Gibson Testimony Intelligence

Welcome to Gibson!

We are thrilled to have you join our growing family of Gibson users. Gibson uses Power BI as its front end, so if you are familiar with Power BI, you already know how to use Gibson. The same familiar features, like viewing the data as a table or exporting to Excel, are available to you in Gibson. 


If you've never used Power BI, we're excited to show you just how easy and intuitive Gibson is. And don't worry, you can't break it! If you ever get yourself down a rabbit hole of data and you're not sure how to get back to the beginning, simply press the Reset button in the upper right.

Keyword Search vs. Topic Search

Gibson User Guide 


Keyword Search versus Topic Search


A common question we receive is, “How do I conduct a keyword search of the content?”


Gibson does more than just search keywords. Gibson searches topics, which may include several related keywords. If you need to search within the topics, you can do it on the Testimony by Topic page. 

Why should you trust the topics produced by an AI?

Over decades, most computer and web users have been conditioned to use keyword search as their primary tool. However, this method is limited by the memory of the user and it is time-consuming. You can’t search for topics that you don’t know exist. We’ll refer to this technique as “pulling” data from an archive of transcripts.

(A similarly limited method would be to look at the index at the end of a typical deposition transcript. In rare instances, an attorney might glean some intelligence or find a quote within a given transcript, but they may take several minutes to actually find the corresponding quote.)


Current AI technology uses natural language processing to analyze enormous volumes of text. Gibson’s AI goes beyond keywords to look for related concepts. For example, an ordinary user might want to look for argument or testimony that references dogs. They may search for a specific breed of dog. But the Gibson AI will also detect and index concepts such as “canine,” “wolf,” "mutt," and “hound.” Gibson is “pushing” data to the user that they might otherwise overlook, and the user sees this data instantly.


Not only are you seeing relevant, related concepts that you might not know existed, but you may also see those concepts discussed across multiple transcripts, by multiple attorneys and witnesses, and even across multiple matters. This radically accelerates comparisons among all fact, expert, and corporate witnesses, as well as attorneys.


Gibson also allows you to tune the sensitivity of its topic filter so that you can see more “noise” topics – which may or may not be useful – that would otherwise not be shown to you. The upshot of having an AI doing the topic extraction for you is that you spend less time hunting for things that are not in the content, and more time exploring the topics that are present and relevant.

How to use Topic Timeline

Every visualization on this page allows you to "zoom in" to enlarge any visualization to a full page. Hover over the visualization until the option menu appears at top right. Look for the "Focus Mode" square.

  • The Topic Timeline contains page number references to every relevant topic as it was mentioned in each transcript. You can tell at what point in the deposition the attorney or witness mentions the given topic.

    • Grab the slider handles at the bottom of the visualization to shift your view of the page numbers. As you reduce the volume of references, they'll appear to spread out.

  • The X-axis page is the transcript page number. The Y-axis Topic Score represents Gibson's level of confidence in any given topic. Gibson defaults to a .3 topic score threshold (your instance may have a different setting). Points closer to the top indicate a high degree of confidence in a topic.

    • In a matter with more than a dozen transcripts, the Topic Timeline will initially look like a large mass of thousands of points, which is not useful.

  • The Witness Name drop down allows you to select one witness or, by holding down the Ctrl/Command button, select multiple witnesses. This will instantly update the Topic Timeline to reflect only the topics within those transcripts.

  • Topics by Volume of Content and Topics Word Cloud are two visualizations of the same thing. (Advanced users: both of these visualizations may change if you raise or lower the Topic Score threshold.)


The best way to use the Topic Timeline is to reduce the number of points by either limiting the number of selected Witnesses and/or by choosing a specific Topic from the list or the Word Cloud.

Do you have a general idea of when a particular topic was referenced in a given examination? Select your witness, then choose a range of pages in the Topic Timeline: click and drag to select a bunch of reference points. The other visualizations will update with your selections. You'll see a much smaller set of topics.


When you have achieved the Topics by Volume or Topics Word Cloud that you want, we recommend you use Focus Mode to "zoom in" to the Word Cloud and take a snapshot of the data.

How to use Topics by Witness

As with the Topic Timeline, you can zoom in to both visualizations. Hover over the visualization until the option menu appears at top right. Look for the "Focus Mode" square. 

To see topics discussed by any one witness, click on the witness name. The topic list will adjust to show you only topics found in testimony by that witness. You can also expand the witness name to show a Transcript File. This is particularly helpful when you have a witness who has testified multiple times. With the transcript file option expanded, you can now click the particular transcript you want and see all the topics discussed in that transcript.

The list of Topics shows a full list of all topics contained when no witness or transcript is selected on the left. Click on the + sign next to each topic to see all testimony on that particular topic. Click on the + sign again next to particular testimony to show the page and line number citation.


The best way to use the Topics by Witness tab is to work from Topic Name to the Witness and Transcript File if applicable, then search through those topic instances or export the result. For example, you know there's a relevant topic but you're not sure which transcript it appears in or you're not sure which witness or attorney said it. Use the Topics by Witness page to scroll to the relevant topic and expand it. Or right-click on the topic and select Drill Through. Gibson will automatically serve you the complete list of topic references on a new page.

How to Use Testimony by Topic

How to use Testimony by Topic

Testimony by Topic lets you use multiple lists to quickly filter data to find relevant quotes. As with the other pages, you can zoom in to specific visualizations. Hover over the visualization until the option menu appears at top right. Look for the "Focus Mode" square.

In the Topic list, you can select one topic or use Ctrl/Command to select multiples. You'll notice that as you select topics, the other visualizations automatically refresh to show you the respective witness and deposition file. If you search on a particular word or phrase, you can narrow down the list of topics to only those containing that word or phrase.


When you hover over a Transcript File or Filename, you can click to open the respective transcript. 


The best way to use Testimony by Topic is to filter for your desired topics and/or witnesses, then hover over the main content window to see the option menu. Either choose Focus Mode or the ellipsis to see "Export data." Export data will generate a downloadable file in one of multiple formats. We recommend selecting summarized data, .xlsx format without the live connection.

This is the most powerful Gibson tab because it allows you quickly search for topics important to your task, pull up relevant testimony, and even instantly call up relevant transcript if you need to see more context. The page also shows you the citations for each piece of testimony so you can find it in the transcript. 

How to Use Cases by Witness

How to use Cases by Witness

For multi-matter projects, the Cases by Witness tab helps you rapidly organize large lists of witnesses with a customizable taxonomy.

Default tags include Witness Alignment and Witness Type, Expert Type. The default categories within these tags are drawn from the SALI standard. You can add additional categories by asking your Cloud Court project manager.


The best way to use Cases by Witness is to isolate a class of witness to compare testimony across multiple witnesses, or compare a witness' testimony in multiple cases.


For example, your opponent has repeatedly hired several experts to testify in multiple cases and you want to compare their testimony for contrast and consistency. Cases by Witness will help you ensure you're not missing a relevant witness from the comparison.


TIP: Gibson will "save" your filters as you switch from page to page. You can go to the Topics by Witness tab to select your resulting list of witnesses and return to your Cases list to double-check.
