Techniques in Text Mining The application of techniques from different areas such as Information Extraction, Information Retrieval, Natural Language Processing(NLP), Query Processing, Categorization and Clustering. All these stages of Text Mining process can be combined into a single workflow. Figure 1: Techniques in Text Mining Information Extraction Information Extraction is the process of extracting information from unstructured document using the techniques. The main objective
been done for many languages and to serve many of purposes like politics, social services, movie reviews…etc., but unfortunately there is no work has been done for Arabic language. In the following we browsing some of these works: OSVision Opinion Mining [6] is an automatic system which can extract opinions from the Web. The system uses advanced natural language processing algorithms for extracting opinion, the system is supported by machine learning approaches and knowledge representations which
thousands of records. However, free-form text comments are more difficult to summarize. Sorting and categorizing these opinions is called sentiment analysis. Companies already spend resources to research customer satisfaction and sentiment analysis is a great research tool for consumers and business. Sentiment is one’s attitude or opinion about something. Sentiment analysis uses various research areas such as natural language processing, data mining, and text mining to discover the consumer’s opinion
With multitudes of information shared on social media websites like Twitter, Facebook etc and discussions about company offerings on blogs, forums and posts; companies want to extract every bit of the information available to analyze consumer sentiments about their offerings. Companies from different domains are trying to use the customer sentiment information to gain a competitive edge in business. Below are some common industries that use sentiment analysis. Examples of companies within the domain
research institutes, and technology intensive companies. Data mining provides a solution for this problem. A. Data Mining Data mining emerged in 1980 for creating the useful information. Data mining is used to extract useful patterns and previously unknown trends from the large databases.The overall goal of the data mining process is to extract information from a data set and transform it into an understandable structure for further use. Data mining has various techniques such as classification, clustering
for exploration companies such as those involved in the mining industry. Although the Global Business Standard codex, as highlighted by Pain et al (2005), discusses eight underlying ethical principles, in this paper, our focus will be on only three of these which are listed as follows; reliability, dignity, and fairness principles. By analyzing each of these three principles, this paper will effectively evaluate business conduct in the mining industry. The Dignity Principle This principle is based
From the 1850’s – 1900’s gold, silver, lead and zinc were discovered in South and West Australia. In the early 20th century mining started to decline because the only major finds were lead, zinc and copper but their full potential was later realized. Today Australia is one of the leading nations in the mining industry as they have a lot of resources to mine. Australia’s lead history: Lead is one of the oldest metals known to man. Lead was the first discovery out of all metals in Australia. The
“Erzulie”, a short story written by Pauline Melville, illustrates an important theme in Caribbean literature. The story is an example of literature that uses a strong theme of nature in the text and displays environmental symbolism throughout. The main theme in Caribbean literature is seen as the struggles of indigenous people and the consequences they face after the islands were colonized, however other themes such as post-colonial environmental harm can be seen in stories such as “Erzulie”.

In Mining OSHA defines asbestos as a fiber that includes six different types of minerals such as chrysotile, amosite, crocidolite, tremolite, anthophyllite, and actinolite. Asbestos is actually known for its heat resistance and insulating properties in which is designed for everything such as fire-proof vests and brake pads to home and commercial construction. But our primary concern is that asbestos is the carcinogenic potential of airborne fibers. Asbestos is a critical toxin in the mining field

2.2 Sand mining and gravel extraction in the world Sand mining and gravel extraction are a worldwide activity in both developed and developing countries as was realised by Draggan (2008). Industrial sand and gravel are produced, processed and used in construction and industry all over the world. The leading nations in mining and processing sand and gravel are the United States of America, Australia, Austria, Belgium, Brazil, India, Spain, Nigeria, Kenya and South Africa. As a cheap and readily accessible
The graves of the necropolis were built between 4700 and 4200 BC, indicating that gold mining could be at least 7000 years old. Gold is a chemical element with symbol Au and atomic number 79. In its purest form, it is a bright, slightly reddish yellow, dense, soft, malleable, and ductile metal. Chemically, gold is a transition metal and a
rocks and minerals that are mined in throughout Colorado. Rocks and minerals can be mined underground and some of them are pit mines. I live in Western Colorado where there are several different mining operations of rocks and minerals. Gold, silver, gypsum, and marble mines. I will describe the different mining techniques, economic advantages and disadvantages, as well as how the rock or minerals are shipped. Marble Colorado, is located in the Rocky Mountains that was incorporated in 1899. The town
There are many problems that would require a geologist to solve ranging from erosion of the soil, volcanic activity, seismic faults, rocks and plate tectonics and why the continents are moving, sinkholes and many others. One current problem that I have witnessed and read about from multiple sources is about sinkholes. In the past few years there have been many occurrences where sinkholes are occurring and causing a huge amount of damage to the environment; and have also cause many casualties. Sinkholes
Mining is the process or industry of obtaining minerals from the earth. Topics in this paper I’ll be specifically discussing are pros and cons of mining, structures of a mine, mining in general, California gold rush, diamonds in Africa, and comparison of diamond and gold mines. A person must have a general understanding of mining to really Cite at end of paragraphs (author’s name, page number) Mining in General Most people don’t know the difference from a hanging wall and footwall. A footwall is
when the curtains are unveiled, and the truth is shown. Where are the ethical principles which hold this industry together? A shovel is dug back into the ground, the wind blows onto the small particles of dirt, revealing the business conduct of the mining industry, but the ethical principles have been crushed just like how the rocks of the earth have been crushed, for they have not turned into gold, nor diamonds, nor rubies, these ethical principles of business conduct have been forgotten away in the
Homer Hickam was a teenage boy from a mining town in West Virginia called Coalwood. He inspired to build rockets when he seen the first artificial satellite, Sputnik, streak across the stars. With his friends and the local nerd, Homer sets out to do just that but with many errors and trials. Along with the town, Homer's father thought they were wasting their time with their rockets. He wanted Homer to be a coal miner just like everyone else but Homer knew he didn't belong there. As time went on,
also detail how coal is located through to the process of how coal is mined in particular open-cut mining. I am also going to evaluate the advantages and disadvantages of coal usage and mining. how coal is extracted from the ground, we will also be looking at a flow chat about the steps of an open-cut mining in progress, the disadvantages and advantages of consumption of coal and if overall coal mining good, bad or important. Coal is a sedimentary rock that is mostly made up of carbon, hydrogen,
