Dedoose is an easy-to-use, collaborative, web based application that facilitates all types of research data management and analysis. Here's what you need to know about how to use it.
Working with Images
Working with PDFs as Images
PDFs can be prepared for excerpting in Dedoose by being processed as images or documents when uploaded to the project. Working with PDFs as images is much like single image files as described above.
Working with PDFs as Documents
PDFs can be prepared for excerpting in Dedoose by being processed as images or documents when uploaded to the project. Working with PDFs as a document is identical to text media files. The document-based importer runs the PDF through some Optical Character Recognition (OCR) technology in an attempt to convert the content to an in-line document. This approach is best suited when you wish to retain the searchable ability of text and have less concern about formatting. Once uploaded you will work with the content as a standard document as described in the 'Excerpting, Coding, and Weighting Text' section of this user guide.
Note that if the conversion within Dedoose is not satisfactory, our support team is happy to work with you and attempt to convert your files using other stand-alone software that can sometimes result in more desirable results.
The Media Workspace is where your media files are stored and you can find features to sort and manage these data.
Importing media files: You can import media in three ways:
Once you are presented with the import menu:
If you select a single text file, you will be taken directly to that file in document view within Dedoose.
If you select multiple text files, you will see a Success pop-up that indicates your documents have been uploaded.
For audio and video files, you will see a progress bar and then get a pop-up after the import indicating that the file has been added and is being processing in the background. You can continue to work elsewhere in Dedoose while this occurs, and when the file finishes processing, you will get a pop-up notifying you that it has completed. Finally, please keep in mind that the process of video files can take some time depending on the queue on our servers for processing these routines.
NOTE: It is important to be certain that your media are complete and any sensitive identifying information has been removed or changed before importing them to Dedoose. Within Dedoose, it is possible to unlock a document for editing, however this requires that all excerpts, coding activity, and linked memos that you have already applied will be deleted. (Dedoose is currently working on implementing the capability to edit documents while retaining previous work.)
TIP: When naming documents, it can be useful to implement a systematic and informative convention throughout your project. For example, the title '435MFGModerate' could be such a convention that represents cases with ID(number)Gender(Male or Female)Type(Focus Group, Interview, Observation)Socio-Economic Status(Low, Moderate, High)
TIP: When first uploading documents, it is often most efficient to immediately establish link(s) to descriptors, if appropriate, so these important relationships are not neglected. However, this may not always be possible if descriptor data have not yet been created. In any case, these links can be established or changed at any time by click the 'Descriptors' button (see below).
To manually add a document to Dedoose:
The Media Workspace has features for sorting your media files, customizing column views, and filtering by sub-group using Boolean operators. Using these features can be a quick way to locate or review sets of media files in your project.
Using these features can be a quick way to locate or review sets of media files in your project.
For example, looking at the Demo Project, if you wanted to find the set of files from families with full-time working fathers who showed increases in the quality of reading by the home's primary caretaker, you would follow these steps: 1. Click the Uncheck All button in the Columns panel. (Note that only 20 columns can be viewed at a time.) 2. Open the Field folder in the columns panel 3. Click the check boxes for “PC reading change group” and “Father work status” and you'll see the folders for these fields appear in the Filtering panel 4. Open these folders in the Filtering panel and click the “Positive Change” and “Full Time” check boxes to filter your media files to just this subset.
Filters can be cleared by clicking the Clear Filters button at the bottom of the panel.
We call this tool our SuperMegaGrid and you'll see these filtering features in some other Dedoose Workspaces and in the Data Selector.
How to Edit a Document
Example of the document Search function
The Document Viewer allows you to browse the text, create and code excerpts, search for text or character location, and manage all aspects of the document.
There are a variety of controls for how you can view and work with your document:
Information on document creation date, creator, and number of excerpts is noted in document header along with buttons to create and link memos to the document and create and/or link descriptors.
Renaming, Deleting, Editing, Cloning, and Describing Documents
A document's title will be displayed in the upper left corner of the viewer panel. The 'edit' document button (cog icon) can be found in the upper right side of the viewing panel. Clicking this button presents a pop-up to allow for document property controls, including:
The magnifying glass icon in the upper right corner of the document panel provides access to your search tools. To search for a keyword or text string, enter the text and click 'Submit' Dedoose highlight all words with that string and allows you to move among the 'hits' using the 'Back' and 'Next' buttons. These following screenshot shows the search tool icon and pop-up. In this example we searched for 'reading' and the results show that there were 21 matches and each match highlighted in pink so you can easily move through your document to locate this text in context and conduct any appropriate excerpting, coding, and memoing. The search tool pop-up is a movable panel (just drag and drop the panel header), and also allows for searching by character position and line number.
Note: Currently, text searching can only take place WITHIN a single document. Functionality for cross-document searching will be added in the near future.
Audio and Video File Viewing and Listening
The audio and video viewer allows you to watch and/or listen to your media, create and code excerpts, create transcripts, and manage all aspects of the file.
Screenshot of the Video Viewer
The audio viewer looks the same as the video viewer above except a sound wave will be shown in the primary viewing area. There are a variety of controls for how you can view and work with both your audio and video files.
The viewing panel will also have the name of the video along with a button to create and link excerpts, memos, and descriptors. You can also view the number of memos and descriptors that are currently linked to the file (shown in the screenshot above).
Renaming, Deleting, and Describing Audio and Video Files
When viewing an audio or video file, the name of the file appears in the upper left corner of the viewing panel and the edit button (cog icon) will be found in the upper right. Clicking this button presents a pop-up where you can control the media properties, including:
Importing Transcripts of Audio Stream
To import a transcript into Dedoose:
Adding Transcripts Manually
To add a transcript manually into Dedoose:
Audio stream transcripts in Dedoose live within an active editor. To edit a transcript in Dedoose:
Synchronizing Video/Audio Excerpts to a Transcription
To synchronize video/audio excerpts to transcribed text:
Finally, note that the transcript editor is always active for modification. The 'End' marker will automatically adjust as any editing within the boundaries of an already synchronized portion of text takes place.
Upon creating or importing a media file to Dedoose, note that it is not yet linked to any descriptors. This is indicated through the red-colored 'Descriptor: 0' button in the upper-right corner of the media viewer.
To create the relationship between the media file and associated descriptor data, click this red Descriptor button to open the linking pop-up. Clicking the 'Link' button for the appropriate descriptor establishes this relationship. In the example below, the document has been linked to the descriptor with ID = '7.05' As an alternative, you can also click the 'Create and Link Descriptor' button in the lower right corner of the pop-up if the data for the particular case has not yet been added to the descriptor set.
