MONO91 Problems of Evaluation chapter Mary Elizabeth Stevens National Bureau of Standards it deals only with data of a limited corpus. The scope of the problem and statements by some other authors are presented. The procedure of investigation involved a study of adverbial sequences and occurrences of adverbials in reference to verbals. Four classification sort- ings were used to aid the study. Tentative adverbial function classes were assumed. The results of the first three sortings were used to modify the tentative function classes. Tentative position classes were established. The fourth sorting was used to establish function-position classes. (Author) AD-408 938 Div. 32, 15, 5 (TISTP/AW) Linguistics Research Center, U. of Texas, Austin.

Mallios. 28 Sep 62, 36p. Contract D[OCRerr]18 064cm12810, Task I Unclassified report No automatic release to foreign nationals. Descriptors: (eStatistical analysis, Biologi- cal. assay), Test methods, Tolerances, Distri- bution, Scientific research, Population. In Section I, the moments of a normalized toler- ance distribution are estimated by utilizing ex- perimental technique deaths in the indirect as- say. More precisely, the information gained by assuming that the probability of experimental technique deatha is independent of dosage may, in general, yield an LD5O with greater precision. Adjustments are given for nonconatant natural mortality over time. A preliminary report on bi- modal tolerance distribution is also given.

LRC63 WDE1 Grant NSF GN54 Unclassified report Descriptors: (*Vocabulary, Classification), (*Language, Analysis) Research conducted in connection with the classi- fication of adverbials is presented in this paper. The resulting classification is tenta- tive because, among other reasons, it deals only with data of a limited corpus. The scope of the problem and statements by some other authors are presented. The investigation involved a study of adverbial sequences and occurrences of adverbials in reference to verbals. Four classification sortings were used to aid the study. Tentative adverbial function classes were assumed. The results of the first three sortings were used to modify the tentative function classes. Tentative position classes were estab- lished. The fourth sorting was used to establish function-position classes. Criteria for de- Figure 8b. Exarr[OCRerr]p1es of Duplicate Indexing 162
