Re: AntConc使用基本步骤
好的。以下是前面翻译的原文。
**Concordance**
The **Concordance** tool generates concordance lines (or KWIC: key word in context) lines from one or more target texts chosen by the user.
To produce a set of concordance lines of text, a user needs to perform the following actions:
1) Select one or more files for processing from using the 'Open File(s)...' or 'Open Dir...' options in the 'File' menu. The list of selected files is shown in the left frame of the main window.
2) Enter a search term on which to build concordance lines in the entry box on the left of the button bar.
3) Choose the number of text characters to be outputted on either side of the search term, using the increase and decrease buttons on the right of the button bar under the "Search Window Size" title. (default value is 50 characters)
4) Click on the 'Start' button to start the concordance lines results generation. The concordance generation can be halted at any time by clicking on the 'Stop' button.
5) Select a target word on which to rearrange the concordance lines, using the buttons to the right of the button bar. 0 is the search word, 1L, 2L... are words to the left of the target word, 1R, 2R .. are words to the right of the target word. Note that three levels of sort are possible, with the second and third levels not-activated when the software is first launched.
6) Click on the 'Sort' button to start the sorting process.
7) Move the cursor over the highlighted search term in one of the concordance lines. The cursor will change to a small hand icon. Clicking on the highlighted search term, will allow the user to view the search term hit as it appears in the original file via. the **File View** tool (see below).
Note that the total number of concordance lines generated (hits) is shown in the middle of the AntConc button window. This number will flash with the word "FINISHED" when processing has been completed, and will flash with the word "NO HITS", if not hits are generated for a particular search term. In this case, the concordance lines view will not be updated, and the previous set of concordance lines will remain visible.
Search terms can be specified as being "words"(default) or "word fragments" by choosing the "Word" search term option. Also, searches can be either case sensitive, or case insensitive (default) by choosing the "Case" search term option. Searches can also be made using full regular expressions by choosing the "Regex" option. For details on how to use regular expressions, consult one of the many texts on the subject. E.g., Mastering Regular Expressions (O'Reilly & Associates Press) or type "regular expressions" in a web search engine to find many sites on the subject.
Information about regular expressions can be found at:
http://www.regular-expressions.info/quickstart.html
By clicking on the "Advanced Search" button, more complex searches become possible. The first advanced search option is to define a set of search terms, either by typing them one per line, or by loading in a list of search terms from a file. Note that each line will be treated as a separate search term. The feature allows the user to use a large set of search terms without having to re-type them each time. The second advanced search option is to define context words and a context window within which the search term(s) must appear. For example, to search for "student" where it appears at least three words to the left or right of the word "university," set the search term as "student," the context word as "university," and the context window as 'From' 3L 'To' 3R.
A number of menu preferences are available with this tool. (See below).
**Concordance Plot**
Generating concordance plots can be achieved using the same actions as when using the **Concordance** tool. However, the **Concordance Plot** tool offers an alternative view of concordance lines. Here, all the hits for each file are plotted in the form of a 'barcode' indicating the position in the file where the hit occurred. The plot provides an easy way to see which files include the target search term, and can also be used to identify where the search term hits cluster together. An example of the use of the plot is in determining where specific content words appear in a technical paper, or when a character appears during the course of a novel or play.
The number of hits and length of each text is shown to the right of the barcode plot, and the plot itself can be enlarged or reduced in size using the zoom buttons
If you move the cursor over the highlighted search term in one of the concordance lines. The cursor will change to a small hand icon. Clicking on the highlighted search term, will allow the user to view the search term hit as it appears in the original file via. the **File View** tool (see below).
**File View**
At any time a target file can be viewed in its original form using the **File View** tool.
To produce a view of the original file, a user needs to perform the following actions:
1) Select a file to view in the file list frame to the left of the main window.
2) If a search term has been specified, the search term hits will be highlighted throughout the text. Search options are the same as for the **Concordance** and **Concordance Plot** tools.
3) Use the "Hit Location" buttons to jump to the appropriate hit in the file.
4) Change the search term and click on the 'Start' button to view other hits in the file.
5) Clicking on the highlighted text will generate a set of KWIC lines using the highlighted text as the search term.
Below is a list of Shortcuts unique to the **File View** tool.
CTRL-Click = Jumps to the nearest hit in the window
**Clusters**
The **Clusters** tool is used to generate an ordered list of clusters that appear around a search term in the target files listed in the left frame of the main window.
The clusters can be ordered either by frequency or the start or end of the word. They can also be ordered by the probability of the first word in the cluster preceding the remaining words. All list orderings can also be inverted. Also, a user can select the minimum and maximum length (number of words) in each cluster, and the minimum frequency of clusters displayed. It is also possible to select if the search term always appears on the left or right of the cluster. (Note: In the current version, if more than one word is specified as the search term, only the first word will appear on the right, if the "Search Term on Right" option is selected.)
To produce a cluster list , a user needs to perform the following actions:
1) Choose the appropriate ordering options.
2) Press the 'Start' button. At any time, the generation of the clusters list can be halted using the 'Stop' button.
3) Clicking on the cluster will generate a set of KWIC lines using the text as the search term.
