Random Forest Classifier for News Articles Sentiment Analysis
Introduction DATA MINING It is the process to discover the knowledge or hidden pattern form large databases. The overall goal of data mining is to extract and obtain information from databases and transfer it into an understandable format for use in future. It is used by Business intelligence organizations, Financial analysts, Marketing organizations, and companies with a strong consumer focus like retail ,financial and communication . It can also be seen as one of the core process of knowledge discovery in data base (KDD). It can be viewed as process of Knowledge Discovery in database. Data Extraction/gathering:- To collect the data from sources . Eg: data warehousing. Data cleansing :- To eliminate bogus data and errors. Feature extraction:- To extract only task relevant data : i.e to obtain the interesting attributes of data . Pattern extraction and discovery :- This step is seen as process of data mining , where one should concentrate the effort. Visualization of the data and Evaluation of results :- To create knowledge base. CLASSIFICATION Classification is a technique of data mining to classify each item into predefined set of groups or classes. The goal of classification is to accurately predict the target class for each item in the data. For example, a classification model could be used to identify loan applicants as low, medium, or high credit risks. The simplest type of classification problem is binary classification. In binary classification, the target attribute has only two possible values: for example, high credit rating or low credit rating. Multiclass targets have more than two values: for example, low, medium, high, or unknown credit rating. SENTIMENT ANALYSIS Sentiment analysis is a sub-domain of opinion mining where the analysis is focused on the extraction of emotions and opinions of the people towards a particular topic. Sentiment analysis aims to determine the attitude of a speaker or a writer with respect to some topic. The attitude may be his or her judgment or evaluation, affective state (that is to say, the emotional state of the author when writing), or the intended emotional communication (that is to say, the emotional effect the author wishes to have on the reader). With opinion mining, we can distinguish poor content from high quality content. Random Forest Technique In this technique, a set of decision trees are grown and each tree votes for the most popular class, then the votes of different trees are integrated and a class is predicted for each sample. This approach is designed to increase the accuracy of the decision tree, more trees are produced to vote for class prediction. This approach is an ensemble classifier composed of some decision trees and the final result is the mean of individual trees results.

Qualitative analysis of interview data: A step-by-step guide
The content applies to qualitative data analysis in general. Do not forget to share this Youtube link with your friends. The steps are also described in writing below (Click Show more): STEP 1, reading the transcripts 1.1. Browse through all transcripts, as a whole. 1.2. Make notes about your impressions. 1.3. Read the transcripts again, one by one. 1.4. Read very carefully, line by line. STEP 2, labeling relevant pieces 2.1. Label relevant words, phrases, sentences, or sections. 2.2. Labels can be about actions, activities, concepts, differences, opinions, processes, or whatever you think is relevant. 2.3. You might decide that something is relevant to code because: *it is repeated in several places; *the interviewee explicitly states that it is important; *you have read about something similar in reports, e.g. scientific articles; *it reminds you of a theory or a concept; *or for some other reason that you think is relevant. You can use preconceived theories and concepts, be open-minded, aim for a description of things that are superficial, or aim for a conceptualization of underlying patterns. It is all up to you. It is your study and your choice of methodology. You are the interpreter and these phenomena are highlighted because you consider them important. Just make sure that you tell your reader about your methodology, under the heading Method. Be unbiased, stay close to the data, i.e. the transcripts, and do not hesitate to code plenty of phenomena. You can have lots of codes, even hundreds. STEP 3, decide which codes are the most important, and create categories by bringing several codes together 3.1. Go through all the codes created in the previous step. Read them, with a pen in your hand. 3.2. You can create new codes by combining two or more codes. 3.3. You do not have to use all the codes that you created in the previous step. 3.4. In fact, many of these initial codes can now be dropped. 3.5. Keep the codes that you think are important and group them together in the way you want. 3.6. Create categories. (You can call them themes if you want.) 3.7. The categories do not have to be of the same type. They can be about objects, processes, differences, or whatever. 3.8. Be unbiased, creative and open-minded. 3.9. Your work now, compared to the previous steps, is on a more general, abstract level. You are conceptualizing your data. STEP 4, label categories and decide which are the most relevant and how they are connected to each other 4.1. Label the categories. Here are some examples: Adaptation (Category) Updating rulebook (sub-category) Changing schedule (sub-category) New routines (sub-category) Seeking information (Category) Talking to colleagues (sub-category) Reading journals (sub-category) Attending meetings (sub-category) Problem solving (Category) Locate and fix problems fast (sub-category) Quick alarm systems (sub-category) 4.2. Describe the connections between them. 4.3. The categories and the connections are the main result of your study. It is new knowledge about the world, from the perspective of the participants in your study. STEP 5, some options 5.1. Decide if there is a hierarchy among the categories. 5.2. Decide if one category is more important than the other. 5.3. Draw a figure to summarize your results. STEP 6, write up your results 6.1. Under the heading Results, describe the categories and how they are connected. Use a neutral voice, and do not interpret your results. 6.2. Under the heading Discussion, write out your interpretations and discuss your results. Interpret the results in light of, for example: *results from similar, previous studies published in relevant scientific journals; *theories or concepts from your field; *other relevant aspects. STEP 7 Ending remark Nb: it is also OK not to divide the data into segments. Narrative analysis of interview transcripts, for example, does not rely on the fragmentation of the interview data. (Narrative analysis is not discussed in this tutorial.) Further, I have assumed that your task is to make sense of a lot of unstructured data, i.e. that you have qualitative data in the form of interview transcripts. However, remember that most of the things I have said in this tutorial are basic, and also apply to qualitative analysis in general. You can use the steps described in this tutorial to analyze: *notes from participatory observations; *documents; *web pages; *or other types of qualitative data. STEP 8 Suggested reading Alan Bryman's book: 'Social Research Methods' published by Oxford University Press. Steinar Kvale's and Svend Brinkmann's book 'InterViews: Learning the Craft of Qualitative Research Interviewing' published by SAGE. Text and video (including audio) © Kent Löfgren, Sweden

Literature Review Preparation Creating a Summary Table
This video shows you exactly how to create a summary table for your research articles. It outlines what information should go in the table and provides helpful summary hints. eBook "Research terminology simplified: Paradigms, axiology, ontology, epistemology and methodology" on Amazon: http://amzn.to/1hB2eBd OR the PDF: http://books.google.ca/books/about/Research_terminology_simplified.html?id=tLMRAgAAQBAJ&redir_esc=y http://youstudynursing.com/ Once you have found literature that you want to include in your review the task of summarizing it can be daunting. It is helpful to use a data extraction tool while you are reviewing each article. Then, creating a table that captures key points you need to consider for your analysis will make your summary more accurate, effective and complete. This step is so important that I get my students to do it for marks. If you are working on a literature review, trust me, you don't want to skip this step. If you do, the review will end up taking a lot longer to complete and you will be more likely to miss important information. Also, if you are working on a team these tables are absolutely essential for communication and collaboration. To set up your table, first identify the number of columns you think you will need. I usually start with seven. You can add more later if you need to, but I find it easier to remove information before publication than to add it. The headings in your table will depend on the information you need to collect, which depends on the purpose of your review. In this video I will go over the ones I recommend using as well as a few other helpful options. In the first column, always list the author and the year of publication. To make things easier, you will also want to save your articles in a folder on your hard drive by the author and year of publication. I will often also note the country that the study was conducted in. That way it is easy for me to quickly identify if more research is needed in my country specific to the topic of inquiry. You can also note the country later in the table. Discipline may also be useful to note either in the same column or a separate one if you are looking at a multi-disciplinary topic such as hand hygiene practices. It can help you identify if you need to consider looking in other areas to capture missing disciplines or if there is a lack of evidence particular to a discipline. However, if your literature review is focused on a particular discipline, such as nursing, than this information would not add anything to your table and should not be used. Remember to keep your table as concise as possible. Include the topic or focus of the study as well as the research purpose or research question in the next column. The focus of the article is absolutely critical to your summary table. Remember to be concise and specific. I also like to quote the purpose of the article here. Noting the conceptual or theoretical framework will help to inform you of the perspective the researchers are taking. You may also notice common ones that you could consider for your future research proposal. In any review it is important to note the paradigm and methods used. Typically, for first year students I only expect them to identify the paradigm as Qualitative or Quantitative. In upper years of the program and when I publish I expect a more specific identification of the methodology. Sometimes, depending on the purpose of the review, I use separate columns for the design, sampling method and data collection or analysis methods. For pragmatic reasons I still limit the total number of columns in my table to seven or eight. The context, setting and sample should also be noted. This is another location that the country that the study was conducted in can be listed. Just don't put the same information in two spots. Be concise and consistent. Whenever you are putting more than one type of information in a column make sure you are also consistent in the way and order it is listed. For example, always note the setting then the sample in this column. Use a bulleted list or separate information by paragraphs or periods. Key Findings need to be presented in a brief way. Make sure you are not simply writing everything down. What findings are of particular interest to the focus of your literature review? The more concise you are the better. Stay focused. Noting the gaps in the research will help you think about what research needs to be done. Make note of the limitations of the study you are reading as well as areas for future research. This step can be particularly useful when laying the foundation for your next research project. Many published reviews now include all or part of these summary tables. Go take a look at what has been published for more examples of how to construct your table. Music By http://instrumentalsfree.com

Mining Your Logs - Gaining Insight Through Visualization
Google Tech Talk (more info below) March 30, 2011 Presented by Raffael Marty. ABSTRACT In this two part presentation we will explore log analysis and log visualization. We will have a look at the history of log analysis; where log analysis stands today, what tools are available to process logs, what is working today, and more importantly, what is not working in log analysis. What will the future bring? Do our current approaches hold up under future requirements? We will discuss a number of issues and will try to figure out how we can address them. By looking at various log analysis challenges, we will explore how visualization can help address a number of them; keeping in mind that log visualization is not just a science, but also an art. We will apply a security lens to look at a number of use-cases in the area of security visualization. From there we will discuss what else is needed in the area of visualization, where the challenges lie, and where we should continue putting our research and development efforts. Speaker Info: Raffael Marty is COO and co-founder of Loggly Inc., a San Francisco based SaaS company, providing a logging as a service platform. Raffy is an expert and author in the areas of data analysis and visualization. His interests span anything related to information security, big data analysis, and information visualization. Previously, he has held various positions in the SIEM and log management space at companies such as Splunk, ArcSight, IBM research, and PriceWaterhouse Coopers. Nowadays, he is frequently consulted as an industry expert in all aspects of log analysis and data visualization. As the co-founder of Loggly, Raffy spends a lot of time re-inventing the logging space and - when not surfing the California waves - he can be found teaching classes and giving lectures at conferences around the world. http://about.me/raffy

Ep. 1: Finding a Research Direction
Recommended Citation: Tracy, S. J. [Get Your Qual On]. (2016). Making a difference with qualitative research [Video file]. Retrieved from https://youtu.be/tLu5IifevxM. For more information in formal text, see: Tracy, S. J. (2012). Qualitative research methods: Collecting evidence, crafting analysis, communicating impact. Hoboken, NJ: Wiley-Blackwell. Whenever you’re taking a qualitative methods course or embarking on a research project, one of the first questions often is, “What is my project going to be about?” “What am I going to study for the semester?” So oftentimes for the first couple assignments, you’re asked to come up with a ‘Research Topic.’ However, I’m here to tell you that that is not a great way to start! Because “topic” is so broad. You don’t want to do “topic” because it doesn’t tell you what’s interesting or important. So my recommendation instead is that you start with a ‘Research Problem’ -- and this is a shout-out to Stan Deetz who really was the one who brought this to my attention when I was a graduate student. So rather than starting like, for me, with this broad topic of “Emotion in Organizations,” I might start instead with a specific problem, like some people are being emotionally abused in an organization, or some people are burned out or stressed out, or some people are feeling like they have to fake their emotions and that is alienating themselves to other facets of themselves that aren’t the organizationally prescribed one. So when you start with a problem, the cool thing is is that you already have a rationale built in because if your research ends up shedding light on that issue, then you at least have some practice significance. That is a main thing that qualitative research can do is draw practical significance and help create organizations, institutions, families and so on so that they are flourishing and not just surviving. The other thing that I encourage folks to ask themselves is this question here: “How did you come to be[come] curious about [that topic]?” (Is that what I said? “How did you come to be curious about that?” So I need to learn how to read and do videos at the same time!) If you ask yourself how is it that you became curious, you get at what you are super passionate about. And we know that with any type of research when you do it well, systematically, there’s going to become times that it becomes boring and overwhelming and that you’re going to have to keep going even when it is super tough. So if you ask yourself from the get-go, “Why is it that I became interested in this topic?” you’ll figure out the angle that you’re most interested in. So if I say, “Why is it that I became interested in emotions and organizations?” I can go back to situations, for instance when I worked on the cruise ship and I felt like I was not able to express the entire set of facets of Sarah Tracy. I was only allowed to be the happy, excited person. Even when my grandmother died, I wasn’t allowed to grieve. By helping me know why I’m curious about it that helps drive the research design and it helps me realize, “Okay, in future research, I need to observe situations where maybe people are asked to maintain a sense of self that is different than other important senses of themselves,” or I need to ask interview questions where I say, “Are there times when you feel like you have a facade on? And if you’re wearing that facade, how is it that you find other ways to express other facets of yourself?” And so that really helps kind of narrow. So that’s it for this little video on “Finding a Research Direction.” Thanks!

This video shows how to import gene symbol data (CSV or tab separated) into Excel so that you can avoid introducing these errors. The video uses Excel 2016 for Mac but the same procedure can be done on Windows versions and previous Excel versions. View in 720P

YouTube Channel: https://www.youtube.com/user/statisticsinstructor Video Transcript: In this video we'll take a look at how to enter questionnaire or survey data into SPSS and this is something that a lot of people have questions with so it's important to make sure when you're working with SPSS in particular when you're entering data from a survey that you know how to do. Let's go ahead and take a few moments to look at that. And here you see on the right-hand side of your screen I have a questionnaire, a very short sample questionnaire that I want to enter into SPSS so we're going to create a data file and in this questionnaire here I've made a few modifications. I've underlined some variable names here and I'll talk about that more in a minute and I also put numbers in parentheses to the right of these different names and I'll also explain that as well. Now normally when someone sees this survey we wouldn't have gender underlined for example nor would we have these numbers to the right of male and female. So that's just for us, to help better understand how to enter these data. So let's go ahead and get started here. In SPSS the first thing we need to do is every time we have a possible answer such as male or female we need to create a variable in SPSS that will hold those different answers. So our first variable needs to be gender and that's why that's underlined there just to assist us as we're doing this. So we want to make sure we're in the Variable View tab and then in the first row here under Name we want to type gender and then press ENTER and that creates the variable gender. Now notice here I have two options: male and female. So when people respond or circle or check here that they're male, I need to enter into SPSS some number to indicate that. So we always want to enter numbers whenever possible into SPSS because SPSS for the vast majority of analyses performs statistical analyses on numbers not on words. So I wouldn't want and enter male, female, and so forth. I want to enter one's, two's and so on. So notice here I just arbitrarily decided males get a 1 and females get a 2. It could have been the other way around but since male was the first name listed I went and gave that 1 and then for females I gave a 2. So what we want to do in our data file here is go head and go to Values, this column, click on the None cell, notice these three dots appear they're called an ellipsis, click on that and then our first value notice here 1 is male so Value of 1 and then type Label Male and then click Add. And then our second value of 2 is for females so go ahead and enter 2 for Value and then Female, click Add and then we're done with that you want to see both of them down here and that looks good so click OK. Now those labels are in here and I'll show you how that works when we enter some numbers in a minute. OK next we have ethnicity so I'm going to call this variable ethnicity. So go ahead and type that in press ENTER and then we're going to the same thing we're going to create value labels here so 1 is African-American, 2 is Asian-American, and so on. And I'll just do that very quickly so going to Values column, click on the ellipsis. For 1 we have African American, for 2 Asian American, 3 is Caucasian, and just so you can see that here 3 is Caucasian, 4 is Hispanic, and other is 5, so let's go ahead and finish that. Four is Hispanic, 5 is other, so let's go to do that 5 is other. OK and that's it for that variable. Now we do have it says please state I'll talk about that next that's important when they can enter text we have to handle that differently.

Tour Of New Features In Newly Released DTube 0.6 📺 (The Cryptoverse)
Follow me on Steemit and earn crypto for your best comments: https://steemit.com/@marketingmonk The new and improved DTube, version 0.6 has just been launched so here is an easy to digest video tour of all the new features. https://about.d.tube/ So before we begin, let me not make any assumptions here, DTube is a decentralised rival for YouTube built on the Steem blockchain and IPFS technology. The combination of these two technologies means neither the data nor the video files are centrally hosted. This creates a one of a kind platform that allows people to earn cryptocurrency rewards, is resistant to censorship, has no ads AND is entirely open source. You find out more by going to about.d.tube but for now let’s begin the tour of all the new features in version 0.6. Also note that this is simply the video version of the official DTube 0.6 announcement post on Steemit. My thinking was that most people won’t be bothered to read it and DTube will not get enough appreciation. As a video, many more people will get the information and DTube will get the recognition it so dearly deserves. https://steemit.com/dtube/@heimindanger/d-tube-0-6-pushing-it-to-the-limit Growing By A Video A Minute At time of recording D.Tube has grown to the point where a new video is uploaded every minute! That gives you some perspective and destroys any notion that DTube is some theoretical project that is only being used by a handful of people. More Encoding Power For DTube to be usable by the average user they should have to put in as little effort as possible. That means the DTube system needs to take whatever video file you give it and then automatically process it behind the scenes into a format that everyone is able to view. DTube has grown so much since v0.5, 2 more dedicated servers have been brought online, just for encoding the videos. New Logo So now we have this new branding which is much better and much clearer. New Media Kit https://about.d.tube/mediakit.html Following on from the new logo, this forms part of the new DTube media kit, which was one of the most popular requests. This allows the DTube brand to appear consistently when people use it within their videos as well as opens up the possibility for you to create your own t-shirts, mugs and all other kind of merchandise bearing the DTube logo. Improved Loading Logic In this version of DTube when you click on a video the player will scan the IPFS network to find the copy of the file that has the fastest connection to you and then load it from there. This not only means the video will start playing faster when you first click on it, it should also play smoother and without interruptions. The video player is now also using a full custom design with a proper settings menu where you can change the speed at which the video plays. This is also where new settings can be added in future updates. Hotkeys The player now also responds to keyboard commands. Press space to play and pause the video. Press left and right arrow keys to go back 5 seconds or forward 5 seconds. If you press a number such as 5, it will jump to the 5 minute point. Frame Thumbnail Preview You’ll find another feature when it comes to scrubbing the timeline. When you hover your mouse of the timeline, you now get a thumbnail preview so you can find particular part of the video. Thumbnail Resizing We spoke earlier on about how DTube takes in all kind of different video files and then processed them into a universal format everyone can view. Well, DTube is now also doing that for pictures. Now, no matter if someone uploads a picture straight from their digital camera, DTube will resize the image to a small thumbnail so it loads super fast for the viewers but without the person uploading having to put in any effort. More than that though, DTube now only loads thumbnails that are in view. You can see this in action by visiting the hot videos page. Discovery One big drawback of DTube up until now was that unless you were already a super popular creator, you wouldn’t get in the hot or trending actions and thus would never be discovered. In this new version of DTube when you open up the side menu you will see there are now dedicated pages for, hot, trending and new videos. But there’s more. These pages are now infinitely scrollable, making it much more likely for smaller creators to get their videos found. Tag Browsing And speaking of discovering stuff… You can now browse Dtube by tags. Let’s say if we click on a video, we watched it, we liked it and wanted more of the same… You’ll notice that the tags are now listed right under the video player. So I just click on one of these and boom… I end up on another infinitely scrolling page full of videos that have this tag. And finally… if you need help with anything DTube related people use the DTube discord channel because that is now the official hub of the DTube community: https://discord.gg/dtube
