DESCRIPTION ^

Input file of links, link text and redirects in the data format described next. Use file name '-' to input stdin. Builds the tables used in bag processing: STEM.tokens N-th line is the token for items with index (N-1). STEM.words A map for the token file includes token, its type and the hash code. STEM.docs N-th line is the details for the N-th document STEM.docfeats mapping of token index to document index

The token to document index in .docfeats is implied after standardising OUTGOING-URLs for a document and the document URls themselves

DATA FORMAT ^

Input lines can have the R form for redirects: R <URL> <URL-REDIRECTED-TO>

These entries are ignored by this script, and should be first eliminated with linkRedir(1). The main input is the D form for documents and their links and link text D <URL> <HASHID> <TITLE> <OUTGOING-URL> <LINK-TEXT> ... EOL <TYPE> <TOKEN> ... EOD

The text "EOD" acts as a document terminator and can be missing if no tokens exist. The text "EOL" is a link terminator. The <URL>s and <HASHID>s must not have spaces or the processing will get confused since R and D records are split on spaces. Note text at the end of the line is an exception. <HASHID> is any externally defined record identifier. ALVIS default is a 32 character hexadecimal from an MD5 hash of the text.

<TYPE> is intended to be a short bit of alphabetic text describing the type such as 'person', 'company', etc. Reserved <TYPE>s are 'doc', link to a document in the collection, 'link' which is a link out of the collection, and 'text' which is any text.
