semantica:基于 Python 的 AI 上下文图与决策智能框架项目

通过统一接口，从文件、网页、数据库、API、流数据、邮件、Git 仓库、Parquet、Databricks、Snowflake、SAP 或 MCP 服务器接入数据。

from semantica.ingest import FileIngestor, WebIngestor, ParquetIngestor, DBIngestor

# Ingest an entire directory of contracts (PDF, DOCX, HTML, TXT)
docs = FileIngestor().ingest_directory("./contracts/", recursive=True)

# Ingest live web content with robots.txt compliance
pages = WebIngestor().ingest_url("https://example.com/reports/annual-2024.html")

# Ingest structured data from Parquet with Snappy compression
records = ParquetIngestor().ingest("./data/transactions.parquet")

# Ingest from a SQL database - specify which tables to pull
rows = DBIngestor().ingest_database(
    connection_string="postgresql://user:pass@localhost/mydb",
    include_tables=["customer_events"],
    max_rows_per_table=50_000,
)

# Enterprise data platforms - pull tables straight out of your lakehouse
# or warehouse, with lineage, instead of exporting to CSV first
from semantica.ingest import DatabricksIngestor, SnowflakeIngestor

# pip install "semantica[db-databricks]"
databricks = DatabricksIngestor(
    host="https://adb-xxx.azuredatabricks.net",
    token="dapi-xxxxxxxx",              # or client_id/client_secret for OAuth M2M
    http_path="/sql/1.0/warehouses/xxxxxxxx",
    catalog="main",
)
customers    = databricks.ingest_table("customers", limit=10_000)
sales        = databricks.ingest_query("SELECT * FROM sales WHERE region = 'EMEA'")

安全提示： 切勿在生产代码中硬编码凭据（token、password、private_key）；请通过环境变量（例如 DATABRICKS_TOKEN、SNOWFLAKE_PASSWORD）或密钥管理器传入。

支持的数据源： 本地文件（PDF、DOCX、PPTX、HTML、TXT、CSV、JSON、YAML、Excel、XML） · 网页 · RSS/Atom 源 · REST API · 数据库（PostgreSQL、MySQL、SQLite、Oracle、SQL Server） · Parquet 数据集 · Databricks（Unity Catalog + Delta Lake） · Snowflake · SAP（OData v2/v4） · Git 仓库 · 电子邮件（IMAP/POP3） · 消息流（Kafka、RabbitMQ、Kinesis、Pulsar） · MCP 资源 · Apache Arrow/Feather/IPC（ArrowIngestor）

DuckDB、Elasticsearch、Google Drive、HuggingFace、MongoDB 和 Pandas 的数据摄取也已随附（DuckDBIngestor、ElasticIngestor、GDriveIngestor、HuggingFaceIngestor、MongoIngestor、PandasIngestor），但尚未从顶层 semantica.ingest 命名空间重新导出——请直接导入：from semantica.ingest.duckdb_ingestor import DuckDBIngestor。

一次处理即可从原始文本中提取结构化知识。

)

text = """
Anthropic CEO Dario Amodei announced a $7.3B Series E funding round in partnership
with Google and Spark Capital, valuing the company at $61.5B as of Q4 2024.
"""

# Named entity recognition with confidence thresholding
ner = NamedEntityRecognizer(confidence_threshold=0.7)
entities = ner.extract_entities(text)
# → [Entity(name="Dario Amodei", type="PERSON"), Entity(name="Anthropic", type="ORG"),

# → [("Anthropic", "valuation", "$61.5B"), ("Dario Amodei", "is_ceo_of", "Anthropic"), ...]

对多个文档进行批处理时，请使用 ner.process_batch([...])，而不是在门面类上逐次调用 extract_entities_batch。

从文档构建生产级知识图谱，并在其上运行图算法。

当前局限： ReteEngine 的 alpha 节点条件匹配器在本次发布中有意保持简单——在将其接入生产环境合规关口之前，请结合实际规则集验证 match_patterns() 的输出；更具选择性的条件评估已列入路线图。

在构建知识图谱之前，对文本、实体、日期、数字和编码进行标准化。

# Natural language date parsing with timezone conversion

将数据摄取、信息抽取与图谱构建组合为声明式并行流水线。
