Checking a Video File
Next, you'll watch a video from start to finish and check the codes, formatting, and decide whether you agree with the annotations that are in the file.

Navigate to the following file:
Open the .opf in Datavyu. Use Add Data and navigate to the video file (use the unscrubbed version):
Click Save As and save with your initials (HG_27_12_sparse_code.opf). Then, open up the word document in the same folder called "27_12_Video_Coding_Issues.docx" and read the information from past coders. You can save a new version of this, as well, with your initials. Take notes here about issues you find in the file or segments that you change significantly from the original.
Use the Datavyu shortcuts on the number pad to move through the video. Things to check for each word:
Is the word coded correctly, spelled right, and a concrete, imageable noun?
Do you agree with the sentence type, object presence, and speaker codes?
If there is Personal Information, is it properly marked, according to these rules?
If you add any new Personal Information cells, you will need to notify lab staff by assigning them a task called "[file name] video scrub"
If there are CHI utterances, do they have corresponding %pho cells?
New %pho cells should be formatted as a point cell immediately after the CHI cell, with the codes reading "%pho:[space][three number signs with no spaces in between], NA, NA, NA"
Do all comment cells have onsets and offsets? Are those onsets and offsets identical?
Do the timestamps of the words capture the entire utterance? If not, extend the onset or offset to capture the word and the sentence.
In the bottom left corner of the Datavyu spreadsheet window, there is a "Favorites" folder for scripts. Check to see that this is set to a directory called "datavyu_scripts" and if it is, double click on "run_all_postannotation.rb". This will tell you if you have any formatting errors in your spreadsheet.
When you're finished, you'll need to merge your changes with the previous version of the file's Basic Level.
Export the file from Datavyu as a .csv and save the .csv with your initials in the subfolder within check_files/video called "basic_level_for_wordmerge". Save your file as "HG_27_12_sparse_code_processed.csv"
Open your processed .csv and in the first cell of Column H, write "labeled_object.basic_level"
Save your .csv
Open Terminal or Git Bash.
These commands will update your scripts, if there have been any changes.
Next, you'll run wordmerge2 as a command line script. It takes three arguments
[1] the absolute path to the old basic level, usually found in Subject_Files/.../Home_Visit/Analysis/Video_Analysis, but for training, found in the directory specified below
[2] the absolute path to the new basic level: your processed .csv that should be in the same directory
[3] the absolute path to where you want the wordmerged .csv to appear, usually will be your Working File, but for training, it's the "basic_level_for_wordmerge" directory
You can write out the paths manually, or drag the appropriate files or folders into your Terminal window. File paths should have one space in between them.
Hitting enter should deposit a file called "HG_video_wordmerged.csv" into the "basic_level_for_wordmerge" folder.
This file will merge together changes that you made with the old basic level. If you added new words, it will put ***FIXME*** in the basic level column. If you changed something from a capital to a lower-case, or vice versa, it will put CASE in the basic level column.
A good mode of attack for checking the basic level is to highlight the whole sheet using this button in the top left corner of the spreadsheet:
Use Filter to add filters to your columns. Then, you can sort the basic level column by ascending alphabetical order. This will put the FIXME's at the top. Be careful when filling them in that you check the other instances of the word that might happen elsewhere in the file. Your new words could potentially shift the most common form from plural to singular or otherwise.
After you fix the CASE and FIXME's, re-sort by ascending alphabetical order in the basic level column and check all of the words. Use the Common Words Index for cases where you're unsure about what the basic level should be, or ask coworkers or lab staff.
Save your wordmerged .csv and notify lab staff that you've finished.
