7,13]. Therefore, the decision problem consists of (a) a number of article, denoted as A i (i = 1, 2, ..., n), (b) a set of evaluation criteria C j (j = 1, 2, ... , m) when some of them may refer to the recency of the article, (c) a qualitative assessment x ij (i = 1, 2, ..., n; j = 1, 2, ... , m) representing the performance of each alternative A i with respect to each criterion C j , leading to the determination of a decision matrix for the articles, and (d) a weighting vector representing the relative importance of the evaluation criteria with respect to the overall objective of the problem.…”

Combining Various Trust Factors for E-commerce Platforms Using Analytic Hierarchy Process

“…They also find that the trust level of buyers and the transaction amounts have great impact on sellers' trust [17]. Cami et al apply AHP technique to weigh and combine various factors for trust evaluation, including Semantic Web metadata, recommendation and reputation [18].…”
