Wordcorr tools

Module by: Joseph Grimes. E-mail the author

Summary: Wordcorr provides tools to enter and edit data, define differing analytical views of the data, annotate comparable data, tabulate correspondence sets, and review and refine the results of the analysis.

Here are some of the main things Wordcorr helps you with. There are other tools that will come up later, but these are the key functions.

Enter Data. Type in word lists for comparative analysis. The first word list establishes the sequence of entries for all the others. You have access to the complete International Phonetic Alphabet plus some other symbols. You can edit data after typing them in.

Define View. Since alternate analyses of the same data are possible, you perform each analysis in a separate view. You give each view a name, decide which speech varieties of the collection are to appear in the view and in what order, and the threshold percentage of the varieties in the view that must contain a datum in order to form a correspondence set.

Annotate. For each entry, you examine the data and decide which words could plausibly have descended from the same ancestral form (usually called the protoform, which you will endeavor to reconstruct). Each set of such words constitutes a group, and each group gets a one-letter tag. Within each group, you line up the segments that match each other, perhaps stretching the shape of some words by typing in the Indel symbol "/" to indicate that either a new sound may have been inserted in some of the words that would otherwise match, or a sound may have dropped out at the point where you insert the symbol. There are some minor tools for annotation as well. All the words in a group must have the same number of symbols; but different groups in the same entry do not have to have the same number of symbols.

Tabulate. Once all the groups in an entry are annotated, the groups with enough speech varieties entered to meet or exceed the view's threshold are taken up one at a time. Wordcorr transforms each group into correspondence sets. For each correspondence set, you indicate the probable protosegment of the protolanguage that the set represents, and indicate the phonological environment in which it probably was situated within the protoform. At first these judgments are only educated guesses; but as you proceed, patterns you begin to recognize take shape to give an attested picture of how changes happened.

Refine. As soon as a group is tabulated, its correspondence sets appear in the view's Results structure, which is organized phonetically, by the place and manner of articulation of the protosegments. You can refine it there, moving things around, changing protosegments, environments, and orderings. You can also extract a summary of the evidence for your hypotheses about language change, print out the whole results structure, or extract just the raw data.

Problem 1

The outcomes of annotation and tabulation are kept for you in permanent form.

Lenses

A lens is a custom view of the content in the repository. You can think of it as a fancy kind of list that will let you see content through the eyes of organizations and people you trust.

What is in a lens?

Lens makers point to materials (modules and collections), creating a guide that includes their own comments and descriptive tags about the content.

Who can create a lens?

Any individual member, a community, or a respected organization.

What are tags? tag icon

Tags are descriptors added by lens makers to help label content, attaching a vocabulary that is meaningful in the context of the lens.
