+
### Processing Pipeline
|
52 |
+
|
53 |
+
1. Install Dependencies:
|
54 |
+
```bash
|
55 |
+
pip install requests tqdm concurrent.futures
|
56 |
+
```
|
57 |
+
|
58 |
+
2. Run Content Processor:
|
59 |
+
```bash
|
60 |
+
python process.py --input corpus.jsonl --output results.jsonl --threads 24
|
61 |
+
```
|
62 |
+
|
63 |
+
### Client Implementation
|
64 |
+
|
65 |
+
```python
|
66 |
+
import requests
|
67 |
+
|
68 |
+
def classify_content(text: str, vllm_url: str = "http://localhost:6002/v1/completions") -> dict:
|
69 |
+
xml_content = (
|
70 |
+
'<instruction>Determine true or false if the following content is '
|
71 |
+
'suitable and should be indexed.</instruction>\n'
|
72 |
+
'<suitable>\n'
|
73 |
+
f' <content>{text}</content>'
|
74 |
+
)
|
75 |
+
|
76 |
+
response = requests.post(
|
77 |
+
vllm_url,
|
78 |
+
json={
|
79 |
+
"prompt": xml_content,
|
80 |
+
"max_tokens": 6000,
|
81 |
+
"temperature": 1,
|
82 |
+
"model": "lora",
|
83 |
+
"stop": ["</suitable>"]
|
84 |
+
},
|
85 |
+
timeout=30000
|
86 |
+
)
|
87 |
+
|
88 |
+
completion = response.json()["choices"][0]["text"]
|
89 |
+
|
90 |
+
# Parse XML tags
|
91 |
+
import re
|
92 |
+
def extract_tag(tag: str) -> str:
|
93 |
+
match = re.search(f'<{tag}>(.*?)</{tag}>', completion, re.DOTALL)
|
94 |
+
return match.group(1).strip() if match else ""
|
95 |
+
|
96 |
+
return {
|
97 |
+
"thinking": extract_tag("thinking"),
|
98 |
+
"category": extract_tag("category"),
|
99 |
+
"should_index": extract_tag("should_index")
|
100 |
+
}
|
101 |
+
```
|
102 |
+
|
103 |
+
### Example Usage
|
104 |
+
|
105 |
+
```python
|
106 |
+
text = """Multiservice Tactics, Techniques, and Procedures
|
107 |
+
for
|
108 |
+
Nuclear, Biological, and Chemical Aspects of Consequence
|
109 |
+
Management
|
110 |
+
|
111 |
+
TABLE OF CONTENTS..."""
|
112 |
+
|
113 |
+
result = classify_content(text)
|
114 |
+
print(result)
|
115 |
+
```
|
116 |
+
|
117 |
+
Example output:
|
118 |
+
```json
|
119 |
+
{
|
120 |
+
"thinking": "This is a table of contents for a document, not the actual content.",
|
121 |
+
"category": "table of contents",
|
122 |
+
"should_index": "false"
|
123 |
+
}
|
124 |
+
```
|
125 |
+
|
126 |
+
## Batch Processing
|
127 |
+
|
128 |
+
The included processor supports parallel processing of JSONL files:
|
129 |
+
|
130 |
+
```python
|
131 |
+
from request_processor import RequestProcessor
|
132 |
+
|
133 |
+
processor = RequestProcessor(
|
134 |
+
input_file="corpus.jsonl",
|
135 |
+
output_file="results.jsonl",
|
136 |
+
num_threads=24
|
137 |
+
)
|
138 |
+
processor.process_file()
|
139 |
+
```
|
140 |
+
|
141 |
+
Input JSONL format:
|
142 |
+
```json
|
143 |
+
{
|
144 |
+
"pid": "document_id",
|
145 |
+
"docid": "path/to/source",
|
146 |
+
"content": "document text",
|
147 |
+
"metadata": {
|
148 |
+
"key": "value"
|
149 |
+
}
|
150 |
+
}
|
151 |
+
```
|
152 |
+
|
153 |
+
Output JSONL format:
|
154 |
+
```json
|
155 |
+
{
|
156 |
+
"pid": "document_id",
|
157 |
+
"docid": "path/to/source",
|
158 |
+
"content": "document text",
|
159 |
+
"metadata": {
|
160 |
+
"key": "value"
|
161 |
+
},
|
162 |
+
"thinking": "reasoning process",
|
163 |
+
"category": "content type",
|
164 |
+
"should_index": "true/false",
|
165 |
+
"processed_at": "2024-10-22 02:52:33"
|
166 |
+
}
|
167 |
+
```
|
168 |
+
|
169 |
+
## Performance Considerations
|
170 |
+
|
171 |
+
- Uses thread pooling for parallel processing
|
172 |
+
- Implements atomic writes with file locking
|
173 |
+
- Progress tracking with tqdm
|
174 |
+
- Automatic error handling and logging
|
175 |
+
- Configurable thread count for optimization
|
176 |
+
|
177 |
+
## Error Handling
|
178 |
+
|
179 |
+
Errors are captured in the output JSONL:
|
180 |
+
```json
|
181 |
+
{
|
182 |
+
"error": "error message",
|
183 |
+
"processed_at": "timestamp"
|
184 |
+
}
|
185 |
+
```
|
186 |
+
|
187 |
+
Monitor errors in real-time:
|
188 |
+
```bash
|
189 |
+
tail -f results.jsonl | grep error
|
190 |
+
```
|
|
|
|
