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.

“…Companies engaging customers should capitalize on this need by ensuring communications provide a feeling of connection or belonging. Time commitment, reader intensity, such as blogging or "Retweeting," and willingness to engage the organization are several ways a company can measure effectiveness (Li et al, 2014). Typical users often willingly engage with organizations they have an interest in, make it important for organizations to be selective about the platforms they use (Li et al, 2014).…”

Abstract. Many people have embraced social media (SM), including both personal and professional uses. Corporations hoping to capitalize on this indoctrination are seeking to understand ways they can engage in SM. One possible idea is disseminating financial results. This topic emerged as a result of the recent decision by the Securities and Exchange Commission granting permission. A problem for company leadership is the lack of understanding of the potential SM has to enhance shareholder value. Little research exists today on the impact of a corporate policy to use social web to announce dividend or earnings statements on shareholder value. This research studied SM platforms for financial communications on stock price. By calculating cumulative abnormal returns, researchers learned the impact of SM for financial disclosures. The sample size included thirty-four publicly traded American financial institutions. This research seeks to advance understanding of financial statement dissemination using SM.

“…In addition, the contract then also has its legal effects. In many legal systems, the time of formation of a contract may have critical impact in reporting certain issues such as determining the moment the offeror loses his right to withdraw the offer, the right of the offeree to withdraw its acceptance, the time of the transfer of ownership of the goods and the transfer of its sequent destruction or damage in the case of the sale of certain goods (Ramokanate, 2014), and the price which has many consequences of the trade in international stock exchanges (Li, Xie, Chen, Wang, & Deng, 2014).…”

The use of technology is dominant, creating new challenges against the existing legal systems in Iraq.
