An I try to test this code:
library(tidytext)
library(stringr)
reg <- "([^A-Za-z_\\d##']|'(?![A-Za-z_\\d##]))"
tidy_df <- df %>%
filter(!str_detect(text, "^RT")) %>%
mutate(text = str_replace_all(text,
"https://t.co/[A-Za-z\\d]+|http://[A-Za-z\\d]+|&|<|>|RT|https",
"")) %>%
unnest_tokens(word, text, token = "regex", pattern = reg) %>%
filter(!word %in% stop_words$word,
str_detect(word, "[a-z]"))
But I receive this error:
Error in stri_detect_regex(string, pattern, opts_regex = opts(pattern)) :
argument `str` should be a character vector (or an object coercible to)
Is there any problem with the input data and this error happens? What can I do to fix it?
You forgot to load dplyr (library(dplyr)). This causes R to use stats::filter() rather than dplyr::filter(). The former function has a different signature and does not expose free_text to the inner str_detect().

As you can see, I was able to remove "\r\n-" occurring after "Flexible work-life benefits" while "-" from those first few "\r\n-" still remained.

Anyone has any idea what is the problem and how do I go about it? I have tried using another function pdf_text() from pdftools package but it yielded the same frustrating result. At first I thought "-" for the first few "\r\n-" is slightly longer than the latter ones but the direct copy-paste attempt seems to contradict this observation. Is there something "hidden" in the object which is not migrated during the copy-paste action? Any suggestions is greatly appreciated!
I found a likely answer to my question. It seems the original extracted text from the PDF document is not in an encoding that R Studio could recognise. This would explain why for the first few "-"s were not removed. After I apply jd_text <-iconv(jd_text,"UTF-8") to coerce the encoding to UTF-8, my problem was solved, and I am able to remove "\r\n-" completely.

I run a monthly report which tracks session views by region, most popular knowledge articles, deflection rates, most popular product pages, software download stats, etc.
We have a new ELT member who is keen to get into the numbers around our contact centre. As I only look after the support site I need only concern myself with putting together a report which outlines what I feel will be useful information around web traffic. I want the report to be brief, and to highlight 4-5 key metrics.
Please can I have some suggestions for data you think would be useful given the target audience?
So far I am considering:
Deflection rates
Bounce rates.
Time on page
Most popular software downloads.
Global session views year to date.
Any help would be really appreciated. Thanks!
I think those metrics are great. Ideally, the value in the data comes from slicing your metrics with a dimension, ie pivoting. For example, bounce rate as an average means little whereas bounce rate by Content Group or Device Category would be more interesting.
Speaking of Device Category, consider completely isolating the metrics for Mobile vs Desktop+Tablet. Those experiences are so drastically different you'd be doing a disservice to average those metrics together.
Lastly, I'd say this new ETL member should get their own access to GA and learn how to pull the data need. GA now offers machine learning insights that quickly surface relevant drivers in metrics; a static approach to KPI reporting is becoming increasingly obsolete.
Basically I was looking to use stripe to take online payments for an online lottery website however the application is marked as a prohibited business.
Prohibited Businesses: Gambling
Lotteries; bidding fee auctions; sports forecasting or odds making; fantasy sports leagues with cash prizes; internet gaming; contests; sweepstakes; games of chance
Alternative Options??
I was looking for another option instead of stripe that would take online payments for my application.
It is a startup business so i would like the payment option to handle the merchant bank account side like stripe/paypal.
The project is being developed on asp.net, web forms c#.
Any advice would be greatly appreciated.
Most countries are regulating gambling of any form.
A few examples:
some countries like France have a company dealing with such purpose under the authority of the government.
for US, gambling regulation is different by state, and some don't even allow Lottery at all.
in Ireland, latest laws allows online gambling, prior to acquire a license delivered by the state. Not having this license can cost up to €300,000 as a fine.
There is a good chance that your Lottery application will fall under the same regulation, in which case you have to contact whichever authority in your country to ask them how you can create a gambling application under required law, if permitted (keeping in mind that this could be a pretty tedious and long process).
Bottom line of your question:
Stripe or other online payment systems are not allowing these types of payments because of this regulation.
Even if passing the barrier of regulation, a lot of technical restrictions would have to be applied to verify people residence to avoid legal issues.
UPDATE:
One option as mentioned in comments would be to use Bitcoin (using it with ASP.NET) as an alternative money to circumvent legal issues, but that doesn't mean that this is not regulated yet or going to be in a near future (which falls legally under a Lacuna).
I am developing a school management system and I am struggling whether I should develop for [desktop app + wcf] or web app(website). Which one is going to be the best for the given scenario?
The main goals for the “Integrated Web-Based School Management and Quality Audits Software Project for Secondary Schools are outlined below. In addition, specific objectives within each of the goals have been provided.
Goal 1: To facilitate automated data entries in secondary schools
Objective 1:1- To provide internet facilities and computer systems for secondary schools to further facilitate entries of student information into an integrated school management system.
Objective 1:2- To provide teachers with the possibility to enter continuous assessment data into the computer systems for each student.
Objective 1:3- To provide teachers with the possibility to enter end of term results for each student.
Objective 1:4:- To provide teachers with the possibility to enter students’ conduct at end of term for each student
Objective 1:5:- To provide the administration office with the possibility to register new students into the system
Objective 1:6:- To provide finance/fees office with the possibility to enter fees information for each student
Objective 1:7:- To provide parents with the possibility to access their children’s information online and provide feedback when needed or requested to do so
Goal 2:- To generate a portfolio of student information in respect of each student. A unique student identification will be used to access each student’s portfolio. The following are the main components of the portfolio.
Objective 2:1:- One of the components of the students’ portfolio page will be the Result Slip of the immediate last examination term. This will display all subjects taken by the student, continuous assessment results, examination results, grades and positions obtained in each subject, overall student position, student’s conduct and recommendation information. This report will automatically be gathered from the various inputs made from the individual teachers and staff
Objective 2:2:- Up to date historical record of Fees Information. This is vital information that will be available on each student portal. All fees due and all payments made that are entered by the fees/finance staff will be gathered by this component of the portfolio. Parents will be able to see this as well and provide feedback on any observed discrepancies.
Objective 2:3:- Attendance and Conduct report. This component of the portfolio is intended to give an account of the student’s attendance records and information on conduct as provided by the school authorities. If the information demands parent’s attention and feedback, this will be indicated here, and parents will be able to enter relevant feedback as requested.
Objective 2:4:- Completed and Pending Assignments Module. This component of the student’s portfolio will list all assignments completed by the student in the current term and will list uncompleted ones as well.
Goal 3:- To generate aggregated data for the management of the school. This will enable the school management have a high-level overview of student population, performance statistics for all the modules in the various classes, aggregated data on fees paid and fees pending, etc. There will hyperlinks or select options from which authorized staff will click or select from, in order to reach the requested aggregated data. Main components of the management page are listed below,
Objective 3:1:- One of the components of the staff portfolio page will be the Population Statistics. This will indicate total number of students, which is expandable to also list number of males and number of females. This can further be expanded to list female and male students in the various classes
Objective 3:2:- Performance Overview is another component of the staff portfolio. This will provide a high level overview of students’ performance. Per each class and for each subject, this module will list the number of Grade A students, Grade B students and so on and so forth. This links can be further expanded to view the number of males and females who obtained the various grades in the various classes. This module will also compare grades obtained in one subject with another to give an overview of modules that students do very well with those that they do not, to help management take quick action to rectify any anomalies
Objective 3:3:- Fees Overview is another component of the staff portfolio. This will provide fees information in the form of total fees paid within a specific period (Selectable from term, year, previous year(s), all years until current term, etc.). This information can be further expanded to show fees owed per class, payments overdue and allow the fees office to generate generic reminder messages in the form of email or text messages to parents of students who are overdue.
Reading through those requirements, it sounds like this is more than one application.
Undoubtedly you need some sort of web application (probably ASP.NET in some form?) to allow the parents of students to asses their children's records.
However for security purposes this same application should probably not be used for teachers and administrative staff to edit these records. Those functions should be on a protected LAN, and require more application security for viewing or editing any potentially sensitive data (especially financial records).
I don't see where WCF would fit into this, unless you need to provide some web service support to some other system? Or perhaps proving some "application server" on a protected LAN that can use WCF to serve data to 2 separate applications for outside / public access (from separate web servers in a DMZ) and one for internal users.
There isn't really 1 answer to this question.
You said "I am struggling whether I should develop for [desktop app + wcf] or web app(website)", but it sounds like you need to develop the [desktop app + wcf] anyway because the school administration is already using some sort of desktop application to update the data. You also need a web application for the parents to view their children's record. If you can, I strongly suggest you skip the wcf and just do a web application. At my current job, there's something similar to what rally25rs describe, and it is a pain in the ass to maintain the desktop application, the asp.net website and the wcf service business logic. But it sounds like you have no choice, so good luck!
