This paper presents a first step toward the formalization of the concept of document reliability in the context of Information Retrieval (and Information Filtering). Our proposal is based on the hypothesis that the evaluation of the relevance of a document can also depend on the concept of reliability of a document. This concept has the following properties: (i) it is user-dependent, i.e., a document may be reliable for a user and not reliable for another user; (ii) it is source-dependent, i.e., the source which a document comes from may influence its reliability for a user; and (iii) it is also author-dependent, i.e., the information about who wrote the document may also influence the user when assessing the reliability of a document.

Abstract
This paper presents a first step toward the formalization of the concept of document reliability in the context of Information Retrieval (and Information Filtering). Our proposal is based on the hypothesis that the evaluation of the relevance of a document can also depend on the concept of reliability of a document. This concept has the following properties: (i) it is user-dependent, i.e., a document may be reliable for a user and not reliable for another user; (ii) it is source-dependent, i.e., the source which a document comes from may influence its reliability for a user; and (iii) it is also author-dependent, i.e., the information about who wrote the document may also influence the user when assessing the reliability of a document.
