Special Issue Information

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.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Informatics is an international peer-reviewed open access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Opinion mining techniques, investigating if text is expressing a positive or negative opinion, continuously gain in popularity, attracting the attention of many scientists from different disciplines. Specific use cases, however, where the expressed opinion is indisputably positive or negative, render such solutions obsolete and emphasize the need for a more in-depth analysis of the available text. Emotion analysis is a solution to this problem, but the multi-dimensional elements of the expressed emotions in text along with the complexity of the features that allow their identification pose a significant challenge. Machine learning solutions fail to achieve a high accuracy, mainly due to the limited availability of annotated training datasets, and the bias introduced to the annotations by the personal interpretations of emotions from individuals. A hybrid rule-based algorithm that allows the acquisition of a dataset that is annotated with regard to the Plutchik’s eight basic emotions is proposed in this paper. Emoji, keywords and semantic relationships are used in order to identify in an objective and unbiased way the emotion expressed in a short phrase or text. The acquired datasets are used to train machine learning classification models. The accuracy of the models and the parameters that affect it are presented in length through an experimental analysis. The most accurate model is selected and offered through an API to tackle the emotion detection in social media posts. Full article
