Improving claim analytics through text mining
 
03:11
Text mining provides a means of extracting new information from unstructured data. Milliman's Phil Borba uses text mining to examine accident descriptions and can thereby identify instances of distracted driving—including cell phone use, radio use, and other distractions—that might not otherwise be visible. This is but one example of how text mining can extract hidden meaning that was not previously available to property and casualty insurers.

Statistical Text Analysis for Social Science
 
01:04:01
What can text analysis tell us about society? Corpora of news, books, and social media encode human beliefs and culture. But it is impossible for a researcher to read all of today's rapidly growing text archives. My research develops statistical text analysis methods that measure social phenomena from textual content, especially in news and social media data. For example: How do changes to public opinion appear in microblogs? What topics get censored in the Chinese Internet? What character archetypes recur in movie plots? How do geography and ethnicity affect the diffusion of new language? In order to answer these questions effectively, we must apply and develop scientific methods in statistics, computation, and linguistics. In this talk I will illustrate these methods in a project that analyzes events in international politics. Political scientists are interested in studying international relations through *event data*: time series records of who did what to whom, as described in news articles. To address this event extraction problem, we develop an unsupervised Bayesian model of semantic event classes, which learns the verbs and textual descriptions that correspond to types of diplomatic and military interactions between countries. The model uses dynamic logistic normal priors to drive the learning of semantic classes; but unlike a topic model, it leverages deeper linguistic analysis of syntactic argument structure. Using a corpus of several million news articles over 15 years, we quantitatively evaluate how well its event types match ones defined by experts in previous work, and how well its inferences about countries correspond to real-world conflict. The method also supports exploratory analysis; for example, of the recent history of Israeli-Palestinian relations.

Writing is an iterative process comprising exploratory, drafting, revising, and editing stages. This technology assists writers by doing most of the hard work during the exploratory stage. Relevant papers in the literature are automatically discovered and presented to the writers in visually-appealing forms to aid the exploration process.

IU X-Informatics Unit 21:Web Search and Text Mining 2: Web and Document/Text Search-The Problem I
 
08:21
Lesson Overview: This lesson starts with the web with its size, shape (coming from the mutual linkage of pages by URL's) and universal power laws for number of pages with particular number of URL's linking out or in to page. The way Web search is performed by users is discussed. Information retrieval is introduced and a possible DIKW mapping for web search is given. A comparison is given between semantic searches as in databases and the full text search that is base of Web search. The ACM classification illustrates potential complexity of ontologies. Some differences between web search and information retrieval are given. Enroll in this course at https://bigdatacourse.appspot.com/ and download course material, see information on badges and more. It's all free and only takes you a few seconds.

Normality test using SPSS: How to check whether data are normally distributed
 
09:15
If data need to be approximately normally distributed, this tutorial shows how to use SPSS to verify this. On a side note: my new project: http://howtowritecitations.com. Statistical analyses often have dependent variables and independent variables and many parametric statistical methods require that the dependent variable is approximately normally distributed for each category of the independent variable. Let us assume that we have a dependent variable, exam scores, and an independent variable, gender. In short, we must investigate the following numerical and visual outputs (and the tutorial shows how to do just that): -The Skewness & kurtosis z-values, which should be somewhere in the span -1.96 to +1.96; -The Shapiro-Wilk p-value, which should be above 0.05; -The Histograms, Normal Q-Q plots and Box plots, which should visually indicate that our data are approximately normally distributed. Remember that your data do not have to be perfectly normally distributed. The main thing is that they are approximately normally distributed, and that you check each category of the independent variable. (In our example, both male and female data.) Step 1. In the menu of SPSS, click on Analyze, select Descriptive Statistics and Explore. Step 2. Set exam scores as the dependent variable, and gender as the independent variable. Step 3. Click on Plots, select "Histogram" (you do not need "Stem-and-leaf") and select "Normality plots with tests" and click on Continue, then OK. Step 4. Start with skewness and kurtosis. The skewness and kurtosis measures should be as close to zero as possible, in SPSS. In reality, however, data are often skewed and kurtotic. A small departure from zero is therefore no problem, as long as the measures are not too large compare to their standard errors. As a consequence, you must divide the measure by its standard error, and you need to do this by hand, using a calculator. This will give you the z-value, which, as I said, should be somewhere within -1.96 to +1.96. Let us start with the males in our example. To calculate the skewness z-value, divide the skewness measure by its standard error. All z-values in the tutorial video are within ±1.96. We can conclude that the exam score data are a little skewed and kurtotic, for both males and females, but they do not differ significantly from normality. Step 5. Check the Shapiro-Wilk test statistic. The null hypothesis for this test of normality is that the data are normally distributed. The null hypothesis is rejected if the p-value is below 0.05. In SPSS output, the p-value is labeled "Sig". In our example, the p-values for males and females are above 0.05, so we keep the null hypothesis. The Shapiro-Wilk test thus indicates that our example data are approximately normally distributed. Step 6. Next, let us look at the graphical figures, for both male and female data. Inspect the histograms visually. They should have the approximate shape of a normal curve. Then, look at the normal Q-Q plot. The dots should be approximately distributed along the line. This indicates that the data are approximately normally distributed. Skip the Detrended Q-Q plots. You do not need them. Finally, look at the box plots. They should be approximately symmetrical. The video contains references to books and articles. About writing out the results: I would put it under the sub-heading "Sample characteristics", and the video contains examples of how I would write. In this tutorial, I show you how to check if a dependent variable is approximately normally distributed for each category of an independent variable. I am assuming that you, eventually, want to use a certain parametric statistical methods to explore and investigate your data. If it turns out that your dependent variable is not approximately normally distributed for each category of the independent variable, it is no problem. In such case, you will have to use non-parametric methods, because they make no assumptions about the distributions. Good luck with your research.

Candle volume charts are among the easiest to use for predicting intraday price fluctuations. These charts use the capability of both the candlestick price chart and the volume chart. You could look at learning some common candlestick patterns if you are into that style of trading. Bollinger bands are another statistical trend tool that chartists use to predict intraday price charts. The candlestick chart shows the day high, the day low, the opening price and the closing price for each of the previous trading days. Volume stats are added to the candlestick chart to tell traders of the pressure behind every price tick. It, too, comes with many electronic trading softwares. Bollinger bands indicate the upper and lower thresholds at which the current price is likely to fluctuate. It uses the price trend from the past 20 days to make that prediction. The upper and lower bands are only estimates, but they are indicative of price points that can infer a bullish or bearish trend if crossed. Never you can’t predict next candlestick why because at least many traders trade in 5 minutes or 15 mnts in intraday buy myself and my student trade in 3 minutes candlestick this 3 minutes is just for entry candlestick pattern doesn’t works in this 3 minutes but comparing with volume,channels and levels you can find a right entry with small stop loss so learn and earn on your own. how to find support and resistance levels how to identify support and resistance levels in forex support and resistance charts free stock support and resistance website support and resistance indicator support and resistance zones bac support and resistance levels support and resistance calculator excel candlestick charting psychology candlestick psychology candle charting psychology candlestick psychology pdf how to read candle wicks candlestick math pdf mastering candlestick math predicting next candlestick candlestick secrets candlestick patterns candlestick patterns explained with examples #how_to_predict_next_candlestick #candlestick_psychology

What Is Statistics: Crash Course Statistics #1
 
13:00
Welcome to Crash Course Statistics! In this series we're going to take a look at the important role statistics play in our everyday lives, because statistics are everywhere! Statistics help us better understand the world and make decisions from what you'll wear tomorrow to government policy. But in the wrong hands, statistics can be used to misinform. So we're going to try to do two things in this series. Help show you the usefulness of statistics, but also help you become a more informed consumer of statistics. From probabilities, paradoxes, and p-values there's a lot to cover in this series, and there will be some math, but we promise only when it's most important. But first, we should talk about what statistics actually are, and what we can do with them. Statistics are tools, but they can't give us all the answers.

The Promise of Digital Books: Dominique Raccah at TEDxNaperville
 
14:37
Could society actually be on the brink of a paradigm shift on how we use books? Will digital actually make us read more than ever before? And how will the way we read change? In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)

Keyword Proximity Search on XML Graphs
 
11:02
Keyword search provides a user-friendly information dis- covery mechanism for web users to easily access XML data without the need of learning a structured query language or studying possibly complex and evolving data schemas. How- ever, due to the lack of expressivity and inherent ambiguity, there are two main challenges in performing keyword search on XML data intelligently. 1. First, unlike XQuery, where the connection among data nodes matching a query is speci¯ed precisely using variable bindings and where clauses, we need to au- tomatically connect the keyword matches in a mean- ingful way. 2. Second, unlike XQuery, where the data nodes to be returned are speci¯ed using a return clause, we should e®ectively identify the desired return information. Several attempts have been made to address the ¯rst chal- lenge [3, 2, 9, 7] by selecting and connecting keyword matches through a variant concept of lowest common ancestor, named as VLCA (such as SLCA [9], MLCA [7], interconnection [2], etc.). However, it is an open problem of how to automat- ically and e®ectively infer return nodes, the names of the data nodes that are the goal of user searches. There are two baseline approaches for determining return nodes adopted in the existing work. One is to return the subtrees rooted at VLCA nodes [3, 9], named as Subtree Return. Alternatively, we can return the paths in the XML tree from each VLCA node to its descendants that match an input keyword, as described in [1, 4], named as Path Return. However, neither approach is e®ective in identifying return information as the following examples show. Let us look at the sample queries listed in Figure 2 on XML data in Figure 1(a). For Q1, it is likely that a user is interested in the information about Rockets. Both Subtree Return and Path Return ¯rst compute the VLCA of keyword matches, which is the match node itself: Rockets (0.2.0.0), then output this node. However, to echo print the user FOR MORE INFORMATION VISIT US AT http://www.seocertification.org.in/ http://www.seocertification.org.in/seo-training.php http://www.seocertification.org.in/sem-training.php http://www.seocertification.org.in/ppc.php http://www.seocertification.org.in/books.php http://www.seocertification.org.in/online-examination.php

NCBI Minute: Using EDirect to Query a Local Installation of PubMed
 
26:31
Presented June 13, 2018. Data mining in PubMed may require the analysis of thousands of records. The E-utilities efetch service often limits your ability to retrieve large numbers of records in a short time. As you will see in this webinar, EDirect allows you much faster access by operating on a local copy of PubMed. EDirect includes an archive-pubmed script that fully automates the download, update, extraction, and storage process. EDirect's Local Data Cache uses a hierarchy of 1 million folders to organize the 28 million PubMed files and provides direct and rapid access to any record. These features use recent advances in computer file system technology to repackage all of PubMed as individual files on an inexpensive 500 gigabyte external solid state drive. In this webinar, you will learn how to use EDirect to install PubMed locally and then search and retrieve records from the local instance. You will also see an analysis example that shows the significant speed improvement with the Local Cache and employs some advanced EDirect xtract options to aid with processing records.

And here we have the variable car color, where we have 15 different cars that were observed ; as people drove by, someone noted the color of the car. And what I've done in this example is I've already entered my value labels so, for example, if I click this button right up here [the value labels button is clicked], then I'll see the colors that the different numbers correspond to. So notice that we have 4 white cars that were observed and so forth. I'm going to turn the value label off for now, but you'll see how they're very useful in a moment when we produce a bar graph. To produce a bar graph in spss, let's go to analyze and then descriptive statistics and, we can actually use the frequencies command to produce a bar graph, and the we can also use the graphs command - I'll show you both ways. To produce a bar graph using the frequencies procedure, go to Analyze, and then Descriptive Statistics, and then Frequencies, and then you should see your window open and it should look like this. I'm going to move car color over to the variables box, select charts, and then here we want to select bar chart, click continue. Let's deselect the display frequencies table and then click OK. Notice here we get a bar chart where the variable is car color on the x-axis, the frequency is on the y-axis. We have our different car colors here and the height of the bar indicates the frequency or how many of each color car was observed. So we have 2 black cars were observed, 4 white cars, 6 blue cars, 2 red cars, and 1 green car. Now, many of the options on this chart can be modified, and I'll show you one quick modification we can do. If I double-click on this chart, what will happen is the chart editor will open as you see here, and I'm going to double-click on any of these bars. When I do that the properties dialog box opens. Let's go ahead and go to fill and border (click on that tab); and I'll select this blue color right here and then click apply. Then close this window out. Notice what happened here -- now my bars are blue. This is one of the many options that can be modified in our charts. Let's go ahead and close this out -- so click X -- now we have our chart and notice the blue color has been applied. As I said at the beginning I was going to show you how to obtain this exact same chart using the graphs menu command in spss. To do so, select Graphs, and then Legacy Dialogs, and then Bar. Now here a bar chart dialog box opens; I want to leave the default options in place. So just click define. You should see a window like this with car color on the left. Go ahead and move that to the category axis box and then click ok. You should see that this gives us the exact same bar chart with the only exception that I haven't modified the color to be blue. In summary, we saw how to obtain a bar chart using two different approaches -- both the frequencies procedure and the graphs legacy dialog command. This concludes the tutorial on obtaining a bar chart in SPSS. Channel Description: For step by step help with statistics, with a focus on SPSS. Both descriptive and inferential statistics covered. For descriptive statistics, topics covered include: mean, median, and mode in spss, standard deviation and variance in spss, bar charts in spss, histograms in spss, bivariate scatterplots in spss, stem and leaf plots in spss, frequency distribution tables in spss, creating labels in spss, sorting variables in spss, inserting variables in spss, inserting rows in spss, and modifying default options in spss.

DEZL Digital Marketing Solutions
 
04:50
DEZL Digital Marketing Solutions Deborah Petersen Enrico Suarez Zack Tysiak Logan Watson-Page OBJECTIVE: Increase exposure, awareness, and sales to executives in India and the Greater Toronto Area who are interested in a fishing & dining adventure. 0:48 Solution 1: Weekly Videos Details: Each week, a representative of the business will upload videos to YouTube and link them on their social media pages. The videos will provide tips, advice, and answers to potential questions for those who are interested in cottage-life. Some examples would be Q and A’s (addressing any questions received via social media, e-mail, their webpage, etc.), tips on packing for a vacation, advice on fishing gear/lures, virtual tours of the cottages, etc. This type of content will help the business to build a relationship with potential consumers and give them an idea of the types of things they would be able to enjoy if they book a package. Why: Virtual reality is becoming increasingly popular as a marketing tool, so incorporating some virtual tours into video content may set these videos apart from others on the market. Videos are popular on social media and may have a more positive effect and likelihood of being viewed by consumers than just photos or text. Another aspect worth mentioning is the popularity of YouTube videos among Gen X’ers, whose top 3 interests for video content is nostalgic/past events, current events, and learning/how-to videos (McGee, 2017). When it comes to millennials, building an experience is crucial to gaining their attention, whereas Gen X is all about the practicality of their purchase, which are both something that these videos offer (Richardson, 2018). The number of likes, shares, and comments will indicate the effectiveness of the videos and provide a means of measurability. 1:48 Solution 2: Spin to Win Giveaway Details: When a consumer clicks the link, they will be brought to a sub-page on the company’s website with a Spin to Win Giveaway. The consumer clicks a wheel which spins and randomly selects a giveaway option. Each wedge has a different value, like 5, 10, or 15% off their booking with one of the twelve being a 25% off wedge. Codes for each value will be unique and be provided after the consumer inputs their e-mail. The codes may be used via the website or in-person when booking. We will be able to measure its effectiveness by how many discount codes are actually used by customers. Why: This type of interactive content will help increase web traffic to the business’ page which will increase awareness. Consumers enjoy interactive content, and by including a discount code, it will also help promote sales. Whether it is through an e-mail, social media post, or a giveaway, offering a discount is a great incentive for customers to choose this business over a competitor’s, and if their experience is as good as advertised, they may even become repeat customers (Tanase, 2018). 2:58 Solution 3: Email Blasts Details: Encourage consumers to register for e-mail subscriptions through social media platforms such as Linkedin and Facebook. Our target market is for executives and high-end customers, which typically includes older generations as they are likely to hold executive positions with higher income levels. There are high percentages of executives using Linkedin (Andreou, 2018, p. 26), and according to Statistica, 15% of Indians use Linkedin and 30% use Facebook. (Statista, 2018). Another important consideration is that e-mail is the most widely used means of communication on the internet for older people with “93% of baby boomers (1946-1964) actively using email, and 61% of them [using] it on a daily basis” (Andreou, 2018, p.79). Why: By combining social media as a means of advertising we can measure outcoming links by having post that links to our main page that consumers can use to register for weekly news flyers and potential deals (discounts, free stay, etc.). On the website’s main page, it could also be altered so that consumers can buy packages online as “75% of baby boomers buy products online” (Andreou, 2018, p.80). Using Google Analytics to see who registers and compare bounces would provide a means of measurability (Andreou, 2018, p. 31 and p.86).

Calculating Descriptive Statistics in Excel
 
01:33
For numerical data with one or more variables, descriptive statistics are used to summarize the empirical distribution of each variable. Windows Excel can calculate descriptive statistics using the Data Analysis Toolpak, which you should already have enabled as an add-in for Excel. First, start Excel and open your data set. I will assume that your data is arranged with the variables as columns and that your data also includes column headings. Next, click the Data tab and choose Data Analysis. If you do not see the Data Analysis option here, then you have not enabled the Data Analysis Toolpak correctly. In the next box, select Descriptive Statistics and click OK. You will then be presented with a dialog box requiring several inputs. For the Input Range, select the rectangular array of cells around the numerical columns that you would like to analyze. Click that labels are in the first row, and be sure to click the option for Summary Statistics. Other options can safely be left at their defaults. Then click OK. After a moment, Excel will produce a new tab with the desired descriptive statistics.

Did you check the weather forecast? Busted! Did you decide to go through the drive through lane vs walk in? Busted again! We are constantly creating hypotheses, making predictions, testing, and analyzing. Our lives are full of probabilities! Statistics is related to probability because much of the data we use when determining probable outcomes comes from our understanding of statistics.

Data mining
 
47:46
Data mining (the analysis step of the "Knowledge Discovery in Databases" process, or KDD), an interdisciplinary subfield of computer science, is the computational process of discovering patterns in large data sets involving methods at the intersection of artificial intelligence, machine learning, statistics, and database systems. 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. Aside from the raw analysis step, it involves database and data management aspects, data pre-processing, model and inference considerations, interestingness metrics, complexity considerations, post-processing of discovered structures, visualization, and online updating. The term is a misnomer, because the goal is the extraction of patterns and knowledge from large amount of data, not the extraction of data itself. It also is a buzzword, and is frequently also applied to any form of large-scale data or information processing (collection, extraction, warehousing, analysis, and statistics) as well as any application of computer decision support system, including artificial intelligence, machine learning, and business intelligence. The popular book "Data mining: Practical machine learning tools and techniques with Java" (which covers mostly machine learning material) was originally to be named just "Practical machine learning", and the term "data mining" was only added for marketing reasons. Often the more general terms "(large scale) data analysis", or "analytics" -- or when referring to actual methods, artificial intelligence and machine learning -- are more appropriate.

Advanced Content Marketing Strategy (Step-By-Step) | A Look Into Neil Patel's Brain
 
59:32
Get a look into the mind of Neil Patel as he breaks down his personal content marketing process. ►Subscribe: https://goo.gl/ScRTwc to learn more secret SEO tips. Find me on Facebook: https://www.facebook.com/neilkpatel/ Read more on my blog: https://neilpatel.com/blog We're here to kick off the Advanced Content Marketing Summit. In this session, Neil will show the audience everything he does on his own sites, analytics, driving traffic, a bunch more. So, let's get that screen sharing up. Give us just a few seconds. Let's first get started in my analytics. I think it's already loaded. So, audience overview. You guys can see my traffic stats. There's not really much to hide. So last seven days, I was at 214,000 unique visitors. That's not too shabby, considering I don't do paid advertising. There was like, two jumps. So this is August. Let's look at August of last year, 2016. Keep in mind, I was also doing paid ads then. I was at 454. Now I'm at 200-something thousand in seven days, right? You guys see the difference? Like, you know, this is August 2016. This is, I don't know, we can do a whole month like July. So, 454. I look at users, 'cause users is unique. So 454 to 695. So my traffic is still growing, and here's one strategy that I did. It's hard to see when I look at these months, but if you look at last year, so we can pick any day. Like, we can pick October 2016, and let's go into some of my blog posts. The site content, all pages. So you see this? 13 secrets that'll boost your Facebook organic reach. This post has 13,404 visits. So we would take these keywords. I would sort 'em by impressions and click the rate. So, I can see which keywords have the highest impression count. Like, Facebook marketing strategy gets a ton of impressions for being on the eighth page. 80 position, 80.8, is usually eighth or ninth page, right, however you wanna look at it. So when I would look at all of this, I would sort by impressions, and then I would take all of these keywords, and I would integrate 'em within my blog post. So, let's go to my post. And this post is now changed. It's not 13. Facebook organic reach, search post. My editor is in there; Grant is currently editing. Okay, you see it's now called 20 Secrets That'll Boost Your Facebook Organic Reach, versus the old one of 13 secrets. In other words, what I did is I took this post and I made it super detailed, and I added in all the keywords. It works really well each and every single time. So, the page is loading, and I'll show you other examples that I did this way. Right, like, as you can see, and then I create a table with the list, where you can just click, and you can go down to the section, right, and I'm integrating the keywords within the content. The page is super long. If you look at how many keywords now, this post has 9,858 keywords, or technically words. Some of 'em are a keyword rank, some of 'em aren't, and that's how I rank better, is by modifying the articles and adding in all the keywords that do well, or that I'm at least getting impressions for. Then that way, I know what Google's already ranking me for. If I discuss those topics within my content, I'm much more likely to get ranking. And I do this for a lot of my content pieces. I go through Google Search Console. Every single week, we go and we figure out, all right, what are the most popular posts that we're ranking for, and we just continually rewrite those articles. That's what is helping increase our traffic and our rankings more than anything else. So, if I go month over month, keep in mind, August isn't over yet. So I go to like, April. I know we weren't doing it all the way back in April, and I go to today. August, of course, is gonna be lower than July, because August isn't over yet, but as you can see, it's pretty much growing, right? April, 15, then 12. June is when we rewrote the article, some time in June. July was our first full month, and like, look, it's just going up. July, already, July first through 31st, 22,000 visits. July first to August 23rd, 21,000 visits. That shows, so 21,498. 21,498 divided by, let's say 23rd, Clayton? That puts us on track or 28,000 visitors this month. That's not too shabby, right, all because we rewrite the post and just put in more keywords.
