This paper proposes an SNS and Web Data Analytics System which can utilize a business marketing strategy by analyzing negative SNS and Web Data that can do great damage to a business image. It consists of the Data Collection Module collecting SNS and Web Data, the Hbase Module storing the collected data, the Data Analysis Module estimating and classifying the meaning of data after an semantic analysis of the collected data, and the PHS Module accomplishing an optimized Map Reduce by using SNS and Web data involved a Businesse. This paper can utilize this analysis result for a business marketing strategy by efficiently managing SNS and Web data with these modules.

In this paper, we suggest a plan to take advantage of the SNS data to proactively identify the information on crime risk factor and to prevent crime. Recently, SNS(Social Network Service) data have been used to build a proactive prevention system in a variety of fields. However, when users are collecting SNS data with simple keyword, the result is contain a large amount of unrelated data. It may possibly accuracy decreases and lead to confusion in the data analysis. So we present a method that can be efficiently extracted by improving the search accuracy through text mining analysis of SNS data.

Social network service (SNS) related data including comments/text, images, videos, blogs, and user experiences contain a wealth of information which can be used to build recommendation systems for various clients' and provide insightful data/results to business analysts. Multimedia data, especially visual data like image and videos are the richest source of SNS data which can reflect particular region, and cultures values/interests, form a gigantic portion of the overall data. Mining such huge amounts of data for extracting actionable intelligence require efficient and smart data analysis methods. The purpose of this paper is to focus on this particular modality for devising ways to model, index, and retrieve data as and when desired.

최근 데이터의 범람과 더불어 빅데이터 시대가 도래 하면서 SNS 라는 새로운 플랫폼을 마케팅에 활용하고자 하는 기업들이 늘어나고 있다. 기업들은 이러한 SNS 상의 데이터를 분석하고 이를 공개 API 를 통해 마케팅에서 활용할 수 있다. 하지만 SNS 업체들은 과도한 트래픽 유발 및 보안상의 이유로 공개 API 의 사용을 제한하고 있다. 따라서 제한된 사용 횟수 안에서 효과적으로 공개 API 를 사용할 수 있는 고객맞춤 최적화가 필요하다. 기존의 멀티캐스팅을 이용하면 이러한 고객맞춤 최적화가 가능하지만 SNS 의 특성을 반영한 것이 아니기 때문에 SNS 마케팅에서 활용하는데에는 한계가 있을 수 밖에 없다. 본 논문에서는 이러한 멀티캐스팅을 이용한 고객맞춤 최적화의 한계를 보완하고 SNS 의 특성을 보다 잘 활용할 수 있는 새로운 SNS 마케팅을 위한 고객맞춤 최적화를 제시한다.

SNS(Social Network Service)는 새로운 소통수단으로 인적 네트워크뿐만 아니라 사회, 문화 등에 많은 영향을 미치고 있다. 특히, 무선인터넷과 스마트폰의 보급으로 정보유통량이 기하급수적으로 증가하면서, 데이터를 처리 및 분석하는 것이 화두가 되고 있다. 본 논문에서는 급증하는 SNS 데이터를 처리 및 분석하여 의미 있는 데이터를 키워드 중심으로 추출하고자 하였다. 이를 위해 기존 데이터 처리방식이 아닌 빅데이터 처리에 적합한 MapReduce 환경에서 SNS 데이터를 필터링하고, 토픽을 예측하기 처리방법을 제시하였다. 또한, 웹 서비스를 기반으로 구현하여 분석된 데이터를 시각적으로 표현하고, 재생산하였으며, 실험을 통해 제안하는 처리방법의 성능을 검증하였다.

The opinion mining technique which analogize significant information from SNS message is increasingly important because opinions communicated through SNS are increasing. This paper propose SEIAS(SNS Emotional Information Analysis Strategy) based on opinion mining that analogize emotional information from SNS setting a different weight according to position of antonym and adverb. Firstly, the proposed SEIAS constructs a emotion dictionary for opinion mining analysis, Secondly, it collects SNS data on real time, compare it with emotion dictionary and calculates opinion value of SNS data. Specially, it increases the precision of opinion analysis result compared to the existing SO-PMI because it sets up the different value according to the position of antonym and adverb when it calculates the opinion value of data.

As a diverse range of smartphones has been recently developed and diffused, the users of SNS (Social Network Service) also have been sharply increased. The SNS saves a variety of information such as exchanged pictures and videos, voice mails or location sharing, chat history, etc. as well as simple user data, so that the acquisition of data that are useful in the aspect of digital forensic is achievable. This thesis reviews the types of SNS that are available for the iPhone, a recent example of highly used smartphones, and types of data by each client. Also, efficient data analysis method for digital forensic investigations is suggested by analyzing the relationships within the collected data by each client.

As Internet technology develops, SNS users are increasing. As SNS becomes popular, SNS-type crimes using the influence and anonymity of social networks are increasing day by day. In this paper, we propose a fake account classification method that applies machine learning and deep learning to statistical and image data for fake accounts classification. SNS account data used for training was collected by itself, and the collected data is based on statistical data and image data. In the case of statistical data, machine learning and multi-layer perceptron were employed to train. Furthermore in the case of image data, a convolutional neural network (CNN) was utilized. Accordingly, it was confirmed that the overall performance of account classification was significantly meaningful.

최근 SNS(social networking service)의 사용이 급증함에 따라 SNS에서 발생하는 데이터의 분석이 활발해졌다. 하지만 SNS 데이터는 빠르게 생성되며 정형화 되어 있지 않은 빅데이터이기 때문에 그대로 수집할 경우 분석하기가 어렵다. 본 논문은 분산 스트리밍 처리 기술인 Storm을 사용하여 트위터에서 실시간으로 발생하는 데이터를 수집 및 집계하고, 태그 클라우드를 사용하여 집계 결과를 동적으로 시각화하고자 한다. 또한 사용자가 쉽게 키워드를 입력하고 시각화 결과를 실시간으로 확인할 수 있도록 웹 인터페이스를 구현한다. 그리고 결과를 통해 태그 클라우드의 결과가 시간에 따라 바르게 시각화되었는지 확인한다. 본 논문은 빠르게 발생하는 SNS 데이터로부터 각 키워드와 관련된 정보를 시각화하여 각 사용자에게 제공할 수 있는 우수한 결과가 사료된다.
