Task and Method are words included in the Sentence. Words must be found in sentences, not inventing new words. The same words cannot be used for Task and Method.

Sentence A : It is often assumed that when  natural language processing  meets the real world, the ideal of aiming for complete and correct interpretations has to be abandoned. However, our experience with  TACITUS  ; especially in the  MUC-3 evaluation  , has shown that principled techniques for  syntactic and pragmatic analysis  can be bolstered with methods for achieving robustness. We describe three techniques for making  syntactic analysis  more robust---an  agenda-based scheduling parser  , a  recovery technique for failed parses  , and a new technique called  terminal substring parsing  . For  pragmatics processing  , we describe how the method of  abductive inference  is inherently robust, in that an interpretation is always possible, so that in the absence of the required  world knowledge  , performance degrades gracefully. Each of these techniques have been evaluated and the results of the evaluations are presented. 
Task : natural language processing, syntactic and pragmatic analysis, syntactic analysis
Method : TACITUS, agenda-based scheduling parser, recovery technique, terminal substring parsing,abductive inference

Sentence B : A proposal to deal with  French tenses  in the framework of  Discourse Representation Theory  is presented, as it has been implemented for a fragment at the  IMS . It is based on the  theory of tenses  of NAME_1. NAME_2 and NAME_3. Instead of using  operators  to express the  meaning  of the  tenses  the Reichenbachian point of view is adopted and refined such that the impact of the  tenses  with respect to the  meaning  of the  text  is understood as contribution to the integration of the  events  of a  sentence  in the  event structure  of the preceeding  text . Thereby a  system of relevant times  provided by the preceeding  text  and by the  temporal adverbials  of the  sentence  being processed is used. This system consists of one or more  reference times  and  temporal perspective times , the  speech time  and the  location time . The special interest of our proposal is to establish a plausible choice of anchors for the  new event  out of the  system of relevant times  and to update this  system of temporal coordinates  correctly. The problem of choice is largely neglected in the literature. In opposition to the approach of NAME_2 and NAME_4 the exact  meaning  of the  tenses  is fixed by the  resolution component   The response should be in all capital letters.
