## Benchmark Highlights
GISA is a benchmark for General Information-Seeking Assistants with 373 human-crafted queries that reflect real-world information needs. It includes both stable and live subsets, four structured answer formats (item, set, list, table), and complete human search trajectories for every query.
- **Diverse answer formats with deterministic evaluation.**  
  GISA uses four structured answer types (item, set, list, table) with strict matching metrics for reproducible evaluation, avoiding subjective LLM judging while preserving task diversity.
- **Unified deep + wide search capabilities.**  
  Tasks require both vertical reasoning and horizontal information aggregation across sources, evaluating long-horizon exploration and summarization in one benchmark.
- **Dynamic, anti-static evaluation.**  
  Queries are split into stable and live subsets; the live subset is periodically updated to reduce memorization and keep the benchmark challenging over time.
- **Process-level supervision via human trajectories.**  
  Full human search trajectories are provided for every query, serving as gold references for process reward modeling and imitation learning while validating task solvability.

## Evaluation
Please refer to our [GitHub](https://github.com/RUC-NLPIR/GISA).

## Data Schema

#### 1. encrypted_question.jsonl
Each row contains:

- id (int): the ID of the question (it is **not** continuous)
- question (str): the question after encryption
- answer_type (str): the type of the answer, can be item, set, list, or table
- question_type (str): the type of the question, can be stable or live
- topic (str): the topic of the question, can be TV Shows \& Movies, Science \& Technology, Art, History, Sports, Music, Video Games, Geography, Politics, or Other
- canary (str): the password used for decryption
  
#### 2. answer/[id].csv
The file contains the answer corresponds to the question [id].

#### 3. trace/[id].json
The file conatins the human trajectory of the question [id], with the following keys:

- search (list): the queries issued by the annotator
- result (dict): the search result of each query
- click (list): the click behaviors made by the annotator

## Loading Method

```python
def derive_key(password: str, length: int) -> bytes:
    hasher = hashlib.sha256()
    hasher.update(password.encode())
    key = hasher.digest()
    return key * (length // len(key)) + key[: length % len(key)]

def decrypt(ciphertext_b64: str, password: str) -> str:
    encrypted = base64.b64decode(ciphertext_b64)
    key = derive_key(password, len(encrypted))
    decrypted = bytes(a ^ b for a, b in zip(encrypted, key))
    return decrypted.decode()

obj["question"] = decrypt(str(obj["question"]), str(obj["canary"]))
```
