10 Grunnstruktur i trrekkstruklturene:

11 Full struktur for ”John sees Mary”:

12 Bottom-up parsing: only a partial analysis may result:

14 Maximal analyses are found:

15 Bottom-up parsing: only a partial analysis may result: Maximal analyses are found:

16 Bottom-up parsing: only a partial analysis may result: Maximal analyses are found: Each edge (= tree) in each maximal analysis is translated separately

17 Result of a parse: tree with associated features:

18 LEXICON COMPARISON

19 GRAMMAR COMPARISON

20 The full translation process

21 Parse with target pointers Mode 1 Output: "Mozart skremmer den hunden"

22 Mode 1 and 2 generation Overwrite target stems at leaf nodes

23 Mode 1, 2 and 3 generation Insert compatible word forms at terminal nodes

24 Handled in Mode 1: Agreement Source/target gender clashes Syncretisms in source paradigms

25 Parse with target pointers Mode 2

26 Mode 2 generation Splice in target subtrees

27 Parse with target pointers Mode 3

28 Mode 3 generation, Stage I Input situation schema:

29 Target rule structure: Target stem entry:

30 Result of unification Unification points for further structures are identified

31 Mode 3 generation, Stage II

32 Mode 3 generation, Stage III Alternative word forms at terminal nodes
