TOOLS Based on the data described above, we constructed a set of tools that all aim at the enrichment of the lexical data, both the amount of lexical entries and the richness and thje accuracy of their description Tools are described useing the following data structure: name of the program programming language(s) used developer(s) a short description of the program availability a. text handling First of all a full text data base, developed by a student of computer science, serves the tasks of administering texts and generating intermediate results. This tool as all the others follow the UNIX philosphy of modularizationan and combinablity. Standard interface is the UNIX command shell. So the tools in any combination needed could be embedded into an X-Window or Motif interface. Programs written in C respect the ANSI-C standard. They do not use special libraries. freq C Humanist package developers generation of word type frequency lists from corpus texts. yes kwic C, reimplementation in C++ Johannes Prinz a grep-like program, tailored for the needs of the lexicographer. The program identifies strings according to a regular expression (or a combination of them) in a corpus and extracts this strings in a contexts of a size definable by the user. Dump in files or pretty printing possible. yes tag C, SQL Lothar Lemnitzer Tagging of all word forms found in a concardance by simple dictionary look up. Lemma and part of speech are added to each word form. The program keeps track of word forms not yet found in the dictionary data base. no stat C, SQL Lothar Lemnitzer Based ot the output of tag, statistical figures about cooccurence probabilities of the key word with any other word are computed. Methods used up to now are mutual information index and t-score test. no b. conversion tools FAZ2DTD C, LEX Lothar Lemnitzer. Peter Lisowski Conversion of FAZ printing tapes to articles structured according to Document Type Definition (DTD) yes ZEIT2DTD C, LEX Lothar Lemnitzer, Christian Mueller-Boehm Conversion of ZEIT printing tapes to articles structured according to Document Type Definition (DTD) yes VDI2DTD C, LEX Lothar Lemnitzer Conversion of vdi-nachrichten printing tapes to articles structured according to Document Type Definition (DTD) no PAIS2DTD C, LEX Lothar Lemnitzer , Antonio Moreno Conversion of EL PAIS printing tapes to articles structured according to Document Type Definition (DTD) yes c. Lexion import tools DICTPARS C, LEX, YACC, SQL Lothar Lemnitzer , Dietmar Stosik Conversion of sample entries of a bilingual dictionary (German-Spanish) with fully fledged informations structure into an SGML-format. Extractiona of pieces of information from this structure to store them into fields in a relational database according to Document Type Definition (DTD) no
