### Dataset Summary
CSQA corpus (Complex Sequential Question-Answering, see https://amritasaha1812.github.io/CSQA/) is a large corpus for conversational knowledge-based question answering. The version here is augmented with various fields to make it easier to run specific tasks, especially SPARQL-to-text conversion.
The original data has been post-processing as follows:
1. Verbalization templates were applied on the answers and their entities were verbalized (replaced by their label in Wikidata)
2. Questions were parsed using the CARTON algorithm to produce a sequence of action in a specific grammar
3. Sequence of actions were mapped to SPARQL queries and entities were verbalized (replaced by their label in Wikidata)
### Supported tasks
- Knowledge-based question-answering
- Text-to-SPARQL conversion
#### Knowledge based question-answering
Below is an example of dialogue:
- Q1: Which occupation is the profession of Edmond Yernaux ?
- A1: politician
- Q2: Which collectable has that occupation as its principal topic ?
- A2: Notitia Parliamentaria, An History of the Counties, etc.
#### SPARQL queries and natural language questions
```SQL
SELECT DISTINCT ?x WHERE
{ ?x rdf:type ontology:occupation . resource:Edmond_Yernaux property:occupation ?x }
```
is equivalent to:
```txt
Which occupation is the profession of Edmond Yernaux ?
```
### Languages
- English
## Dataset Structure
The corpus follows the global architecture from the original version of CSQA (https://amritasaha1812.github.io/CSQA/).
There is one directory of the train, dev, and test sets, respectively.
Dialogues are stored in separate directories, 100 dialogues per directory.
Finally, each dialogue is stored in a JSON file as a list of turns.

### Data splits
Text verbalization is only available for a subset of the test set, referred to as *challenge set*. Other sample only contain dialogues in the form of follow-up sparql queries.
| | Train | Validation | Test |
| --------------------- | ---------- | ---------- | ---------- |
| Questions | 1.5M | 167K | 260K |
| Dialogues | 152K | 17K | 28K |
| NL question per query | 1 |
| Characters per query | 163 (± 100) |
| Tokens per question | 10 (± 4) |
### JSON fields
Each turn of a dialogue contains the following fields:
#### Original fields
* `ques_type_id`: ID corresponding to the question utterance
* `description`: Description of type of question
* `relations`: ID's of predicates used in the utterance
* `entities_in_utterance`: ID's of entities used in the question
* `speaker`: The nature of speaker: `SYSTEM` or `USER`
* `utterance`: The utterance: either the question, clarification or response
* `active_set`: A regular expression which identifies the entity set of answer list
* `all_entities`: List of ALL entities which constitute the answer of the question
* `question-type`: Type of question (broad types used for evaluation as given in the original authors' paper)
* `type_list`: List containing entity IDs of all entity parents used in the question
#### New fields
* `is_spurious`: introduced by CARTON,
* `is_incomplete`: either the question is self-sufficient (complete) or it relies on information given by the previous turns (incomplete)
* `parsed_active_set`:
* `gold_actions`: sequence of ACTIONs as returned by CARTON
* `sparql_query`: SPARQL query
#### Verbalized fields
Fields with `verbalized` in their name are verbalized versions of another fields, ie IDs were replaced by actual words/labels.
### Format of the SPARQL queries
* Clauses are in random order
* Variables names are represented as random letters. The letters change from one turn to another.
* Delimiters are spaced
