kandi X-RAY | mark Summary
Mark Notation or simply Mark, is a new unified notation for both object and markup data. The notation is a superset of what can be represented by JSON, HTML and XML, but overcomes many limitations of these popular data formats, yet still having a very clean syntax and simple data model.

QUESTION
I would like to extract the definitions from the book The Navajo Language: A Grammar and Colloquial Dictionary by Young and Morgan. They look like this (very blurry):
I tried running it through the Google Cloud Vision API, and got decent results, but it doesn't know what to do with these "special" letters with accent marks on them, or the curls and lines on/through them. And because of the blurryness (there are no alternative sources of the PDF), it gets a lot of them wrong. So I'm thinking of doing it from scratch in Tesseract. Note the term is bold and the definition is not bold.
How can I use Node.js and Tesseract to get basically an array of JSON objects sort of like this:
...ANSWER
Answered 2021-Jun-15 at 20:17Tesseract takes a lang variable that you can expand to include different languages if they're installed. I've used the UB Mannheim (https://github.com/UB-Mannheim/tesseract/wiki) installation which includes a ton of languages supported.
To get better and more accurate results, the best thing to do is to process the image before handing it to Tesseract. Set a white/black threshold so that you have black text on white background with no shading. I'm not sure how to do this in Node, but I've done it with Python's OpenCV library.
If that font doesn't get you decent results with the out of the box, then you'll want to train your own, yes. This blog post walks through the process in great detail: https://towardsdatascience.com/simple-ocr-with-tesseract-a4341e4564b6. It revolves around using the jTessBoxEditor to hand-label the objects detected in the images you're using.
Edit: In brief, the process to train your own:
- Install jTessBoxEditor (https://sourceforge.net/projects/vietocr/files/jTessBoxEditor/). Requires Java Runtime installed as well.
- Collect your training images. They want to be .tiffs. I found I got fairly accurate results with not a whole lot of images that had a good sample of all the characters I wanted to detect. Maybe 30/40 images. It's tedious, so you don't want to do TOO many, but need enough in order to get a good sampling.
- Use jTessBoxEditor to merge all the images into a single .tiff
- Create a training label file (.box)j. This is done with Tesseract itself.
tesseract your_language.font.exp0.tif your_language.font.exp0 makebox - Now you can open the box file in jTessBoxEditor and you'll see how/where it detected the characters. Bounding boxes and what character it saw. The tedious part: Hand fix all the bounding boxes and characters to accurately represent what is in the images. Not joking, it's tedious. Slap some tv episodes up and just churn through it.
- Train the tesseract model itself
- save a file:
font_propertieswho's content isfont 0 0 0 0 0 - run the following commands:
tesseract num.font.exp0.tif font_name.font.exp0 nobatch box.train
unicharset_extractor font_name.font.exp0.box
shapeclustering -F font_properties -U unicharset -O font_name.unicharset font_name.font.exp0.tr
mftraining -F font_properties -U unicharset -O font_name.unicharset font_name.font.exp0.tr
cntraining font_name.font.exp0.tr
You should, in there close to the end see some output that looks like this:
Master shape_table:Number of shapes = 10 max unichars = 1 number with multiple unichars = 0
That number of shapes should roughly be the number of characters present in all the image files you've provided.
If it went well, you should have 4 files created: inttemp normproto pffmtable shapetable. Rename them all with the prefix of your_language from before. So e.g. your_language.inttemp etc.
Then run:
combine_tessdata your_language
The file: your_language.traineddata is the model. Copy that into your Tesseract's data folder. On Windows, it'll be like: C:\Program Files x86\tesseract\4.0\tessdata and on Linux it's probably something like /usr/shared/tesseract/4.0/tessdata.
Then when you run Tesseract, you'll pass the lang=your_language. I found best results when I still passed an existing language as well, so like for my stuff it was still English I was grabbing, just funny fonts. So I still wanted the English as well, so I'd pass: lang=your_language+eng.

QUESTION
I have run a topology, and I used the Meter type in metric Reporting API v2. In the execute method I mark this metric. So it will mark an event whenever the execute method is called. But when I compare this value with the __execute-count, I see huge differences. Does anyone know why this happens?
These are the values from my log which are gathered at the same time:
9:v7 __execute-count {v0:v7=44500}
9:v7 tuple_inRate.count 664129
Update: When I use the mark method on the Meter metric, I will get different results in comparison with the Counter metric. But still, I do not understand why the values from the counter metric (tuple counter) are not the same as the __execute-count.
...ANSWER
Answered 2021-Jun-11 at 06:51As given in this answer, Storms Internal Metrics are just estimated by a percentage of the real data flow. Initially, it uses 5% of incoming tuples to make those estimations. This may lead to inaccuracies for extreme high or low throughputs.
EDIT: The documentation describes the following:
In general all of these tuple count metrics are randomly sub-sampled unless otherwise stated. This means that the counts you see both on the UI and from the built in metrics are not necessarily exact. In fact by default we sample only 5% of the events and estimate the total number of events from that. The sampling percentage is configurable per topology through the topology.stats.sample.rate config. Setting it to 1.0 will make the counts exact, but be aware that the more events we sample the slower your topology will run (as the metrics are counted in the same code path as tuples are processed). This is why we have a 5% sample rate as the default.
EDIT 2 In this post, there is more information about the estimation:
The way it works is that if you choose a sampling rate of 0.05, it will pick a random element of the next 20 events in which to increase the count by 20. So if you have 20 tasks for that bolt, your stats could be off by +-380.
By the way, execute_count is just an increasing number, while your tuple_inRate.count is a rate, isn`t it?
QUESTION
Overview
I am trying to tabulate time over days under Google Sheets and see each person's availability based on their start and end times which changes almost every week.
File Information I have this Sample Availability Timesheet with two Sheet-Tabs.
Master Sheet-Tab: This Sheet-Tab contains the list of employees with their respective start-time & end-time.
Availability Sheet-Tab: This Sheet-Tab contains the list of employees and a timescale with one hour hop. The resource availability is marked with Y, and by N if the resource is not available using the following formula:
...ANSWER
Answered 2021-Jun-15 at 14:04Updated formula:
=IF(VALUE(VLOOKUP($A2, Master!$A:$M, 13, 0)) > VALUE(VLOOKUP($A2, Master!$A:$M, 12, 0)), IF(ISBETWEEN(B$1, VALUE(VLOOKUP($A2, Master!$A:$M, 12, 0)), VALUE(VLOOKUP($A2, Master!$A:$M, 13, 0))), "Y", "N"), IF(OR(B$1 <= VALUE(VLOOKUP($A2, Master!$A:$M, 13, 0)), B$1 >= VALUE(VLOOKUP($A2, Master!$A:$M, 12, 0))), "Y", "N"))
Screenshot from the sheet you've shared with the formula working:
This version is an extension of the formula you shared. If someone is working from 4PM to 2AM then the way IFBETWEEN is being used will throw an error because 2AM is numerically less than 4PM and hence there is nothing in between.
So in cases where someone starts at a PM time and ends at AM time the formula checks for all slots between 12AM and the person working AM and marks them a Y. At the same time the formula also checks for all times in PM that are greater than the person working PM and marks them a Y as well.
If the person starts at a PM time and ends at a greater PM time then it uses your initial version of the formula.
I have made a slight modification to your formula and it should work now.
=IF($C9>$B9, IF(ISBETWEEN(B$1, VLOOKUP($A2, $A$8:$C, 2, 0), VLOOKUP($A2, $A$8:$C, 3, 0)), "Y", "N"), IF(OR(B$1 <= VLOOKUP($A2, $A$8:$C, 3, 0), B$1 >= VLOOKUP($A2, $A$8:$C, 2, 0)), "Y", "N"))
Please remember to remove the dates from some of the cells ex in your sheet the value in C2 is 12/31/1899 2:00:00 and it should be changed to just 2:00:00.
