### Generated via
- [llamapun 0.2.0](https://github.com/KWARC/llamapun/releases/tag/0.2.0),
- [GloVe 1.2, 2018](https://github.com/stanfordnlp/GloVe/tree/07d59d5e6584e27ec758080bba8b51fce30f69d8)
### Generation Parameters
* token model distributed as 3 subsets - no_problem, warning and error. complete model is derived via:
```
cat token_model_no_problem.txt \
token_model_warning.txt \
token_model_error.txt > token_model_complete.txt
```
* [llamapun v0.2](https://github.com/KWARC/llamapun/releases/tag/0.2), `corpus_token_model` example used for token model extraction
* processed logical paragraphs only (excluded non-textual modalities, e.g. tables, figures and their captions, bibliographies, as well as abstracts)
* excluded paragraphs containing latexml errors (marked via a `ltx_ERROR` HTML class)
* used llamapun math-aware sentence and word tokenization, with subformula math lexemes
* marked up inline citations replaced with `citationelement` token
* numeric literals replaced with `NUM` token (both in text and formulas)
* ignored sentences with unnaturally long words (>25 characters) - almost always due to latexml conversion errors
* [GloVe repository at sha 07d59d](https://github.com/stanfordnlp/GloVe/tree/07d59d5e6584e27ec758080bba8b51fce30f69d8)

### Examples and baselines
#### GloVe in-built evaluation (non-expert tasks e.g. language, relationships, geography)
1. no_problem
* Total accuracy: 27.47% (4028/14663)
* Highest score: "gram3-comparative.txt", 75.30% (1003/1332)
2. warning
* Total accuracy: 31.97% (5351/16736)
* Highest score: "gram3-comparative.txt", 77.40% (1031/1332)
3. error
* Total accuracy: 29.67% (4910/16549)
* Highest score: "gram3-comparative.txt", 72.75% (969/1332)
4. complete
* Total accuracy: 35.48% (6298/17750)
* Highest score: "gram3-comparative.txt", 76.65% (1021/1332)
5. demo baseline: text8 demo (first 100M characters of Wikipedia)
* Total accuracy: 23.62% (4211/17827)
* Highest score: "gram6-nationality-adjective.txt", 58.65% (892/1521)
**Evaluation note:** These in-built evlauation runs are provided as a sanity check that the generated GloVe models pass a basic baseline against the non-expert tasks in the default GloVe suite.
One would need a scienctific discourse tailored set of test cases to evaluate the arXiv-based models competitively.
#### Measuring word analogy
In a cloned GloVe repository, start via:
```
python2 eval/python/word_analogy.py --vocab_file vocab.arxmliv.txt --vectors_file glove.arxmliv.11B.300d.txt
```
1. `abelian` is to `group` as `disjoint` is to `?`
* Top hit: `union`, cosine distance `0.653377`
2. `convex` is to `concave` as `positive` is to `?`
* Top hit: `negative`, cosine distance `0.786877`
3. `finite` is to `infinte` as `abelian` is to `?`
* Top hit: `nonabelian`, cosine distance `0.676042`
4. `quantum` is to `classical` as `bottom` is to `?`
* Top hit: `top`, cosine distance `0.734896`
5. `eq` is to `proves` as `figure` is to `?`
* Top hit: `showing`, cosine distance `0.668502`
6. `italic_x` is to `italic_y` as `italic_a` is to `?`
* Top hit: `italic_b`, cosine distance `0.902608`
