According to the increasing use of blogs, a huge number of posts have appeared in a blogosphere. This causes web surfers to face difficulty in finding the quality posts in their search results. As a result, post ranking algorithms are required to help web serfers to effectively search for quality posts. Although there have been various algorithms proposed for web-page ranking, they are not directly applicable to post ranking since posts have their unique features different from those of web pages. In this paper, we propose post ranking algorithms that exploit actions performed by bloggers. We also evaluate the effectiveness of post ranking algorithms by performing extensive experiments using real-world blog data.

The growth of blogs has two aspect of providing various information and marketing. This study collected the rankings of blog posts of large portal using OpenAPI and investigated the features of blogs ranked through the exploratory data analysis technique. As a result of the analysis, it was found that the influence of the blogger and the recent creation date of the post were highly influential factors in the top rank. Due to the weakness of these evaluation algorithms, there was a problem of showing the search results which is concentrated to the power blogger's post. In this study, we propose an algorithm that improves the reliability of content by adding the reliability DB information which is verified by the experts and reflects the fairness of the application of the ranking score through the trend index indicating various public interests. Improved algorithms have made it possible to provide more reliable information in the search results of the relevant field and have an effect of making it difficult to manipulate ranking by illegal applications that increase the number of visitors.

블로그는 개인의 생각을 온라인상의 문서인 포스트로 남기는 일종의 개인 홈페이지이다. 웹 문서와 포스트는 다른 특징을 가지고 있기 때문에 웹 문서 랭킹 알고리즘을 포스트에 적용하기에는 문제점이 존재한다. 본 논문에서는 포스트의 랭킹을 위한 포스트-블로거 그래프를 정의하고, 기존의 웹 문서 랭킹 알고리즘을 포스트-블로거 그래프에 적합하게 변형한 포스트 랭킹 알고리즘을 제안한다. 그리고 실제 블로그 데이터를 통하여 포스트 랭킹 알고리즘의 성능을 분석하고, 이를 바탕으로 블로그에 적합한 포스트 랭킹 알고리즘을 선별한다.

블로그 이용이 활성화됨에 따라 포스트 랭킹 방법의 필요성이 증가하고 있다. 기존 연구에서는 HITS 에 기반을 둔 포스트 랭킹 방법인 BAITS 와 BAITS 를 수정한 포스트 랭킹 방법들을 제안한바 있다. 본 논문에서는 이러한 포스트 랭킹 방법들을 다양한 척도를 이용한 비교 실험을 통해 비교하여 가장 정확도가 높은 랭킹 방법을 판별하고자 한다.
