Don’t forget that this post is part of a series of tutorials:<\/p>\n

    Concordance basics<\/i><\/strong><\/p>\n

    1. Open your file(s). In that example, we are going to use a simple example of only two texts: the english webpages about the countries United States and United Kingdom. You can find them at our <\/span>datasets folder<\/span><\/a>.<\/span><\/p>\n

    \"\"<\/p>\n

     <\/p>\n

    2.\u00a0<\/span>Generate a Word List<\/a>.<\/p>\n

    \"\"<\/p>\n

     <\/p>\n

    3. Click on the Concordance tab. Now you can search for a letter, word or expression. We searched for the term \u2018war\u2019 and, as you can see, we got a total of 107 Concordance Hits. This is the sum of the total amount of results to that specific search in the two files.<\/span><\/p>\n

    \"\"<\/a><\/p>\n

     <\/p>\n

    4. By default, the search term will be highlighted in blue and up to three terms on the right will be highlighted in red, green and purple. You can change those colors in <\/span>Global Settings<\/span><\/i>.<\/span><\/p>\n

    They are useful to understand and sort the words in the vicinity of our term (or terms) of interest.<\/span><\/p>\n

    \"\"<\/a><\/p>\n

     <\/p>\n

    5. At the bottom, you can change the Kwic (Keyword-in-context) settings and choose which items you want to highlight and sort in the Concordance tab. You can select up to three levels. In the following images, 1R stands for \u201c1 Right, or first item on the right\u201d, 1L stands for \u201c1 Left, or first item on the left\u201d and so on.<\/span><\/p>\n

    \"\"<\/p>\n

    \"\"<\/p>\n

     <\/p>\n

    Changing the levels to 1L, 2L and 3L will result on something like the following:<\/span><\/p>\n

    \"\"<\/p>\n

     <\/p>\n

    World War<\/span><\/i><\/p>\n

    \"\"<\/a><\/p>\n

     <\/p>\n

    as * as<\/span><\/i><\/p>\n

    \"\"<\/a><\/p>\n

     <\/p>\n

    Concordance plot<\/i><\/strong><\/p>\n

    The concordance plot is a straightforward way to compare two or more corpora, their concordance hits and the distribution of words or phrases along them.<\/span><\/p>\n


    \n1. It is very simple to use the Concordance Plot. Just generate a Word List (if you haven\u2019t already), search for a word or phrase on the <\/span>Concordance<\/span><\/i> tab and click on the <\/span>Concordance Plot<\/span><\/i> tab. Let\u2019s use that same example from before, searching for \u2018war\u2019:<\/span><\/strong><\/p>\n

    \"\"<\/a><\/p>\n

     <\/p>\n

    2. As we can see, the word \u2018war\u2019 is much more common on the United States WIkipedia page. What does that mean? It could be a indication of more interest on war between the editors of the USA wikipedia page, for example?<\/span><\/p>\n

    \"\"<\/a><\/p>\n

     <\/p>\n

    3. You can increase the zoom on the visualization in the option <\/span>Plot Zoom<\/span><\/i>:<\/span><\/p>\n

    \"\"<\/a><\/p>\n

     <\/p>\n

    4. You can observe in Step 2 that besides the number the fact that the characters in each file are different (126k x 135k), the rectangle representing the files has the same width. This is because the visualization is <\/span>normalized<\/span><\/i> to facilitate some comparisons. You can change that going in <\/span>Tool Preferences<\/span><\/i> -> <\/span>Concordance Plot<\/span><\/i> and selecting the option <\/span>\u201cUse a relative lenght<\/span><\/i>\u201d in the <\/span>Plot Length Options<\/span><\/i>.<\/span><\/p>\n

    Now you can see a width that better represents the length and the difference between the files:<\/span><\/p>\n

    \"\"<\/a><\/p>\n

     <\/p>\n

    Searching for a list of words<\/i><\/strong><\/p>\n

    1. At the <\/span>Concordance <\/span><\/i>tool, as well in other AntConc tools, we can search for a list of words at once. Those words could be inserted manually or through a txt file.<\/span><\/p>\n

    \"\"<\/p>\n

     <\/p>\n

    2. In the Advanced Search options you can check the option \u201c<\/span>Use search term(s) from list below<\/span><\/i>\u201d and input the words. In the following example, we used the expressions below to include also terms like \u201ceconomics\u201d, \u201ceconomically\u201d, \u201cfinance\u201d, \u00a0\u201cfinancial\u201d etc.<\/span><\/p>\n

    \"\"<\/p>\n

     <\/p>\n

    3. Alternatively, you can click on \u201c<\/span>Load File<\/span><\/i>\u201d and upload words from a .txt file.<\/span><\/p>\n

    \"\"<\/p>\n

     <\/p>\n

    4. With this technique you can look and explore concordances for words with semantic similarity:<\/span><\/p>\n

    \"\"<\/a><\/p>\n

     <\/p>\n

    5. Finally, another option on the <\/span>Advanced Search<\/span><\/i> specifications is to use Context Words and Horizons. The terms searched are filtered out according to proximity to other words. In the example below, the combination of terms related to war and conflicts to a filter of instances next to \u2018crisis\u2019 and \u2018depression\u2019 could be used for understanding the relations between war and economic problems:<\/span><\/p>\n
