Blog Rating as an Iterative Collaborative Process
نویسندگان
چکیده
The blogosphere is a part of the World Wide Web, enhanced with several characteristics that differentiate blogs from traditional websites. The number of different authors, the multitude of user-provided tags, the inherent connectivity between blogs and bloggers, the high update rate, and the time information attached to each post are some of the features that can be exploited in various information retrieval tasks in the blogosphere. Traditional search engines perform poorly on blogs since they do not cover these aspects. In an attempt to exploit these features and assist any specialized blog search engine to provide a better ranking of blogs, we propose a rating mechanism, which capitalizes on the hyperlinks between blogs. The model assumes that the intention of a blog owner who creates a link to another blog is to provide a recommendation to the blog readers, and quantifies this intention in a score transferred to the blog being pointed. A set of implicit and explicit links between any two blogs, along with the links’ type and freshness, affect the exchanged score. The process is iterative and the overall ranking score for a blog is subject to its previous score and the weighted aggregation of all scores assigned by all other blogs.

An iterative semi-explicit rating method for building collaborative recommender systems
Collaborative filtering plays the key role in recent recommender systems. It uses a user-item preference matrix rated either explicitly (i.e., explicit rating) or implicitly (i.e., implicit feedback). Despite the explicit rating captures the preferences better, it often results in a severely sparse matrix. The paper presents a novel iterative semi-explicit rating method that extrapolates unrate...
متن کاملTowards a participatory E-learning 2.0 A new E-learning focused on learners and validation of the content
Our aim is to propose a collaborative methodological approach centred on learners and based on the Web 2.0 tools in order to make E-learning 2.0. It is based on a process consisting of four iterative steps which are: grouping, collaborating, validating and publishing content. In this context, learners will be the creators of the content of assigned courses in a virtual meeting through the chat....
متن کاملAutomatic Tag Recommendation for the Web 2.0 Blogosphere Using Collaborative Tagging and Hybrid ANN Semantic Structures
This paper proposes a novel approach to automatic tag recommendation for weblogs/blogs. It makes use of collective intelligence extracted from Web 2.0 collaborative tagging as well as word semantics to learn how to predict the best set of tags to use, using a hybrid artificial neural network (ANN). The use of “tags” has recently become very popular as a mean of annotating and organizing everyth...

The present study explored the effect of a pedagogical blog on Iranian EFL learners’ creative and critical thinking skills using a mixed-methods approach. In the pedagogical blog, the researchers asked learners divergent and evaluative questions based on Lindley’s model (1993). The quantitative data were collected by administering Creativity Test Questionnaire (ATC) and ...

Cold start is one of the main challenges in recommender systems. Solving sparsechallenge of cold start users is hard. More cold start users and items are new. Sine many general methods for recommender systems has over fittingon cold start users and items, so recommendation to new users and items is important and hard duty. In this work to overcome sparse problem, we present a new method for rec...
