IBM Word-Cloud Generator
What it does: Several tools mentioned previously can create word clouds, including Many Eyes and the Google Visualization API, as well as the website Wordle (which is a handy tool for making word clouds from websites instead of text files). But if you're looking for easy desktop software dedicated to the task, IBM's free Word-Cloud desktop application fits the bill.
What's cool: This is a quick, fun and easy way to find frequency of words in text.
Drawbacks: Because it's trying to ignore words such as "a" and "the," the basic configuration can miss some important terms. In my tests, it didn't know the difference between "it" and "IT," and completely missed "AT&T."
Skill level: Advanced beginner. This app runs on the command line, so users should have ability to find file paths and plug them into a sample command.
Runs on: Windows, Mac OS X and Linux running Java.
Social and other network analysis
These tools use a pre-Facebook/Twitter definition of "social network analysis" (SNA), referring to the discipline of finding connections between people based on various data sets. Investigative journalists have used such tools to, for example, find links between people who are involved in development projects or who are members of various boards of directors.
An understanding of statistical theories of network node analysis is necessary in order to use this category of software. Since I've only had a very basic introduction to that discipline, this is one category of tools I did not test hands-on. But if you're seeking software to do such analysis, one of these might meet your needs.
