254aba33a1 pgf_reader_done should do nothing if the reading has failed 2013-11-15 08:59:18 +00:00

1d7b6f44b6 added Predef.SOFT_BIND. This special token allows zero or more spaces between ordinary tokens. It is also used in the English RGL to attach the commas to the previous word. 2013-11-12 09:54:57 +00:00

6729cca568 factor of 3 speedup for the translation without slowing down the grammar loading. The parser still seems to be 8 times slower than before I introduced the BIND. At least the Android UI now feels a lot more comfortable 2013-11-07 11:14:32 +00:00

475f213c99 the content of ParseEngAbs3.probs is now merged with ParseEngAbs.probs. The later is now retrained. Once the grammar is compiled with the .probs file now it doesn't need anything more to do robust parsing. The robustness itself is controlled by the flags 'heuristic_search_factor', 'meta_prob' and 'meta_token_prob' in ParseEngAbs.gf 2013-11-06 10:21:46 +00:00

43fb9b3b7a added the linref construction in GF. The PGF version number is now bumped 2013-10-30 12:53:36 +00:00

b058fdd17d a major redesign in the C runtime. The parser and the linearizer now fully support BIND. The following things are still broken: parseval, word completion, handling 'pre', the robust mode 2013-10-09 12:08:51 +00:00

2f78333e28 GuString is now an ordinary C string - it makes live easier. In addition PgfSymbolKS, PgfExprFun and PgfLiteralStr now keep their strings as embedded flexible arrays. The latest change gives us the same compactness as the old representation but it is a lot easier to use. 2013-10-04 12:04:39 +00:00

efa4bc4d62 a major refactoring in the C and the Haskell runtimes. Note incompatible change in the PGF format!!!
The following are the outcomes:

   - Predef.nonExist is fully supported by both the Haskell and the C runtimes

   - Predef.BIND is now an internal compiler defined token. For now
     it behaves just as usual for the Haskell runtime, i.e. it generates &+.
     However, the special treatment will let us to handle it properly in 
     the C runtime.

   - This required a major change in the PGF format since both 
     nonExist and BIND may appear inside 'pre' and this was not supported
     before.

0d68a20d94 a complete Python API for reading, printing and manipulation of abstract trees and types. This includes dependent types, high-order abstract syntax and implicit arguments 2013-06-27 09:39:15 +00:00

03690ccc4b we no longer maintain an explicit list of functions per category since now it is implicitly kept in the JIT compiled code 2013-06-26 09:35:50 +00:00

16584d4368 Now there is a just-in-time compiler which generates native code for proof search. This is already used by the exhaustive generator. The time to generate 10000 abstract trees with ParseEng went down from 4.43 sec to 0.29 sec. 2013-06-25 19:22:42 +00:00

3be31c62e9 a new reasoner in the C runtime. It supports tabling which makes it decideable for propositional logic. dependent types and high-order types are not supported yet. The generation is still in decreasing probability order 2013-01-07 12:50:32 +00:00

18fe8af964 now the meta probability for a category is explicitly specified in the statistical model instead of computed internally. this avoids rounding errors while computing the sum of a large number of small values. 2012-09-24 09:37:21 +00:00

7549a4876d now there is a limit of 2000000 items in the chart of the robust parser. This prevents from explosion in the memory size but it will also prevent us from parsing some sentences. 2012-06-12 11:30:01 +00:00
