Text Visualization Tools

Antconc: Is free­ware that is cross plat­form for Mac, Win­dows, and Linux. It is a con­cor­dance pro­gram that gives you the abil­ity to see text con­cor­dances, col­lo­cates, a word list (with an abil­ity for a stop list), and a key­word list. You can export a word list with a word fre­quency count to import into other visu­al­iza­tion tools. http://www.antlab.sci.waseda.ac.jp/software.html

Voy­ant Tools: Voy­ant Tools is a free web based suite of tools that allows for you to copy and paste text into a textbox, upload a file, or use an already pre­de­ter­mined cor­pus and use dif­fer­ent tools to visu­al­ize your text. The suite includes Cir­rus, a Sum­mary that totals all the words, includ­ing the num­ber of the unique words and a list of the most fre­quent words, a Cor­pus Reader that lets you see all your text and select cer­tain words and high­lights them, Word Trends win­dow that shows you the fre­quency of a cer­tain word or words through­out the text in a link graph for­mat, and Key­words in Con­text, which just like Antconc, pulls out where the word occurs in a sen­tence so you can see how it’s being used. The Cir­rus win­dow pro­vides a word cloud rep­re­sen­ta­tion of the word fre­quen­cies in the text. You can save the word cloud as a PDF. You can also export as an html page with all the data, an html snip­pet, or a bib­li­o­graphic cita­tion for Voy­ant. You also have the abil­ity to apply an already for­mat­ted stop list to pre­vent com­mon words from show­ing up in your data visu­al­iza­tion or even cre­ate your own cus­tom stop list. Other tools on the Voy­ant site are Word links (cre­ates a mind map of words) and a scat­ter plot (for word fre­quen­cies).  http://voyant-tools.org/

Wor­dle: Wor­dle is a free web based word fre­quency word cloud gen­er­a­tor. You can copy and paste text into a textbox to get started or pull in data from a url, or an RSS or ATOM feed. It will dis­play words that are men­tioned a lot in large font and oth­ers that are as often in a smaller font. You can change the font, lay­out, and color scheme and even exclude words in other lan­guages. You can print the text visu­al­iza­tion to a printer or open in a new win­dows or save it into a pub­lic gallery that oth­ers can see. http://www.wordle.net/

TagCrowd: TagCrowd is a free (for non-commercial use) web based word fre­quency word cloud gen­er­a­tor (sim­i­lar to Wor­dle). TagCrowd allows for you to add text by copy­ing and past­ing text into a textbox, a web­page url, or upload a file. You can choose the lan­guage, max num­bers of words to show in the word cloud, min­i­mum fre­quency of words, dis­play the fre­quency num­ber next to the word, group sim­i­lar words (Eng­lish only), and type in words for a stop list. Once you run the text through and cre­ate a word cloud, the words that are most fre­quent will be larger and the words that are not men­tioned as much will be smaller. You can save the word cloud as embed­ded html, a PDF, or you can send it to the printer. http://tagcrowd.com/

Chartle.net: Chartle.net is a free web based chart cre­at­ing site where you can enter data (like word fre­que­cies) and dis­play them as a chart. You can choose from dif­fer­ent styles of charts such as a pie chart, line or bar graph, scat­ter plot, Venn dia­gram, radar chart, etc. With each chart, you can cus­tomize the title, the scale (width), where the leg­end appears and the color of each piece of data that will be dis­played on the chart. Once your chart is built, you can pub­lish it on the Chartle.net site. When you pub­lish it on the site, you can then use the html embed code pro­vided by Chartle.net to embed the chart into a web­site. http://www.chartle.net/

Edin­burgh GeoP­arser: The Edin­burgh Geo­Praser allows you to upload a file of text and the geo­praser finds the loca­tions of places in your text. It will find the place on a Google Map and also give you alter­na­tive places with the same name. You can click on the coor­di­nates and that will jump you from loca­tion to loca­tion on the Google Map. This is a great visu­al­iza­tion tool to see where some­one or some­thing is trav­el­ing or places that are affected in the text.  http://www.ltg.ed.ac.uk/clusters/Edinburgh_Geoparser/ Demo: http://scargill.inf.ed.ac.uk/geoparser.html

Gephi: Gephi is an open source visu­al­iza­tion and manip­u­la­tion tool that you down­load onto your desk­top. It is avail­able for  Mac, Win­dows, or Linux. Gephi is a tool that you can really use to ana­lyze your data and net­works and rela­tion­ships with that data. The tool can be com­pli­cated at first, but once you get the hang of how to import your data and manip­u­late it visu­ally using Gephi, it is a pow­er­ful tool in your toolkit. Gephi dis­plays data in a mindmap­ping design where col­ors can be applied, labels can be applied to the data nodes dis­played. Lay­out algo­rithms give the shape to the graph which you have the abil­ity to change on the fly (since Gephi pro­vides real time visu­al­iza­tion). Dif­fer­ent fil­ters can be placed on the data which in turn changes the visu­al­iza­tion results of the Gephi out­put file and those queries can be saved in case you want to run the same fil­ters on the data later. Gephi will help you see pat­terns and under­ly­ing asso­ci­a­tions with text, clus­ters, and net­works. It is rec­om­mended that a new user runs through the starter guild and a few tuto­ri­als before import­ing data. A con­ve­nient fea­ture of Gephi is that it allows for you to import your data as a .csv file. There are also plug-ins that the Gephi user com­mu­nity has devel­oped that you can add to your Gephi soft­ware to extend it func­tions and fea­tures. https://gephi.org/
