July 2019: New design for the analysis report #
Urkund is releasing a new and more user-friendly view of the analysis report in July 2019. The information in this article is about the old view. The article will be updated after the summer vacation is over.
In the meantime, you can read Urkunds user guide to the new analysis report.
Understanding the Urkund analysis report (old) #
Contents of the report #
Urkund compares a submitted answer with previously submitted answers at NTNU and texts available via sources on the internet. The system carries out an analysis and creates a report that indicates the degree of similarity in percent between the answer and other texts. We have called the number "hit percentage". In order to assess whether it is a matter of plagiarism or not, one has to look closer at the cases where there are similarities.
The analysis report also provides references to sources sorted according to where text with similarity occurs from the beginning of the submitted document. Inclusion of the individual sources can be turned on and off. The total hit percentage will change accordingly. The sources can be sorted and source documents can be viewed if there are no restrictions.
How to find the report from the analysis #
The report is available from the system in which you initiated the plagiarism check. You can pick it up by clicking on the field where the hit percentage is specified. Details are described in the instructions for these systems. This video shows a review of the analysis report.
Overview of the analysis report #
The report interface looks like: Each of the 3 sections provides information about:
- Section 1 contains information about what is sent when, from, to whom, and the total hit percentage of similarity with different sources. You can download the document that has been submitted. If the sender has written a message, the subject field appears in the message as well as link to the message.
- Section 2 shows which sources have been reviewed in the analysis. Primary sources are indicated by blue rank (bold horizontal blue line) while alternative sources covered by the primary sources, as well as unused sources are indicated by grey rankings.
- Section 3 is divided into 3a and 3b.
- Section 3a shows text from the submitted document found in one or more of the source documents listed in section 2. Note: Only text is displayed. Images, tables, and other media or graphic elements have been removed.
- Section 3b is the source view. The view shows text that, to a greater or lesser extent, has similarities to the text in the submitted document. Unless there are restrictions on displaying text in the source, the entire text in the source can be retrieved (downloaded) from the source in section 2.
- Between the sections, there is a toolbar with a set of features that can be used to highlight and show details in the report.
- Below is a more detailed explanation of each section. It will be too detailed to explain all the elements. We recommend that you try out by clicking on the individual items and menus in the report. You will see what happens and probably soon understand the logic and how things are connected.
A detailed explanation of each section #
Section 1 - Submission Details #
The numbers in the image refer to the list below.
- Link to the submitted document. You can download the document or open it in your text editor.
- Date when the document was submitted.
- The sender of the document. If you submit/upload the document yourself, your email address will appear here.
- To whom the document has been sent. The recipient's account in Urkund (the analysis account).
- Message from the person who submitted the document. The text that is written in the subject field in the e-mail or in the subject field when uploading a document is shown. If a code is specified in "" for sorting to a folder, it will appear. The entire message can be retrieved by clicking on the link.
- Hit percentage for the degree of similarity. If you disable/enable a source, the percentage will change so you can see what effect the source has on the total hit percentage. Note: Changes in hit percentages due to disabling/enabling of sources only appear in the report view and not in Blackboard or Inspera Assessment.
Section 2 - Sources #
Section 2 has the tabs: (1): Sources and (2): Highlights.
"Sources" tab #
- Sources are rated and listed from the top the source where the most similarity is found. (Longest blue horizontal line).
- You can open a source by clicking the plus sign, "+". The sources and hit percentages are shown.
- By clicking on a hit percentage, the corresponding text will appear in the submitted document and source in section 3a and 3b, respectively.
- By clicking on the link of the source, the source can be retrieved (provided there are no restrictions on displaying contents of the source).
- A source can be disabled/enabled by ticking in the box to the right of the source. This is useful if you want some sources to be excluded from the comparison. When this is done, the hit percentage will be recalculated as shown in section 1.
- "Alternative sources" are sources that contain text that is part of the primary sources.
- "Unused sources" are sources that have been used during the analysis, but ultimately turned out to have no degree of similarity affecting the final result. Sources found, but which turned out not could be processed, are also included here.
"Highlights" tab #
- The sources are shown in descending order according to where text from the source appears from the beginning in the submitted document.
- Sources where the hit percentage is coloured are included in the analysis. Clicking on one of the coloured (or grey) fields will display the corresponding text in the submitted document and source document. The sign "> " that appears to the left of the hit percentage indicates which source you are viewing.
- Sources can be disabled/enabled by checking the box to the right of the path/filename.
The toolbar looks like:
- Button to turn on and off display of disabled hits in the text. The graphical markings (bars) show where in the text Urkund has found similarities with other sources.
- Shows/hides text differences in paragraphs/text that is compared. This feature is useful to see in detail what is different between the source document and the submitted document. Text marked with RED indicates text that has been removed or added. YELLOW indicates synonym or text that has been moved.
- View text in quotation marks, " ", in the submission.
- Highlight text in brackets.
- Go to the first text/paragraph in a submission where the analysis has found similarities. The source is also indicated by ">" in section 2.
- Go to previous text with similarity.
- Go to next text with similarity.
- Warnings! Areas/text which Urkund cannot recognise. Eg. insertion of unknown characters.
- Cancel changes that you have made during your review of the analysis. This means back to the original report.
- Export the analysis, including changes made, to a PDF file. A dialog box stating that export is in progress comes up.
- Share the analysis with others. A unique link that you can share with others is generated. Note that anyone who receives the link can retrieve the analysis. There is no requirement that they are logged on to Innsida or have an NTNU account.
- Help - link til user guide on handling duplicates and a screen-cast on understanding the analysis report.
Section 3 - Analysis #
- On the left side (Section 3a) you find the submitted text.
- On the right side (Section 3b) you find the text from the source being viewed.
- When you click button 1, disabled, alternative hits are shown.
- A set of vertical posts appears. The posts indicate areas of text that have a degree of similarity with text in one or more sources. Text areas and posts that are coloured (enabled) are included in the total hit percentage indicating similarity. Posts that are grey also indicate paragraphs/texts with similarity, but the texts are not included in the total hit percentage from the analysis.
- You can enable text that initially is not included in the hit percentage by ticking the box to the right of "Active" in section 3a. The text will be included in the analysis and the total hit percentage. Display of text changes from grey to a coloured background depending on the hit percentage.
- When you either click on;
- a horizontal blue line under the tab Sources
- or on the hit percentage of a source under the Highlights tab, in section 2
- or a vertical post in section 3a, the text of the submitted document is displayed together with the text in the source document in section 3b. This applies also if the source is included in the analysis or not. In this way you can navigate and review similarities between text in the submitted document and text in the source documents.
- You can display disabled hits and peculiarities in the text using the function buttons. Here we have ticked off buttons to display:
- (1) deactivated sources,
- (2) text differences,
- (3) text written in quotation marks and
- (4) text written in brackets.
- By removing the checkmark in the box to the right of "Active" in the image above, the text is disabled from the analysis. The total hit percentage in section 1 will change when you do this.
