An important part of our information-gathering behavior has always been to ﬁnd out what other people think.With the growing availability and popularity of opinion-rich resources such as online review sites and personal blogs, new opportunities and challenges arise as people now can, and do, actively use information technologies to seek out and understand the opinions of others. The sudden eruption of activity in the area of opinion mining and sentiment analysis, which deals with the computational treatment of opinion, sentiment, and subjectivity in text, has thus occurred at least in part as a direct response to the surge of interest in new systems that deal directly with opinions as a ﬁrst-class object.

This survey covers techniques and approaches that promise to directly enable opinion-oriented informationseeking systems. Our focus is on methods that seek to address the new challenges raised by sentimentaware applications, as compared to those that are already present in more traditional fact-based analysis.We include material on summarization of evaluative text and on broader issues regarding privacy, manipulation, and economic impact that the development of opinion-oriented information-access services gives rise to. To facilitate future work, a discussion of available resources, benchmark datasets, and evaluation campaigns is also provided.
According to the U.S. Department of Labor, Bureau of Labor Statistics, mining and geological engineers, including mining safety engineers are expected to have 10 percent employment growth between 2006 and 2016. This is about as fast as the average for all occupations. Following a lengthy period of decline, strong growth in demand for minerals and increased use of mining engineers in the oil and gas extraction industry is expected to create some employment growth over the 2006-16 period. Moreover, many mining engineers currently employed are approaching retirement age, a factor that should create additional job openings. Furthermore, relatively few schools offer mining engineering programs, resulting in good job opportunities for graduates. The best opportunities may require frequent travel or even living overseas for extended periods of time as mining operations around the world recruit graduates of U.S. mining engineering programs.
Earnings for engineers vary significantly by specialty, industry, and education. Even so, as a group, engineers earn some of the highest average starting salaries among those holding bachelor's degrees.

Almost all jobs in engineering require some sort of interaction with coworkers. For example, some mining engineers work with geologists and metallurgical engineers to locate and appraise new ore deposits. Whether they are working in a team situation, or just asking for advice, most engineers have to have the ability to communicate and work with other people.
Engineers should be creative, inquisitive, analytical, and detailoriented. They should be able to work as part of a team and to communicate well, both orally and in writing. Communication abilities are important because engineers often interact with specialists in a wide range of fields outside engineering.
The type of job a mining engineer has will often determine whether how much they work inside or outside. Many mining engineers work to solve problems related to land reclamation and water and air pollution, which will cause them to visit sites for evaluation. While some desk work is likely, most mining engineers will spend a good deal of time on job sites. There are international travel opportunities for some mining engineers, as their expertise is needed on a global basis. Some mining engineers work on a consulting basis, and may spend most of their time in an office. Opposed Jet Mill
