Informatics | An Open Access Journal from MDPI

            SPECIAL ISSUE: "Information Analysis and Retrieval in Social Media"



Dear Colleagues,

We are organizing a Special Issue entitled: "Information Analysis and Retrieval in 
Social Media" in the journal informatics. This is an international peer-reviewed open 
access journal on information and communication technologies, human–computer interaction, 
and social informatics and is published quarterly online by MDPI. For detailed 
information on the journal, please refer to https://www.mdpi.com/journal/informatics.

The multitude of contents that are generated every day through social platforms confront 
users with the problem of accessing information relevant to their information needs. 
Over the years, Information Retrieval has proposed various solutions to help users solve 
this "information overload" problem; however, the characteristics of the content generated 
through social media require a new phase of analysis and the development of new solutions.

First of all, social content is produced at a speed and in volumes not comparable to 
those of traditional content disseminated in the form of Web pages. Secondly, the 
purposes for which users search on social platforms may be different from those of 
traditional Web search. It must also be taken into account that the aspect of social 
relations that connect users in virtual communities and the homophily property that 
distinguishes users can lead to bias in the information received both from custom search 
engines and from recommendation systems. Another aspect concerns the fact that the 
credibility of the content disseminated through social media can hardly be verified, 
and this is an impacting feature when evaluating the relevance of a search result. 
Finally, traditional evaluation of IR systems, following the Cranfield paradigm, must 
take into account the social content characteristics through the test collections 
and metrics used.

The purpose of this Special Issue is therefore to encourage the study and development 
of Information Retrieval solutions that consider the peculiarities of the social platforms 
and the contents generated therein to guarantee users’ access to relevant information.
