# Corpus Analysis

## Start einer Session

```javascript
nopaque.socket.emit("corpus_analysis_init", <corpusId>);
  <corpusId> ~ number
// Show init loading modal

nopaque.socket.on("corpus_analysis_init", <response>);
  <response> ~ {"code": <code>, "msg": <message>}
  <code> ~ number // HTTP status code
  <msg> ~ string
// Hide init loading modal
```

## Ausführen einer Suchanfrage

Ergebnisse werden Stückchenweise als "chunks" übertragen.

```javascript
nopaque.socket.emit("corpus_analysis_query", <query>);
  <query> ~ string
// Clear result data store and list
result = {"query": <query>};
// Hide query result card
// Show query loading card
nopaque.socket.on("corpus_analysis_query", <response>);
  <response>: {"code": <code>, "result": <result>}
  <code> ~ number // Error, Success
  <result> ~ {"matches": [<cpos>, ...],
              "num_matches": <num_matches>,
              "cpos_lookup": {<cpos>: <token>, ...},
              "text_lookup": {<textId>: <text>, ...}}
  <cpos> ~ number
  <num_matches> ~ number
  <token> ~ {"word": <word>, "lemma": <lemma>, "simple_pos": <simple_pos>, "pos": <pos>, "ner": <ner>, "text": <textId>, "s": <sId>}
  <word> ~ string
