v4.5.10 - Remove Patterns / Lucene and add Semgrex / Ssurgeon features

Remove Patterns

• Older versions of Lucene have a security issue: GHSA-g643-xq6w-r67c Unfortunately, Lucene V9.12 is not compatible with Java 8. We therefore want to remove Lucene from this release
• The one project using it in CoreNLP is the patterns directory. We remove this, perhaps temporarily. If you are making use of the patterns project, please file an issue and we will include it in a future Java 11 compatible release. (We are aware of at least one group which used that project, back in 2020)

Semgrex and Ssurgeon upgrades

• :: uniq operator at the end of a Semgrex expression allows for making results uniq across a set of node values
• <> search in Semgrex means connected either as parent or child. Simplifies expressions where the direction of the connection doesn't matter
• Ssurgeon EditNode now supports -removemorphofeatures to remove one or more features without removing all features
• Ssurgeon SplitWord now allows for exact word splitting, not just regex based splitting
• Ssurgeon MergeNodes can now merge multiple nodes at once, not just two
• add Ssurgeon SetPhraseHead operation to make a connected phrase in a dependency graph have a different head, possibly updating the relations between the children as well. Useful for changing the head of a proper noun phrase, for example

Hopefully minor interface changes

• We move VariableStrings from trees/tregex and semgraph/semgrex into util. It turns out there were two copies of this code in the codebase. This may ruin serialized tregex outputs, if such a thing exists.

v4.5.9 - Security Updates and Semgrex / Ssurgeon features

Security updates

• Removed the ability to specify an external library for deserialization of annotations in the server. We believe this should not be necessary given the complete nature of the protobuf format, and this was reported as a potential security vulnerability: https://github.com/stanfordnlp/CoreNLP/security/advisories/GHSA-wv35-hv9v-526p If it turns out someone has a use case for this feature, please file an issue on github.
• Remove the naturalli demo, which is unsupported and likely not used anywhere given its Stanford-specific components

Semgrex / Ssurgeon features

• Semgrex can now search on negated attributes of a node using !: as the syntax: 7399e9b
• Semgrex can now search on maps (especially morphological features) with the :{feature:value} syntax, as well as search for negative matches with {feature!:value}: 84ac932 ff1d903 3c30b3b
• Ssurgeon can now reindex nodes with ReindexGraph, such as in cases where a sentence was manually split in a conllu file: 156fad1
• Ssurgeon can remove a feature with EditNode using the -remove option: 8e7d121

Other minor updates

• Additional demonyms now supported in the lemmatizer, demonyms from LinES and ParTUT: 4f15b08
• Output lemmas when training a tagger whenever available if -outputLemmas is set, even if not verbose 94739c7

v4.5.8 - Package updates and minor bug fixes

• Update German UD POS tagger to UD 2.14 data

• Add Austrian German month names to the German tokenizer: #1454 Thank you @j3ernhard

• Improve the constituency to dependency converter to remove quite a few validation errors. This includes adding the PTB Corrector as an earlier step when operating specifically on PTB data #1445

• SSurgeon feature to split one word into multiple words: 13ede5a

• Unravel recursion in SemanticGraph - 05804a3 Fixes one server crash observed in #1461

• Package updates: update protobuf -> 3.25.5, javax -> 1.1.6 #1465 Unfortunately updating Lucene to fix all dependency security issues will require dropping Java 8 support

• Fix the server caching of tokenizer annotators to include segmenter properties as well. Avoids the server not respecting a request for a different segmentation model. 6f6eb93

• include the Morphology CLI for using the CoreNLP lemmatizer from elsewhere, such as Python

v4.5.3: Ssurgeon interface, Collinizer fixes
