The Similarity Report

The Similarity Report provides an overall similarity breakdown for each submission to the iThenticate database. This breakdown determines the percentage of similarity between a submission and content existing in the database of the text comparison tool, iThenticate.

Interpreting the Similarity Report

iThenticate does not check for plagiarism in a submission. It checks a submission against the content database, and if there are instances where the submission's content is similar to, or matches against, one or more sources, it will be flagged for review. The database includes billions of web pages (both current and archived content), a repository of work that has been submitted to Crossref Similarity Check and Turnitin in the past, and a collection of documents, which comprises of thousands of periodicals, journals, and publications.

 

It is perfectly natural for a submission to match against sources in the database. If the submission has used quotes and has referenced correctly, there will be instances where there will be a match. The similarity score simply makes the user aware of any problem areas in the submission; iThenticate should be used as part of a larger process, in order to determine if the match is or is not acceptable.

Accessing the Similarity Report Through iThenticate

If you are accessing the Crossref Similarity Check through iThenticate, to view a submitted document’s Similarity Report navigate to the folder that contains the submission. 

 

 

The submitted document will be shown in the Documents tab of the folder. To view the Similarity Report, select the similarity index icon for that document. This is the percentage that is shown in Report column.

 

 

 

This percentage is the Similarity Score. It is an accurate representation of the documents Similarity Report, offering an immediate indication of the documents performance but it always warrants further exploration. Once selected, the report will open in the document viewer.

The Document Viewer

Below is the document viewer screen. It will open in the viewing mode that you last had the document viewer open in.

 

 

The document viewer is separated into three sections.

 

Along the top of the screen, the document information bar shows important details about the submitted paper.

 

 

 

This includes the document title, the date the report was processed, the word count and the number of matching sources found in the selected databases.

 

The left panel is the document text. This is the text of the submitted document.

 

 

The document will always be shown in full, and depending on what report mode you are viewing the report in there will be instances of similarity highlighted in a color that corresponds to the matching source. These matching sources are listed in the right panel, the sources panel

 

 

 

The layout will depend on which report mode you are viewing the report.

Report Modes

The document viewer can be viewed in four different modes. These modes allow you to view and sort the information contained in the Similarity Report to best suit your needs. The four modes for viewing a Similarity Report are:

  • Match Overview: (show highest matches together): A list of all areas of the paper which have similarity to information in the selected search repositories. Matches are color coded and listed from highest to lowest percentage of matching word area to the submission. Only the top or best matches are shown, all underlying matches are visible in the Match Breakdown and All Sources modes.

  • All Sources: Allows a user to view matches between the paper and a specifically selected source in the content repositories. Contains a full list of all matches found rather than the best matches per area of similarity. This listing is exhaustive but will show all matches found, including any that are obscured in the Match Overview by virtue of being in the same or similar areas as other, better matches.

  • Match Breakdown: Displays matches that are obscured by a top source. Allows users to compare the match instance of an underlying source with the match instance for a top source.

  • Side By Side Comparison: An in depth view that shows a document’s match compared side by side with the original source content from the content repositories. 

View Mode Icons

The view mode icons allow users to switch between the Similarity Report viewing modes: Match Overview and All Sources view. The default viewing mode is the Match Overview (the view mode icon on the left).

 

 

To change the view mode for a Similarity Report to the All Sources view, click on theAll Sources icon (the view mode icon on the right). The sidebar will automatically update to the All Sources view mode.

 

 

Match Breakdown Mode

In some cases, matches to smaller instances of similarity may be obscured by larger matches and not shown in this view mode. To find the underlying sources, hover over the match you would like to view the underlying sources for and select the arrow icon that appears.


 

In this mode, all sources that are obscured by the selected top source are listed below that source. Select a source to highlight the matching text on the paper text.


 

A source box will appear on the document, revealing where in the source the text has been identified. The highlight color for the top source match will become lighter and the matched text of the underlying source will be displayed with a darker highlight.

 

To return to the Match Overview mode click on the back arrow next to Match Breakdown at the top of the sidebar.

Side by Side Comparison  

Side by side comparison allows you to compare matching text within a document to the source of the match in the content repositories. In All Sources when you select a source from the sources panel, a source box will appear on the document text showing the similar content highlighted within a snippet of the text from the repository source. In Match Overview, select the colored number at the start of the highlighted text to open this source box. The source box provides the matching text within the context of a few outlying sentences from the repository source.

 

 

To view the entire repository source, select the Full Source View link. This opens the repository source in the sources panel and contains the full text of the source and all the matching instances.

 

 

The source’s full text will be displayed in the sidebar with each matching instance to the document highlighted in red. Click on the source title/URL to open up the original source in a web page.

 

 

 

If there are multiple matches to this source, select the arrow icons to quickly navigate through the match instances


Select the x icon in the top right corner of the full source text panel to close it.

 

Note: If a source is from a restricted or membership only repository (for example, Crossref), then you will be unable to view the full source text in a side by side comparison. You will still be able to see the source box snippet for context.

Viewing Live Web Pages for a Source

If a source is available on the internet users can open that source in a new browser.

 

To access a source website within Match Overview, select the colored number at the start of a piece of highlighted text on the paper text. A source box will appear on the document text showing the similar content highlighted within a snippet of the text from the repository source. The source website will be in blue above the source snippet. Select the link to open the site in a new browser.

 

 

From the Match Breakdown mode, if you select the source you want to view the website for, a diagonal icon will appear to the right of the source. Select this to open the source website in a new browser window.

 

 

The process is the same for All Sources mode. If you select the source you want to view the website for, a diagonal icon will appear to the right of the source. Select this to open the source website in a new browser window.

 

Note: Some internet sources may no longer be live. 

Filters and Exclusion

Excluding Sections  

To exclude a section, such as an abstract or a methods and materials section, below Exclude Sections select the check-box next to the sections you would like to exclude. iThenticate will exclude these by reading the document and excluding sections that have headers with the words 'abstract', 'method and materials', 'methods', 'method', 'materials', and 'materials and methods'.


 

Excluding a Match

If you determine that the match is not needed, you can exclude the source from the Similarity Report through the Match Breakdown or All Sources viewing modes. The similarity index will be recalculated and may change the current percentage of the Similarity Report.


To exclude matches for a top match in the Match Overview, hover over the match you would like to view the underlying sources for and click on the arrow icon that appears to enter Match Breakdown mode. In the Match Breakdown, select Exclude Sources to enter source exclusion mode.

 

 

Select the sources that you would like to remove by selecting the check-box next to each source. Once all the sources are selected select the Exclude (#) button to exclude the sources.

 

 

To exclude an entire source match from All Sources, select Exclude Sources to enter source exclusion mode.

 

 

Select the sources that you would like to remove by selecting the check-box next to each source. Once all the sources are selected select the Exclude (#) button to exclude the sources.

 

 

Exclusion List

The excluded sources list contains each source that was excluded from the Similarity Report. To access the excluded sources list click on the excluded sources icon at the bottom of the sidebar.

 

 

 

The excluded sources list shows all the sources you have selected to exclude from the report with a check-box next to each. Select the check-box next to the source you would like to re-include in the Similarity Report.

 

 

Select the Restore (#) button to include the source in the Similarity Report. To restore all of the sources that were excluded from the report select the Restore All button

 

If the re-included source or sources affect the similarity score percentage then the percentage will be recalculated.

Downloading a PDF Version of a Similarity Report

The Similarity Report can be downloaded in a print-friendly PDF


To download a report, select the print icon at the bottom left of the Document Viewer. This will prepare a readable PDF version of the report. When downloading a report, the downloaded version created is based on the current view of the Similarity Report. For example, selecting the download icon while using the default Match Overview will create a PDF with color-coded highlights.


 

Accessing the Text-Only Report

You can navigate to the text only report by clicking on the Text-Only Report button at the bottom right of the document viewer.

 


When you switch a Similarity Report to text only, it will remain in that view mode until you switch back to the Document Viewer mode; that is, if you close a report when it is in text only then it will still be in that mode when you reopen it.

The Text Only Report

The text only report allows you to view the Similarity Report without the document formatting. The view is separated into three main areas in the default view.

 

Along the top of the screen, the document information bar shows important details about the submitted document along with a menu bar with various options.

 

 

 

The information bar includes the document title, the date the report was processed, the word count, the folder the document was submitted from, the number of matching documents found in the selected databases and the similarity index. In the top right of the text only report there is a drop-down that allows you to switch between uploaded documents contained in the same folder.

 

The menu bar beneath the information bar has a mode selection drop-down menu, options to exclude quotes, bibliography, small sources, and small matches, as well as options to print and download.

Report Modes

The text only report can be viewed in four different modes. These modes allow you to view and sort the information contained in the Similarity Report to best suit your needs. You can select a mode using the drop-down menu on the left of the menu bar.


Similarity Report

The default viewing mode is the Similarity Report. This mode has a similar layout to the Document Viewer. The paper text is viewable on the left of the screen with the instances of similarity highlighted. The sources are listed on the right of the screen, color-coded and listed from highest to lowest percentage of matching word area within the submission.

 

 

Only the top or best matches are shown, all underlying matches are visible in the Content Tracking viewing mode.

 

Selecting the highlighted area of the text will display the full text of the source, with the similar content highlighted. To open this source in a new browser, select the show in web page link.

 

Content Tracking

Content Tracking mode lists all the matches between the databases and the submitted document. Since the database is updated regularly it may have many matches from the same source. These sources may be partially or completely hidden due to the content appearing in a higher matched source. The sources that are the same will specify where they were taken from and when.

 

 

Summary Report

The Summary Report mode offers a simple, printable list of the matches found followed by the paper with the matching areas highlighted. It shows the sources first, with the document text below.

 

 

Largest Matches

The Largest Matches mode shows the percentage of words that are a part of a matching text string (with some limited flexibility). In some cases, strings from the same source may overlap, in which case, the longer string in the largest match view will be displayed.

Changing Viewing Modes

By default the Similarity Report opens in the similarity report view mode which displays the highest matches within the matching sources. In some cases smaller areas of similarity may be obscured by larger matches and not shown with this view mode. To find the underlying sources, use the Content Tracking view mode to show an exhaustive list of the sources.

 

When a viewing mode has been changed by selecting it from the View: pull-down menu, the Similarity Report browser window will reload to display this view.

 

The Content Tracking view mode when selected, lists all sources, even those that are obscured by larger percentage matches in the default view. Select a source to display on the student paper to the left by clicking on the radio button next to a source. When printing, this view mode will print only the currently selected source.


 

Users may also view the Similarity Report showing only matching text and source links without the matching sources view. This is known as the Summary Report view mode. This view mode allows a user to view a source in its original format from the internet, or from the iThenticate database if the source is a journal or periodical, by clicking on the name of the source at the top of the Similarity Report. The Summary Report view mode is similar to the printed view of the Similarity Report.

 

The last mode is the Largest Matches viewing mode. This mode is very similar to the default mode but with one main difference, this viewing mode shows the percentage of words that are a part of a matching string of words, so the percentage for a matching source may change in this viewing mode.

Excluding or Including Content

The menu bar below the document information bar gives you the option to exclude or include content from the report.

Exclude or Include Phrases

When the exclude phrases setting is enabled for a folder, any submission made to that folder will exclude the phrases specified in the folder settings. If you would like to include these phrases in the Similarity Report, select the Do not Exclude Phrases link from the menu bar.

 

 

Once you have included the phrases in the Similarity Report, you will be able to exclude them again by selecting the Exclude Phrases link from the menu bar.


Excluding Quoted or Bibliographic Material

If quoted or bibliographic material is flagged as similar or matching, this information can be excluded from the Similarity Report. To exclude quotes and/ or bibliographic material from the report, select the relevant link in the menu bar.

 

 

When quoted or bibliographic material is excluded from a Similarity Report it may change the percentage of matching text found within the submission. Quoted or bibliographic material can be re-included by selecting the relevant links in the menu bar.

 

 

Excluding Small Sources and Matches

It is possible to exclude small sources and small text matches from within the text only viewer. To exclude a small source or a small text match from the report, select the relevant drop-down in the menu bar.

 

 

To exclude a small source enter a value into the word count or percentage field to set an exclusion threshold. Any source below the word court or match percentage threshold will be excluded from the Similarity Report. Select the Update button to set the exclusion setting.

 

 

To exclude a small match enter a value into the word count field to set an exclusion threshold. Any match below that threshold will be excluded from the Similarity Report. Select the Update button to set the exclusion setting.


 

Excluding a Match

Any source found in the database can be excluded from the Similarity Report in either the Similarity Report mode or Largest Matches viewing modes.

 

To the right of each source listed for a match will be a grey x icon. Select this icon to exclude the source. Any underlying source, if present, will replace the excluded source.


 

The similarity index will be recalculated and may change the current percentage of the similarity index if matches are excluded.

 

Once a source has been excluded, you can add it back into the Similarity Report through the content tracking viewing mode. The content tracking view mode lists all sources that have matching content with the submission. The excluded sources will appear with a plus icon to the right of their name within this view mode. Select the + icon to add this source back into the Similarity Report.


Return to the Document Viewer

To navigate back to the Document Viewer from the text only Similarity Report select the Document Viewer button in the top left.
