“…An effective way of increasing customer satisfaction and consequently customer loyalty has been done that has helped the customers identify products according to their interests. This again has called for the provision of personalized product recommendations [8,9]. Hofmann and Puzicha in their work have used the Latent Class Model (LCM) to circumvent the aforementioned problems.…”

“…It has been pointed out that direct marketing is a promotion process which has motivated customers to place orders through various channels [6,9]. In order to work for this, one is needed to have an accurate customer segmentation based on a good understanding of the customers, so that relevant product information can be delivered to different customer segments.…”

The user generated content on the web grows rapidly in this emergent information age. The evolutionary changes in technology make use of such information to capture only the user's essence and finally the useful information are exposed to information seekers. Most of the existing research on text information processing, focuses in the factual domain rather than the opinion domain. In this paper we detect online hotspot forums by computing sentiment analysis for text data available in each forum. This approach analyses the forum text data and computes value for each word of text. The proposed approach combines K-means clustering and Support Vector Machine with PSO (SVM-PSO) classification algorithm that can be used to group the forums into two clusters forming hotspot forums and non-hotspot forums within the current time span. The proposed system accuracy is compared with the other classification algorithms such as Naïve Bayes, Decision tree and SVM. The experiment helps to identify that K-means and SVM-PSO together achieve highly consistent results.

“…Nowadays, researchers are also using combined approaches, in which two or more approaches are combined to achieve better accuracy. Sindhwani and Melville [16] presented a unified framework in which lexical background information, unlabeled data, and labeled training examples can be effectively combined. Li et al [17] set up a system to analyze the market impact by combining the stock price and news sentiment.…”

The dramatic increase in the use of smartphones has allowed people to comment on various products at any time. The analysis of the sentiment of users' product reviews largely depends on the quality of sentiment lexicons. Thus, the generation of highquality sentiment lexicons is a critical topic. In this paper, we propose an automatic approach for constructing a domain-specific sentiment lexicon by considering the relationship between sentiment words and product features in mobile shopping reviews. The approach first selects sentiment words and product features from original reviews and mines the relationship between them using an improved pointwise mutual information algorithm. Second, sentiment words that are related to mobile shopping are clustered into categories to form sentiment dimensions. At each sentiment dimension, each sentiment word can take the value of 0 or 1, where 1 indicates that the word belongs to a particular category whereas 0 indicates that it does not belong to that category. The generated lexicon is evaluated by constructing a sentiment classification task using several product reviews written in both Chinese and English. Two popular non-domain-specific sentiment lexicons as well as state-of-the-art machine-learning and deep-learning models are chosen as benchmarks, and the experimental results show that our sentiment lexicons outperform the benchmarks with statistically significant differences, thus proving the effectiveness of the proposed approach.

Abstract:Nowadays, there exists a broad development in utilizing Internet in long range internet in social networking (communication (e.g., texting, video collections, and so forth.), social insurance, online business, bank exchanges, and numerous different administrations. These Internet applications require a palatable level of security and protection. Then again, our computers are under assaults and defenseless against numerous dangers. There is an expanding accessibility of apparatuses and traps for assaulting and intruding networks. Anomalous exercises in social organizations speak to abnormal and unlawful exercises showing distinctive practices than others exhibit in a similar structure. This paper talks about various sorts of abnormalities and their novel order in view of different qualities. A survey of number of procedures for avoiding and distinguishing anomalies alongside fundamentalsuppositions and explanations behind the nearness of such inconsistencies is shrouded in this paper. The paper displays an audit of number of data mining approaches used to recognize anomalies. Keywords:Anomalous activity, anomalies, Data mining techniques, Review analysis, Social Networking I.INTRODUCTION Anomaly detection alludes to recognizing designs in a given informational collection that don't fit in with a set up typical conduct. The examples subsequently identified are called anomalies and mean basic and significant data in a few application spaces. Anomalies are likewise alluded to as anomaly, astonishment deviation and so on. Most anomaly recognition calculations require an arrangement of simply typical information to prepare the model and they certainly expect that inconsistencies can be dealt with as examples not seen some time recently. Since an exception might be characterized as an information point which is altogether different from whatever is left of the information, in view of some measure, we utilize a few discovery conspires to perceive how proficiently these plans may manage the issue of outlier recognition. The measurements group has concentrated the idea of exceptions broadly. In these methods, the information focuses are displayed utilizing a stochastic appropriation and focuses are resolved to be anomalies relying on their association with this model. However with expanding dimensionality, it turns out to be progressively troublesome and erroneous to evaluate the multidimensional appropriations of the information focuses [1]. However recent anomaly discovery calculations that we use in this review depend on figuring the full dimensional separations of the focuses from each other and in addition on processing the densities of nearby neighborhoods. The deviation measure is our augmentation of the customary technique for anomalies recognition. As in anomalies identification, correlations are made amongst anticipated and genuine sensor values, and contrasts are deciphered to be signs of anomalies. This crude disparity is gone into a standardization procedure indistinguishable to that utilized for the...
