....independently developed very similar formalisms for corpus searching (so potentially also for textual specifications in lexicons) They are XKWIC CQP (Schulze and Christ, 1994) from IMS, Stuttgart ( Xkwic ) the ALEMBIC workbench (Day et al. 1997) from MITRE Corp. AWB ) and Mother of Perl (Doran et al. 1997) from U Penn ( MOP ) 5 First, a disclaimer noting the differences. Xkwic was produced for linguists and lexicographers, whereas AWB and MOP were produced for rapid development of Information Extraction systems. MOP assumes its users are programmers, so makes less concessions to userfriendliness ....

....Also, the relative order of the subject and the verb can also be reversed as in (7.14) The XTAG grammar distinguishes such adverbial constructions from the sentence complement construction by assigning different supertags to the verb. A detailed analysis of this construction is presented in [Doran, 1996]. The task of the supertagger is to disambiguate among the sentence complement supertag and the various adverbial supertags for the verb given the context of the sentence. Table 7.4 presents the performance results of the supertagger on this task. Once again the baseline of selecting the most ....
....information. A detailed description of each of these components of the system is provided in [Baldwin et al. 1996] A pattern description language called 2 The fields of this template were not identical to those in the corresponding MUC 6 template [Committee, 1995] Mother of PERL (MOP) [Doran et al. 1996] has also been developed in conjunction with the EAGLE system. MOP allows a user to specify patterns using the different levels of syntactic descriptions provided by the EAGLE system to spot information relevant to fill the fields of a template. The supertagger is used in EAGLE as one of the two ....

....not localized but was distributed throughout a document. The text which triggered a pattern to fire is sometimes far from the fragment of text needed to fill one slot of the template. Our approach to information extraction was highly syntactic and relied on a pattern matching language called MOP [Doran et al. 1996], which had access to various types of analysis including part of speech tags and parse trees. One way to address the problem of needing distant information to complete a template in this system would involve structuring texts prior to performing information extraction. Then, when filling ....
