||||
with open(log_path, "r", encoding="utf-8") as f:
|
||||
content = f.read().strip()
|
||||
if content:
|
||||
documents.append(Document(
|
||||
page_content=content,
|
||||
metadata={"source": str(log_path.relative_to(input_dir))}
|
||||
))
|
||||
|
||||
# Create vectorstore
|
||||
embedding_model = HuggingFaceEmbeddings(model_name="sentence-transformers/all-MiniLM-L6-v2")
|
||||
text_splitter = CharacterTextSplitter(chunk_size=1000, chunk_overlap=200)

||||
|
||||
vectorstore = Chroma.from_documents(
|
||||
documents=chunks,
|
||||
embedding=embedding_model,
|
||||
persist_directory="chroma_logs"
|
||||
)
|
||||
```
|
||||
|
||||
**2D Visualization:**
|
||||
```python
|
||||
# Create 2D visualization
|
||||
from sklearn.manifold import TSNE
|
||||
import plotly.express as px
|
||||
|
||||
result = vectorstore.get(include=['embeddings', 'metadatas', 'documents'])
|
||||
X = np.array(result['embeddings'])
|
||||
X_2d = TSNE(n_components=2, perplexity=min(30, X.shape[0] - 1), random_state=42).fit_transform(X)
|
||||
|
||||
fig = px.scatter(
|
||||
x=X_2d[:, 0],
|
||||
y=X_2d[:, 1],
|
||||
color=[meta['source'] for meta in result['metadatas']],

|
||||
|
||||
**Features:**
|
||||
- Pandas CSV processing
|
||||
- Structured data extraction
|
||||
- Semantic search across records
|
||||

||||
3,Item C,Standard product,Office,50
|
||||
```
|
||||
|
||||
**Usage:**
|
||||
```python
|
||||
import pandas as pd
|
||||
|
||||
# Load CSV files and convert to documents
|
||||
for csv_path in input_dir.rglob("*.csv"):
|
||||
df = pd.read_csv(csv_path)
|
||||
|
||||
if "Name" in df.columns and "Description" in df.columns:
|
||||
records = [
|
||||
f"{row['Name']}: {row['Description']}"
|
||||
for _, row in df.iterrows()
|
||||
if pd.notna(row['Description'])
|
||||
]
|
||||
else:
|
||||
records = [" ".join(str(cell) for cell in row) for _, row in df.iterrows()]
|
||||
|
||||
content = "\n".join(records).strip()
|
||||
|
||||
if content:
|
||||
documents.append(Document(
|
||||
page_content=content,
|
||||
metadata={"source": str(csv_path.relative_to(input_dir))}
|
||||
))
|
||||
|
||||
vectorstore = Chroma.from_documents(
|
||||
documents=documents,
|
||||
embedding=embedding_model,
|
||||
persist_directory="chroma_csv_data"
|
||||
)
|
||||
```
|
||||
|
||||
**2D Visualization:**
|
||||
```python
|
||||
# Extract file IDs for labeling
|
||||
def extract_file_id(path_str):
|
||||
return Path(path_str).stem
|
||||
|
||||
sources = [extract_file_id(meta['source']) for meta in all_metas]
|
||||
|
||||
fig = px.scatter(
|
||||
x=X_2d[:, 0],
|
||||
y=X_2d[:, 1],
|
||||
color=sources,
|
||||
hover_data={"preview": [doc[:200] for doc in all_docs]}
