The output option Summary in the Query search is the first of three main functions of automatic content analysis in AmCAT. The Summary function is very useful to get a first impression of the content of the debate concerning your topics of interest in the documents. It lists all articles from the selected article set(s) that contain one or more of the search terms you entered in the 'Keyword search' field, as well as an overview of the textual context of the search keywords in each article, and aggregations per time period and per media outlet.
The example shown in the screenshots on this page illustrates this. When you select the output option 'Summary' and click on the 'Query' button below the output options, AmCAT provides you with the number of articles in which one or multiple of your search terms occur, followed by a list of these documents under 'Found # articles'. Of each article, a number of characteristics is displayed: the headline of the article, the date, the number of words, the medium (media outlet) and the context in which your search terms were mentioned in the text (with your search terms highlighted in yellow). In this example, the search term "nuclear acciden*" is used. As you can see, a total of 659 articles was found that used the terms ‘nuclear accident’ or ‘nuclear accidents’. The first article in the list was published on May 1st, 1985 and mentions either of these terms at least three times (since the words are highlighted in yellow three times in the article preview). When you click the headline of an article in this list, AmCAT opens the full text article in a new tab, with the search terms highlighted in yellow, and some additional article details.
To the right of the list of articles, a line graph shows the amount of articles that contain the search terms, shown over time. AmCAT automatically picks a suitable time interval for the x-axis. Hovering the cursor over this line graph brings up a text bubble that shows the exact amount of articles for that time period. If you click on the text bubble, AmCAT shows a table that lists the articles for that time period included in the articleset. In the example to the right, the table shows a list of articles for the first quarter of 1982, which showed a peak in the line graph for the amount of articles about nuclear accidents. The headlines shown in the table may give insight into why this peak occurred (i.e. what happened in this particular time period). Clicking on the three lines symbol to the upper right of the graph allows you to download the graph as PNG or JPEG image, PDF file or SVG vector image.
Below the line graph, a bar chart shows the search results aggregated for the different media outlets. For the article set used here, all articles were published in the New York Time, hence the chart shows only one bar. As with the line graph with time series, hovering the cursor over the bar chart pops up a text bubble that shows the amount of articles per media outlet, which you can click to display a table listing those articles. The bar chart, too can be downloaded as PNG, JPEG, PDF or SVG.
