Abstract

In this paper, we propose a method to detect spam tweets containing unhealthy information by using an n-gram dictionary under limited labeling. Spam tweets that contain unhealthy information have a tendency to use similar words and sentences. Based on this characteristic, we show that spam tweets can be effectively detected by applying a Naive Bayesian classifier using n-gram dictionaries which are constructed from spam tweets and normal tweets. On the other hand, constructing an initial training set requires very high cost because a large amount of data flows in real time in a twitter. Therefore, there is a need for a spam detection method that can be applied in an environment where the initial training set is very small or non exist. To solve the problem, we propose a method to generate pseudo-labels by utilizing twitter's retweet function and use them for the configuration of the initial training set and the n-gram dictionary update. The results from various experiments using 1.3 million korean tweets collected from December 1, 2016 to December 7, 2016 prove that the proposed method has superior performance than the compared spam detection methods.

본 논문에서는 트레이닝 데이터가 제한된 환경에서 n-gram 사전을 이용하여 불건전 정보를 포함하는 스팸 트윗을 탐지하는 방법을 제안한다. 불건전 정보를 포함하는 스팸 트윗은 유사한 단어와 문장을 사용하는 경향이 있다. 이러한 특성을 이용하여 스팸 트윗과 정상 트윗에 대한 n-gram 사전을 구축하고 나이브 베이스 분류기를 적용하여 효과적으로 스팸 트윗을 탐지할 수 있음을 보인다. 반면에, 실시간으로 대용량의 데이터가 유입되는 트위터의 특성은 초기 트레이닝 집합 구성에 매우 큰 비용을 요구 한다. 따라서, 초기 트레이닝 집합이 매우 작거나 존재하지 않는 환경에서 적용할 수 있는 스팸 트윗 탐지 방법이 필요하다. 이를 위해 트위터의 리트윗 기능을 활용하여 의사 라벨을 생성하고 초기 트레이닝 집합의 구성과 n-gram 사전 업데이트에 활용하는 방법을 제안한다. 2016년 12월 1일부터 2016년 12월 7일까지 수집된 한국어 트윗 130만 건을 사용한 다양한 실험 결과는 비교 방법들보다 제안하는 방법의 성능이 우수함을 입증한다.
